    Abstract: Performing chiral photodetection, photocatalysis or photochemical reactions at the molecular level has always been a nearly impossible task, due to the very low efficiency of the generated optical circular dichroism signals. On the contrary, chiral colloidal nanocrystals have been shown recently to offer a very large differential response to circul... Show More

    Abstract: From the technological point of view, the synthesis of carbon nanotubes (CNTs) aims at optimizing their field emission properties. Among all the synthesis methods, the CVD method is the most suitable for the growth of carbon nanotubes. In this method, transition metal atoms (Fe, Ni, Co) are used. The carbon nanotubes obtained with these transition ... Show More

    Abstract: In recent times, iron oxide based magnetic nanoparticles (mainly magnetite (Fe3O4) or maghemite (γ-Fe2O3)) as well as clay and clay based composites, have become very important in the elimination of persistent organic compounds from waste water systems. This has been carried out by magnetic assisted chemical separation (MACS) process. The feasibili... Show More
