We present some results concerning deposition of silicon oxide layers SiOx-type onto glass plates. Such nanostructured layers of ca. 25 nm were deposited under vacuum at 60º incidence angle. The layers were further functionalized to bind proteins. The layers were characterized by Fourier transform infrared spectroscopy and X-ray- photoelectron spectroscopy. We found that the silicon monoxide amount in the deposited samples is small and decrease more by a hydrophylization oxygen plasma treatment. Liquid crystal cells were then obtained to observe the molecular alignment imposed by such treated glass plates. The planar orientation of the liquid crystal molecules was observed in all the studied cases. A rather strong interaction of the organic layers with the substrate was then advanced leading to observed orientation..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
