Design and Performance of a High‐Efficiency Inhibitor: Synergistic Effect of Modified Chitosan and Boron Nitride Nanosheets on Steel Protection

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Metal corrosion causes significant economic losses and safety hazards, underscoring the urgent need for effective, environmentally friendly corrosion inhibitors. In this study, an organic–inorganic composite inhibitor, chitosan–glucose–BN (CS–GL–BN) was developed to protect Q235 mild steel in a 3.5‐wt% NaCl solution.

Controlling Structures and Properties of NaCl‐Containing Alginate/Polyacrylamide Tough Hydrogels via a One‐Pot Process

Chemistry – A European Journal, EarlyView.
NaCl‐incorporated alginate/polyacrylamide tough hydrogels are prepared through a facile one‐pot strategy that enables direct ion incorporation during network formation. Compared with conventional soaking, this approach reduces diffusion‐limited ion gradients and provides a more spatially consistent ion distribution.

Synergistic Crystallinity Reduction and Lewis Acidic Promotion by PVDF‐Al(OH)3 for High Room‐Temperature Ionic Conductivity in PEO‐Based Composite Quasi‐Solid Electrolytes

EcoEnergy, EarlyView.
Through the synergistic effects of crystallinity reduction and Lewis acidic promotion enabled by PVDF‐Al(OH)3, a PEO‐based composite quasi‐solid electrolyte has been developed, achieving both a high Li+ transfer number and superior ionic conductivity. It endows lithium metal batteries with excellent cycling stability at room temperature, even without ...

Effect of Sequential and Combined Space‐Based Stressors on Perovskite Solar Cell Stability

EcoEnergy, EarlyView.
A correlation between loss in performance and mobile ion concentration has been established by sequential stressing of perovskite solar cells under Low Earth Orbit conditions with exposure to protons, light, and thermal cycling. It is shown that the loss in performance increases when ion concentration increases and vice versa.

Gradient p‐p Orbital Hybridization in Bismuth‐Doped Crystalline Carbon Nitride for Dual‐Functional Carbon‐to‐Carbon Valorization

EcoEnergy, EarlyView.
Schematic illustration comparing the charge transfer dynamics and catalytic reaction over the (left) pristine carbon nitride and (right) Bi‐doped carbon nitride photocatalysts. In the pristine system, random charge diffusion and rapid recombination limit catalytic efficiency. In contrast, the Bi‐doped system establishes a robust internal electric field
