To inform the public.
Description:
Vitamins B2, B1, C, tea polyphenols, and natural surfactants, which function both as reducing and capping agents, provide simple, one-pot, green synthetic methods to bulk quantities of nanomaterials. Synthesis of noble nanostructures via microwave (MW)-assisted spontaneous reduction of noble metal salts using sugars and glutathione, cross-linking of poly (vinyl alcohol) (PVA) with metallic; bimetallic systems; and SWNT, MWNT, and C-60; and formation of biodegradable carboxymethyl cellulose composite films with noble nanometals will be presented. Alignment of carbon nanotubes in CMC is possible using MW approach which enables the shape-controlled bulk synthesis of Ag and Fe nanorods in poly (ethylene glycol). MW hydrothermal approach to magnetic nanoferrites and micro-pine structured oxides will be described. The eco-friendly generation of magnetic nanoparticles, nanocomposites with renewable polymers and their applications in catalysis and environment will be highlighted.
