The 236th Electrochemical Society meeting was held in Atlanta during the week of October 13-17, 2019. Mahsa Ebrahiminia, an MSE Ph.D. student from Dr. Dmitry Bedrov group, presented her latest work on transport and mechanical properties of model solid electrolyte interphases (SEI) that she studied using atomistic molecular dynamics simulations and was awarded the second place at the Lithium Ion Batteries Symposium.
SEI is one of the key components in the Li-ion batteries that, on the one hand, protects electrolytes from electrochemical decomposition and suppresses the growth of Li dendrites, but on the other hand, creates additional resistance for Li-ion transport between electrodes. Mahsa’s simulations provide a molecular scale insight into mechanisms of Li-ion transport and structure-property relationships that hard to obtain from experiments but are badly needed in order to design new materials for next generation of batteries.
The National Science Foundation has awarded $1,635,591 to scientists from the University of Utah and a collaborator from University of California, Los Angeles, to research one of the biggest hurdles to quantum computing—the quantum logic units, or “qubits,” that carry information. The award is one of 19 Quantum Idea Incubator grants totaling $32 million funded this year as part of the National Science Foundation’s (NSF) Quantum Leap, one of NSF’s “10 Big Ideas” that represent bold, long-term research ideas at the cutting-edge of science and engineering.
The U-led project, “Quantum Devices with Majorana Fermions in High-Quality Three-Dimensional Topological Insulator Heterostructures,” was funded through an initiative called the Quantum Idea Incubator for Transformational Advances in Quantum Systems (QII – TAQS). QII – TAQS supports interdisciplinary teams that will explore innovative, transformative ideas for quantum science and engineering.
During his Ph.D. studies in the Department of Metallurgical Engineering at the University of Utah, Dr. Milan Stika studied molten salt electrochemistry under Prof. Michael Simpson. They worked on methods for measuring concentrations of actinides in molten salts used for applications such as nuclear reactors and nuclear fuel reprocessing. After a brief stint working for Flibe Energy on development of molten salt fueled nuclear reactors, Milan now works at Niowave, Inc., a company that produces radioisotopes used for medical diagnostics and cancer treatment. The company has a great team of accelerator physicists, nuclear engineers, and radiochemists supporting its mission. As a radiochemist, Milan works on projects that deal with separation of individual radioactive elements.
Niowave irradiates uranium targets to induce fission which creates a variety of useful fission products. The target is then dissolved so that fission products like molybdenum-99 can be harvested. Uranium is first pulled away from the rest of the elements using solvent extraction. It is then recycled into a new target. The elements useful for medical applications are then separated from each other using ion exchange resins and other methods.
Niowave also irradiates radium targets to produce actinium-225, a useful medical isotope along with other alpha emitters for targeted alpha therapy. Actinium is separated from radium and other products of the radium decay chain. Niowave is currently the only US private company producing actinium-225.
According to Milan, “the Department of Metallurgical Engineering was instrumental in helping me prepare for this exciting job in the nuclear sector by offering relevant coursework, networking opportunities, and advisor guidance.”
The University of Utah Department of Materials Science and Engineering is proud to announce that associate professor Taylor Sparks has been chosen to be a speaker at this year’s TEDxSaltLakeCity event on Sept. 21 at Kingsbury Hall on the university campus in Salt Lake City.
Sparks, whose research is focused on new materials for energy applications such as batteries, thermoelectrics, thermal barrier coatings and more, will be speaking on materials informatics, the process of using big data and machine learning to help researchers solve materials science challenges. The talk, titled “Striking a New Balance in Materials Discovery,” will dive into about how scientists can leverage information stored in materials data and compare that to how they traditionally discover new materials, which can largely be from trial-and-error.
TEDxSaltLake City describes itself as the “Wasatch Front’s leading platform for citizens to present and explore their ideas, stories, and creative solutions.” This year’s lineup will include 14 speakers and six musical acts.
