Programmable Multifunctional Bistable Structures for Energy Transfer and Dissipation

Advanced Science, EarlyView.
Utilizing the energy conversion characteristics of asymmetric bistable beams, this study develops a programmable multifunctional system composed of multiple bistable beams for energy transfer and dissipation. The high energy density enables the system to demonstrate potential in transient scenarios such as target delivery and shock absorption ...

Decoding the Cardiac Immune Microenvironment and Fibroblast Crosstalk in Radiotherapy Combined with Immunotherapy‐Induced Cardiac Fibrosis Based on Single‐Cell Transcriptomic Analysis

Advanced Science, EarlyView.
This study highlights that radioimmunotherapy drives crosstalk between fibroblasts and immune cells (especially macrophages) in the cardiac microenvironment, with IL‐6 as the key mediator, and tocilizumab alleviates cardiac fibrosis by targeting this interplay.

Critical Limitations in Cryogenic Laser Cooling of Solids: Symmetry‐Related Fluorescence Trapping and Condensation‐Induced Parasitic Heating

Advanced Science, EarlyView.
This study uncovers two overlooked bottlenecks in cryogenic laser cooling of solids: symmetry‐driven fluorescence trapping and water vapor condensation. We demonstrate that breaking sample symmetry enhances fluorescence escape, while condensation dominates parasitic heating below 135 K.

Compliant Polymeric Sheet‐Based Heat Exchangers

Advanced Science, EarlyView.
This work presents flexible, transparent, and deployable polymer heat exchangers that achieve a heat transfer capacity per cost up to 4x higher than the state of the art, surpassing both metal and other polymer counterparts. The tube‐on‐tube design enables efficient heat transfer without flow occlusion, while the lightweight, corrosion‐resistant, and ...
