IMG_0532_AK_NIESMy visit at National Institute for Environmental Studies (NIES) in Tsukuba (Japan) was held from 26 March to 2 June 2014 as a part of Work Package 2 Carrying out experiments to produce necessary (missing) data for nanoparticles”.

The characterization of twenty photocatalysts was successively carried. The first type of photocatalysts was NaTaO3 modified with noble metal nanoparticles (Au, Ag, Pd). Next types of photocatalysts were single, two and three-semiconductor nanocomposites obtained by using hydrothermal method. Samples of semiconductor nanocomposites were modified in various amount and different combinations of TiO2, MoS2, CdSe, KTaO3, WO3 nanoparticles. Correlation between amount, type and combination of metals on the properties nanoparticles were investigated. The aim of the study was to get measurements by Specific Surface Area analysis, phase composition and size crystals using X-ray diffraction (XRD).

I also had an opportunity to listen to a lecture presented by Guenter Oberdoerster, D.V.M., Ph.D. from University of Rochester Medical Center in USA: “Comparative risk assessment of airborne nanomaterials: analyzing exporure – dose – response relationships”. The NanoBRIDGES project gave me a possibility to enrich culturally and scientifically.
