Different measures for characterizing the motion of molecules along a temperature gradient [PDF]
Phys. Rev. E 99, 062108 (2019), 2019 We study the motion of a Brownian particle in a medium with inhomogeneous temperature. In the overdamped regime of low Reynolds numbers, the probability distribution function (PDF) of the particle is obtained from the van Kampen diffusion equation [J. Phys. Chem. Solids {\bf 49}, 673 (1988)].

Microfluidic pump driven by anisotropic phoresis [PDF]
Phys. Rev. Applied 11, 054004 (2019), 2018 Fluid flow along microchannels can be induced by keeping opposite walls at different temperatures, and placing elongated tilted pillars inside the channel. The driving force for this fluid motion arises from the anisotropic thermophoretic effect of the elongated pillars that generates a force parallel to the walls, and perpendicular to the temperature ...

Fast and Versatile Thermo-osmotic Flows with a Pinch of Salt [PDF]
Nanoscale 14, 626 (2022), 2020 Thermo-osmotic flows - flows generated in micro and nanofluidic systems by thermal gradients - could provide an alternative approach to harvest waste heat. However, such use would require massive thermo-osmotic flows, which are up to now only predicted for special and expensive materials.

Step size of the rotary proton motor in single FoF1-ATP synthase from a thermoalkaliphilic bacterium by DCO-ALEX FRET [PDF]
, 2012 Thermophilic enzymes can operate at higher temperatures but show reduced activities at room temperature. They are in general more stable during preparation and, accordingly, are considered to be more rigid in structure. Crystallization is often easier compared to proteins from bacteria growing at ambient temperatures, especially for membrane proteins ...

Quantifying the Role of the Surfactant and the Thermophoretic Force in Plasmonic Nano-Optical Trapping [PDF]
, 2020 Plasmonic nano-tweezers use intense electric field gradients to generate optical forces able to trap nano-objects in liquids. However, part of the incident light is absorbed into the metal, and a supplementary thermophoretic force acting on the nano-object arises from the resulting temperature gradient.
