Mr. Abhisek Chakraborty worked as a Researcher at the Institute of Inorganic Chemistry in the Czech Republic from June 2009 to December 2011. He prepared and characterized photocatalytic titanium dioxide layers on solid substrates from aqueous solutions. Through his work, he was able to prepare high quality layers and determine their photocatalytic properties and structural characteristics. Some of his results were planned for future publication. His experience with preparing oxidized thin layers was evaluated as very good.
