Through diligent chemistry work on purifying small gold nanoparticles and then reintroducing a variety of additives, Yixuan Yu and his fellow students from the Korgel group at the University of Texas at Austin have found the key ingredient to the mysterious phenomenon of cooperative Ostwald ripening. 

For the last decade, the Tristram-Nagle/Nagle lab (Carnegie Mellon University) has been working on the interaction of HIV-1 peptides with specific membranes in the HIV virion, T-cell plasma and nuclear membranes (see references below).

During the last week of May, twelve high school students and two high school teachers visited CHESS from Oakville, Ontario.

Nanorods are elongated nanoparticles with aspect ratios of typically 3:1 to 10:1 and thus have interesting structural and optical anisotropies. 

Back by popular demand: MacCHESS' Richard Gillilan is heading up another international training course in Small Angle Scattering (SAS) at the annual meeting of the American Crystallographic Association this summer in Philadelphia.

Canine parvovirus (CPV) is closely related to the feline panleukopenia virus (FPV), also a parvovirus, that infects domestic cats and some non-domestic carnivores.

CHESS veteran Ashley Bucsek, a graduate student from the Colorado School of Mines, won a 2015 NSF Graduate Research Fellowship for her thesis work developing data analysis theory and models for studying phase transformation and twinning in metallic alloys using far field high-energy diffraction microscopy (HEDM). 

In a recent ACS MacroLetters article Yu Ho Wen, Jennifer Schaefer, and Lynden Archer from the Cornell School of Chemical and Biomolecular Engineering report on a systematic study using small-angle x-ray scattering at CHESS to map the structural relaxation for colloidal glasses.
