Radiative Thermal Management for Extreme Environments: Mechanisms and Design Strategies

open access: yesAdvanced Materials, EarlyView.
In this review, we discuss the fundamental mechanisms of radiative cooling and solar heating, material and structural design strategies, hybrid approaches integrating additional heat transfer pathways, and durability‐oriented designs addressing environmental stresses.

A study of the influence of free convection on coagulation process

open access: yes, 1999
It was assumed [1, 2] that gravity affects the coagulation process in two ways: free convection, which is hard to be avoided on the ground and sedimentation, which can be greatly reduced by the density-matching method.

Programmable Carrier‐Free All‐Enzyme Beads for Modular Continuous‐Flow Biocatalysis

open access: yesAdvanced Materials, EarlyView.
Genetically encoded enzyme building blocks self‐assemble into monodisperse, carrier‐free protein beads via a droplet‐based formulation strategy. These programmable catalytic particles enable modular continuous‐flow biocatalysis, from single‐enzyme reactions to multi‐enzyme cascades and bead–bead coupled reactor systems.

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.

Thresholds for Atmospheric Convection in Amazonian Rainforests

open access: yesGeophysical Research Letters, 2019
The Amazon rainforest is known as the “Green Ocean” for its maritime‐like convection and cloud microphysics during the wet season. Although previous studies suggest the dominant thermodynamic processes involved in deep convection may differ between land ...

A GEOMETRICAL CONFIGURATION AND ITS EFFECT ON THE PERFORMANCE OF AN ELECTROCHEMICAL CELL UNDER FREE CONVECTION [PDF]

open access: yesJournal of Engineering Science and Technology, 2018
The effect of positioning or location of the cathode electrode with respect to the surface margin of the electrodeposition electrolyte solution under free convection was numerically studied. The importance of such study arises from the fact that there is
