Electrochemiluminescence Discloses Active Intermediates in Oxygen Evolution Reactions of Metal–Organic Framework

Advanced Science, EarlyView.
Electrochemiluminescence microscopy is designed to monitor the important hydrogen peroxide intermediate on metal–organic framework during oxygen evolution reaction (OER) catalyzing. It creates a powerful and convenient analytical method to understand the detailed elemental steps, reveal the electrocatalytic activity of nanoparticle or spatial ...

Trypstatin as a Novel TMPRSS2 Inhibitor with Broad‐Spectrum Efficacy against Corona and Influenza Viruses

Advanced Science, EarlyView.
Trypstatin, a 61‐amino acid Kunitz‐type protease inhibitor derived from human Bikunin, potently inhibits TMPRSS2 and related proteases. It blocks spike‐ and hemagglutinin‐mediated entry of multiple respiratory viruses in vitro reduces SARS‐CoV‐2 replication in human airway cultures, and lowers viral load and symptoms in infected hamsters, demonstrating

ALKBH5‐Mediated M6A Demethylation of G3BP1 Attenuates Ferroptosis Via Cytoplasmic Retention of YBX1/p53 in Diabetic Myocardial Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
ALKBH5 promoted G3BP1 expression via m⁶A methylation at sites 142/173. G3BP1 interacts with YBX1 and p53, reducing their nuclear translocation and decreasing p53‐mediated SLC7A11 repression. This inhibites cardiomyocyte ferroptosis and mitigates myocardial damage during diabetic ischemia‐reperfusion injury.

Strain‐Induced Polarization Rotation in Freestanding Ferroelectric Oxide Membranes

Advanced Electronic Materials, EarlyView.
Combining piezoresponse force microscopy, Raman spectroscopy, and scanning transmission electron microscopy, the ferroelectric polarization of a Pb(Zr,Ti)O3 membrane is mapped in a fold‐like structure. A polarization rotation from out‐of‐plane to in‐plane is evidenced, occurring at a low strain threshold (≈0.2%), and is suggested to be entirely driven ...

Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

Advanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

Recognizing Visibility Graphs of Polygons with Holes and Internal-External Visibility Graphs of Polygons

, 2018
Visibility graph of a polygon corresponds to its internal diagonals and boundary edges. For each vertex on the boundary of the polygon, we have a vertex in this graph and if two vertices of the polygon see each other there is an edge between their ...

A Novel Quantification Method for High Voltage Structural Evolution in Sodium and Lithium Layered Oxides

Advanced Energy Materials, EarlyView.
High‐voltage cycling of layered alkali transition metal oxides in Li‐ and Na‐ion cells increases energy density but diminishes lifetime. A novel XRD‐analysis method, centered on the stacking factor “z”, is developed to quantify the stacking fractions in the OP hybrid structure.

Metal‐Organic Open‐Framework Molecular Magnet Based on Vanadium Hexacyanoferrate Prussian Blue Analogs as Cathode Material for Advanced Potassium Ion Aqueous Battery

Advanced Energy and Sustainability Research, EarlyView.
An aqueous potassium‐ion battery using vanadium hexacyanoferrate (VHCF) as the cathode and graphite as the anode is presented. During charge/discharge, K+ ions shuttle between electrodes through the electrolyte, enabling energy storage. The VHCF material demonstrates high capacity (≈121 mAh g−1), fast kinetics, and eco‐friendliness, making it a ...
