Soret feedback in thermal diffusion of suspensions

, 1998
We have theoretically studied the interaction of a light beam with liquids containing absorbing nanoparticles. We have shown that the Soret effect ensures a feedback that essentially limits heat insertion into the system and the change in its temperature:

The Rayleigh–Benard problem in extremely confined geometries with and without the Soret effect [PDF]

, 2007
We examine the linear stability of a liquid layer heated from below (the classical Rayleigh–Benard problem) but laterally confined between four vertical rigid and adiabatic boundaries. The main feature of the present study is that the height of the layer

Photocatalytic Hydrogen Evolution From Self‐Assembled Stacks of Pd–TCPP and Pt–TCPP

Small, EarlyView.
ABSTRACT The present work demonstrates that surfactant‐free precipitation of Pd– and Pt–TCPP in MeOH/H2O yields well‐defined supramolecular architectures (µm‐long nanorods) whose photocatalytic function tracks their metal‐dependent photophysics and stacking.

Self-oscillatory convection caused by the Soret effect

, 2002
A new kind of finite-amplitude convective oscillations in binary mixtures caused by the Soret effect is predicted. Such oscillations can be observed in colloidal solutions of nanoparticles whose diffusion coefficient is about two orders of magnitude ...

Numerical Analysis of Entropy Generation of MHD Casson Fluid Flow Through an Inclined Plate with Soret Effect

East European Journal of Physics
In this present study, entropy generation for an unsteady MHD Casson fluid flow through an oscillating inclined plate is investigated. Here, along with reaction by chemical and thermal radiation incorporation of Soret effect is also analysed.

Wavelength dependence of the efficiency of singlet oxygen generation upon photoexcitation of photosensitizers

EPJ Web of Conferences, 2017
The dependence of the efficiency of singlet oxygen (1Δg) generation upon excitation of photosensitizer at different wavelength was observed for several derivatives of palladium porphyrin in carbon tetrachloride.

Development of a MEMS channel device for hydrogen gas separation based on the Soret effect

Journal of Thermal Science and Technology, 2014
Energy sources independent of fossil fuels or atomic power are of great importance to achieve a sustainable society from the viewpoint of environmental conservation and benefits. Hydrogen is considered as one of the main candidates for new sources.

Training and validation of an automated algorithm to differentiate no and minimal diabetic retinopathy from more severe stages in wide‐field images

Acta Ophthalmologica, EarlyView.
Abstract Purpose Diabetic retinopathy (DR) is a leading cause of blindness in the working‐age population. Screening is essential to identify and treat sight‐threatening stages prior to irreversible visual loss. This study aimed to train and validate an automated algorithm to identify no or minimal DR, potentially saving resources for specialist ...

Brownian Motion and Thermophoretic Diffusion Effects on Micropolar Type Nanofluid Flow with Soret and Dufour Impacts over an Inclined Sheet: Keller-Box Simulations

Energies, 2019
The principal objective of the current study is to analyze the Brownian motion and thermophoretic impacts on micropolar nanofluid flow over a nonlinear inclined stretching sheet taking into account the Soret and Dufour effects.

Afamelanotide improves quality of life and light tolerance in Austrian erythropoietic protoporphyria patients

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background Erythropoietic protoporphyria (EPP) is a rare genetic disorder characterized by severe phototoxic reactions that occur within minutes of light exposure. In clinical studies, afamelanotide has been shown to prolong pain‐free sun exposure, improve quality of life, and reduce the frequency and severity of phototoxic reactions ...
