Two New Molecular Nitrogen Phases near Megabar Pressures
Alexander F. Goncharov, Elena Bykova, Iskander Batyrev +7
Molecular nitrogen exhibits remarkable structural diversity near the polymeric transition, where multiple phases are metastable. Here, we report two new molecular phases. The first…
Isostructural phase transition and equation of state of type-I and type-VIII metallic sodium borosilicide clathrates
M. Demoucron, S. Pandolfi, Y. Guarnelli +10
Electronic properties of silicon-based clathrates can be tuned by boron incorporation into the silicon cage network. Sodium borosilicides clathrate outstands with uncommon stoichio…
Hydrogen-rich hydrate at high pressures up to 104 GPa
Alexander F. Goncharov, Elena Bykova, Iskander Batyrev +10
Gas hydrates are considered fundamental building blocks of giant icy planets like Neptune and similar exoplanets. The existence of these materials in the interiors of giant icy pla…
Polymorphism of monatomic iodine
Alexander F. Goncharov, Huawei Chen, Iskander G. Batyrev +8
We applied synchrotron single-crystal X-ray diffraction in a diamond anvil cell at 48-51 GPa and first-principles theoretical calculations to study the crystal structure of solid a…
High entropy alloys and their affinity to hydrogen: from Cantor to platinum group elements alloys
Konstantin Glazyrin, Kristina Spektor, Maxim Bykov +7
Properties of high entropy alloys are currently in the spotlight due to their promising applications. One of the least investigated aspects is the affinity of these alloys to hydro…
Polytypism of Incommensurately Modulated Structures of Crystalline Bromine upon Molecular Dissociation under High Pressure
Yuqing Yin, Andrey Aslandukov, Maxim Bykov +14
Polytypism of incommensurately modulated structures was hitherto unobserved. Here, we found the phenomenon in simple halogen systems of bromine and iodine upon molecular dissociati…
