ABSTRACT Functional polymer/AgNPs nanocomposites have been prepared. Silver nanoparticles (NPs) were synthesized to which polyacrylamide, PAAm, was covalently bound. PAAm via a RAFT reaction and carried thiol carboxylic acid end groups. Thiol used bind the polymer metal surface carboxyl for further reactions. The AgNPs in post‐crosslinking with separately poly(butyl acrylate‐ co ‐methyl methacrylate)/polyglycidyl methacrylate core/shell latex bearing epoxy functional Dynamic mechanical...

Abstract Eco-friendly leather processes based on the usage of natural products have become a potentially attractive issue for industry during last few decades. Synthetic protective chemicals like bactericides used in most soaking process are known as hazardous substances and cause tannery effluents with high concentrations Chemical Oxygen Demand (COD). In present study, effect tannic acid microorganisms, skin, wool effluent were investigated order to demonstrate applicability instead...

Boscia coriacea Graells (BC), Grewia erythraea (Schweinf.) Chiov. (GE), Ochradenus baccatus Delile(OB), and Orthosiphon pallidus Royle ex Benth. (OP) are medicinal plants used in Djibouti. They were evaluated to determine their total phenolic content (TPC), flavonoid (TFC), phytochemical profile using HPLC-MS/MS. Additionally, antioxidant capacity was assessed through five various methods. Enzymatic activities also measured, focusing on acetylcholinesterase (AChE), butyrylcholinesterase...
