      Pages: 1 - 8
      Abstract: Yarns obtained from natural fibers have been played a significant role in human history for the manufacture of technical and conventional textiles. Enset yarn is manufactured from agro waste fiber called false banana fiber (enset fiber). Fiber and/or yarn is not effectively utilized in technical textile and textile fiber reinforced ecofriendly composites. This research work was focused on the effect of biochemical modification of enset yarn, morphological analysis and characterized the mechanical properties of the yarn. Chemical composition, morphological structure and tensile strength were investigated and studied by using Fourier Transfer Infrared (FTIR), Scanning Electron Microscope (SEM) and SHIMADZU Strength tester. The tensile strength of the yarns were evaluated before and after biochemical treatments. The result show that, enset yarns treated with caustic soda, amylase enzyme and Aloe-vera gel were exhibited a significant improvement in their morphological, tensile strength and weight loss as compared to untreated enset yarn. The test results shown that treated enset yarn with both chemical and enzyme had a tensile strength of 53.50 – 65.43 MP with lower percentage weight loss. The tensile strength of the yarn was improved by 22 % due to alkalization and softeners. The major weight loss (6.14 %) enset yarn was observed in both 7.5% w/v. of alkali and 20% w/v. of enzyme treatment.

  • Nano materials-based devices by photodynamic therapy for treating cancer

    • Authors: Sargol Mazraedoost, Gity Behbudi
      Pages: 9 - 21
      Abstract:       Photodynamic therapy (PDT) is a non-invasive beneficial modality that is able to be used instead of radiotherapy and chemotherapy to treat cancer. Low water solubility makes administering photosensitizers (PSs) complicated, which undermines several molecules' medicinal application, limits PDT's efficacy. Nanotechnology can be used to tune the photoactive drug's pharmacokinetics and tumor selectivity and perform a vital role in the photosensitizer's photodynamic function by maintaining the photosensitizer's monomeric structure and thereby optimizing the photochemistry that occurs upon photon absorption. Also, nanotechnology-based drug delivery systems may progress a PS's transcytosis by allowing two or different drugs to be delivered at the same time via epithelial and endothelial barriers. Based on this, nanotechnology's application in medicine could open up a slew of novel cancer treatment possibilities while also improving the efficacy of presently available medicines. Consequently, this research aims to investigate nanotechnology-based medication conveyance instruments utilized for photodynamic cancer treatment.

      Pages: 15 - 23
      Abstract: In the current study to increase the release ability of acrylamide-based hydrogels, modified acrylamide-based hydrogel nanocomposites were synthesized and Montmorillonite, Kaolinite, and Illite were added to the matrix. The characterization of the clays was carried out using EDX and XRD, whereas the characterization of the clay-hydrogels was carried out with Fourier transform infrared spectroscopy (FTIR), Field Emission Scanning Electron Microscope (FESEM), swelling ratio, and rheology measurements. EDX of clays showed that the highest amount of Al (17.18 0.12%) is for Kaolinite and the highest amount of Si (20.94 0.85%) and Fe (8.53 %) belongs to Illite. The highest amount of C (6.97 1.54%) is for Montmorillonite. The swelling of Montmorillonite/Aam hydrogels including was found to be higher than other types of hydrogels used in this study. The shifting of the bonds in FTIR and FESEM images of composites showed that the clays are well-incorporated to the polymer and the shape of the composites in the FESEM images indicates the effect of clays on the structure of polymers. The highest swelling ratio was attributed to Montmorillonite/Aam composite. The frequency sweep test showed that the G’ and G” value of the Illite/Aam G’ (1260 36.5 Pa) and (198.5 6.6 Pa) was higher than the other mixtures.

           Nanocomposite with Multi-Walled Carbon Nanotubes

    • Authors: Alireza Aghili, Mohammad Reza Kamrani
      Pages: 22 - 34
      Abstract: Modeling of non-isothermal degradation of polymers consists of the integration of the Arrhenius function which has no analytical solution. The integration is commonly estimated by a variety of approximation functions with varying complexity and precision. In this study, a mathematical formula was derived in which the Arrhenius integral is calculated without using common approximation functions. Calculations showed that the obtained formula has a better accuracy compared to the common approximation functions. The obtained formula was used to determine the kinetic parameters of thermal degradation of poly (methyl methacrylate) (PMMA) and its nanocomposite with multi-walled carbon nanotubes (MWNT). The kinetic parameters were also calculated by a different method which was based on a single point calculation and used the approximation functions for estimating the Arrhenius integral. The comparison showed that there is a better agreement between the experimentally measured and calculated data when the kinetic parameters obtained from new formula.

    • Authors: Hossein Azimi, Mitra Tavakoli, Mehdi Sharifian
      Pages: 41 - 48
      Abstract: The plasma treatment is an efficient method used for improving wettability of the polymer film surface and increasing the surface roughness. In this paper, polypropylene (PP) films are modified by a dielectric barrier discharge (DBD) Plasma in the presence of air and nitrogen separately at atmospheric pressure. The plasma-modified surfaces are characterized by contact angle measurements, Atomic Force Microscopy (AFM) and Diffuse Reflectance Spectroscopy (DRS). Results show a remarkable increase in hydrophilicity due to the implantation of oxygen and nitrogen containing groups in these modified polypropylene films. Atomic oxygen, atomic nitrogen, OH radicals, and ions, which are presented in the discharge, create radicals at the polymer surface, which can react with oxygen and nitrogen species, resulting in formation of oxygen and nitrogen containing functionalities on the polymer surface. It is shown that plasma in the nitrogen atmosphere is more efficient in etching and implanting functionalities than air plasma.

  • Recent advancements in Graphene oxide-based for fight with HIV infection .

      Pages: 47 - 52
      Abstract: ABSTRACT The only successful trial to date against the HIV is the RV144 trials, and today, due to the role that broadly neutralizing antibodies (bnAbs) naturally plays in the fight against the HIV, scientists are working to develop bnAbs -induced vaccines to prevent HIV infection. Electrochemical sensors along with nanomaterial’s have been tested for faster detection of the HIV in the body. Among these sensors, electrochemically reduced graphene oxide (ERGO), glassy carbon modified with polyaniline/graphene (PAN/GN/GCE), and GCE modified with amino- reduced graphene oxide (NH2)- rGO and β –cyclodextrin (β-CD) (NH2-rGO/ β-CD/ GCE) are listed in this review. Today, antiretroviral therapy (ART) and highly active antiretroviral therapy (HAART) are used to treat the HIV, which are not able to completely cure the HIV infection. The main problem with the complete elimination of the HIV is the presence of the HIV latent reservoirs in the body. To this end, several strategies have been used to completely destroy these reservoirs, including "shock and kill" therapy approach, immunotherapy, and gene therapy. Keywords: HIV vaccine, ERGO, PAN/GN/GCE, NH2-rGO/ β-CD/ GCE, shock and kill, immunotherapy, gene therapy.

  • Influence of phosphor precursors on the morphology and purity of
           sol–gel-derived hydroxyapatite nanoparticles

    • Authors: Khadije Yousefi, Alireza Khalife
      Pages: 49 - 52
      Abstract:    In this study nano crystalline hydroxyapatite (HA) particles were produced by both sol-gel and precipitation methods. For this purpose calcium nitrate tetra hydrate (Ca(NO3)2·4H2O) was selected as calcium precursors  and three types of phosphorus precursors such as acid phosphoric (H3PO4) , triethyl phosphate  (C2H5O)3PO and pentad oxide phosphorus (P2O5) were chosen. The produced powders were characterized by X-ray diffraction (XRD), and scanning electron microscopy (SEM). The results show that although hydroxyapatite can be produced by all phosphorus precursors used in the current research, the purity of HA obtained from penta oxide phosphorus and phosphoric acid is higher than that of triethyl phosphate. The SEM micrographs prove that the morphology of nano-HAP depends on the type of phosphorus precursor .The HAP prepared from acid phosphoric was spherically shaped whereas the one from triethyl phosphate  is needle like and  from penta oxide phosphorus was found to be Pyramidal in shape.

      Abstract: Objective: Early diagnosis is life-saving in spinal muscular atrophy (SMA), a disease that is defined as a rare disease in the community and affects one person in ten thousand. When laboratory tests are examined from the diagnostic tests, it should be checked whether there is a homozygous deletion of the survival motor neuron 1 (SMN1) gene as the first diagnostic parameter for a patient who is thought to have spinal muscular atrophy (SMA). In order t o be sure of the diagnosis, it is necessary to look at the creatine kinase (CK) value of the patient and the nerve conduction results that will be obtained from the results of electrophysiological tests such as electromyography (EMG). It was aimed to develop an early diagnosis algorithm by using a mathematical ratio model to diagnose spinal muscular atrophy disease early, by proportioning the length of the electrocardiogram (ECG) frequency with the creatine kinase value being higher than normal.   Material and Method: A group of people with SMA disease and a group of healthy people were used in the study. Serum creatine kinase values of all patients were measured and the length of the electrocardiogram (ECG) frequency was measured. These two values are proportioned.   Result and Discussion: As a result of literature studies, the frequencies of electrocardiogram tremors and creatine kinase (CK) values of healthy people were compared. Electrocardiogram (ECG) frequencies and creatine kinase values of sick people were also compared. The range value of healthy people and the range values of sick people were compared and a range of values specific to sick people was determined. Based on this range, patients with vibration frequency / creatine kinase values between 0.125-0.175 can be diagnosed. This study will contribute to the development of computer-based android applications for diagnosis for patients with spinal muscular atrophy (SMA) with codes 0 and 1, using the inference that the patient is healthy as the value approaches 1 and the value approaches 0.

  • Providing a model to robust entanglement between a movable mirror and a
           cavity field in coupled optomechanical system

    • Authors: Mehrad Gavahi, Li hong Rong
      Pages: 68 - 76
      Abstract: Einstein, Podolsky, and Rosen and Schr ̈odinger first identified Entanglement as a peculiar quantum mechanics phenomenon, challenging the completeness of the theory. Because of the significance of the phenomenon of entanglement, the entanglement between a movable mirror and a cavity field is discussed in this article. Due to the importance of the subject, two types of design are considered for the analysis of the cavity caused by the moving mirror and for both, the analytical solution was performed and the governing equations were derived. In the first example, between two mirrors, one fixed and the other movable, a cavity field is found, in which case the interconnection between the rotating mirror and the two level atoms in the cavity field can be studied. In the second example, the first field is coupled to another cavity field and the effect of entanglement is studied on a mirror on which the atom is not located. The findings indicate that the greater entanglement and the wider efficient detuning area can be obtained with the increase in the coupling power of the coupled optomechanical device, so it is simpler and more feasible to realize and observe this kind of novel phenomenon in experiment.

Its properties like renewable, eco-friendly, sustainable biomaterial, and biocompatibility, biodegradable, cost-effectiveness, lightweight, and high mechanical strength, make it very useful in many fields. Nanocellulose is an ideal material to be used in the production of biopolymer composite, because of its properties such as low density, non-abrasiveness, combustibility, nontoxicity, and inexpensiveness. We can extract nanocellulose from both Bactria and plants. There are some reasons that bacterial cellulose is better than plant cellulose, which are given below. Bacterial nanocellulose has been used in various applications like medical products, food packaging, etc. This mini-review talks about the significant role of bacterial nanocellulose in the medical application including tissue engineering, drug delivery agents, wound healing, dental implant, bone tissue, and neural implants, cardiovascular implants, artificial cornea, etc. some studies have shown that some body`s cells such as endothelial, chondrocytes, and smooth muscle cells have good adhesion to BC.

      Abstract: Among the greatest varied and cross-cutting features of biomedical nanotechnology applications is the synthesis, design, and characterization of novel nanomaterials. New developments in synthetics and engineering make it possible to produce an extensive variety of nanoparticles (NPs) and biocompatible nanostructured materials widely used in efficient diagnosis, drug delivery, and therapeutic procedures or deprived of other chemical and/or surface modifications of biomolecules. Because of their physical and chemical properties, metal-based nanoparticles (MNPs), as well as quantum dots (QDs), magnetic NPs, metal NPs, and metal oxide NPs, have a tremendous amount of power for biomedical applications. Nanoparticles (NPs) have superior (chemical and physical) features that create an ideal for different usages. Metallic NPs' structural modifications result in various biological activities, leading to diverse development capacities for reactive oxygen species (ROS). With chemistry, size, surface area, and particle shape, the amount of ROS provided by metallic NPs are correlated. In cell biology, ROS has many functions. ROS generation is a critical component in the toxicity caused by metallic NP and cellular signaling in cell differentiation, proliferation, and death.
