Effects of the Cattaneo–Christov flux model on thermally radiative flow of tetra hybrid nanofluid with surface tension gradient

Case Studies in Thermal Engineering
The importance of thermal radiation and Stefan blowing on the boundary layer flow of tetra hybrid nanofluid flow across a disk are examined in the present work employing the Cattaneo-Christov flux model.

Molecular Extraction and Release of an Ionic Liquid Microdroplet With Dynamic Tunability Under Optical Trapping

ChemPhysChem, Volume 27, Issue 11, 15 June 2026.
We produce a single microdroplet by inducing local phase separation of a temperature‐responsive ionic liquid aqueous solution under optical trapping conditions. As the droplet grows, molecules in the surrounding solution are extracted to the droplet. Upon droplet shrinkage, these molecules are released from the droplet. The molecular release process is

Study on the Instability of Two-Phase Flow in the Heat-Absorbing Tube of Trough Solar Collector

International Journal of Photoenergy, 2017
The Marangoni effect and Rayleigh-Benard effect in the two-phase region of solar trough heat-absorbing tube are simulated by FTM (front tracking method). Considering the Marangoni effect alone, although surface tension gradient and surface tension affect

Turning Electrode Orientation into a Design Parameter: Gravity‐Driven Convection for Coupling Electrochemical and Enzymatic Reactions

ChemElectroChem, Volume 13, Issue 11, 3 June 2026.
Electrochemically induced density gradients are harnessed to drive gravity‐dependent convection at partially fouled electrodes. By controlling electrode orientation and surface heterogeneity, mass transport is enhanced without external stirring. This enables coupling of electrochemical reactions with enzyme catalysis on insulating domains, exemplified ...

Characterization of Marangoni Forced Convection in Casson Nanoliquid Flow with Joule Heating and Irreversibility

Entropy, 2020
The Marangoni forced convective inclined magnetohydrodynamic flow is examined. Marangoni forced convection depends on the differences in surface pressure computed by magnetic field, temperature, and concentration gradient.

Marangoni Flow Before Carlo Marangoni

Annalen der Physik, Volume 538, Issue 6, June 2026.
ABSTRACT In fluid dynamics, particularly in research on soft matter, it is well known that surface tension gradients drive fluid flow, a phenomenon known as Marangoni flow. The effect is named after Carlo Marangoni, who described it in 1865 as part of his doctoral thesis on droplets and liquid films. While Marangoni's contribution is rightly recognized,
