Tulsi defended her dissertation on “Hybrid Additive Manufacturing of Ferroelectric Oxides and Aerospace Alloys” last Tuesday, November 20th, 2018. Her work involved integrating functionality into metallic structural components using additive manufacturing. She will begin an NRC Research Associateship at the Air Force Research Laboratory early 2019, researching new ceramic matrix composite systems for high-temperature aerospace applications.
Dr. Sanjubala Sahoo and colleagues have provided insight for the origin of high catalytic activity for graphene-supported single transition metal atoms for activation of methane molecules. The paper entitled “Graphene Supported Single Atom Transition Metal Catalysts for Methane Activation” published in ChemCatChem, Volume 10, page 3229 (2018) co-authored by S. Sahoo, S. L. Suib and S. P. Alpay was a cover feature for the journal.
Yomery Espinal wrapped up her PhD work on 8/2/2018. In her thesis entitled “Design and Synthesis of Functional Nanocomposites for Electronic Applications,” Dr. Espinal concentrated on ferroelectric heterostructures and composites. Her work was partially supported by Army Research Labs. Congratulations from the entire group!
Sanjubala Sahoo and colleagues provide an atomistic level understanding for the interaction of titanium with atmospheric molecules such as oxygen, nitrogen and hydrogen as a function of temperature and gas partial pressure.
