Intermediate Valence State in YbB4 Revealed by Resonant X-ray Emission Spectroscopy
CHEXS users have directly observed an electronic configuration that is quantum mechanically mixed between the Yb2+ and Yb3+ valence states in the material YbB4. These observations confirm an “intermediate valence” conjecture for this material, which was first hypothesized 50 years ago.
Dynamics of Recrystallized Grains in a Hot-Compressed Mg-Zn-Ca Alloy
Recent research performed at CHESS presents new insights into the microstructural evolution which occurs during annealing of Mg alloys using in-situ X-ray diffraction. These alloys have potential to make vehicles lighter and reduce greenhouse gases.
Students of Puerto Rico Designing Techniques of HMF at CHESS
The Cornell High Energy Synchrotron Source, CHESS, and the University of Puerto Rico are continuing a collaboration that will shape the future of the synchrotron X-Ray laboratory as it builds the new High Magnetic Field facility, HMF.
Characterization of 128 x 128 MM-PAD-2.1 ASIC: a Fast Framing Hard X-ray Detector with High Dynamic Range
Hybrid pixel array detectors (PADs) have proven to be powerful, versatile area detectors for X-ray science. A new prototype would enable significant advances in time-resolved studies of dynamic phenomena.
Unconventional Hysteretic Transition in a Charge Density Wave
In a new paper appearing in Physical Review Letters, research co-first-authored by postdoctoral fellows Baiqing Lyu (MIT) and Alfred Zong (Berkeley) and a team lead by Prof. Nuh Gedik (MIT), claim that EuTe4 sets a new record for hysteresis in a crystalline solid.
