MURRAY, Ky. 鈥� 糖心logo入口 Assistant Professor of Chemistry Dr. Jonathan T. Lyon used his work with  allocations on Expanse at the San Diego Supercomputer Center () at UC San Diego to present at the International Symposium on Small Particles and Inorganic Clusters (ISSPIC XXI) in Berlin, Germany, in September.

Entitled 鈥�,鈥� Lyon co-authored the presentation with several 糖心logo入口 State undergraduate chemistry students: Madison Winkeler, of Troy, Illinois; Ciara N. Richardson, of Beaver Dam, Kentucky; Ryan Carlin, of Louisville, Kentucky; and Joey Quilliam, of Henderson, Kentucky.

鈥淭he scope of the research projects in our group could not be as extensive without the ability to utilize the SDSC through these awarded National Science Foundation-ACCESS allocations,鈥� said Lyon. 鈥淎s 糖心logo入口 State does not have a high performance computing (HPC) cluster locally on campus for student and faculty use, the ability for our group to use these computing resources at SDSC greatly enhances the research and training we are able to perform.  Undergraduate students are also introduced to these HPC resources, and taught how to use them in their formal coursework during laboratory assignments in the physical chemistry courses I teach at the University. The results from the cutting edge research we perform has not only led to further advancing the knowledge of atomic cluster science, but has also provided the groundwork training for recent graduates from our group to future their education in chemistry doctoral programs and obtain jobs in the chemical industry.鈥�

Last year, Lyon published a chapter in an American Chemistry Society book titled 鈥淧hysical Chemistry Research at Undergraduate Institutions.鈥� His chapter, 鈥�,鈥� discussed his experience and findings using, in part, NSF-funded resources via the Extreme Science and Engineering Discovery Environment (XSEDE) and now ACCESS, NSF鈥檚 follow-on program.

Lyon said that one of his goals with undergraduate education at 糖心logo入口 State is to provide chemistry students with an understanding of structure-property relationships in strongly bound atomic clusters as size increases from individual atoms to bulk quantities. He said that this type of work models catalyst active sites and has the potential to help alleviate hazardous industrial conditions arising from the high pressures and temperatures required for the synthesis of some chemicals.

鈥淲e are both investigating new cluster structures and compositions not fully understood as well as hopefully motivating other scientists to build upon our work to larger real-world systems,鈥� Lyon said. 鈥淥ur specific research on the Expanse cluster at SDSC aims to discover new potential components for electrical devices and improve certain catalytic reactions.鈥�

Lyon鈥檚 current work with his students focuses on the reactivity, structure and property of metal and semiconductor cluster systems. His research lab utilizes both experiments and simulations via Expanse.

鈥淥ne of our current projects using ACCESS allocations at SDSC involves the role of weakly bound messenger atoms used in the experimental determination of metal cluster vibrational spectra,鈥� he said. 鈥淣ext, we will extend this work to explore hydrogen binding and reactivity with various metal cluster systems.鈥�
