Thermally Induced Creep and Viscoelastic Behavior of Copper Micropillar Arrays

Advanced Science, EarlyView.
Copper micropillar arrays are fabricated by electrodeposition within through‐glass‐via, and their thermally induced time‐dependent deformation is quantified. Nanoindentation creep, EBSD, and TEM reveal a heat‐treatment‐driven transition between grain‐boundary‐mediated deformation and dislocation‐dominated creep, while Kelvin modeling captures ...

Single‐Crystal PZT‐Driven Organic Piezo‐Phototronic Adaptive Transistors Toward Advanced Spatiotemporal Visual Computing

Advanced Science, EarlyView.
Here, we propose a single‐crystal PZT‐based piezo‐phototronic organic adaptive memory transistor (OAMT), achieving a record memory window capacity factor (γ) of 0.87 at a low SS of 200 mV/decade via efficient multi‐field control. The device achieves a high recognition accuracy ∼ 90% in neuromorphic simulations, demonstrates robust fault tolerance under

Study on subsurface damage of WC-10Co-4Cr coating in planar grinding of cup sand wheels

Jixie qiangdu
The subsurface damage depth of grinding WC-10Co-4Cr coating with a cup wheel was investigated in an effort to address the issue that the subsurface damage will cause the coating's performance to deteriorate.

Measurements of mixed-mode crack surface displacements and comparison with theory [PDF]

A theoretical and an experimental technique is used to determine crack surface displacements under mixed-mode conditions. Crack surface displacements proved to be quite useful in mode 1 fracture analysis in that they are directly related to strain energy

ZMAT1 Promotes Osteoclastogenesis Through TRIM46 Mediated YAP1 Degradation and Inhibits Osteoblastogenesis

Advanced Science, EarlyView.
Zmat1 deficiency mitigates pathological bone loss by impairing osteoclastogenesis and promoting osteoblastogenesis. Mechanistically, in osteoclasts, Zmat1 loss relieves transcriptional repression of the E3 ligase TRIM46, promoting YAP1 degradation and inhibiting osteoclastogenic genes.

Bioinspired Microphase‐Engineered Binders for Silicon Anodes

Advanced Science, EarlyView.
Inspired by the tough exoskeleton of Phloeodes diabolicus, a bio‐based binder featuring LRA–click chemistry and hierarchical crosslinking forms well‐defined microphase‐separated structures that enable robust silicon anodes. This system promotes the formation of a LiF–rich, ultrathin SEI (∼17 nm) with high modulus and ionic conductivity, ensuring long ...

Mechanism of Solid Solution‐Driven Texture Induced by Ag Doping in YBCO Superconductor

Advanced Science, EarlyView.
Ag‐doped YBCO with a designed concentration gradient is produced by dual‐material co‐extrusion and freeze‐drying. During annealing, Ag+ ions diffuse into Y123, substituting for Cu(1) and inducing c‐axis relaxation. This leads to the formation of [001]‐oriented YBCAO, creating a coherent interface that templates the textured growth of Y123. Consequently,
