Amino-terminated polydimethylsiloxane modified porphyrin for efficiently biphasic photosynthesis of H2O2

Nano Research
Hydrogen peroxide (H2O2) attracts widespread attention as a clean and sustainable oxidant. Nevertheless, porphyrin-based photocatalysts generally exhibit low H2O2 concentration in aqueous systems because the generated H2O2 does not accumulate effectively

New Photoresponses of Phycomyces [PDF]

Plant Physiology, 1973
The influence of light on asexual fruiting and mycelial growth of Phycomyces blakesleeanus Burgeff was studied by means of fruiting body counts and size measurements in cultures on solid media under varied incubation conditions. Five types of photoresponses were shown by ATCC Strain 8743a: (a) photoinduction of giant sporangiophores; (b) interference ...

A photoresponsive glycosidase mimic

Chemical Communications, 2014
Azobenzene-3,3'-dicarboxylic acid exists in photoisomerizable (E) and (Z)-forms. Deprotonation of the carboxylic acid groups from the (E)-form occurs simultaneously, whereas in the (Z)-form it occurs in a stepwise fashion. The mono anionic form of the (Z)-isomer acts as a glycosidase mimic that proceeds through a general acid-general base catalytic ...

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance
