AbstractThis article discusses the use of electrostatic cleaning technology to remove loose particulate surface contamination - which here includes microbial contaminants such as spores, conidia and hyphal fragments - from two 19th century albumen photographs mounted on cardboard. The results of this study, obtained using light microscopy, SEM/EDX and microbiological methods, as well as conservators' visual evaluation, show that the technology is fundamentally suitable for removing microbial contamination from photographic prints and their cardboard mounts. Cleaning the surface four times with electrostatically charged foils reduced the microbial contamination by up to 70%. The surface of the albumen print, which is sensitive to abrasion, was not harmed, and its characteristic features were not changed. The photographs, which were partly delaminated from the cardboard support and the mechanically weakened cardboard, could be treated without creating any additional damage.

Spectroscopic ellipsometry has been successfully used to characterize the CdS/CdTe heterojunction solar cell deposited on TEC15 glass. The effects of copper treatment on the optical properties of a cadmium chloride treated photovoltaic device were investigated using ellipsometry. No changes in either the band gaps or critical points of CdTe layer were noticed as a result of copper treatment. The copper treated CdTe layer exhibited a higher refractive index in the visible and longer wavelengths (≤3 eV), as compared with the untreated layer. This was attributed to the increased disorder in the case of copper treated layer.
