Tailored D‐π Conjugation Boosts Piezocatalytic CO2 Reduction in a Platinum(II)‐Acetylide Framework

Advanced Science, EarlyView.
The highly conjugated metalII‐acetylide framework demonstrates efficient ultrasound‐driven conversion of CO2 to CO. The piezoelectric field generated by ultrasound facilitates electron transfer from the tetraphenylene π‐column to the MII‐bis(acetylide) moiety, enabling CO2 activation. Compared to PdII‐ and NiII‐based analogues, the stronger d–π orbital

Effects of nonlinear elasticity and electromechanical coupling on pressure coefficient of the light emission in group-III nitride quantum structures

Journal of Physics: Conference Series, 2008
We present theoretical studies of the effects of nonlinear elasticity and electromechanical coupling on the pressure coefficients of the light emission, dEE/dPext, in GaN/AlN and In0.2Ga0.8N/GaN superlattices with compressively strained quantum wells. We show that effect of the nonlinear elasticity, manifesting itself in pressure dependence of elastic ...

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses
