Deciphering Short‐Range Order in 2D Transition Metal Dichalcogenides: From Origin to Multi‐Scale Property Modulation

open access: yesAdvanced Science, EarlyView.
Short‐range order in 2D transition metal dichalcogenides is revealed as a new design paradigm. Driven by chemical affinity and atomic size, it governs properties across scales. Weak ordering tunes site‐resolved magnetism and d‐band centers, while strong ordering eliminates gap states to open band gaps.

The Dynamic Response Analysis of Elastic Slider-Crank Mechanisms.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1992
A numerical analysis method is developed to investigate the dynamic response of elastic slider-crank mechanism systems. The equation of motion was obtained by means of the finite-element technique, including the nonlinear effects of a centrifugal force and an axial force.

High‐Performance Prevascularized SHED‐Laden rGO@Hydrogel Achieves Optimized Diabetic Bone Defect Repair

open access: yesAdvanced Science, EarlyView.
A high‐performance 3D scaffold integrating rGO and SHEDs is developed to overcome impaired healing in diabetic bone defects. By driving extracellular matrix remodeling, rGO creates a pro‐angiogenic niche that significantly accelerates in vitro vascular network formation.

V2CTx MXene as a Sacrificial Promoter for NiFe Catalyst for Anion Exchange Membrane Electrolyzers

open access: yesAdvanced Science, EarlyView.
These findings demonstrate that V2CTx functions beyond passive conductive support as an active electronic participant whose structural legacy sustains durable performance even after vanadium leaching in Anion Exchange Membrane (AEM) Electrolysers. ABSTRACT Nickel‐iron layered double hydroxides (NiFe‐LDH) show excellent activity, their poor conductivity

Dielectric‐Confinement‐Induced in‐Plane Photoelectric Anisotropy in Isotropic Quasi‐1D γ‐GaS Nanoribbon

open access: yesAdvanced Science, EarlyView.
We investigate the geometry‐governed optoelectronic anisotropy arising from dielectric confinement in quasi‐1D γ‐GaS nanoribbons with intrinsically isotropic atomic structures. Dielectric mismatch between the nanoribbon and its surroundings leads to a general polarization‐dependent photoresponse during near‐field scattering.

Boosting Photocatalytic Overall Water Splitting Activity of Phosphorene Through Five‐Coordinate Passivation Enabled by Carbene Addition

open access: yesAngewandte Chemie, EarlyView.
We report selective five‐coordinate passivation of phosphorene via P═C double bonds using a facile one‐step photochemical reaction via carbene addition. The ambient stability of functionalized phosphorene has been substantially improved compared to the pristine phosphorene.
