Report Introduction:

The building blocks of all materials known to man are derived from the 90 naturally occurring elements in the periodic table. While some of these elements are abundant and cheap, many technologically important ones are either scarce or expensive. The superatom concept developed more than 20 years ago, allows the possibility to overcome this limitation of the periodic table and helps to design and synthesize an entirely new class of materials nature has not been able to do. Superatoms are clusters of atoms with specific size and composition that mimic the chemistry of atoms in the periodic table. Understanding the structure-property relationships of these superatoms is a key to the development of a theory-led design and focused discovery of materials with tailored properties. This talk will describe how simple electron counting rules developed over the last century can be used to design these superatoms by paying particular attention to the group 17 elements, the halogens. I will show how complex clusters known as super- and hyper-halogens can not only mimic the chemistry of halogens, but also have far superior properties, allowing the synthesis of strong oxidizing agents, safer materials for hydrogen and electrochemical storage, photo-voltaic materials with tunable band gaps, and high energy density materials.
 

About Speaker:
　　Dr. Dmitry Terentyev was born in 1979 in Leningrad (now St. Petersburg) Soviet Union. He graduated at Polytechnic University of St. Petersburg (Russian Federation) at the department of Physical Mechanical Engineering in 2002. In the period of 2002-2006 he accomplished PhD at University Libre de Bruxelles (Belgium) working on the "Modeling of Radiation Damage in high-Cr steels for Fusion Applications". In 2007, he was employed as researcher at Belgian Nuclear Research Centre as responsible for the atomistic modeling activities in fusion and fission structural materials. In 2014, he became a Head of Fusion Research Unit at Belgian Nuclear Research Centre.
