Hydrodynamic methods based on the injection of a coolant gas into the boundary layer—the intense heating zone—through porous surfaces are widely used to protect the head part of flight vehicles and surfaces of power plants against high-enthalpy and chemically aggressive gas flows.

Thermal activation and viscosity
Physica B: Condensed Matter, 2000Creep behavior in superconductors is used to show how viscosity can affect thermally activated processes. In the case of a number of lead alloys the creep rate in the normal state is substantially less than in the superconducting state, in the temperature range where barriers control the creep process.

The temperature dependence of the kinetic friction between a highly oriented pyrolytic graphite surface and a silicon nitride probe tip has been evaluated through atomic force microscopy measurements performed under an ultra-high vacuum environment over the temperature range 140–750 K.

Abstract The behaviour of particulate and granular materials are particularly affected by thermal activation. Hence single particle activation is discussed along with the phenomenon of superparamagnetism and blocking. Because particulate and granular materials never contain a single particle size, a detailed discussion of the effects of ...

The temperature-dependence of the viscosity η of a liquid can be described by means of an empirical equation suggested as early as 1921 byVogel: η=A exp.B/(T−T 0), which, besides the temperatureT, contains three adjustable structuredependent parametersA, B andT 0.

Magnetic nanoparticles are small spherical particles at the size of 7-20nm, made of magnetic material (such as magnetite) and are usually coated by a biocompatible material (such as polyethylene glycol). These particles can be used in several medical applications such as drug delivery and MRI contrast enhancement.

Polymeric Systems with Antithrombin Activity for Thermally Activated Targeting
Applied Biochemistry and Microbiology, 2003Copolymers of N,N-diethylacrylamide and N-acryloylphthalimide with lower critical solution temperature (LCST) were synthesized by radical copolymerization. Polymeric systems with antithrombin activity and LCST were prepared via a reaction of amino groups of hirudin with phthalimide groups of the copolymers.

A material is considered which has one or more thermally activated linear response functions that obey Boltzmann statistics to good approximation. These response functions may, for example, be mechanical or dielectric relaxation times, diffusion coefficient, viscosity, etc.
