The catalyst-free sonogel route was implemented to fabricate highly pure, optically active, hybrid azo-dye/SiO2-based spin-coated thin films deposited onto ITO-covered glass substrates. The implemented azo-dyes exhibit a push-pull structure; thus chromophore electrical poling was performed in order to explore their quadratic nonlinear optical (NLO) performance and the role of the SiO2 matrix for allowing molecular alignment within the sonogel host network. Morphological and optical characterizations were performed to the film samples according to atomic force microscopy (AFM), ultraviolet-visible (UV-Vis) spectroscopy and the Maker finger technique. Regardless of absence of a high glass transition temperature (Tg) in the studied monomeric liquid crystalline azo-dyes, some hybrid films displayed stable NLO activity such as second harmonic generation (SHG). Results show that the chromophores were homogeneously embedded within the SiO2 sonogel network, where the guest-host molecular and mechanical interactions permitted a stable monomeric electrical alignment in this kind of environment.

Searching for Room Temperature Superconductors

Authors: Frank Lichtenberg
Comments: 66 pages

The interesting and fascinating physical phenomenon of superconductivity appears, until now, only at very low temperatures and therefore its technical application is limited to relatively few areas. If it is possible to create materials which are superconducting at room temperature, then this could initiate a revolution in technology. More than 10 years fundamental research, experience, knowledge and ideas in the field of special materials (oxides) lead to the conviction that superconductivity at room temperature is possible, and together with Global Scaling - a new knowledge and holistic approach in science - to an extended approach on the search for room temperature superconductors. This presentation is divided into a main part (28 pages) and an appendix (38 pages). A content overview of this presentation is shown on the following pages 3 and 4.
