Thermal structure of clean and contaminated free

The thermal structure of clean and contaminated free-surfaces subject to the transient flow of a gas jet were investigated experimentally. The interface and near-surface flow were examined using optical high-speed (HS) motion analysis, infrared (IR) imagery, and laser-induced fluorescence (LIF). IR imagery revealed an instability in the form of thermal scars on the expanding circular ...

bed rails, the bed surface, and the supply cart, on the basis of their observed frequency of contact.12 Developing an un-derstanding of which sites are more likely to be contaminated with pathogens can guide infection control practice and direct new innovations.

Leed studies on a clean and contaminated Pd?110?

Low energy electron diffraction from a clean and carbon contaminated Pd{110} surface has been studied over the temperature range 100-800 K and evidence for a phase transition on the clean surface near 250 K is found. Residual carbon on or in the surface layer causes shifts in the energies of peaks in intensity versus energy spectra which correspond to an average outward expansion of about 4% ...
