Yunlong Jin wins Best Poster Award at International Conference
Yunlong Jin, a Ph.D. student from Prof. David J. Sellmyer’s research group, won the Best Poster Award in 62nd International Conference on Magnetism and Magnetic Materials in Pittsburgh Nov. 6-10, 2017. Yunlong presented an unexpected large perpendicular magnetic anisotropy (PMA) in the epitaxial thin films of half-metallic full-Heusler Co2TiSi films. The experimental results show the potential of this material for spin valves or magnetic tunnel junctions as high-performance magnetic memory elements such as spin-transfer torque magnetoresistive RAM (ST-MRAM or STT-MRAM) as an alternative or a replacement to NOR flash. STT-MRAM uses the magnetism of electron spin to provide non-volatile properties in chips. Besides, it combines the speed of SRAM, the non-volatility of flash and virtually unlimited endurance. The half-metallic Co2TiSi with theoretical 100% spin polarization is ideal to generate the spin-polarized current to force a change of magnetization. PMA will increase the areal density of chips compared to in-plane magnetic anisotropy. This research is supported by NSF-DMREF: SusChEM (1436385), NSF-NNCI (1542182), and NCMN.

David Berkowitz and colleagues have synthesized a new class of amino acid that can inactivate vitamin B6-fueled enzymes, or PLP enzymes, which are associated with a range of health issues, including Parkinson’s disease and epilepsy. (11/7/17)
Alexander Sinitskii and colleagues have developed a new form of nano-ribbon made from graphene that, when integrated into the circuitry of a gas sensor, responded about 100 times more sensitively to molecules than sensors with even the best-performing carbon-based materials. (10/20/17)
Xiao Cheng Zeng and colleagues have found that ice forms differently on absorbent vs. water-repellent surfaces. Ice that forms on the latter will freeze upward, with only a small portion of the base sticking to the surface, making it easier to remove. (10/18/17)
Sangjin Ryu will discuss the aerodynamics of the many flying machines featured in Hayao Miyazaki’s popular anime movies. The talk will take place on October 18 at 7 p.m. in the Adele Hall Learning Commons. (10/10/17)
Angela Pannier has received an NIH New Innovator Award to develop novel methods that improve the use of adult stem cells in gene therapy. Pannier is investigating nonviral delivery methods to introduce therapeutic genes into stem cells and how to improve the gene uptake of these methods. (10/5/17)
