In the present investigation, at first, the surface of titanium dioxide (TiO2) nanoparticles was modified with γ-aminopropyltriethoxy silane as a coupling agent.
A novel compound constructed from polyoxometalate (H3PW12O40, PW12) and poly(amidoamine) (PA) was prepared at room temperature in an aqueous solution by an impregnation method.
The main aim of this research was to study the electrochemical behavior of novel optically active poly(amide-imide)s (PAIs).
Hydantoin and thiohydantoin derivatives 4(a-e) were synthesized from reactions of
benzil and benzil derivatives 3(a-e) with urea and thiourea. 5,5-dimethylhydantoin
This paper describes the facile and selective oxidation of sulfides 1 and thiols 3 to their corresponding sulfoxides 2 and disulfides 4 with potas
