Professor Kosmas Prassides

Kosmas Prassides was born in Kavala, Greece and read Chemistry at Oxford University where he also completed his doctoral research on inorganic mixed valency compounds under the supervision of Professor P. Day FRS.
He was then the Drapers' Research Fellow at St. Anne's College, Oxford, working closely with Professor P. N. Schatz (University of Virginia) on the development of the PKS theoretical model for mixed valency systems. Following a spell as Assistant Professor of Chemistry at the University of Crete, Greece, he returned in 1989 to the UK at the University of Sussex where he remained until 2004 and he was successively Lecturer, Reader and Professor of Solid State Chemistry.
In 2005, he took up a Chair in Materials Chemistry at the Department of Chemistry, Durham University. In October 2014, he relocated to Japan as a Professor at Tohoku University and Principal Investigator at the Advanced Institute for Materials Research (WPI-AIMR). In October 2018, he accepted a Chair in Materials Science at the Graduate School of Engineering, Osaka Prefecture University. He remains a visiting Professor at AIMR.
His research interests are multi-disciplinary and encompass a range of structural, magnetic and electronic problems in modern materials, straddling the areas of condensed matter physics and chemistry.
His primary focus is currently on the study of strongly correlated electron systems, which typically display remarkable electronic properties that challenge existing theory for satisfactory explanations. The delicate balance between localised and itinerant behaviour related to the strongly correlated nature of the systems and the metallic, insulating and superconducting states lie at the heart of his ongoing research.
He has been using core chemical approaches to access unusual structures and electronic, conducting and magnetic ground states and probe the physics in key materials, especially metal fulleride solids. He has advanced the understanding of molecular superconductivity and magnetism and the generic problem of the metal-Mott insulator transition, unveiling the fullerides as model members of the high-Tc superconductivity family, potentially holding the key to the understanding of the pre-requisites for high-Tc superconductivity when electron correlation is important.

[Research Theme]
Synthesis, design, and assembly of sub-nano, nano, micrometer-scale object toward materials with novel and unique functionalities. Crystalline building blocks of layered hydroxides, layered oxides, and metals are prepared based on a solution technique and assemble them into specific fine structures, such as porous, oriented, and/or periodic structures. The formed structured materials show extraordinary functionalities, for instance, excellent electrochemical performance, strong photoluminescence enhancement, large adsorbent affinity, selective catalytic activity, etc. Systematic investigation about a relation of fine structures and functionalities will enables us to access the materials with unexpected characteristics.

[Research Theme]
My research interests are in the relationship between crystal structures and physical properties of novel materials, such as molecular superconductors and magnets.
Prominently, my research addresses the properties of unconventional fullerene-based superconductors which are isotropic 3D molecular solids. I aim to control the physical properties by chemical (composition) and physical (pressure, temperature, magnetic field) manipulation and access novel electronic states of matter. My research expertise encompasses a variety of experimental techniques at both ambient and elevated pressures (synchrotron X-ray and neutron diffraction, magnetometry, thermodynamic and transport measurements, μSR spectroscopy).

[Job Theme]
The goal of my work is to be a bridge between our laboratory members and other counterparties. I believe better communication is always the key to any success, and I learnt it from previous life experiences. Born and raised in Miyagi, I studied in Sendai until junior college and moved to the US for earning BS in business management. After spending 10 years in America, I came back to Sendai and joined an international NGO to rehabilitate several child day-care facilities which were damaged by the tsunami. I am excited to be the part of Prassides laboratory group, and please feel free to stop me for "Hi !"
