Light-metal hydride and amide systems are currently among the most promising materials for reversible hydrogen storage. In this proposal, we ask for 3 days on POLARIS or GEM to... -
Pressure Tuning of Sodium Battery Materials: PART II
This is a continuation proposal to the previous study (RB. 1720418) of NaCoO2. Even if the data analysis is still under process, the result could indicate that the transition... -
Thermal expansion of kyanite, andalusite and sillimanite
Al2SiO5 forms three naturally-occurring polymorphs, kyanite, andalusite and sillimanite. These minerals are produced by varying degrees of metamorphism of sedimentary rocks, the... -
Thermal expansion of Mg: pre-melting effects in hcp metals and the Earth's in...
Ab initio computer simulations have suggested that pre-melting phenomena occur in the elastic properties of hcp-iron at the conditions of the Earths inner core just before... -
Pressure-Tuning Interactions in Spin-Crossover Metal-Organic Frameworks
The magnetism of spin-crossover (SCO) materials containing Fe(II) can be switched by changing conditions. The low-spin state existing at low temperature or high pressure can be... -
