A Quest for the Mechanism of Ultrahigh Resolution SEM Imaging

Advanced Science, EarlyView.
Using Monte Carlo simulations with explicit definitions of SE1 and SE2 align with a cascade secondary electron production model, this work shows that the 3D nanostructure modulated SE2 emission enhances other than to reduce topographical contrast via a “miniature Faraday cup” effect.

Universal Solvent Escape Strategies for Efficient Curing of Hydrogen‐Bond‐Rich 3D Printing Inks

Advanced Science, EarlyView.
This study developed a new 3D printing method for hydrogen‐bonded polymers by combining solvent replacement, nanoparticles, and optimized printing paths. This allows fast, precise scaffold fabrication. The scaffolds can be easily customized and release therapeutic agents slowly through protonation, enabling personalized bone, blood vessel, and nerve ...

Durable Thin‐Film Porous Transport Electrodes for High Current Density PEM Water Electrolysis

Advanced Science, EarlyView.
Water electrolysis using porous transport electrodes with sputter‐deposited, ionomer‐free thin films of rutile IrO2 catalyst suppresses Ir dissolution by >10x over other forms of IrOx. The rutile IrO2 catalyst prepared by this readily scalable electrode synthesis method provides stable cell operation at 3 A cm−2 while using low Ir loading (0.4 mg Ir cm−

Transforming Grain‐Boundary Brittle Precipitates to Ductility Pathways in Complex Concentrated Alloy

Advanced Science, EarlyView.
By engineering graded BCC/L12 interfaces, brittle precipitates in a complex concentrated alloy enable sequential deformation, realizing gigapascal strength with >20% elongation to solve the strength‐ductility trade‐off. ABSTRACT Conventional wisdom holds that hard grain‐boundary (GB) precipitates embrittle structural alloys by acting as crack ...

Hierarchical Strain‐Modified Medium‐Entropy Carbide Ceramics Exhibit Exceptional Ablation Resistance up to 2400°C

Advanced Science, EarlyView.
A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.

Fe/N‐Doped Carbon with Nearly Ordered Mesopores and Tunable Particle Sizes as Model Catalysts for Quantitative Evaluation of Electrocatalytic Active Sites

Advanced Science, EarlyView.
This study is dedicated to the design and synthesis of MOF‐derived mesoporous Fe/N‐doped carbons as model catalysts, aiming to quantitatively evaluate the utilization of active sites in the ORR. Through modulation followed by pyrolysis, we successfully prepare size‐tunable Fe/MNC‐x with doped iron atoms and mesoporous structures. The smaller Fe/MNC‐250

Addressing Oxygen Embrittlement in Additively Manufactured Titanium via Cu‐Mediated Interstitial Site Engineering

Advanced Science, EarlyView.
A novel “Cu‐mediated interstitial site engineering” strategy is introduced to thermodynamically stabilize hexagonal oxygen (hex‐O) configurations in oxygen‐containing titanium alloys. The hex‐O configuration activates multiple slip systems and enhances dislocation pinning via long‐range repulsion.
