    ABSTRACT: In this study, the authors report the fabrication of nasal delivery system, termed nasal insert, and was carried out with ionic and nonionic polymer(s). The data revealed that nonionic polymer has less water uptake and low mucoadhesion time in comparison to the ionic polymers. With ionic polymers, relaxation of entangled polymer from the gel was toward lesser extent, thereby providing sustained release during in vitro release. The SEM images show more compact nature of ionic polymer when compared with nonionic polymer. Histopathology and in vitro permeation study conducted using sheep nasal mucosa showed significantly higher drug permeation from nonionic polymer.

    ABSTRACT: A modified nanofibrous poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) nerve conduit has been used to evaluate its efficiency based on the promotion of peripheral nerve regeneration in rats. The authors used a gelatin-modified nanofibrous poly (3-hydroxybutyrate-co-3-hydroxyvalerate) nerve conduit to bridge a 30 mm long gap in the rat sciatic nerve. At four months after nerve conduit implantation, regenerated nerves were macroscopically observed and histologically assessed. In the nanofibrous graft, the rat sciatic nerve trunk had been reconstructed by restoration of nerve continuity and formation of myelinated nerve fiber. There were Schwann cells and glial cells in the regenerated nerves. These findings suggest that modified nanofibrous poly(3-hydroxybutyrate-co-3- hydroxyvalerate) nerve conduit is suitable for repair of long-segment sciatic nerve defects.

    ABSTRACT: Hydrogels were prepared from 2-hydroxy ethyl methacrylate and acrylamidoglycolic acid using N,N’-methylene bis acrylamide as a crosslinking agent in presence of potassium persulfate initiator. The average molecular mass between crosslinks (M c) and polymer-solvent interaction parameter of hydrogels were determined from equilibrium swelling values. Fourier transform infrared spectroscopy of hydrogels shows the confirmation of the formation of co-polymeric hydrogels. Scanning electron microscopy of hydrogels shows the porous network structure. Differential scanning calorimetry and X-ray diffraction were performed to understand the crystalline nature of hydrogel and drug after encapsulation in to hydrogels. In vitro release studies indicated the release of 5-Fluorouracil for more than 12 h.

    ABSTRACT: Polypyrrole (PPy)/ poly(pyrrole-co-acrylamide) (Poly(Py-co-AAm)/ nanocomposite was prepared by a simple and inexpensive in situ co-polymerization of pyrrole and acrylamide in presence of Fe3O4 nanoparticles. The nanocomposites were characterized by FTIR, SEM, XRD, TGA and conductivity measurements. The FTIR spectra ascertain the chemical interlinking of polypyrrole and copolymer with magnetite nanoparticles. The XRD revealed that crystallinity of the copolymer was increased with weight percentage of the magnetite nanoparticles. SEM analysis showed that the nanoparticles were well shaped and uniformly dispersed in the nanocomposites. Thermal stability and the electrical conductivity of the nanocomposite were higher than that of polypyrrole and the copolymer.

    ABSTRACT: A copolymer resin, p-chloroacetophenone oxime-furfuraldehyde (CAOFU), and a terpolymer resin, p-chloroacetophenone oxime-formaldehyde-benzoic acid (CAOFUBA), were synthesized in the presence of hydrochloric acid as catalyst. The structures of copolymer and terpolymer were established by FT-IR and 1H NMR techniques. Molecular weight and polydispersity index were determined by gel permeation chromatography. The thermal stability was evaluated by thermogravimetric analyses (TGA). Softening temperatures (Ts) of these polymers were obtained from differential scanning calorimetry (DSC). All the synthesized polymers have shown reasonably good antimicrobial activities.

    ABSTRACT: In this study, we report the enhanced osteoblast differentiation of mouse embryonic stem cell (mESC) on a novel polygalacturonic acid (PGA)/gelatin scaffold. The matrices of various PGA/geletin ratios were fabricated, biophysically characterized, and optimized for cell culture applications. Blended 2% PGA/gelatin scaffolds were highly porous and were robust with enhanced mechanical strength. Swelling studies showed they had high swelling capacity (six-fold higher than only gelatin scaffold) along with complete degradation in the presence of phosphate-buffered saline. Cytocompatibility of the matrices was evaluated using mouse fibroblast 3T3-L1 cell line showing normal spreading and proliferation as assessed by scanning electron microscopy (SEM) and MTT assay. Among different blends of PGA/gelatin, 2% PGA/gelatin (2PG) scaffold showed the optimum physical and biological compatibility for use in cell culture and differentiation of mESC, especially for osteoblast differentiation. The scaffold, as reported in this study, presents a promising tool for tissue engineering applications.

    ABSTRACT: An interfacial polymerization method for nylon 66 was adapted to produce nanostructured composites with nanohydroxyapatite (n-HA) via in situ polymerization. Nylon 66 was synthesized in n-HA slurry to increase homogeneity and biocompatibility. Synthesis powders was characterized by XRD, TEM, TGA, and FT-IR analysis. The results showed a uniform dispersion in composites, whereas needle-like, n-HA crystals dispersed in condensed polymer matrix. The samples were immersed in SBF for bioactivity tests in different periods, and results were monitored by SEM and EDX in terms of forming an apatite layer. The mechanical properties of the n-HA=nylon66 nanocomposites are discussed in terms of n-HA loading.

    ABSTRACT: Hyperbranched polyurea modified nanoclay was used for the preparation of vegetable oil modified sulfone epoxy nanocomposites at different loadings (1-5 wt%) for the first time. The bio-based nanocomposites were characterized by XRD, SEM, TEM and FTIR techniques. These nanocomposites showed an enhancement of thermal stability up to 48 °C as revealed by thermo-gravimetric analysis. The nanocomposites with 5 wt% of nanoclay exhibited more than 300 percent improvement in tensile strength, though the elongation at break decreases with the increase of nanoclay loading. Thus the studied nanocomposites possess better performance over the pristine system.

    ABSTRACT: This preliminary work reports the development of biodegradable films using blends of dehydrated castor oil epoxy (DCOE) with poly (methylmethacrylate) (PMMA) and poly(methacrylic acid) (PMAA). The biodegradability characteristics of the blends were investigated using degradation in phosphate buffer, activated sludge, and soil burial test measurements. The results revealed that the blends with higher content of DCOE underwent higher degradation as compared to the blends with lower DCOE content. Among the DCOE/PMMA and DCOE/PMAA blends, the latter were found to exhibit higher degradation, which was explained with the help of a suitable mechanism.

    ABSTRACT: Polyimides (PIs) are considered to be one of the most important engineering materials. The nano-particle of barium strontium titanate (BST) with formulation of Ba0.77Sr0.23 TiO3 was synthesized by the sol-gel method. In this process, different contents of BST suspensions in polyamic acid (PAA) solution were imidized by heat treatment to form PI=BST nanocomposites. Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), simultaneous thermal analysis (STA), scanning electron microscope (SEM), and transmission electron microscopy (TEM) were used to characterize the structure and properties of the obtained nanocomposites. It was found that the BST nanoparticles sized 32–40nm were dispersed homogeneously in the polyimide matrix without aggregation. The f potential of PI=BST 33 vol.% was decreased in contrast with that of the pure polyimide. The coefficient of thermal expansion (CTE) of PI=BST 33 vol.% was measured between 36�C and 600�C. CTEs comparison showed about 80% decrease in the CTE value of the nanocomposite in respect to the pure polyimide in a wider temperature range.

    ABSTRACT: The terpolymer resins have been prepared by polycondensation of vanillin (V) and chloro/bromo-substituted acetophenone (CA/BA) with furfural (FU) in the presence of 1 M HCl in 1:1:2 molar proportions. The characterization and structural elucidation of terpolymers were confirmed by FT-IR, pyrolysis GC-MS, and non-aqueous conductometric titration. Activation energy during curing process was determined by the Kissinger method, whereas thermal decomposition was determined by the Ozawa-Flynn-Wall method. Both terpolymer resins have shown excellent antimicrobial activity as compared to the standard ciprofloxacin and amphotericin-B drugs.

    ABSTRACT: Aluminium thin films on polyethylene terephthalate substrates prepared via thermal evaporation method and annealed under different temperatures have been investigated. High peak belonging to aluminium atoms is evident from energy dispersive X-ray spectra. From X-ray diffraction pattern, the polycrystalline nature of aluminium thin film is observed with (200) dominant peak at 2θ=44.52°. With increased annealing temperatures, the atomic force microscope shows increased surface roughness root-mean-square but sheet resistance and surface reflectance show reducing values. The effects of each characterization towards performance of thin film silicon solar cells are subsequently discussed.

    ABSTRACT: A series of novel alumina/titania hybrid materials was synthesized from aluminum isopropoxide and titanium-n-butoxide using a sol-gel process. Grey Lyocell fabrics were dyed, and the alumina/titania hybrid materials were combined with the dyed Lyocell fabrics through a dipping-dry-thermosol process. The structures of the alumina/titania hybrid materials were analyzed using FTIR, 27Al-NMR, and XRD and the bonding structures of the processed Lyocell fabrics were evaluated using SEM, EDS, and TGA analysis. The sheet evenness of the coated layer on the Lyocell fabrics was confirmed by SEM images, and the interaction of the hybrid materials with the Lyocell fabrics was verified. Moreover, weathering, electric conductivity, and air permeability analyses of the processed fabrics were conducted. Our data show that electric conductivity of the alumina/titania hybrid materials combined with Lyocell processed fabrics improved with increased concentration of aluminum isopropoxide in the reaction mixture. After modification with alumina/titania hybrid materials, the processed fabrics all had a light fastness level of approximately grade 4.

    ABSTRACT: Polyamide 6 (PA6) membranes were exposed to Ar plasma to produce peroxides on their surfaces, followed by grafting polymerization of methacrylic acid (MAA) introducing -COOH on surfaces. PA6 membranes immobilized with collagen I were obtained by coupling collagen to the MAA graft chains. The physicochemical properties were characterized by contact angle measurement, ATR-FTIR, XPS, and AFM. The results showed that the hydrophilicity of the surface improved after surface modification. The surface topography of the original and the modified PA 6 membranes showed an increase in roughness. Moreover, collagen immobilized onto PA 6 membranes showed enhanced growth in ROB culture tests.
