Advanced Science, EarlyView.Interlayer sliding in the RuO2Zn2F2 bilayer induces ferroelectricity and enables reversible valley polarization switching. The electric dipole and valley‐resolved band edges are intimately coupled, revealing sliding ferroelectricity as a powerful mechanism for electrical control of valley degrees of freedom in 2D materials.

Microwatt Volatile Optical Bistability via Nanomechanical Nonlinearity
Advanced Science, 2023 Metastable optically controlled devices (optical flip‐flops) are needed in data storage, signal processing, and displays. Although nonvolatile memory relying on phase transitions in chalcogenide glasses has been widely used for optical data storage ...

Nonsecular terms in optical bistability
, 2012 We investigate the influence of the nonsecular terms on the optical bistability in a photonic-crystal single-atom laser. The nonsecular terms result in a significant reduction of the bistability threshold.

Bioinspired Morphology‐Decoupled Soft Gripper with Enhanced Bidirectional Grasping Capability
Advanced Science, EarlyView.Inspired by biological predation, a novel gripper decouples cross‐modal grasping via dual morphological configurations. Synergistically integrating hybrid rigid and soft coupled fingers with a metamaterial palm, the system performs active compliant grasping for static objects and passive cage capture for dynamic targets.

Force Bistability in Adhesion Switch [PDF]
Biophysical Journal, 2016 The lateral junctions of epithelial cells must display mechanical stability to form barriers, but also significant plasticity to allow for reorganization during development and repair. In this issue, Biswas et al. (1) extend the use of fluid supported-lipid bilayers (SLBs) to reconstitute function of the key adhesion molecule that initiates lateral ...

Optimization of SWCNT‐FET Biosensors by Aptamer Engineering and Toehold‐Mediated Strand Displacement
Advanced Science, EarlyView.Aptamer‐based single‐walled carbon nanotube (SWCNT) field‐effect transistor (FET) biosensors are developed for label‐free, real‐time biomarker detection. Truncated DNA aptamers enhance sensitivity through improved conformational switching. A toehold‐mediated strand displacement (TMSD) strategy optimizes functionalization and simplifies fabrication. The
