Abstract and Biography

Recent two decades of research on silver(II) fluorides led to realization of their unusual properties, encompassing: marked covalence of Ag–F bonds [1], strong Ag-Ag superexchange [1,2], atypical high pressure phase transitions [3], and close similarity to copper(II) oxides [1,2,3,4] and to BaBiO3 [4] (magnetic/CDW precursors of superconductivity). When properly nanoengineered and doped, Ag(II) fluorides could become superconducting [1] with TC up to ca. 200 K [5]. Novel “chemical capacitor” setup opens a nice route to achieve doping [5,6].

Professor Wojciech Grochala’s (ur. 1972) career has been linked to the University of Warsaw (M.Sc. 1995, Ph.D. 1998, D.Sc. 2005, prof. extraord. UW 2011, prof. titular 2014, prof. ord. UW 2016). Since 2004 he leads the Laboratory of Technology of Novel Functional Materials. He spent postdoctoral stays in the USA (with Roald Hoffmann, Nobel Prize winner, at Cornell Univ.) and in the UK (with prof. Peter P. Edwards at Univ. of Birmingham). He was visiting professor at Geophysical Lab, Carnegie Institution of Washington and Cornell University. Prof. Grochala coauthors over 200 papers and book chapters as well as 3 international patents. He has promoted twelve PhD and lectured one hundred times at scientific institutes worldwide; he coauthored over two hundred fourty conference contributions. His scientific interests are in materials, inorganic, physical and computational chemistry (particularly for solids) and more recently also organic chemistry. He explores new materials for hydrogen storage, atypical compounds of divalent silver, magnetic materials and compounds of noble gases (particularly the lightest ones). For several years he has been teaching to the students of humanities at Artes Liberales College. Growing exotic plants is his hobby, so is prose and poetry writing.
