Polyimides are widely used for the external surfaces of spacecraft. In low Earth orbit (LEO), they are exposed to atomic oxygen (AO) and to problems of electrostatic discharge (ESD). This work demonstrates that liquid-phase deposition (LPD) of titania creates a protective coating on Kapton polyimide that is effective in reducing AO-induced surface erosion and in preventing ESD. Adherent titania...

A device is described for studying thermodynamic and surface characteristics of metals as well as for differential thermal analysis of materials. A promise its shown is application for a multiple examination of high-temperature capillarity in a number of technological processes involving the formation or contribution of a liquid phase.

The use of ionic liquids (ILs) as a solvent for thermal lens measurements has been investigated. It was found that ILs provide a better medium for thermal lens measurements than water. Specifically, not only the ILs offer at least 20 times higher sensitivity than water but that the enhancement can be appropriately adjusted by changing either the cation or the anion of the ILs. For example, the ...

We report a sensitive single-beam technique for measuring both the nonlinear refractive index and nonlinear absorption coefficient for a wide variety of materials. We describe the experimental details and present a comprehensive theoretical analysis including cases where nonlinear refraction is accompanied by nonlinear absorption. In these experiments, the transmittance of a sample is measured ...
