Safety, Health, Environment and Risk Management’s (SHERM) mission is to work in conjunction with the UTHSC-H community to ensure that education, research, and health care services activities take place in conditions that are optimally safe and healthy for all student, faculty, staff, visitors, surrounding community and the general public. . 6-x. Au. x. system hosts the first known example of an elastic quantum critical point. Neutron and x-ray diffraction measurements were performed to study the structural properties as a function of temperature and Au-composition. First principle calculations confirm that the phase transition is driven by an elastic instability and is independent of electronic properties. Heat capacity measurements indicate the presence of quantum fluctuations at the critical composition. X-ray. What . is . X-ray. . Diffraction?.
