In-situ Battery Discharge Studies of Thermal Batteries using Transition Metal...
Thermal batteries find use in applications such as emergency power systems and ejector seats in aircraft. They operate at elevated temperatures of around 400-500 °C, where the... -
Unusual polymorphism in sodalites
We have recently observed extraordinary polymorphism on cooling various sodalites under vacuum. Materials undergo a phase transition followed by a fully reversible... -
The quest for fully hydrogen-ordered ice XIV
Water ice displays a remarkably complex phase diagram containing pairs of hydrogen-ordered / disordered phases. Ice XII is a hydrogen-disordered phase and ice XIV is its... -
Local ordering in the pressure-induced order-disorder transition in ammonium ...
Ammonium bromide undergoes a pressure-induced order-disorder transition, where the disordered (plastic) phase is thought to consist of a random distribution of ammonium cations... -

Phase transitions in melamine at high pressure
Melamine is a common organic molecule based on a six-sided ring; this unit typically connects with itself or other organic species to form layered crystal structures, which then... -
Magnetic and Structural Studies on Oxychalcogenides
In this proposal we request 3 days of beam time on HRPD to study the structures (both atomic and magnetic) of a variety of oxychalcogenide phases: La2O2Se2Fe2O, Ce2O2Se2Mn and... -
SANS investigation of cross-linking in irradiated greases
Greases used in harsh radioactive environments are showing microstructural damages. These defects cause changes in the physical and chemical properties of materials, which in... -
