A Universal Way to Manipulate Droplet via Light‐Fueled Thermocapillary Convection

Advanced Functional Materials, Volume 36, Issue 2, 5 January 2026.
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 ...

Symmetry Breaking in Chemical Systems: Engineering Complexity Through Self‐Organization and Marangoni Flows

Advanced Science, Volume 13, Issue 5, 27 January 2026.
We show that solutal Marangoni flows in thin films climbing the outer surfaces of hydrophilic obstacles break circular Belousov‐Zhabotinsky waves into striking flower‐like patterns. Evaporation‐driven surface‐tension gradients, coupled with gravity, trigger the instability; above a threshold, petal number scales linearly with obstacle diameter ...

The Barrel of Ilmenau: A large-scale convection experiment to study dust devil-like flow structures.

Meteorologische Zeitschrift, 2021
We present an experimental facility for the validation of numerical simulations on atmospheric dust devils in a controlled laboratory experiment. Dust devils are atmospheric air vortices with a vertical axis, and are formed by intense solar radiation and

Computational Fluid Dynamic Analysis of Fluid Motion and Volumetric Gas–Liquid Mass Transfer in Agitated Platelet Concentrate Storage

Biotechnology Journal, Volume 21, Issue 1, January 2026.
Graphical Abstract and Lay Summary Platelets (PLTs) are small blood cells that play a vital role in stopping bleeding. After donation, they are stored in special bags, but their quality decreases over time. One reason for this decline is the mechanical stress they experience during collection, processing, and storage.

Exploring the Effects of Reduced Gravitational Field Impacts on Convective Heat Transfer: A Comprehensive Review

Heat Transfer, Volume 55, Issue 1, Page 764-774, January 2026.
ABSTRACT This review explores the impact of gravitational instability on convective heat transfer, integrating existing research results and theoretical models. Gravitational instability is vital in promoting or hindering convective actions in different systems, such as atmospheric events, ocean currents, and industrial processes.

Wall slip effects in Rayleigh–Bénard convection of viscoplastic materials

, 2023
International audiencePurpose According to the research, viscoplastic fluids are sensitive to slipping. The purpose of this study is to determine whether slip affects the Rayleigh–Bénard convection of viscoplastic fluids in cavities and, if so, under ...

Moist convection and radiative cooling: Dynamical response and scaling

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 775, January 2026 Part B.
The mechanism that sets the updraught velocities in deep convective clouds is studied here using cloud‐resolving model simulations in radiative–convective equilibrium. We show that, for simulations with vastly different rates of radiative cooling and surface temperatures, the buoyancy in clouds remains remarkably constant (histogram shown here).
