UNL's 2016 NCMN Graduate Research Fellows are Cheng Bi and Ivan Zhuravlev.
Cheng Bi is pursuing a Ph.D in the Department of Mechanical and Materials Engineering and is focused on perovskite solar cell research. He has helped develop: a novel two-step interdiffusion process to fabricate high quality perovskite film, a method to tune the bandgap of perovskite film, and a method to manipulate the grain growth of perovskite for highly efficient solar cells. Several papers have been published in high impact journals, with Cheng as first or co-first author including Nature Communications, Advanced Functional Materials, Energy and Environmental Science, Journal of Materials Chemistry A and Small. His career aspirations are to work in the semi-conductor or chemical industry or stay in academia researching thin film solar cell development.
Ivan Zhuravlev is a doctoral student in the Department of Physics and Astronomy. His research has consisted of phase transformations in confined nanosystems, investigation of anomalous temperature dependence of the magnetocrystalline anisotropy in magnetic materials, and electronic structure calculations of the concentration dependence of intrinsic magnetic properties in certain alloys. Ivan has had two research papers published, both as first author, one in Physical Review B and the other in Physical Review Letters. The results of some of his work were presented at the 2014 APS Meeting. After graduation he would like to continue research in computational materials science.
Alexey Lipatov, a doctoral student in chemistry, works in the development of novel materials by exploring combinations of materials to achieve functional heterostructures for application in electronics, sensors and data storage. His achievements include the development of a highly selective and sensitive graphene-based sensor, enhancement of on-off ratios in ferroelectric tunnel junctions, and the fabrication of novel hybrid structures. His papers in these areas have appeared in Nature Communication 2014, Applied Physics Letters 2014, Nanoscale 2013, and other peer-reviewed journals. Lipatov has made presentations at international conferences and American Physical Society (APS) national meetings, and has been a visiting researcher at the Polish Academy of Sciences in Wroclaw, Poland.
Yuchuan Shao is a Ph.D. candidate in Mechanical and Materials Engineering. Yuchuan’s interests center on ferroelectric polymers with solar cell thermal energy applications. His research has also focused on electronic characterization and hybrid organo-metal halide perovskite material for solar energy harvesting. The results of Shao’s work have been included in a recently filed patent and reported in high-profile journals such as Nature Materials, Nature Communication, Advanced Materials and Energy Environ. Sci. In 2012 he received UNL’s Outstanding Graduate Award and has been the recipient of various prestigious scholarships.
In 2014 the NCMN Graduate Research Fellows were Dimitry Papkov, Timothy Martin and Chieu Van Nguyen.
Timothy Martin, a Ph.D. candidate in Biomedical Engineering, served as a Combat Engineer in the United States Marine Corps from 2002 – May 2008. His B.S. Mechanical Engineering and B.S. Biomedical Engineering degrees serve as a strong foundation for his career aspirations in research and development of gene/drug biotechnologies. Martin’s graduate work has involved transferring DNA from one form of life to another and his interests focus on biotech applications in materials (e.g. biomaterials/tissue engineering) and nanomedicine (e.g. gene therapy, cancer research). His research has appeared in peer-reviewed journals including The Journal of Gene Medicine published in 2013.
Chieu Van Nguyen is a doctoral candidate in Chemical and Biomolecular Engineering. Nguyen’s interests center on material science, especially those that leverage unique phenomena of nanoparticles and polymers to solving challenges in life such as renewable energy and cancer treatment. His research involves designing an artificial tactile sensor on par with the human finger both in resolution and sensitivity. The device has shown to be a good tactile sensor and it’s performance is currently being assessed. He has made numerous presentations at the Materials Research Society and American Physical Society national conferences as well as published articles in the ACS Nano Letters and Nano.
Dimitry Papkov is a doctoral student in materials engineering. Papkov studies the control of nanofiber structure and properties on the individual fiber level. His dissertation research examines the size effects in mechanical properties of individual nanofibers and systematically addresses structure-property relations. His paper on polymer nanofibers was featured on the cover of ACS Nano and was chosen as a feature article in Nature, Nano Today, Materials Today and several other publications. Papkov has also received UNL’s 2013-2014 Milton E. Mohr Graduate Fellowship and the 2013 Wolford outstanding research assistant award.
