[PAST EVENT] Rony Gustam Kalfarisi: Physics Dissertation Defense
Abstract:
My research interest revolved around studying local structures and dynamics of quadrupolar nuclei in materials using ssNMR spectroscopy. 7Li and 93Nb ssNMR magic angle spinning (MAS) spectra, acquired at 17.6 and 7.06 T, have been used to evaluate the structural and dynamical properties of cation-ordered microwave dielectric materials. Microwave dielectric materials are essential in the application of wireless telecommunication, biomedical engineering, food science and any other scientific and industrial implementations which use radio and microwave signals. The study of the local environment with respect to average structure, such as X-ray diffraction study, is essential for the better understanding of the correlations between structures and properties of these materials. The investigation for short and medium range of these materials can be performed with the use of ssNMR techniques.
Bio:
Rony Gustam Kalfarisi was born on August 15, 1985 in Medan, North Sumatra, Indonesia. He comes from a lower education family, his father graduated from technical school while his mother only graduated from elementary school. Since a young age, he was determined that one day he would study abroad. He realized that he was one step closer to his goal by getting a scholarship for his undergraduate study in physics at University of Pelita Harapan, Tangerang, Indonesia. His dream came true when he was accepted to continue his study in physics at William & Mary in Williamsburg, Virginia in 2010. In 2012, he joined Prof. Gina Hoatson and Dr. Robert Vold?s NMR spectroscopy group as an endeavor to develop his skill and interest in both physics and science.
