Probing the Challenge of P‐Type Semiconductors in Long‐Chain VOC Detection: 3D Micro‐Flower Zinc Cobaltate Heterojunction Sensors

open access: yesAdvanced Science, EarlyView.
Fe@WO3/ZnCo2O4 n‐p heterojunction sensor exhibits excellent room‐temperature sensing toward tetradecane, with a low detection limit of 78.4 ppb and short recovery time. The good performance is attributed to synergistic effects from heterojunctions, heteroatom doping, oxygen vacancies, high‐energy facets, and theoretical validations.

Resonant Spin Amplification and Accumulation in MAPbI3 Single Crystals

open access: yesAdvanced Science, EarlyView.
Carrier spin dynamics are studied in a 20 µm thin MAPbI3 perovskite single crystal using time‐resolved Kerr ellipticity at cryogenic temperatures. Long spin relaxation (30 ns) and dephasing (21 ns) enable spin accumulation. Spin accumulation effects are discussed in detail along with carrier‐nuclear spin interactions.

Aerial Track‐Guided Autonomous Soft Ring Robot

open access: yesAdvanced Science, EarlyView.
Controlling motion paths in soft active material‐based robots is challenging due to their inherently high degrees of freedom. Inspired by aerial trams, a new class of autonomous, track‐guided soft robots composed of twisted liquid crystal elastomer rings are reported.

Amyloid Forming Human Lysozyme Intermediates are Stabilized by Non‐Native Amide‐π Interactions

open access: yesAdvanced Science, EarlyView.
Mutational variants of human lysozyme cause fatal systemic amyloidosis by depositing kilograms of protein in the viscera of patients. Central to this process is a partially unfolded protein intermediate state that initiates aggregation into amyloid fibrils.
