Light‐Activated Micromotors in Air Propelled by Thermal Convection

Advanced Materials, EarlyView.
Near‐infrared‐driven micromotors in air can overcome gravity and generate convective motion by a light‐induced thermal mechanism driven by a temperature gradient in the air caused by the interaction of the gold nanoparticles present on the surface of ZnO and NIR irradiation.

Numerical Research on Cooling Performance of Magnetic Nanofluids in a Natural Convection Transformer

Chemical Engineering Transactions
The transformer is extensively cooled internally by natural convection, which can handle most electrical load conditions and ensure that the maximum internal temperature (hot spot temperature) does not exceed the allowable value.

Review of Thin Lithium Metal Battery Anode Fabrication – Microstructure – Electrochemistry Relations

Advanced Materials, EarlyView.
Thin, lightweight lithium‐metal anodes are pivotal for practical high‐energy batteries. This review surveys processing routes that convert diverse Li precursors, e.g., ingots, melts, solutions, and vapor, into Li‐rich foils with controlled thickness, areal density, and tailored functionality.

One‐Step Coordinated Multi‐Kinetic 4D Printing of Human Vascularized Cardiac Tissues with Selective Fast‐Shrinking Capillaries

Advanced Materials, EarlyView.
This study presents a novel 4D bioprinting technique for fabricating cardiac tissues with complex microvasculature. Unlike traditional 3D printing, it enables capillary‐scale structure formation via selective post‐printing shrinkage. This approach overcomes resolution limits of printing cell‐laden hydrogels, allowing the creation of functional ...

Entropy generation analysis for vertical flat and corrugated surface by natural convection and radiation at constant heat flux

Case Studies in Thermal Engineering
Previous literature has explained heat transfer by natural convection, radiation and the effect of entropy generation separately. This study focused on the entropy generation of heat transfer by natural convection and radiation instantaneously from ...

Magnetic Field‐Driven Spin State Transformation in Promoting the Catalytic Activity of Doped Single‐Atom for Hydrogen Evolution Reaction

Advanced Materials, EarlyView.
A ferromagnetic RuSAs/Ni2P@Fe3O4 material is designed via a synergistic strategy of single‐atom doping and magnetic field‐driven spin‐state transformation. This strategy introduces new Ru single‐atom active sites for the hydrogen evolution reaction and facilitates the transition of Fe3+ (3d t2g) low‐spin electrons to a high‐spin state (3d eg ...
