Environmentally friendly preparation of nanoparticles for organic photovoltaics

Environmentally-friendly preparation of water-dispersible magnetite nanoparticles.

Water-dispersible Fe(3)O(4) nanoparticles have been prepared by a simple solution method, in which the particle size (3-11 nm) can be tuned by simply adjusting the reaction temperature and time; the formation mechanism of Fe(3)O(4) nanoparticles is proposed and their low cytotoxicity has also been proved.

Preparation and Application of a Novel Environmentally Friendly Organic Seed Coating for Rice

Chitosan was modified with sodium hydroxide and polymerized in water with plant growth regulators, microfertilizer and other additives to give a novel environmentally friendly seed coating agent for rice. The results showed the seed coating agent has obvious biological effect through the germination test, bacteriostasis test, toxicological security test and field experiment. Compared with the t...

Perylenediimide functionalized bridged-siloxane nanoparticles for bulk heterojunction organic photovoltaics.

Perylenediimide functionalized bridged siloxane nanoparticles were prepared by direct hydrolysis and condensation of a perylenediimide silane precursor in the presence of a catalytic amount of tetraethoxysilane (TEOS). The sizes of the particles were controlled by adjusting organotrialkoxysilane, base, and TEOS concentrations. Using this modified Stöber method, we were able to incorporate a hig...

Recyclable nanostructured catalytic systems in modern environmentally friendly organic synthesis.

Modern chemical synthesis makes heavy use of different types of catalytic systems: homogeneous, heterogeneous and nano-sized. The latter--nano-sized catalysts--have given rise in the 21st century to a rapidly developing area of research encompassing several prospects and opportunities for new technologies. Catalytic reactions ensure high regio- and stereoselectivity of chemical transformations,...
