Pressure is a fundamental thermodynamic variable that can be used to control the properties
of materials, because it reduces interatomic distances and profoundly modifies electronic …

The properties of catenated nitrogen molecules, molecules containing internal chains of
bonded nitrogen atoms, is of fundamental scientific interest in chemical structure and …

Synchrotron sources with high photon flux, small source size, and broad energy range have
revolutionized ultrafine characterization of condensed matter. With the addition of the …

The coupling of two or more molecules of dinitrogen (N2) occurs naturally under the
radiative conditions present in the ionosphere and may be achieved synthetically under …

Studies of polynitrogen phases are of great interest for fundamental science and for the
design of novel high energy density materials. Laser heating of pure nitrogen at 140 GPa in …

Nitrogen usually consists of molecules where two atoms are strongly triple-bonded. Here,
we report on an allotropic form of nitrogen where all atoms are connected with single …

The nitrogen triple bond dissociates in the 100 GPa pressure range and a rich variety of
single-bonded polymeric nitrogen structures unique to this element have been predicted up …

Group V elements in crystal structure isostructural to black phosphorus with unique
puckered two-dimensional layers exhibit exciting physical and chemical phenomena …

▪ Abstract Energetic materials are chemical compounds or mixtures that store significant
quantities of energy. In this review, we explore recent approaches to property prediction and …

Pressure profoundly alters all states of matter. The symbiotic development of ultrahigh-
pressure diamond anvil cells, to compress samples to sustainable multi-megabar pressures; …
