Cigarette Smoke‐Induced Alveolar Macrophage Senescence via GEM/SIRT3‐Mediated Mitochondrial Dysfunction

Advanced Science, EarlyView.
Cigarette smoke accelerates the aging of immune cells in the lung. By combining human single‐cell sequencing, cell culture, and mouse models, the authors show that the protein GEM drives mitochondrial damage and senescence in alveolar macrophages by suppressing SIRT3.

Combustion of lean flammable mixtures in an intense radiation field.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1988
A combustion process showing a slow temperature rise was realized in an intense radiation field by burning a lean combustible mixture in a cylindrical combustion chamber lined with a refractory in which a permeable plate was placed at the upstream and downstream ends, respectively.

Sustainable Materials Design With Multi‐Modal Artificial Intelligence

Advanced Science, EarlyView.
Critical mineral scarcity, high embodied carbon, and persistent pollution from materials processing intensify the need for sustainable materials design. This review frames the problem as multi‐objective optimization under heterogeneous, high‐dimensional evidence and highlights multi‐modal AI as an enabling pathway.

Experimental investigations into high-altitude relight of a gas turbine

, 2008
This thesis describes experiments to investigate high-altitude relight of a lean direct injection (LDI) combustor. The features that make LDI technology less polluting in terms of NOx compared to conventional combustors are expected to impede relight ...

Thermochemical Micro‐Explosion for Prompt Thrombolysis via Proximal Injection of Liquid Alkali Metal

Advanced Science, EarlyView.
We report a micro‐explosive thermochemical thrombolysis (METCT) therapy via injectable liquid alkali metal encapsulated in dimethyl silicone (LAM@oil). METCT enables prompt and safe vascular recanalization within 90 s. Critically, the LAM@oil system demonstrates significantly higher thrombolytic efficacy compared to clinically available thrombolytic ...

Highly Efficient and Environmentally Stable Radiative Cooling Fabric: Integrating Photoluminescence and Hierarchical Core–Shell Fibers

Advanced Science, EarlyView.
A scalable radiative cooling fabric engineered with a multi‐layer assembly core–shell structure and integrated photoluminescent materials is reported. The fabric exhibits remarkable environmental stability, including UV resistance, mechanical durability, hydrophobicity, stain resistance, thermal stability, and flame retardancy, demonstrating its ...
