Extreme conditions research cannot be accomplished without state-of-the-art instruments. Thus, tools must be improved in order to access new domains and to expand the range of properties measured. In high pressure neutron diffraction, for example, one limitation that sample sizes need to be much larger than is the case for x-ray...

Extending his original predictions for metallic hydrogen, Cornell's Neil Ashcroft later proposed that hydrogen-rich materials containing main group elements might exhibit superconductivity at accessible pressures. The hydrogen in these structures, he argued...

Most of the entropy in materials comes from the vibrations of atoms. This vibrational entropy depends on the frequencies of phonons, or lattice vibrations, which change with P and T. Knowing the vibrational frequencies is essential to understanding the Gibbs free energy at elevated P and T. Usually the...

It is difficult to overestimate the importance of silicon when it comes to computing, solar energy, and other technological applications - not to mention the fact that it is the second-most abundant element in Earth’s crust, in terms of mass percent. The most common form of silicon crystallizes in the same structure as diamond, but other...
