Extreme conditions have been at the forefront of scientific advancement for over a decade, pushing new technologies that will soon revolutionize the world we live in. The Nevada Extreme Conditions Laboratory is interested in the toughest questions at the extremes of temperature, pressure, field, time and more in materials related sciences. NEXCL aims to lead the way in the discovery and understanding of materials with these extremes that will have the greatest societal change, addressing energy and climate issues. Our interdisciplinary center combines expertise in high-pressure and high-temperature techniques; optical and X-ray spectroscopy; theoretical and computational methodologies; and large-scale user facility, synchrotron and free electron laser experiments.
