Synthesis, Characterization, and Biomedical Applications of a Silver Nanoparticle-Coated Chitosan–Fucoidan–Polymer Nanocomposite Loaded with Persea americana Leaf Extract
Abstract: Consuming a natural composite of Persea americana (Avocado) leaf extract and a chitosan and fucoidan form a biodegradable biopolymer matrix–polymer nanocomposite with biomedical applications, this study explored a potential therapeutic method. GC–MS and UV spectroscopy were used to describe the aqueous leaf extract, which was verified by phytochemical screening to contain flavonoids, tannins, phenols, terpenoids, and alkaloids. The chitosan–fucoidan biodegradable polymer matrix served as a biocompatible stabilizing and encapsulating carrier …

A Novel Approach for Extraction of Polyphenols
Abstract: Polyphenols are class of compounds which are found in fruits, vegetables, walnuts, olives, tea leaves and many more. Polyphenols are antioxidant phyto-chemicals that prevent or neutralize the damaging effects of free radicals. They are secondary metabolites of plants and are generally involved in defence against ultra-violet radiation or aggression against pathogens. Polyphenols are various alcoholic compounds containing two or more benzene rings that each has at least one hydroxyl group …

Depolymerization of Polypropylene: A Systematic Review
Abstract: AbstractPolypropylene have become an indispensable ingredient of human life and most widely used thermoplastic in commodity applications. Polymerization of propylene is carried out by using Ziegler-Natta or Metallocene catalysts, which results in high molecular weights and crystalline polypropylene which are not required for several applications. Reduction in molecular weight of polypropylene in conventional reactors is uneconomical and complicated. Therefore to overcome this problem researchers and technologists proposed a post reactor …

Modification of Acrylonitrile-Methylacrylate Copolymer by Gamma Irradiation
Abstract: AbstractRadiative degradation of acrylonitrile-methylacrylate (AM) copolymer has been investigated by electron spin resonance (ESR) and infrared (IR) spectroscopy. The ESR spectrum observed for AM copolymer irradiated to a dose of 12 Mrad is a triplet with an intensity ratio of 1:3:1. The ESR spectrum is simulated by total-curve-fitting method and component spectra are generated. Magnetic parameters of component spectra are evaluated. Component triplet spectrum with magnetic parameters ni=3, mi=1 is …
