InfoMat, EarlyView.A multi‐defect‐engineered ZnO/GO flat‐band heterojunction enables a high‐dynamic‐range, low‐power optoelectronic synapse through enhanced photoresponse and reduced dark current. The device achieves a record 74.9 dB dynamic range and ultralow energy consumption of 23 fJ per spike at 1 mV.

Topological Engineering of High‐Order Exceptional Points Through Transformation Optics
Laser &Photonics Reviews, EarlyView.A novel framework leveraging transformation optics is introduced for engineering high‐order exceptional points (EPs) in nanophotonic systems. By linking these spectral singularities to physically accessible parameters, this approach enables the design of complex EPs, including third and fourth‐order EPs in coupled nanowire systems.

Effect of Variations in the Ring Thickness on the Dynamic Performance of the Bimetal Gears
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This study used a six‐degrees‐of‐freedom dynamic model to analyze the dynamic response of bimetal spur gears. Aluminum alloy forms the core of the bimetal gears, and a uniform‐thickness steel ring surrounds the teeth. Gear mesh stiffness of bimetal gears and the transmission error have been assessed using a numerical approach based on finite ...
