Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Advanced Electronic Materials, EarlyView.Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Angewandte Chemie, EarlyView.This study reports a new hole‐transporting material (WD03) designed via molecular engineering to regulate defect passivation and energy‐level alignment in perovskite solar cells (PSCs). The propeller‐shaped structure ensures balanced charge transport and film quality. Consequently, WD03‐based devices deliver a high open‐circuit voltage of 1.194 V under

Low‐Power Control Of Resistance Switching Transitions in First‐Order Memristors
Advanced Electronic Materials, EarlyView.Joule losses are a serious concern in modern integrated circuit design. In this regard, minimizing the energy necessary for programming memristors should be handled with care. This manuscript presents an optimal control framework, allowing to derive energy‐efficient programming voltage protocols for resistance switching devices. Following this approach,
