Mechanisms of pitting induced by containing Ce inclusions in X100 pipeline steel

Journal of Materials Research and Technology
Rare earth cerium (Ce) can reduce the pitting susceptibility and occurrence probability of X100 pipeline steel in a simulated marine environment by altering the characteristics and quantity of inclusions.

Cumulative‐Stress‐Resilient Microelectromechanical Switches for Extreme Environment Applications

Advanced Electronic Materials, EarlyView.
A microelectromechanical switch combines a thermomechanically stable suspended structure with radiation‐tolerant materials to preserve operation under cumulative shock (2900 g), vibration (2000 Hz), gamma irradiation (1 Mrad), extreme temperatures (4–450 K), and proton irradiation (100 MeV, 1012 p/cm2).

Fluxional Monomers Remodel Crystallinity at Low Loadings in Diketopyrrolopyrrole Co‐Thienothiophene Conjugated Polymers

Angewandte Chemie, EarlyView.
Bullvalene is a fluxional molecule capable of adopting numerous conformations spontaneously; just like a Rubik's Cube. In this paper, we explore the incorporation of bullvalene into the backbone of a highly rigid conjugated polymer semiconductor and observe that the inherent fluxionality reduces average crystallite size.

Characterizing Biopolymer Electrolytes in Zinc–Air Batteries: Challenges, Best Practices, and a Robust Workflow Guiding Future Research Paths

Advanced Energy Materials, EarlyView.
Bio‐based gel polymer electrolytes promise sustainable, mechanically adaptable zinc–air batteries, yet their progress is constrained by inconsistent characterization. This review critically links formulation, structure, interfaces, and cell performance, identifies methodological gaps under alkaline operating conditions, and proposes application ...

Engineering Polar Nanoregions in COFs via Controlled Symmetry Breaking Toward Piezocatalysis

Angewandte Chemie, EarlyView.
Polar nanoregions (PNRs) are engineered within covalent organic frameworks via asymmetric grafting of highly polar polyfluoroalkyl chains, which enables controlled symmetry breaking. These randomly oriented artificial PNRs dynamically respond to mechanical stimuli and impart relaxation behavior to the COFs (TFB‐TAPT‐FA).

MXene‐Derived Highly Oriented TiN Enables Ta3N5 Photoanodes for Transmission‐Mode Bias‐Free Solar Water Splitting

Advanced Energy Materials, EarlyView.
This work reports 2D MXene‐derived TiN thin films with (111)‐preferred orientation for transparent Ta3N5 photoanodes, demonstrating effective electron transfer behavior. All‐nitride electron‐collection architecture based on MXene‐derived TiN and n‐GaN resolves a long‐standing materials bottleneck between photocarrier transport and light transmission in

Suppressing Cathode Corrosion Induced by Impurity Cations in Alkaline Water Electrolyzers

Angewandte Chemie, EarlyView.
Impurity Fe species in electrolyte accelerate cathodic corrosion in alkaline electrolyzers by promoting peroxide formation. A strongly Lewis acidic CeOx protection layer stabilizes interfacial electronic structure via Fe−CeOx interactions, scavenges reactive oxygen species, and suppresses Fe accumulation, enabling stable Ni cathodes under universal ...
