Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Electrostatic Superlattices Beyond 1:1 Stoichiometry

Advanced Functional Materials, EarlyView.
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

Numerical Analysis and Control Study on Surrounding Rock Deformation of Deep Soft Rock Roadway [PDF]

E3S Web of Conferences, 2021
Aiming at the problem of large-scale deformation of the track and alleys in the East Second Mining Area, the numerical analysis method is used to analyze the stress and deformation law of the roadway. The results show that the critical depth of the roadway deformation is 800m, the shear stress of the deep roadway is about 8.7MPa in the left and right ...

Domain Engineering and Anisotropic Domain‐Wall Photovoltaic Effects in Ferroelectric SnS

Advanced Functional Materials, EarlyView.
The bulk photovoltaic effect at domain walls in the in‐plane ferroelectric 2D semiconductor SnS is investigated using periodic domain structures. Unlike conventional oxide ferroelectrics, domain walls of SnS do not contribute to photocurrent generation perpendicular to the domain walls.

Evolution Mechanism of Deformation and Failure of Surrounding Rock during Excavation and Unloading of the High‐Stress Rock Mass [PDF]

Advances in Civil Engineering, 2020
To deeply analyze the failure evolution of surrounding rock during excavation‐induced unloading of the high‐stress rock mass, a multistage failure model was established based on revealed failure patterns. The critical conditions for wing cracks were determined. The slab crack buckling analysis was carried out. The true‐triaxial rockburst testing system

Freeze‐Thaw Engineered Dual Conductivity Polymeric Binder Stabilizes Large‐Volume‐Change Lithium–Ion Battery Anodes

Advanced Functional Materials, EarlyView.
This work developed an all‐aqueous freeze‐thaw strategy to create a dual‐conductive PVA/P3KBT binder for high volume‐change lithium–ion battery anodes. The resulting binder system strengthens the electrode structure, supports ion and electron transport, and accommodates repeated volume changes, reducing cracking and improving long‐term cycling ...
