In this paper, natural convection heat transfer over a vertical plate in a Darcy porous medium saturated with a nanofluid subject to heat generation/absorption was theoretically studied. The governing partial differential equations were transformed to a set of ordinary differential equations using similarity transformations and solved using finite difference method. The influence of parametric ...

Epigenetic regulation is based on specific molecular interactions between epigenetic reader, writer and eraser molecules and chromatin. Binding parameters of these interactions such as binding affinities, stoichiometries and thermodynamics are essential for the understanding of the establishment and maintenance of epigenetic networks. The MicroScale Thermophoresis (MST) is a rapid and precise m...

This article reviews optical manipulation coupled with photochemical/photothermal responses of nanometer sized materials including molecular systems, polymers, and inorganic nanoparticles. After the introduction, section 2 overviews trapping systems early-stage studies, such as polymer chains, micelles, aggregates in solution at room temperatures. Then, conformation control macromolecule assemb...

We demonstrate, theoretically and experimentally, self-trapping of optical beams in nanoparticle suspensions by virtue of thermophoresis. We use light to control the local concentration of nanoparticles, and increase their density at the center of the optical beam, thereby increasing the effective refractive index in the beam vicinity, causing the beam to self-trap.

MicroScale Thermophoresis (MST) follows the movement of fluorescent-labelled biomolecules with different sizes along a temperature gradient.

A gold nanoshell-functionalized polymer multilayer nanorocket performs self-propulsion upon the irradiation with NIR light in the absence of chemical fuel. Theoretical simulations reveal that the NIR light-triggered self-thermophoresis drives the propulsion of the nanorocket. The nanorocket also displays -efficient NIR light-triggered propulsion in -biofluids and thus holds considerable promise...

The effect of thermophoresis on the impaction particles a cylinder is investigated for different particle sizes, conductivities, temperature gradients and Reynolds numbers between 100 1600. This first such study performed using Direct Numerical Simulations (DNS), where all temporal spatial scales fluid are resolved. Pencil Code, high-order finite difference code with an overset-grid method prec...

Abstract Spatial proton gradients create energy in biological systems and are likely a driving force for prebiotic systems. Due to the fast diffusion of protons, they however difficult as steady state, unless driven by other non-equilibria such thermal gradients. Here, we quantitatively predict heat-flux formation pH case simple acid-base reaction system. To this end, (i) establish theoretical ...
