Abstract:We reported the synthesis of ink-perovskite/Polyaniline composite electrode material for the separation of sodium chloride solution. These electrode materials are prepared by in situ polymerization process of aniline in the presence of perovskite ceramic material with carbon catalyst surface. This material is having the highest conductivity as a cathode material, environmentally benign and low cost material. The structure and morphological properties of prepared ternary composites are characterized by Fourier transform infrared, X-ray diffraction, SEM and TGA. The electrochemical properties are also investigated using four probe method and cyclicvoltametry method. Electrochemical measurement shows that the conductivity of ternary composites is 128 Scm −1 . Resulting composites are promising cathode material for low power consuming electrolysis process of sodium chloride solution.
This review presents a comprehensive introduction to recent advances in the field of blends of the natural and synthetic polymers as new material for biodegradable membranes. These materials and several blends have attracted industrial attention because they exhibit improvements in properties which are required in membrane technology. In the current review, the structure, preparation coating method and properties of the blends of natural and man-made polymer are discussed. We focus on the applications of blend materials for membrane technology like fuel cells, membrane electrolytes and ultrafiltration membranes for water treatment. From the literature, it is found that the most common natural polymers: collagen, chitosan, chitin, cellulose, starch and poly(lactic acid) are used as components of blends with man-made polymers. We have also studied the introduction of nano-fibrous and nano-particles to improve the mechanical properties of these membranes.
The aim of current work to develop and evaluate sustained release mucoadhesive (SRM) microspheres of Repaglinide using emulsification solvent evaporation technique. Effects of formulation variables i.e. polymer concentration and phase volume ratio on particle size, % mucoadhesion and drug release were investigated in this study. Scanning electron microscopy of microspheres with maximum drug content (Formulation CH1:8) demonstrated smooth surface spherical particles with mean diameter of 64.78 ± 3.26 μm. The mean Particle size, % drug loading and mucoadhesion were found to vary by changing the formulation variables. Microspheres size was significantly increased as increasing the polymer concentration in the aqueous phase while size of microspheres decrease as increase in volume of continuous phase. Decrease in size of microspheres leads to decrease in mucoadhesion time, % drug loading and faster the drug release. It can be concluded that the present mucoadhesive microspheres can be an ideal system to deliver the Repaglinide in sustained release manner for management of Type II Diabetes Mellitus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
