Multiphase Actuation of AC Electrothermal Micropump
Micromachines, 2023 Electrothermal micropumps apply an AC electric field to a conductive fluid within the range of 10 kHz–1 MHz to generate fluid flow. In this frequency range, coulombic forces dominate fluid interactions over opposing dielectric forces, resulting in high ...

Comment on “Can Charge Transfer Across C─H···O Hydrogen Bonds Stabilize Oil Droplets in Water?”
Angewandte Chemie, EarlyView.Nanoscale oil droplets in water are kinetically stable and charged, with a pH dependent electrophoretic mobility. Although the source of this charge is agreed to arise from water, 2 main hypotheses remain: OH− adsorption or electronic charge density displaced via hydrogen bonds. Molecular surface specific experiments are reviewed, that all point to the

Advanced Functional Materials, EarlyView.A cooperative and competitive interrelationship between alcohol oxidation (AOR) and water oxidation (OER) was observed on a typical anode catalyst of Ni2P. In situ Raman spectroscopy and electrochemical analyses revealed a specific complementary mechanism between them, in which OER and AOR critically contribute to the activity and stability of anodic ...
