Thermophoresis and Its Thermal Parameters for Aerosol Collection
The particle collection effi ciency of a prototype environmental tobacco smoke (ETS) sampler based on the use of thermophoresis is determined by optimizing the operational voltage that determines its thermal gradient. This sampler’s heating element was made of three sets of thermophoretic (TP) wires 25μm in diameter suspended across a channel cut in a printed circuit board and mounted with coll...
متن کاملBiotechnological applications of thermophoresis
Measuring parameters such as stability and con-formation of biomolecules, especially of nucleicacids, is important in the field of biology, medicaldiagnostics and biotechnology. We present athermophoretic method to analyse the conformationand thermal stability of nucleic acids. It relies on thedirected movement of molecules in a temperaturegradient that depends on su...
متن کاملThermophoresis of charged colloidal particles.
Thermally induced particle flow in a charged colloidal suspension is studied in a fluid-mechanical approach. The force density acting on the charged boundary layer is derived in detail. From Stokes' equation with no-slip boundary conditions at the particle surface, we obtain the particle drift velocity and the thermophoretic transport coefficients. The results are discussed in view of previous ...
متن کاملThermophoresis of Axially Symmetric Bodies
Thermophoresis of axially symmetric bodies is investigated to first order in the Knudsen-mimber, Kn. The study is made in the limit where the typical length of the immersed body is small compared to the mean free path. It is shown that in this case, in contrast to what is the case for spherical bodies, the arising thermal force on the body is not in general antiparallel to the temperature gradi...
متن کاملThermophoresis and Thermal Diffusion
Motivation: It turns out that a simple nonequilibrium environment created by a temperature gradient can be used to monitor the reaction kinetics of large proteins with small substrate molecules. This is probably caused by a change in the hydration layer of the protein which is influenced by subtle conformations changes induced by the binding substrate molecule. The underlying effect is thermoph...
