Pressure has long been recognized as a fundamental thermodynamic variable but its
application was previously limited by the available pressure vessels and probes. The …

In molecular photochemistry, charge-transfer emission is well understood and widely
exploited. In contrast, luminescent metal-centered transitions only came into focus in recent …

At the 26th AIRAPT conference in 2017, a task group was formed to work on an International
Practical Pressure Scale (IPPS). This report summarizes the activities of the task group …

Producing metallic hydrogen has been a great challenge in condensed matter physics.
Metallic hydrogen may be a room-temperature superconductor and metastable when the …

Defect centers in wide-band-gap crystals have garnered interest for their potential in
applications among optoelectronic and sensor technologies. However, defects embedded in …

Our ability to interpret seismic observations including the seismic discontinuities and the
density and velocity profiles in the earth's interior is critically dependent on the accuracy of …

The ambient temperature equations of state (EoS) of iron, cobalt, nickel, zinc, molybdenum,
and silver have been measured by x-ray diffraction. These transition metals were …

The ruby luminescence method is widely used for pressure measurement in the diamond
anvil cell and other optically transparent pressure cells. With this application in mind, we …

The compression curve of iron is measured up to 205 GPa at 298 K, under quasihydrostatic
conditions in a diamond anvil cell. Above 150 GPa, the compression of this metal is …

Luminescence manometry is a rapidly expanding field focused on the optical measurement
of pressure across both low and high-pressure regimes. It presents a compelling alternative …
