Abstract: Polyacrylamide-b-poly(methacrylic acid) was prepared on the surface of Au electrode (Au/PAM/PMAA) for Pb2+ ion electrochemical sensing via metal-free visible-light-induced atom transfer radical polymerization, which was very simple, convenient, and environmentally friendly. Au/PAM/PMAA was carefully examined… read more here.

DOI: 10.1021/acsami.9b00456
Abstract: We introduce a method for the direct imprinting of GaAs substrates using wet-chemical stamping. The predefined patterns on the stamps etch the GaAs substrates via metal-assisted chemical etching. This is a resist-free method in which… read more here.

DOI: 10.1055/s-0037-1609480
Abstract: A novel, one-pot reaction for the synthesis of isoxazolines and isoxazoles is developed via a cascade process under metal-free conditions. The approach involves the formation of intramolecular C–N and C–O bonds and intermolecular C–C bonds… read more here.
