Bare titania and metal-promoted TiO2 catalysts were employed in the treatment of nitrates, which are ubiquitous pollutants wastewater. The results show that process can be carried out under visible light (from a white LED lamp) and, best case, 23.5% conversion nitrate was obtained over 4 h with full selectivity towards N2 by employing 0.1 mol% Ag/TiO2 prepared flame spray pyrolysis. Moreover, p...

In this paper we analyze whether simple indicators related to photo quality (brightness, sharpness, colour palette) and established content detection techniques (face detection) can predict the success of photos in obtaining more “likes” from other users of photo-sharing social networks. This provides a unique look into the habits of users of such networks. The analysis was performed on 394.000...

During recent decades metallic nanoparticles have been found very interesting due to their unique characteristics which make them suitable for different applications. In this research, for the very first time, we tried to perform selective surface photo activation chemistry on the targeted facets of nanoparticles while they are in suspension. This technique enabled us to form desired assemblies...

This paper is a definition of photo elicitation and a history of its development in anthropology and sociology. The view of photo elicitation in these disciplines, where the greatest number of photo elicitation studies have taken place, organizes photo elicitation studies by topic and by form. The paper also presents practical considerations from a frequent photo elicitation researcher and conc...

According to the modern conceptions the cholesteric liquid crystals (CLCs) can be considered as one dimensional 1D) photonic crystals. The existence of the selective reflection band and the ability to change the selective reflection avelength over a wide range under the action of applied external forces make it possible to use the CLCs in the data ecording, processing and storage systems. Prese...
