Electrochromic properties of monosubstituted benzylboronic acid viologen [PDF]

open access: yesMATEC Web of Conferences, 2023
Synthesis of monosubstituted benzyl boronic acid viologen (mBBV) has been achieved. The boronic acid group in mBBV can form boronic ester bonds with the hydroxyl groups in polyvinyl alcohol (PVA), resulting in an all-in-one electrochromic gel.

A novel curvature‐correction technique insensitive to process variations

open access: yesElectronics Letters, 2023
This paper proposes a novel curvature‐correction technique insensitive to process variations, which can be used in not only the bandgap reference (BGR) circuit but also the Zener reference circuit. By using two BJT transistors to form a differential pair

Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc1

open access: yesFEBS Open Bio, EarlyView.
The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...
