Resonant Spin Amplification and Accumulation in MAPbI3 Single Crystals

Advanced 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

Advanced 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.

From Ancient Techniques to Modern Solutions: In Situ Synthesis of C‐S‐H for Sandstone Conservation

Advanced Science, EarlyView.
Herein, this work presents a paleo‐inspired approach to synthesizing and optimizing C‐S‐H‐based grouting mortars for conserving the sandstone of Beishan Grottoes, Dazu Rock Carvings, China. By achieving an optimal recipe compatible with natural sandstone, this work demonstrates the pivotal role of hydrogen bonding in the adhesion between C‐S‐H mortars ...

Lipid Droplet‐Organized MDM2‐Mediated P53 Degradation: A Metabolic Switch Governing Diet‐Driven Tumor Progression

Advanced Science, EarlyView.
Tumor‐associated TP53 inactivation correlates with lipid droplet (LD) accumulation. High‐fat diets drive Cyb5r3‐Myh9‐mediated p53 enrichment on LD surfaces, accelerating its degradation while upregulating LD‐promoting factor CD36 expression to establish a feed‐forward loop. LD suppression or dietary intervention restores p53 and inhibits tumorigenesis,
