Newly Discovered Minerals Reveal Anomalous Origins

Researchers characterized two highly unusual nickel-containing minerals, both unearthed in an ancient geological site in southern central Siberia. The findings extend our understanding of naturally occurring mineral species and varieties and provide useful insights into the environments leading to the formation of potentially valuable mineral ores.

Curtis Gomez, Electrical Safety Officer

Curtis Gomez recently became the ALS electrical safety officer. Besides looking out for hazards, his work in motor controls coordination draws from a TV and radio background—and working for a local band that made it big. Read more »

Infrared Nano-Mapping of Local Strain in 2D Materials

Researchers have demonstrated an infrared technique to map and analyze strain in atomically thin crystals of hexagonal boron nitride (hBN) at the nanoscale. This ultrasensitive strain-imaging method could be a promising tool for the examination of low-dimensional materials of interest for electronic and photonic devices. Read more »

Fundamental Property of Arginine Revealed Through Solvation

Just 20 amino acids act as building blocks for all our proteins, but their chemical properties have been difficult to study at the most fundamental level. Combining experiments and theory at the ALS, researchers have now determined the ionization energy of arginine, an amino acid with over 100 isomers. Read more »
