Although most monomers can polymerize through different propagation pathways, polymerization-initiating systems that switch from one mode to another are rare. In this study, we demonstrate enamine-based organic electron donors (OEDs) constitute the first able initiate either free-radical or anionic polymerization under simple, mild, and safe conditions. While direct electron-transfer reduction ...

Transient states maintained by energy dissipation are an essential feature of dynamic systems where structures and functions regulated fluxes matter through chemical reaction networks. Perfected in biology, chemically fueled dissipative networks incorporating nanoscale components allow the unique properties nanomaterials to be bestowed with spatiotemporal adaptability responsiveness. We report ...

europium (eu) doped zno microsphere based nano-sheets were synthesized through hydrothermal method. effects of different concentrations of europium on structural and optical properties of zno nano-sheets were investigated in detail. prepared un-doped and eu-doped zno samples were characterized using x-ray diffraction (xrd), energy dispersive x-ray spectroscopy (edx), scanning electron microscop...

Submitochondrial particles from mung bean mitochondria (Phaseolus aureus) are able to catalyze an energy-linked reduced nicotinamide adenine dinucleotide-nicotinamide adenine dinucleotide phosphate transhydrogenase reaction supported by ATP or by aerobically generated high energy intermediates. The energy transfer pathway appears to differ from that utilized for oxidative phosphorylation.Mung b...

Electron transfer between the title compounds and their radical cations, which were generated by photoinduced electron transfer from the sulfides to excited 2,4,6-triphenylpyrylium cations, was investigated by time-resolved measurements of chemically induced dynamic nuclear polarization (CIDNP) in acetonitrile. The strongly negative activation entropies provide evidence for an associative-disso...
