Thermal Diffusion of Nucleotides
The Journal of Physical Chemistry B, 2012We investigate the thermal diffusion behavior of aqueous solutions of nucleotides using an infrared thermal diffusion forced Rayleigh scattering (IR-TDFRS) setup. In this work we study 5 nucleotides: cyclic nucleotides adenosine and guanosine monophosphate, 5'-adenosine and 5'-cytidine monophosphate, and also adenosine diphosphate in water.

Continuous monitoring of cerebral blood flow (CBF) has been an area under research to observe immediate changes in blood flow under a wide variety of circumstances. Recently, however, continuous monitoring of blood flow in the trauma cases has provided prognostic and therapeutic help in the management of these patients.

Thermal diffusivity imaging with the thermal lens microscope
Applied Optics, 2011A coaxial thermal lens microscope was used to generate images based on both the absorbance and thermal diffusivity of histological samples. A pump beam was modulated at frequencies ranging from 50 kHz to 5 MHz using an acousto-optic modulator. The pump and a CW probe beam were combined with a dichroic mirror, directed into an inverted microscope, and ...

Thermal Diffusion and Convective Stability
The Physics of Fluids, 1972The stability of a two-component fluid layer subjected to a temperature gradient has been studied, and the associated thermal diffusion separation has been found to exert a large influence even when the separations are small. The most unexpected and perhaps important result is that an instability has been found which can give rise to convection ...

Physical Review Letters, 2005
The Ludwig-Soret effect or thermal diffusion, which refers to the separation of liquid mixtures in a temperature gradient, is governed by a nonlinear, partial differential equation in space and time. It is shown here that the solution to the nonlinear differential equation for a binary mixture predicts the existence of shock waves completely analogous ...

Thermal Diffusivity Measurements of Thermographite
International Journal of Thermophysics, 2004This paper presents results of measurements of a graphite proposed to serve as a thermophysical property reference or standard reference material. The reported measurements contribute to a program launched in 1999 by Anter Corp. with the objective to provide a replacement for the NIST thermal property reference material RM AXM-5Q graphite whose ...

Thermal diffusion of Boussinesq solitons
Physical Review E, 2007We consider the problem of the soliton dynamics in the presence of an external noisy force for the Boussinesq type equations. A set of ordinary differential equations (ODEs) of the relevant coordinates of the system is derived. We show that for the improved Boussinesq (IBq) equation the set of ODEs has limiting cases leading to a set of ODEs which can ...
