Natural convection heat transfer in hemisphere. [PDF]
Journal of Nuclear Science and Technology, 1988 Natural convection in a hemisphere was studied with bottom surface heated and hemispherical surface cooled. Heat transfer and flow visualization experiments were performed. The range of Rayleigh number and Prandtl number were 9 × 106 1 × 109), the effect of the hot thermal plumes was con...

Advanced Functional Materials, EarlyView.Designing stable Ru nanoparticle catalyst remains a critical challenge in electrochemical applications. Here, a strategy is presented to stabilize Ru catalysts by leveraging Ce‐doped ZrO2 supports (ZrCeO2‐x), which enhance catalyst durability and activity through electronic metal‐support interactions and stabilized oxygen vacancies.

A Universal Way to Manipulate Droplet via Light‐Fueled Thermocapillary Convection
Advanced Functional Materials, EarlyView.A non‐contact light‐induced droplet manipulation strategy fueled by mid‐infrared (MIR) light irradiation is introduced. No additional additives and/or complex substrate are required. Here, thermocapillary convection, directly generated by temperature gradient at outer surface of droplet via localized surface heating, plays a key role to propel the ...
