UD's Bobev receives NSF Early Career Award for research on novel compounds of rare Ea...(caloric effects which are the basis of c...)

caloric effects, which are the basis of cooling technologies for refrigeration, and colossal magnetoresistance, a phenomenon essential for storing vast amounts of data on computer hard drives, emphasize how many challenges and opportunities still lie ahead to deepen our understanding of the chemistry and physics of these ostensibly simple substances, according to Bobev.

Thus, from an academic prospective, one can recognize the value of the systematic analysis of the fundamental characteristics of any type of old or new compounds--this is what will give us new, valuable insights into the principles governing the structures and properties of such materials, Bobev notes.

Bobev and his group will develop the synthetic chemistry of the new compounds using state-of-the art techniques available at UD. The group will then analyze the crystal chemistry of the compounds and their properties using powder and single-crystal X-ray diffraction, scanning electron diffraction, and magnetometry. A portion of the experiments is expected to be conducted at the U.S. Department of Energy's Los Alamos and Argonne National Laboratories. Ultimately, the study's findings may aid scientists in tuning compounds for specific applications, he says.

Integrated with the research will be new lecture course modules on solid-state chemistry for UD graduate and undergraduate students and laboratory experiments focusing on advanced characterization techniques for hard materials.

Such research experience in solid-state chemistry will provide excellent opportunities for the students to become aware of synthetic and analytical tools that are not available in any of the undergraduate teaching labs, Bobev says.

Bobev received his master's degree in physical chemistry from the University of Sofia in Bulgaria and his doctorate in inorganic/solid-state chemistry from the University of Notre Dame. He was a postdoctoral fellow at the Los Alamos National Laboratory be
