  • Recent advances in polymerizations in dispersed media
    • Abstract: Publication date: Available online 9 August 2018Source: Advances in Colloid and Interface ScienceAuthor(s): Ratchapol Jenjob, Farzad Seidi, Daniel CrespyAdvances in chemistry heterophase polymerizations reflect new developments in polymer chemistry. Although some few polymerization reactions cannot be performed in dispersed media, new polymerization reactions can still benefit from advantages of heterophase reactions, which are fast kinetics due to high local concentration of reagents and advantageous heat exchange. We describe here advances in heterophase polymerizations, with a focus on miniemulsion polymerization, which are mainly driven by academic interest for biomedicine and energy science. Click-reactions in dispersion are particularly interesting because they are bioorthogonals. Synthesis of highly crosslinked polymer colloids, especially with conjugated polymers, has found applications in gas storage, catalysis, and production of energy. Finally, we show how spatial segregation in heterophase polymerization can help to obtain polymer materials with unique structures.Graphical abstractUnlabelled Image
       
  • Engineering intelligent particle-lipid composites that control
           lipase-mediated digestion
    • Abstract: Publication date: Available online 6 August 2018Source: Advances in Colloid and Interface ScienceAuthor(s): Paul Joyce, Hanna Gustafsson, Clive A. PrestidgeNanostructured particle-lipid composites have emerged as state-of-the-art carrier systems for poorly water-soluble bioactive molecules due to their ability to control and enhance the lipase-mediated hydrolysis of encapsulated triglycerides, leading to a subsequent improvement in the solubilisation and absorption of encapsulated species. The first generation of particle-lipid composites (i.e. silica-lipid hybrid (SLH) microparticles) were designed and fabricated by spray drying a silica nanoparticle-stabilised Pickering emulsion, to create a novel three-dimensional architecture, whereby lipid droplets were encapsulated within a porous matrix support. The development of SLH microparticles has acted as a solid foundation for the synthesis of several next generation particle-lipid composites, including polymer-lipid hybrid (PLH) and clay-lipid hybrid systems (CLH), which present lipase with unique lipid microenvironments for optimised lipolysis. This review details the methods utilised to engineer lipid hybrid particles and the strategic investigations that have been performed to determine the influence of key material characteristics on digestion enzyme activity. In doing so, this provides insight into manipulating the mechanism of lipase action through the intelligent design of lipid-based biomaterials for their use in drug delivery formulations and novel functional foods.Graphical abstractUnlabelled Image
       
  • Flexible electrochromic materials based on CNT/PDA hybrids
    • Abstract: Publication date: Available online 24 July 2018Source: Advances in Colloid and Interface ScienceAuthor(s): Reinack Varghese Hansen, Jinglei Yang, Lianxi ZhengMaterials that change color in response to external stimuli can cater to diverse applications from sensing to art. If made flexible, stretchable and weavable, they may even be directly integrated with advanced technologies such as smart textiles. A new class of engineered composite based on polydiacetylene (PDA) functionalized carbon nanotubes (CNT) shows tremendous potential in this regard. While the inherent multi stimuli chromatic response of the polymer (blue to red) is retained, the underlying conducting CNTs invoke electrochromism in PDA. Further, the fiber form factor of dry-spun CNT yarns facilitate direct weaving of large scale electrochromic fabrics, where current flow and thus color change can be accurately controlled. This review summarizes the fundamental aspects of CNT yarns and PDAs, focusing especially on their interaction chemistry which results in the scientifically and commercially appealing electrochromic transition in these hybrids.Graphical abstractUnlabelled Image
       
  • Developments in support materials for immobilization of oxidoreductases: A
           comprehensive review
    • Abstract: Publication date: Available online 24 July 2018Source: Advances in Colloid and Interface ScienceAuthor(s): Jakub Zdarta, Anne S. Meyer, Teofil Jesionowski, Manuel PineloBioremediation, a biologically mediated transformation or degradation of persistent chemicals into nonhazardous or less-hazardous substances, has been recognized as a key strategy to control levels of pollutants in water and soils. The use of enzymes, notably oxidoreductases such as laccases, tyrosinase, various oxygenases, aromatic dioxygenases, and different peroxidases (all of EC class 1) is receiving significant research attention in this regard. It should be stated that immobilization is emphasized as a powerful tool for enhancement of enzyme activity and stability as well as for protection of the enzyme proteins against negative effects of harsh reaction conditions. As proper selection of support materials for immobilization and their performance is overlooked when it comes to comparing performance of immobilized enzyme in academic studies, this review summarizes the current state of knowledge regarding the materials used for enzyme immobilization of these oxidoreductase enzymes for environmental applications. In the presented study, thorough physicochemical characteristics of the support materials was presented. Moreover, various types of reactions and notably operational modes of enzymatic processes for biodegradation of harmful pollutants are summarized, and future trends in use of immobilized oxidoreductases for environmental applications are discussed. Our goal is to provide an improved foundation on which new technological advancements can be made to achieve efficient enzyme-assisted bioremediation.Graphical abstractUnlabelled Image
       
  • Mesoscopic characterization of amphiphilic monoglycerol monolayers
    • Abstract: Publication date: Available online 22 July 2018Source: Advances in Colloid and Interface ScienceAuthor(s): D. VollhardtThe introduction of the highly-sensitive imaging technique Brewster angle microscopy (BAM) has given rise to new knowledges about the mesoscopic topology and ordering of condensed phase domains formed in the two-phase coexistence region of Langmuir monolayers. Besides fatty acids, monoalkanoylglycerols are the most studied amphiphiles at the air−water interface. In this review, the mesoscopic characterization of amphiphilic monoglycerol monolayers is surveyed to demonstrate the striking effect of the position of the glycerol backbone at which the polar head group is substituted. Systematic mesoscopic studies of amphiphilic monoglycerol monolayers offer an outstanding possibility to highlight the dramatic effect of chemical structure variations at the position of the glycerol backbone and the substituted polar groups on the basis of the mesoscopic characterization. Small changes in the polarity by slight variation in the head group structure can dramatic affect shape and organization of the condensed phase domains. According to the importance of the 1-substituted monoglycerols, the effect of the chemical structure of the substituted polar group is highlighted with 4 selected examples. Further main topics discussed are chiral discrimination, kinetics of non-equilibrium structures, electrostatic interactions and a new geometric concept for explaining the topology of condensed phase domains.Graphical abstractUnlabelled Image

    • Abstract: Publication date: Available online 19 July 2018Source: Advances in Colloid and Interface ScienceAuthor(s): Manpreet Kaur, Manmeet Kaur, Virender K. SharmaDoping of nitrogen is a promising strategy to modulate chemical, electronic, and structural functionalities of graphene (G)and graphene quantum dots (GQDs) for their outstanding properties in energy and environmental applications.This paper reviews various synthesis approaches of nitrogen-doped graphene (N-G) and nitrogen-doped graphene quantum dots (N-GQDs).;Thermal, ultrasonic, solvothermal, hydrothermal, and electron-beam methods have been applied to synthesize N-G and N-GQDs.These nitrogen-doped carbon materials are characterized to obtain their structural configurations in order to achieve better performance in their applications compared to only either graphene or graphene quantum dots.Both N-G and N-GQDs may be converted into functional materials by integrating with other compounds such as metal oxides/nitrides, polymers, and semiconductors.These functional materials demonstrate superior performance over N-G and N-GQDs materials.Examples of applications of N-G and N-GQDs include supercapacitors, batteries, sensors, fuel cells, solar cells, and photocatalyst.Graphical abstractUnlabelled Image
       
  • Microrheology, advances in methods and insights
    • Abstract: Publication date: July 2018Source: Advances in Colloid and Interface Science, Volume 257Author(s): Qiuyang Xia, Huining Xiao, Yuanfeng Pan, Lidong WangMicrorheology is an emerging technique that probes mechanical response of soft material at micro-scale. Generally, microrheology technique can be divided into active and passive versions. During last two decades, extensive efforts have been paid to improve both the experiment techniques and data analysis methods, especially about how to link consequential particle positions into trajectories. We review the recent advances in microrheology, including improvements in labeling, imaging, data acquiring, data processing and data interpretation. Some of the recent insights in soft matter and living systems gained by using this technique are given. Before these, we also give a very brief description of the basic principles of both active and passive microrheology techniques, and some details about optical particle tracking and DWS.Graphical abstractUnlabelled Image
       
  • Wall slip for complex liquids – Phenomenon and its causes
    • Abstract: Publication date: July 2018Source: Advances in Colloid and Interface Science, Volume 257Author(s): A. Ya Malkin, S.A. PatlazhanIn this review, we tried to qualify different types and mechanisms of wall slip phenomenon, paying particular attention to the most recent publications and issues. The review covers all type of fluids – homogeneous low molecular weight liquids, polymer solution, multi-component dispersed media, and polymer melts. We focused on two basic concepts - fluid-solid wall interaction and shear-induced fluid-to-solid transitions - which are the dominant mechanisms of wall slip.In the first part of the review, the theoretical and numerical studies of correlation of wetting properties and wall slip of low molecular weight liquids and polymeric fluids are reviewed along with some basic experimental results. The influence of nanobubbles and microcavities on the effectiveness of wall slip is illuminated with regard to the bubble dynamics, as well as their stability at smooth and rough interfaces, including superhydrophobic surfaces.Flow of multi-component matter (microgel pastes, concentrated suspensions of solid particles, compressed emulsions, and colloidal systems) is accompanied by wall slip in two cases. The first one is typical of viscoplastic media which can exist in two different physical states, as solid-like below the yield point and liquid-like at the applied stresses exceeding this threshold. Slip takes place at low stresses. The second case is related to the transition from fluid to solid states at high deformation rates or large deformations caused by the strain-induced glass transition of concentrated dispersions. In the latter case, the wall effects consist of apparent slip due to the formation of a low viscous thin layer of fluid at the wall.The liquid-to-solid transition is also a dominant mechanism in wall slip of polymer melts because liquid polymers are elastic fluids which can be in two relaxation states depending on the strain rate. The realization of these mechanisms is determined by polymer melt interaction with the solid wall.Graphical abstractUnlabelled Image
       
  • Polyphenols at interfaces
    • Abstract: Publication date: July 2018Source: Advances in Colloid and Interface Science, Volume 257Author(s): François Reitzer, Manon Allais, Vincent Ball, Florent MeyerPolyphenols are important molecules in living organisms, particularly in plants, where they serve as protectants against predators. They are also of fundamental importance in pharmacology for their antioxidant and antibacterial activities. Since a few years polyphenols are also used in surface functionalization mimicking the tannin deposition observed when tea or red wine are in contact with the surface of cups or glasses respectively. The interaction of polyphenols with proteins to yield colloids and of polyphenol with surfaces will be reviewed in this article to provide an overview of such particles and surface functionalization methods in modern surface science. Particular emphasis will be given to biological applications of polyphenols at interfaces.Graphical abstractUnlabelled Image
       
  • A comprehensive review on rheological studies of sludge from various
           sections of municipal wastewater treatment plants for enhancement of
           process performance
    • Abstract: Publication date: July 2018Source: Advances in Colloid and Interface Science, Volume 257Author(s): Eugene Hong, Anteneh Mesfin Yeneneh, Tushar Kanti Sen, Ha Ming Ang, Ahmet KayaalpLarge quantities of sludge is generated from different sections of a wastewater treatment plant operation. Sludge can be a solid, semisolid or liquid muddy residual material. Understanding the flow behaviour and rheological properties of sewage sludge at different sections of a wastewater treatment plant (WWTP) is important for the design of pumping system, mixing, hydrodynamics and mass transfer rates of various sludge treatment units, optimization of conditioning dose and for sustainable sludge management. The current article provides a comprehensive review on up to date literature information on rheological behaviour of raw primary sludge, excess activated sludge, thickened excess activated sludge, mixture of raw primary and thickened excess activated sludge (mixed sludge), digested sludge, and biosolid under the influence of different operating parameters and their impacts on process performance. The influences of various process parameters such as solid concentration, temperature, pH, floc particle size, primary to secondary sludge mixing ratio, aging and conditioning agent doses on the rheological behaviour of sludge from different treatment units of WWTPs are critically analysed here. Yield stress was reported to increase with increasing solid concentration for all types of sludge whereas viscosity showed a decreasing trend with decreasing total solid concentration and percentage of thickened excess activated sludge in the mixture. Temperature showed an inverse relationship with yield stress and viscosity. Viscosity was reported to be decreased with decrease in pH. The effect of various conditioning agents on the rheological behaviour of sludge are also discussed here. The applicability and practical significance of various rheological models such as Bingham, Power Law (Ostwald), Herschel-Bulkley, Casson, Sisko, Careau, and Cross models to experimental rheological characteristics of various sludges were presented here. The reported results on various rheological parameters such as shear stress, yield stress, flow index, infinite, zero-rate viscosity, and flow consistency index of different sludge types obtained from the best fitted model were also compiled here. Conclusions have been drawn from the literature reviewed and few suggestions for future research direction are proposed.Graphical abstractUnlabelled Image
       
  • PAMAM dendrimer - cell membrane interactions
    • Abstract: Publication date: July 2018Source: Advances in Colloid and Interface Science, Volume 257Author(s): Laura J. Fox, Robert M. Richardson, Wuge H. BriscoePAMAM dendrimers have been conjectured for a wide range of biomedical applications due to their tuneable physicochemical properties. However, their application has been hindered by uncertainties in their cytotoxicity, which is influenced by dendrimer generation (i.e. size and surface group density), surface chemistry, and dosage, as well as cell specificity. In this review, biomedical applications of polyamidoamine (PAMAM) dendrimers and some related cytotoxicity studies are first outlined. Alongside these in vitro experiments, lipid membranes such as supported lipid bilayers (SLBs), liposomes, and Langmuir monolayers have been used as cell membrane models to study PAMAM dendrimer-membrane interactions. Related experimental and theoretical studies are summarized, and the physical insights from these studies are discussed to shed light on the fundamental understanding of PAMAM dendrimer-cell membrane interactions. We conclude with a summary of some questions that call for further investigations.Graphical abstractUnlabelled Image
       
  • Halloysite clay nanotubes for life sciences applications: From drug
           encapsulation to bioscaffold
    • Abstract: Publication date: July 2018Source: Advances in Colloid and Interface Science, Volume 257Author(s): Ana C. Santos, Carolina Ferreira, Francisco Veiga, António J. Ribeiro, Abhishek Panchal, Yuri Lvov, Anshul AgarwalNatural forming clay halloysite is an emerging nanomaterial carrier for sustained drug delivery. These 50 nm diameter aluminosilicate tubes, with inner - alumina and outer - silica surface layers, can be loaded with 10–30 wt% of drug molecules, DNA and enzymes. The opposite charge of the inner and outer halloysite surface allow for selective drug adsorption inside or outside the clay nanotubes. The drug loaded halloysite enhanced the zeta potential of minus 50–60 mV allowing for stable aqueous nanocolloids. Halloysite nanoformulations provide an extended 10–20 h release profile, and may be functionalized (e.g., clogging tubes' end with polymers extending release time to 1–2 weeks or allowing for triggered release), which renders these clay nanostructures as promising controlled delivery systems. Recent studies demonstrate the potential of abundantly available halloysite clay nanotubes for life science applications, from drug delivery via oral or topical administration, to tissue scaffolds and regenerative medicine, while assessing their cellular internalization, stability, biosafety and biocompatibility are featured. The benefits and limitations of halloysite clay nanotubes are discussed, as well as the directions for future developments.Graphical abstractUnlabelled Image
       
  • Orientation phase transitions of undissociated n-decanoic acid at the
           air/solution interface revealed by surface pressure and electric potential
           
    • Abstract: Publication date: Available online 23 June 2018Source: Advances in Colloid and Interface ScienceAuthor(s): Wanda Barzyk, Klaus Lunkenheimer, Andrzej PomianowskiThe surface pressure (Π) and electric surface potential (ΔV) vs. concentration (c) isotherms of n-decanoic acid (DA) in 1 × 10−3 mol/dm3 HCl were measured at the air/solution interface - the Π with a du Noüy ring, the ΔV with the vibrating plate (named also the dynamic condenser) method. The DA solutions fulfilled criterion of surface-chemical purity. The complementary Π-c and ΔV-c isotherms were jointly evaluated to obtain dependence of quotient of the effective dipole moment to the interface's permittivity, μ⊥/εs, as a function of chosen adsorption ordinates such as the bulk concentration, c, partial molar area, A, and surface molar fraction of DA, XDAs. The crucial point for the analysis is knowledge of the surface excess (Γ) dependence on concentration (c). Since, experimental determination of a Γ-c course is problematic, so far, we used Γ-c courses calculated basing on different adsorption models (Gibbsian, the classical Frumkin’ model and the Lunkenheimer’ and Hirte’ two state approach). Despite, the Γ-c courses determined basing on the different adsorption models differ significantly, the μ⊥/εs dependences on different adsorption's ordinates (c, A or XDAs) revealed consistently three local μ⊥/εs maxima of their height increasing with the adsorption coverage. The μ⊥/εs change was recalculated into inclination angle (αincl) of the total dipole moment vector (μ→) to the interface, assuming εs = 1. The μ⊥/εs which reflects polarization orientation is an order parameter used by us for analysis of 2D phase transitions in the monolayer. The three μ⊥/εs local maxima are ascribed by us to three 2D mono-phases, one transferring into the next one of the higher order in the sequence: liquid expanded (L1) → the liquid condensed tilted (L2) → the liquid condensed untilted (L2′). One inflection point appearing in the Π-A isotherm within the region between the μ⊥/εs maxima 2 and 3 indicates that transition of the L2 into the L2’ 2D phase is of the first order. Decrease of the μ⊥/εs above the maximum 3 indicates transition into two phase regime by nucleation of aggregates (possibly in form of lamellas) within the L2′ phase.Graphical abstractChange of the effective dipole moment, μ⊥/εs, versus the bulk concentraqtion, c, of undissociated n-decanoic acid at the air/solution interface, at 25oC, indicates three 2D phase transitions between the monophases reflected in the local maxima of μ⊥/εs vs. c, namely: liquid expanded → liquid condensed tilted → liquid condensed untilted.Within the higher concn. region, the liquid condensed untilted coexists with 2D aggregates.Unlabelled Image
       
  • Evaluation of particle charging in non-aqueous suspensions
    • Abstract: Publication date: Available online 19 June 2018Source: Advances in Colloid and Interface ScienceAuthor(s): Jarl B. RosenholmFactors influencing the sign and size of effective surface (zeta) potential in suspensions of very low dielectric constants are evaluated. For non-aqueous suspensions it was found that Gutmann's donor number (DN = negative Lewis type molar acid-base adduct formation enthalpy) was successfully related to zeta potential changes, similarily as pH is optimal for aqueous suspensions. Negative molar proton dissociation enthalpy (Brϕnsted type HD number), negative hydrogen bond enthalpy (HB number), logarithmic hydrogen bond equilibrium constant (molar Gibbs free energy), standard reduction potential of solvated protons (Eo(HL+/H2)), electrolytic dissociation potential of water (Eo(H2O/H2, O2)) and electron exchange Fermi potentials could equally well be related to zeta potential changes. All these properties were linearly dependent on each other. Correlations to products of Gutmann's DN and AN numbers and other relevant properties such as polar, hydrogen bond and acid-base contributions to solubility parameters and surface tensions were found to be less successful particularly when very polar liquids were encountered. Commonly used DLVO models for repulsive interaction energy between particles in aqueous electrolyte suspensions have been simplified when dealing with low-polar, non-polar and apolar suspensions. When evaluating factors contributing to attractive and repulsive interaction energies, it is found that in order for the models to be relevant the extension of diffuse charging has to be much larger than the distance to repulsive barrier ensuring suspension stability. At this limit and at high surface potentials, the repulsive energy grows exceptionally large being in the range of lattice energy of each solid. The models fail when surface potential is low and the extension of diffuse charging is much smaller than the distance to repulsive barrier. Then interaction energies are reasonable. The investigated Au, SiO2, Glass, TiO2, Al2O3, CaCO3, MgO suspensions fall between these limits. The attractive energy is small but significant as compared to repulsive energy. All energies were larger than the estimated lower limit for stable suspensions.Graphical abstractUnlabelled Image
