Nucleophilic Covalent Ligands Enable Simultaneous Surface Reconstruction and Passivation of Colloidal InSb Quantum Dots for Stable Short‐Wave Infrared Photodetectors

open access: yesAngewandte Chemie, EarlyView.
A simultaneous surface reconstruction and passivation strategy is designed for indium antimonide (InSb) colloidal quantum dots (CQDs) using sulfur‐based nucleophilic covalent ligands. This leads to stable CQD inks and 1450 nm‐operating InSb CQD photodetectors with 28% external quantum efficiency and 300 h operating lifetime. Abstract Indium antimonide (

Protective and Collision‐Sensitive Gel‐Skin: Visco‐Elastomeric Polyvinyl Chloride Gel Rapidly Detects Robot Collision by Breaking Electrical Charge Accumulation Stability

open access: yesAdvanced Intelligent Systems, EarlyView.
For safe human–robot collaboration (HRC), a protective and collision‐sensitive robot skin is proposed. The developed robot skin, named Gel‐Skin, is composed of polyvinyl chloride (PVC) gel, which is a functional material with impact absorption capability and tunable piezoresistive characteristics based on electrical charge‐accumulation.
