Methionine Residues in Exoproteins and Their Recycling by Methionine Sulfoxide Reductase AB Serve as an Antioxidant Strategy in Bacillus cereus

Frontiers in Microbiology, 2017
During aerobic respiratory growth, Bacillus cereus is exposed to continuously reactive oxidant, produced by partially reduced forms of molecular oxygen, known as reactive oxygen species (ROS).

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Optically Active Sulfoxides from 2(5H)-Furanone and Monoterpene Alcohols: Synthesis, Structure, and Antibacterial Activity

Учёные записки Казанского университета: Серия Естественные науки
A series of optically active 5(S)-(l-bornyloxy)- and 5(S)-(l-menthyloxy)-2(5H)-furanones with an arylthio group at the C(4) position of the γ-lactone ring was synthesized and studied for its oxidation reactions with various reagents. Novel 2(5H)-furanone

Support‐Controlled Reaction Pathways via Dynamic Sulfur‐Mediated Interfaces for Selective Urea Electrolysis

Advanced Functional Materials, EarlyView.
Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

Demonstrating Vibrational Current Generation With a Self‐Assembled Bioelectret

Advanced Functional Materials, EarlyView.
Vacuum‐deposited films of the plant‐derived molecule, Baicalein, form a self‐assembled bioelectret exhibiting spontaneous orientation polarization and a giant surface potential. The films induce alternating current during the vibration of a movable electrode without charging treatments. Hydrocarbon protection enhances the air stability of the Baicalein

Water Adsorption‐Induced Color Sensor: Insight Into the Sensing Mechanism and Interfacial Engineering for Improved Responsiveness

Advanced Functional Materials, EarlyView.
We report a unique color‐sensing phenomenon of a TiO2/SbSI:Sb2S3 device utilizing X‐ray absorption. Based on the revealed penetration and adsorption of water onto TiO2, we successfully improved the color response speed and sensitivity by incorporating a hydrophilic polymer interlayer, thereby opening up opportunities for photodetection applications ...

Monitoring of Methionine Sulfoxide Content and Methionine Sulfoxide Reductase Activity [PDF]

, 2017
The sulfur-containing amino acid methionine (Met) plays critical roles in protein synthesis, methylation, and sulfur metabolism. Both in its free form and in the form of an amino acid residue, it can be oxidized to the R and S diastereomers of methionine sulfoxide (MetO).

Giant Electrostriction in Halide Perovskites Revisited With Double‐Modulation Interferometry

Advanced Functional Materials, EarlyView.
A giant electrostrictive effect in lead halide perovskites had been reported previously. This work uses sensitive interferometry to measure the electromechanical response of various halide perovskite samples. The results reveal no intrinsic electrostrictive compression. Instead, the materials expand primarily under an applied electric field as a result
