  • A practical review on the measurement tools for cellular adhesion force
    • Abstract: Publication date: Available online 11 May 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Rita Ungai-Salánki, Beatrix Peter, Tamás Gerecsei, Norbert Orgovan, Robert Horvath, Bálint Szabó Cell–cell and cell–matrix adhesions are fundamental in all multicellular organisms. They play a key role in cellular growth, differentiation, pattern formation and migration. Cell-cell adhesion is substantial in the immune response, pathogen-host interactions, and tumor development. The success of tissue engineering and stem cell implantations strongly depends on the fine control of live cell adhesion on the surface of natural or biomimetic scaffolds. Therefore, the quantitative and precise measurement of the adhesion strength of living cells is critical, not only in basic research but in modern technologies, too. Several techniques have been developed or are under development to quantify cell adhesion. All of them have their pros and cons, which has to be carefully considered before the experiments and interpretation of the recorded data. Current review provides a guide to choose the appropriate technique to answer a specific biological question or to complete a biomedical test by measuring cell adhesion.Graphical abstractUnlabelled Image
       
  • Gum-based nanocarriers for the protection and delivery of food bioactive
           compounds
    • Abstract: Publication date: Available online 10 May 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Afsaneh Taheri, Seid Mahdi Jafari Gums, which for the most part are water-soluble polysaccharides, can interact with water to form viscous solutions, emulsions or gels. Their desirable properties, such as flexibility, biocompatibility, biodegradability, availability of reactive sites for molecular interactions and ease of use have led to their extremely large and broad applications in formation of nanostructures (nanoemulsions, nanoparticles, nanocomplexes, and nanofibers) and have already served as important wall materials for a variety of nano encapsulated food ingredients including flavoring agents, vitamins, minerals and essential fatty acids. The most common gums used in nano encapsulation systems include Arabic gum, carrageenan, xanthan, tragacanth plus some new sources of non-traditional gums, such as cress seed gum and Persian/or Angum gum identified as potential building blocks for nanostructured systems. New preparation techniques and sources of non-traditional gums are still being examined for commercialization in the food nanotechnology area as low-cost and reproducible sources. In this study, different nanostructures of gums and their preparation methods have been discussed along with a review of gum nanostructure applications for various food bioactive ingredients.Graphical abstractUnlabelled Image
       
  • To what extent do polymeric stabilizers affect nanoparticles
           characteristics'
    • Abstract: Publication date: Available online 10 May 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Metwally Madkour, Ali Bumajdad, Fakhreia Al-Sagheer Colloidal synthesis of nanoparticles using polymeric stabilizers as a template of a structure directing agent provided a plethora of opportunities in fabricating nanoparticles (NPs) with controlled size, shape, composition and structural characteristics. To understand the complete potency of polymeric stabilizers during the synthesis of nanoparticles, the relationship between polymer characteristics such as structure, molecular weight and concentration and nanoparticles characteristics is discussed in depth. This review portrays the use of polymers to attain nanostructured materials via covalent and non-covalent approaches. The effect provided by polymer are quite potent means that directs the formation of nanomaterials into desired forms that are otherwise hard to achieve. These polymers can also serve as surfaces modifier as well as the growth regulator during the synthesis of nanomaterials. We especially spotlight on the approaches for tuning the characteristic properties of nanoparticles via cautious choice of the polymer system with special focus to stimuli-responsive polymers. This review mainly focusses on answering the main challenging question; what is the ideal polymeric stabilizer system to obtain specific morphology, size and phase structure of nanoparticles? Such vital information will enable rational design of nanoparticles to meet specific needs for different applications.Graphical abstractUnlabelled Image
       
  • Food protein amyloid fibrils: Origin, structure, formation,
           characterization, applications and health implications
    • Abstract: Publication date: Available online 10 May 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Yiping Cao, Raffaele Mezzenga Amyloid fibrils have traditionally been considered only as pathological aggregates in human neurodegenerative diseases, but it is increasingly becoming clear that the propensity to form amyloid fibrils is a generic property for all proteins, including food proteins. Differently from the pathological amyloid fibrils, those derived from food proteins can be used as advanced materials in biomedicine, tissue engineering, environmental science, nanotechnology, material science as well as in food science, owing to a combination of highly desirable feature such as extreme aspect ratios, outstanding stiffness and a broad availability of functional groups on their surfaces. In food science, protein fibrillization is progressively recognized as an appealing strategy to broaden and improve food protein functionality. This review article discusses the various classes of reported food protein amyloid fibrils and their formation conditions. It furthermore considers amyloid fibrils in a broad context, from their structural characterization to their forming mechanisms and ensued physical properties, emphasizing their applications in food-related fields. Finally, the biological fate and the potential toxicity mechanisms of food amyloid fibrils are discussed, and an experimental protocol for their health safety validation is proposed in the concluding part of the review.Graphical abstractUnlabelled Image
       
  • Bridging the gap between two different scaling laws for structuring of
           liquids under geometrical confinement
    • Abstract: Publication date: Available online 10 May 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Michael Ludwig, Marcus U. Witt, Regine V. Klitzing Structural forces are a phenomena obtained in liquids of one-component (e.g. for organic solvents) and two-components (colloidal dispersions), alike. So far, those two systems were discussed separately, using two different scaling laws. In this review article, an attempt is made to bridge the gap between both scaling laws by defining the scaling limit for two-component systems. Colloidal probe atomic force microscopy (CP-AFM) is used to measure structural forces in suspensions of silica nanoparticles (NP) of three different sizes. In these two-component systems (solid NPs suspended in water), oscillatory behaviour can be obtained in the force vs. separation profiles. The wavelength λ is larger than the actual particle diameter d and rather depends on the particles' volume fraction ϕ following the inverse cubic root law λ∝ϕ−13. It is shown that the real particle diameter d can be determined by a gedankenexperiment by extrapolating the fitted wavelength λ from the structural force measurements at a specific particle concentration to a particle volume fraction ϕ of 52 % - the packing factor for simple cubic packing - using the well-known inverse cubic root scaling law. This extrapolation can be interpreted as a transition from a two-component system towards a one-component-like problem. In this case, particles are in contact and the wavelength λ is equal to the particle diameter d, λ = d as for one-component systems. The determined diameters d of the different silica nanoparticles agree well with independent measurements using transmission electron microscopy (TEM), validating the used approach. The proposed method can be extended to numerous dispersions of spherical nano-sized objects, for which structural forces can be measured.Graphical abstractUnlabelled Image
       
  • Formation and assembly of amphiphilic Janus nanoparticles promoted by
           polymer interactions
    • Abstract: Publication date: Available online 9 May 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Ana Maria Percebom, Lais Helena Moreira Costa Almost three decades after de Gennes have introduced the term Janus for particles possessing two faces with different chemical nature, Janus particles are currently a hot topic in itself. Although de Gennes was not concerned with the size of particles, due to the advent and perspectives of nanotechnology, nanosized Janus particles have particularly received great attention. The capacity of having two antagonistic properties within the same particle has attracted interest on Janus nanoparticles for innumerous potential applications. It took some years for the studies about Janus nanoparticles to finally see great advances, mainly due to the progress in nanoparticle synthesis. What de Gennes might have not predicted (or at least he did not mention it during his speech) is that intermolecular interactions between polymers would be of immense importance to the actual achievement of Janus nanoparticles. Moreover, these interactions can also have large effects on the assembly process of amphiphilic Janus nanoparticles, which is important to form hierarchical structures and new materials at different scales. Hence, it is interesting to notice that de Gennes' contribution for the polymer field has been influencing the preparation and the controlled assembly of Janus nanoparticles. This article attempts to summarize empirical studies where noncovalent forces between polymers played a role, either on the production of Janus nanoparticles or on their assembly.Graphical abstractUnlabelled Image
       
  • Electrophoretic deposition of photocatalytic materials
    • Abstract: Publication date: Available online 7 May 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Sergio Obregón, Gabriela Amor, Alejandro Vázquez Powdered photocatalytic materials have been successfully applied for the degradation of organic and inorganic pollutants as well as for hydrogen production and CO2 photo-reduction. However, the development of strategies for the preparation of photoactive coatings is a hot topic since it is a promising step for its use in photocatalytic reactors on an industrial scale. Electrophoretic deposition is a versatile technique capable to produce coatings of nanoparticles at a relative low cost and with an excellent quality and control of the deposited material. This work summarizes the fundamental aspects of the electrophoretic deposition process, as well as the latest contributions in the deposition of several photocatalytic materials including TiO2 and other UV-photocatalysts like ZnO, ZnS, SrTiO3 and PbMoO4 in addition to visible-light-driven photocatalysts such as Bi2O3, CdS, CdSe, g-C3N4, among others. Furthermore, the morphological features of the coatings along with the repercussion in the photocatalytic performance are issues discussed in the present review, based on the effect of the multiple parameters of the electrophoretic process such as the applied voltage, the deposition time, the inter-electrode distance, the concentration of the particles, the solvents and additives.Graphical abstractUnlabelled Image
       
  • Derivatization approaches and applications of pullulan
    • Abstract: Publication date: Available online 5 May 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Sanjay Tiwari, Rahul Patil, Sunil K. Dubey, Pratap Bahadur Pullulan (PUL), a linear exo-polysaccharide, is useful in industries as diverse as food, cosmetics and pharmaceuticals. PUL presents many favorable characteristics, such as renewable origin, biocompatibility, stability, hydrophilic nature, and availability of reactive sites for chemical modification. With an inherent affinity to asialoglycoprotein receptors, PUL can be used for targeted drug delivery to the liver. Besides, these primary properties have been combined with modern synthetic approaches for developing multifunctional biomaterials. This is evident from numerous studies on approaches, such as hydrophobic modification, cross-linking, grafting and transformation as a polyelectrolyte. In this review, we have discussed up-to-date advances on chemical modifications and emerging applications of PUL in targeted theranostics and tissue engineering. Besides, we offer an overview of its applications in food, cosmetics and environment remediation.Graphical abstractUnlabelled Image
       
  • Van der Waals forces in free and wetting liquid films
    • Abstract: Publication date: Available online 5 May 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Kirill A. Emelyanenko, Alexandre M. Emelyanenko, Ludmila B. Boinovich Van der Waals interactions induced by fluctuations of electromagnetic field bear universal nature and act between individual atoms, condensed particles or bodies of any type. Continuously growing interest to theoretical understanding as well as to precise evaluation of van der Waals forces is caused by their fundamental role in many physical, chemical, and biological processes. In this paper, we scrutinize progress in the studies of van der Waals forces, related to recent active development of Coupled Dipole Method (CDM) for the analysis of the behavior and properties of nanosized systems. The application of CDM for the analysis of thin liquid films allowed achieving substantial progress in understanding the behavior of free and wetting films. It was shown that both the macroscopic properties, such as excess free energy and Hamaker constants and the local microscopic parameters, such as polarizabilities, can be successfully calculated based only on properties of individual molecules. The impact of lateral film confinement on the specific excess free energy and the film stability was elucidated, and effect of spatial constraints on the spectrum of vibrational states for liquid film and the underlying substrate was analyzed. It was shown that van der Waals interactions between molecules represent the universal mechanism for dynamic structuring and formation of boundary layers and that the CDM allows self-consistently calculating the properties of these layers in both solid and liquid phases.Graphical abstractUnlabelled Image
       
  • Assembly behaviors of calixarene-based amphiphile and supra-amphiphile and
           the applications in drug delivery and protein recognition
    • Abstract: Publication date: Available online 3 May 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Jing Wang, Xin Ding, Xia Guo Calixarene is the third generation of supra-molecular compounds after crown ether and cyclodextrin. Amphiphilic calixarene can be obtained by modulation with both hydrophilic group and hydrophobic alkyl chain. Compared with conventional surfactant, amphiphilic calixarene has much lower critical micelle concentration and is much easier to self-assemble into different morphological aggregates. Calixarene-based supra-amphiphile can be designed via noncovalent bonds due to the capability of calixarene to recognize surfactant; the binding of a surfactant with calixarene can decrease the critical micelle concentration of surfactant by several times. The calixarene-surfactant complex can self-aggregate to form spherical micelles, vesicles, and spherical nanoparticles, and the aggregation behavior can be controlled by the structures and the molar ratio of surfactant to calixarene and environmental factors. Calixarene-based amphiphile and supra-amphiphile show low cytotoxicity. They can load drugs and assemble into nanocapsules with drugs. The structure of the calixarene-drug complex can respond to external stimuli, rendering the sustained release of the drug and suggesting its potential application as a drug delivery system. Recently, calixarene has also been found to selectively bind proteins, suggesting its prospect in disease diagnosis and intervention treatment in clinics. This review elaborates on the research progress in the self-assembly behaviors of calixarene-based amphiphile and supra-amphiphile and the applications of the calixarenes in drug delivery and protein recognition. The prospectives for the studies are also provided in this review.Graphical abstractUnlabelled Image

  • Polymer/nanodiamond composites - a comprehensive review from synthesis and
           fabrication to properties and applications
    • Abstract: Publication date: Available online 27 April 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Pooria Karami, Samaneh Salkhi Khasraghi, Mohammadjafar Hashemi, Sima Rabiei, Akbar Shojaei Nanodiamond (ND) is an allotrope of carbon nanomaterials which exhibits many outstanding physical, mechanical, thermal, optical and biocompatibility characteristics. Meanwhile, ND particles possess unique spherical shape containing diamond-like structure at the core with graphitic carbon outer shell which intuitively contains many oxygen-containing functional groups at the outer surface. Such superior properties and unique structural morphology of NDs are essentially attractive to develop polymer composites with multifunctional properties. However, despite a long history from the discovery of NDs, which is dated back to the1960s, this nanoparticle has been less explored in the field of polymer (nano)composites compared with other carbon nanomaterials, e.g. carbon nanotube (CNT) and graphene. However, open literature indicates that research works in the field of polymer/ND (PND) composites have gained great momentum in the past half a decade. The present article provides a comprehensive review on recent achievements in ND based polymer composites. This review covers a very broad aspect from the synthesis, purification and functionalization of NDs to dispersion, preparation and fabrication of polymer/ND (PND) composites with a look in their recent applications for both structural and functional basis. Therefore, the review would be useful to pave the way for researchers to take some advancing steps in this respect.Graphical abstractUnlabelled Image
       
  • Fouling and wetting in the membrane distillation driven wastewater
           reclamation process – A review
    • Abstract: Publication date: Available online 27 April 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Mahbuboor Rahman Choudhury, Nawrin Anwar, David Jassby, Md. Saifur Rahaman Fouling and wetting of membranes are significant concerns that can impede widespread application of the membrane distillation (MD) process during high-salinity wastewater reclamation. Fouling, caused by the accumulation of undesirable materials on the membrane surface and pores, causes a decrease in permeate flux. Whereas membrane wetting, the direct permeation of the feed solution through the membrane pores, results in reduced contaminant rejection and overall process failure. Lately, the application of MD for water recovery from various types of wastewaters has gained increased attention among researchers. In this review, we discuss fouling and wetting phenomena observed during the MD process, along with the effects of various mitigation strategies. In addition, we examine the interactions between contaminants and different types of MD membranes and the influence of different operating conditions on the occurrence of fouling and wetting. We also report on previously investigated feed pre-treatment options before MD, application of integrated MD processes, the performance of fabricated/modified MD membranes, and strategies for MD membrane maintenance during water reclamation. We also discussed energy consumption and economic aspects of MD for wastewater recovery. Throughout the review, we engage in discussions highlighting research needs for furthering the development of MD: notably the incorporation of MD in the overall wastewater treatment and recovery scheme (including selection of appropriate membrane material, suitable pre-treatment or integrated processes, and membrane maintenance strategies), and the application of MD in long-term pilot-scale studies using real wastewater.Graphical abstractUnlabelled Image
       
  • The importance of being amorphous: Calcium and magnesium phosphates in the
           human body
    • Abstract: Publication date: Available online 27 April 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Rita Gelli, Francesca Ridi, Piero Baglioni This article focuses on the relevance of amorphous calcium (and magnesium) phosphates in living organisms. Although crystalline calcium phosphate (CaP)-based materials are known to constitute the major inorganic constituents of human hard tissues, amorphous CaP-based structures, often in combination with magnesium, are frequently employed by Nature to build up components of our body and guarantee their proper functioning. After a brief description of amorphous calcium phosphate (ACP) formation mechanism and structure, this paper is focused on the stabilization strategies that can be used to enhance the lifetime of the poorly stable amorphous phase. The various locations of our body in which pure ACP, or in combination with Mg2+, can be found (i.e. bone, enamel, small intestine, calciprotein particles and casein micelles) are highlighted, showing how the amorphous nature of ACP is often of paramount importance for the achievement of a specific physiological function. The last section is devoted to ACP-based biomaterials, focusing on how these materials differ from their crystalline counterparts in terms of biological response.Graphical abstractUnlabelled Image
       
  • Surface topographies of biomimetic superamphiphobic materials: design
           criteria, fabrication and performance
    • Abstract: Publication date: Available online 27 April 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Xuelian Gou, Zhiguang Guo Superamphiphobicity is a wetting phenomenon that not only water but also oils or organic solvents with low surface tension exhibit large contact angles above 150° along with low contact angle hysteresis on solid surface. It is well known that both chemical constituent and surface roughness have impacts on the wettability of solid surface. Herein, several fundamental wetting states and design criteria for re-entrant structures are introduced first. Then, various chemical modification materials endowing solid substrates low surface energy are summarized subsequently. Furthermore, roughening processes conferring hierarchical or re-entrant topographic structures on surfaces are classified based on different types of topographies abstracted from the natural oil-repellent creatures (mushroom-like structures) as well as bio-inspired superamphiphobic surfaces (i.e., randomly distributed nanostructures, regularly patterned microstructures and other complex hierarchical structures). Significantly, the impalement pressure and formulated rules of various re-entrant profiles are recommended in detail. At the same time, fabrication, outstanding performances such as mechanical durability, chemical stability are also mentioned according to different types of morphologies. Beyond that, current fabrication obstacles and future prospects are proposed simultaneously in the end.Graphical abstractUnlabelled Image
       
  • Icephobic surfaces: Definition and figures of merit
    • Abstract: Publication date: Available online 27 April 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Peyman Irajizad, Sina Nazifi, Hadi Ghasemi Icephobic surfaces have a critical footprint on human daily lives ranging from aviation systems and infrastructures to energy systems, but creation of these surfaces for low-temperature applications remains elusive. Non-wetting, liquid-infused and hydrated surfaces have inspired routes for development of icephobic surfaces. However, high freezing temperature, high ice adhesion strength and subsequent ice accretion, low mechanical durability, and high production cost have restricted their practical applications. In this review, we provide a comprehensive definition for icephobicity through thermodynamics, heat transfer and mechanics of ice/water-material interface and elucidate physic-based routes through which nano-scale could help to achieve exceptional icephobic surfaces. Based on conservation laws, mathematical models are developed that accurately predict ice growth rate on various substrates and wind conditions. Through physics of fracture at ice-icephobic material interface, we cast a standard method for ice adhesion measurement that has the potential to eliminate discrepancies between reported ice adhesion from different laboratories. To assure long-time performance of icephobic surfaces, durability metrics need to be defined. We provide standard methods to examine mechanical, chemical, and environmental durability of icephobic surfaces. In the developed comprehensive framework on icephobicity in this review, performance of state-of-the-art icephobic surfaces are compared and main deficiencies in this field are highlighted.Graphical abstractUnlabelled Image
       
  • Multilayers formed by polyelectrolyte-surfactant and related mixtures at
           the air-water interface
    • Abstract: Publication date: Available online 19 April 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Peixun Li, Jeffery Penfold, Robert K. Thomas, Hui Xu The structure and occurrence of multilayered adsorption at the air-water interface of surfactants in combination with other oppositely charged species is reviewed. The main species that trigger multilayer formation are multiply charged metal, oligo- and polyions. The structures vary from the attachment of one or two more or less complete surfactant bilayers to the initial surfactant monolayer at the air-water interface to the attachment of a greater number of bilayers with a more defective structure. The majority of the wide range of observations of such structures have been made using neutron reflectometry. The possible mechanisms for the attraction of surfactant bilayers to an air-water interface are discussed and particular attention is given to the question of whether these structures are true equilibrium structures.Graphical abstractUnlabelled Image

Magnetic fields of ca 0.5 T give rise to near surface dips with a depth of dozens of microns. The physics and applications of direct and inverse Moses effects are reviewed, including trapping and self-assembly of particles. Experimental techniques enabling visualization of the effects are surveyed. The impact of a magnetic field on micro- and macroscopic properties of liquids is addressed. The influence of surface tension on the shape of the near-surface dip formed in a diamagnetic liquid by magnetic field is reported. Floating of diamagnetic bodies driven by the Moses effect is treated. The “magnetic memory of water” in relation to the Moses Effect is discussed. The dynamics of self-healing of near-surface dips due to the Moses Effect is considered.Graphical abstractUnlabelled Image
       
  • Rotator phases in alkane systems: In bulk, surface layers and
           micro/nano-confinements
    • Abstract: Publication date: Available online 5 April 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Diana Cholakova, Nikolai Denkov Medium- and long-chain alkanes and their mixtures possess a remarkable physical property – they form intermediate structured phases between their isotropic liquid phase and their fully ordered crystal phase. These intermediate phases are called “rotator phases” or “plastic phases” (soft solids) because the incorporated alkane molecules possess a long-range positional order while preserving certain mobility to rotate, which results in complex visco-plastic rheological behaviour. The current article presents a brief overview of our current understanding of the main phenomena involved in the formation of rotator phases from single alkanes and their mixtures. In bulk, five rotator phases with different structures were identified and studied in detail. Along with the thermodynamically stable rotator phases, metastable and transient (short living) rotator phases were observed. Bulk rotator phases provided important information about several interfacial phenomena of high scientific interest, such as the energy of crystal nucleation, entropy and enthalpy of alkane freezing, interfacial energy between a crystal and its melt, etc. In alkane mixtures, the region of existence of rotator phases increases significantly, reflecting the disturbed packing of different molecules. All these phenomena are very important in the context of alkane applications as lubricants, in cosmetics, as phase-change materials for energy storage, etc. Significant expansion of the domain of rotator phases was observed also in confinements – in the pores of solid materials impregnated with alkanes, in polymeric microcapsules containing alkanes, and in micrometer sized emulsion droplets. The rotator phases were invoked to explain the mechanisms of two recently discovered phenomena in cooled alkane-in-water emulsions – the spontaneous “self-shaping” and the spontaneous “self-bursting” (fragmentation) of emulsion drops. The so-called “α-phases” formed by fatty acids and alcohols, and the “gel phase” formed in phospholipid and soap systems exhibit structural characteristics similar to those in the alkane rotator phases. The subtle connections between all these diverse systems are outlined, providing a unified outlook of the main phenomena related to the formation of such soft solid materials. The occurrence of alkane rotator phases in natural materials and in several technological applications is also reviewed to illustrate the general importance of these unique materials and the related phenomena.Graphical abstractUnlabelled Image
       
  • Wettability of rock/CO2/brine and rock/oil/CO2-enriched-brine
           systems:Critical parametric analysis and future outlook
    • Abstract: Publication date: Available online 1 April 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Muhammad Arif, Sidqi Abu-Khamsin, Stefan Iglauer CO2 geo-sequestration is a promising technology to permanently store CO2 in geological formations to control the atmospheric carbon footprint. In addition, CO2 is frequently utilized in enhanced oil recovery operations to accelerate oil production. Both, CO2 geo-storage and EOR, are significantly influenced by the wettability of the associated rock/CO2/brine systems. Wettability drives the multiphase flow dynamics, and microscopic fluid distribution in the reservoir. Furthermore, while wettability is known to be influenced by varying in-situ conditions and surface chemistry of the rock/mineral, the current state-of-the-art indicates wider variabilities of the wetting states.This article, therefore, critically reviews the published datasets on CO2 wettability of geological formations. Essentially, the rock/CO2/brine and rock/crude-oil/CO2-enriched-brine contact angle datasets for the important reservoir rocks (i.e. sandstone and carbonate rocks), as well as for the key minerals quartz and calcite are considered. Also, the parameters that influence wettability are critically analyzed, and the associated parametric trends are discussed and summarized. Finally, we identify pertinent research gaps and define the outlook of future research. The review, therefore, establishes a repository of the recent contact angle data, which thus assists to enhance our current understanding of the subject.Graphical abstractUnlabelled Image
       
  • Colloids of detonation nanodiamond particles for advanced applications
    • Abstract: Publication date: Available online 26 March 2019Source: Advances in Colloid and Interface ScienceAuthor(s): A.V. Shvidchenko, E.D. Eidelman, A. Ya Vul', N.M. Kuznetsov, D. Yu Stolyarova, S.I. Belousov, S.N. Chvalun Nanodiamond (ND) is one of the most attractive allotropic modification of carbon due to their unique physical and chemical properties. In the present review the current state of science and technology in the field of NDs is analyzed. ND can be used in various application and in different form e.g. as a dispersion phase in suspension, as a filler in composites, etc., so the sedimentation stability of ND in different media are under scrutiny. Thus, theoretical aspects of ND suspension coagulation mechanisms and the methods avoiding it were considered. The dependence of rheological behavior on particles modification was discussed as well. Various methods for the preparation and modification of NDs to obtain particles of various sizes on a nanometer scale with different physicochemical properties were reviewed. The area of practical application for NDs was considered on the example of polymer composites. The various manufacturing methods, mechanical properties and medical aspects for thermosetting, thermoplastic and elastomer ND composites were summarized.Graphical abstractUnlabelled Image
       
  • On the stability of thin films of pure water
    • Abstract: Publication date: Available online 20 March 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Stoyan I. Karakashev, Mahshid Firouzi, Jianlong Wang, Lidia Alexandrova, Anh V. Nguyen The stability of water films has been the focus of many researchers in the recent decades. Unfortunately, there is no consensus on the stability of these foam films or on the mechanisms responsible for stabilizing water films. This paper examines the reported results on this matter and scrutinizes them based on speciation analysis of the dissolved species and the recent achievements in the adsorption of inorganic ions on the air/water interface. Our results confirm the key role of surface contamination, interface approach velocity and evaporation on the drainage and lifetime of these water films. It confirms the stabilizing effect of contamination and the destabilizing effect of air-water interface approach velocity. Moreover, the negative sign of the surface/zeta potential of the air/water interface and its dependence on the pH value were explained.Graphical abstractInterferogram of foam film of distilled water.Unlabelled Image
       
  • Hydration of Hofmeister ions
    • Abstract: Publication date: Available online 20 March 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Chang Q. Sun, Yongli Huang, Xi Zhang Water dissolves salt into ions and then hydrate the ions in an aqueous solution. Hydration of ions deforms the hydrogen bonding network and triggers the solution with what the pure water never shows such as conductivity, molecular diffusivity, thermal stability, surface stress, solubility, and viscosity, having enormous impact to many branches in biochemistry, chemistry, physics, and energy and environmental industry sectors. However, regulations for the solute-solute-solvent interactions are still open for exploration. From the perspective of the screened ionic polarization and O:H–O bond relaxation, this work features the recent progress and a perspective in understanding the hydration dynamics of Hofmeister ions in the typical YI, NaX, ZX2, and NaT salt solutions (Y = Li, Na, K, Rb, Cs; X = F, Cl, Br, I; Z = Mg, Ca, Ba, Sr; T = ClO4, NO3, HSO4, SCN). Phonon spectrometric analysis turned out the f(C) fraction of bond transition from the mode of deionized water to the hydrating. The linear f(C) ∝ C form features the invariant hydration volume of small cations that are fully-screened by their hydration H2O dipoles. The nonlinear f(C) ∝ 1 - exp.(-C/C0) form describes that the number insufficiency of the ordered hydrating H2O diploes partially screens the anions. Molecular anions show stronger yet shorter electric field of dipoles. The screened ionic polarization, inter-solute interaction, and O:H–O bond transition unify the solution conductivity, surface stress, viscosity, and critical energies for phase transition.Graphical abstractUnlabelled Image
       
  • Modelling nanofiltration of electrolyte solutions
    • Abstract: Publication date: Available online 13 March 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Andriy Yaroshchuk, Merlin L. Bruening, Emiliy Zholkovskiy This review critically examines current models for nanofiltration (NF) of electrolyte solutions. We start from linear irreversible thermodynamics, we derive a basic equation set for ion transfer in terms of gradients of ion electrochemical potentials and transmembrane volume flux. These equations are extended to the case of significant differences of thermodynamic forces across the membrane (continuous version of irreversible thermodynamics) and solved in quadratures for single salts and trace ions added to single salts in the case of macroscopically-homogeneous membranes. These solutions reduce to (quasi)analytical expressions in the popular Spiegler-Kedem approximation (composition-independent phenomenological coefficients), which we extend to the case of trace ions. This enables us to identify membrane properties (e.g. ion permeances, ion reflection coefficients, electrokinetic charge density) that control its performance in NF of multi-ion solutions.Further, we specify the phenomenological coefficients of irreversible thermodynamics in terms of ion partitioning, hindrance and diffusion coefficients for the model of straight cylindrical capillaries. The corresponding expressions enable assessment of the applicability of the popular nanopore model of NF. This model (based on the use of macroscopic approaches at nanoscale) leads to a number of trends that have never been observed experimentally. We also show that the use of the Born formula (frequently employed for the description of dielectric exclusion) hardly leads to meaningful values of solvent dielectric constant in membrane pores because this formula disregards the very solvent structure whose changes are supposed to bring about the reduction of dielectric permittivity in nanopores. We conclude that the effect should better be quantified in terms of ion excess solvation energies in the membrane phase.As an alternative to the nanopore description of NF, we review recent work on the development of an advanced engineering model for NF of multi-ion solutions in terms of a solution-diffusion-electromigration mechanism. This model (taking into account spontaneously arising transmembrane electric fields) captures several trends observed experimentally, and the use of trace ions can provide model parameters (ion permeances in the membrane) from experiment. We also consider a recent model (ultrathin barrier layers with deviations from local electroneutrality) that may reproduce observed feed-salt concentration dependences of membrane performance in terms of concentration-independent properties like excess ion solvation energies.Due to its complexity, practical modelling of nanofiltration will probably be performed with advanced engineering models for the foreseeable future. Although mechanistic studies are vital for understanding transport and developing membranes, future simulations in this area will likely need to depart from typical continuum models to provide physical insight. For enhancing the quality of modelling input, it is essential to improve the control of concentration polarization in membrane test cells.Graphical abstractUnlabelled Image
       
  • Waterproof breathable layers – A review
    • Abstract: Publication date: Available online 13 March 2019Source: Advances in Colloid and Interface ScienceAuthor(s): Ali Reza Tehrani-Bagha Waterproof breathable layers (WPBLs) can be classified into two large groups of hydrophilic nonporous and hydrophobic porous layers. These layers (e.g., fabrics, films, membranes, and meshes) can be produced by various continuous and non-continuous processes such as coating, laminating, film stretching, casting, etc. The most common methods for production, characterization, and testing of WPBLs are presented and discussed in light of recent publications. The materials with high level of waterproofness and breathability are demanded in many applications. A widely used application of WPBLs is in outwear for winter sports, sailing apparel, raincoats, military/police jackets, backpacks, tents, cargo raps, footwear and etc. WPBLs can also be used for other specialized applications such as membrane distillation, oil-water filtration, and wound dressing which entail more features and functionalities. The main challenge in production of these layers is to compromise between waterproofness and breathability with opposing nature. The related research gaps and challenges are highlighted to shed more light on the topic.Graphical abstractUnlabelled Image
