Paulo Brant Carvalho, Brazilian

Paulo CarvalhoI hold a BSc in Chemistry from the University of Sao Paulo, an 8-semester's program with a solid and diversified curriculum in the several aspects of the field and in particular in analytical chemistry, spectroscopy and its applications. I have concluded a Masters in the Advanced Spectroscopy in Chemistry European Program, a 2-year program hosted at two renowned universities in Europe, University Lille 1 and the Jagiellonian University of Krakow. I chose the identification of Lewis acid sites formed on zeolites during the dehydration process as the topic of my master thesis, for which I got to perform density functional theory (DFT) calculations and modelling of those Lewis acid sites, followed by the generation of theoretical x-ray absorption near-edge structure (XANES) spectra for further interpretation of the experimental data.

My PhD project is on the exploration of pressure-induced amorphisation and glassy states of clathrate hydrates (CHs). CHs are icy structures water forms with polyhedral cages enclosing small concentrations of guest molecules under extreme conditions. They occur in nature in the deep sea floor sediments and may be present on the surface of celestial bodies like Titan, one of Saturn's satellites. For that, CHs have important industrial and environmental applications. Neutron scattering is applied on the scanning process of the different phase transitions, giving rise to valuable information on the fundamental aspects of CHs and ices and providing insight into water-guest hydrophobic interactions and proxy systems for probing water's anomalous properties at low temperatures and high pressures.
