Electrodes modified with lipid membranes to study quinone oxidoreductases

, 2009
Quinone oxidoreductases are a class of membrane enzymes that catalyse the oxidation or reduction of membrane-bound quinols/quinones. The conversion of quinone/quinol by these enzymes is difficult to study because of the hydrophobic nature of the enzymes ...

Hydrogen‐Bond Enabled Phosphite Based Intrinsic Flame‐Retardant Solid‐Solid Phase Change Materials Using Catalyst/Solvent‐Free Multi‐Component Reaction for Battery Thermal Management

Advanced Science, EarlyView.
The phosphite group endows intrinsic flame retardancy, while the P = O bond enhances intermolecular interactions to realize solid‐solid phase transition. Battery thermal management tests show the materials extend the safe working time of lithium‐ion batteries by 200%. Cone calorimeter tests indicate a 14s delay in ignition time, and reductions of 37.6%,

NMR analysis of the estrogen o-quinone to estrogen o-quinone methide equilibrium

, 2016
: Electrophilic metabolites of estrogen, namely estrogen o-quinones, are genotoxic and have been associated with breast and other human cancers. The formation of estrogen o-quinones from catechol estrogens can also lead to o-quinone methides via ...

Formation of Hydrogen Sulfide in Wine: Interactions between Copper and Sulfur Dioxide

Molecules, 2016
The combined synergistic effects of copper (Cu2+) and sulfur dioxide (SO2) on the formation of hydrogen sulfide (H2S) in Verdelho and Shiraz wine samples post-bottling was studied over a 12-month period.

Self-Adaptable Quinone-Quinol Exchange Mechanism of Photosystem II

, 2018
The step of plastoquinone (PQ) reduction to plastoquinol (PQH(2)) can regulate the photoreaction rate of photosystem II (PSII). To experimentally unravel the PQ-PQH(2) exchange mechanism of PSII, we investigate the reaction kinetics of plant PSII ...

Thermal‐Ionic Coupling in Transpiration‐Inspired Janus Nanofiber Membranes: Synergistic Dry‐Wet Interface Engineering for Solar‐Driven Electricity Generation

Advanced Science, EarlyView.
A transpiration‐inspired Janus nanofiber membrane creates a persistent dry‐wet interface that couples localized solar heating with hydration‐induced ion regulation. The asymmetric architecture sustains directional water and ion transport, suppresses salt accumulation, and enables simultaneous seawater evaporation and stable electricity generation ...
