Influence of non hydrostaticity and Fe-Fe correlation on iron spin state crossover in (Mg,Fe)O

Dr. Konstantin Glazyrin

The solid solution of MgO and FeO -(Mg,Fe)O or ferropericlase is an important example of a simple solid state system incorporating a transition element... read more

Methodological developments: A new compact diamond anvil cell design for low temperature nuclear inelastic X-ray scattering applications

Dr. Konstantin Glazyrin

We designed, made and tested a new cell to overcome limitations of the most of existing designs – currently used cells ... read more

High-pressure synthesis and crystal chemistry of novel ionic polynitrogen entities as the future's high energy density materials

Dr. Dominique Laniel

How can we reduce the travel time to Mars while carrying a heavier load of equipment and personnel? How can we ensure that launching spaceships does not further pollute the Earth? The answer to these questions is... read more

Nuclear Magnetic Resonance at multi-megabar pressures

Dr. Thomas Meier

Implementation of spectroscopic methods probing local electronic properties of electrons or nuclei in condensed matter at extreme conditions remains a challenging endeavor. Under sufficient conditions... read more

High-pressure high-temperature synthesis and investigation of physical properties of novel transition metal oxides and other materials

Dr. Sergey Ovsyannikov

On one hand, creation of novel materials at extreme HP-HT conditions often brings unexpected insights into the chemistry and physics of materials, thereby contributing to the fundamental sciences. On the other hand... read more

Towards new crystal chemistry: High-pressure evolution of oxides with tetrahedral framework and layered structures

Dr. Anna Pakhomova

The properties of solid matter drastically change upon compression. What is the correlation between chemistry, crystal structure and compressibility for different compounds? This is the question relevant for both Earth sciences and solid state chemistry... read more

Exploring icy satellites

Dr. Anna Pakhomova

Presence of a hydrosphere on a planetary body implies potential habitability. That is the reason why icy satellites featuring a hydrosphere in their interiors attract nowadays much attention of astrobiologists... read more

Iron-water system at high pressure

M.Sc. Egor Koemets

Water or water-bearing species from crust and to the lower mantle has a strong impact not only on life on our planet but also on numerous processes in Earth’s interiors. Presence of water affects chemical and physical properties of mantle minerals, changes melting temperatures, sound velocities and viscosity of materials, and causing... read more

Crystal chemistry of dense silicates at pressures and temperatures relevant for Earth lower mantle

M.Sc. Iuliia Koemets

Global carbon cycle has a great impact on the climate changes, being responsible for example in the past for NeoProtezoic “snowball” Earth and Cretaceous warm period. While quantity of carbon on our planet is still uncertain, there is general consensus that deep Earth is the main reservoir of carbon-bearing compounds... read more

Study of the efficiency of various anvils for dsDACs

B.Sc. Alena Krupp

As the use of conventional diamond anvil cells is limited to ~ 400 GPa, there has been a recent development to extend the pressure range up to the terapascal by using secondary stage anvils and special shape designs. This extension enables ... read more

Metal hydrides at high pressures

M.Sc. Alena Aslandukova

Room-temperature superconductivity is one of the most attractive but very difficult research areas in nowadays solid-state physics due to its both theoretical and experimental complexity... read more

Transition metal carbonitrides at high pressure

M.Sc. Andrey Aslandukov

The design of novel superhard materials is based on the combination of a transition metal (TM), characterized by high valence electron density, with the first-row elements, which form strong short covalent bonds... read more
