Recognizing First Physics Ph.D. Graduate, Jiyang Chen

It a pleasure to recognize to recognize Jiyang Chen's completion of his Ph.D. degree in Physics under the supervision of Dr. Thang Hoang. Jiyang Chen defended his thesis, "Silicon-Based Nanostructures: Growth and Characterizations of Si2Te3 Nanowires and Nanoplates" in April 2021. His work developed a comprehensive understanding of properties of Si2Te3 nanostructures and to provide useful information on using these new nanomaterials as building blocks for RRAM devices, optoelectronic, and chemical sensing. In particular, it was demonstrated that the switching behavior of the Si2Te3 nanomaterials exhibit promise for applications in the Random Access Memory devices, while the anisotropic optical behavior is relevant in polarized sensor applications. Jiyang has accepted an offer from the Bruker and  return to China, where he will work with various X-ray instrumentation that perform X-ray diffraction, and X-Ray fluorescence spectroscopy. His time and efforts at the University of Memphis have been greatly appreciated and he will be missed. Jiyang came to consider the people in the Department as a second family. He hopes to return to the United States in the future and would love to continue to support the Department of Physics and Materials Science at the University of Memphis in the future. On behalf of the Department of Physics and Materials Science, we wish Jiyang success in his future endeavours.

Remembering UofM Emeritus Professor Narahari Achar

It grieves us to announce that Professor Emeritus Narahari Achar passed away on 23 April 2021. Dr. Narahari Achar joined the Physics faculty at the University of Memphis in 1984. He had a broad research interests ranging from topics in the electric properties of materials to applied fractional calculus to ancient astronomy and published prolifically in these areas. His wise, encouraging words and affable demeanor benefited his colleagues and students at the University of Memphis. He will be greatly missed.

We would invite you to visit Dr. Achar's online memorial, which is a testament to the positive impact his life had on faculty, staff, students--all those who had the pleasure of knowing him. The slide show below is offered in tribute to him.

UofM Professor's Temperature Sensing Probe to be Tested in Space, currently on International Space Station

Dr. Firouzeh Sabri's research group at the UofM has been working on advancing the application of phosphor based temperature measurements to space. This is a precise and low-cost technique for rapid temperature measurement over the range of 0°C to 1,200° C.  Nevertheless, materials outside of the protection of Earth's atmosphere must be resistant to the extreme temperatures and radiation of space, and thus they are now being tested in this environment on board the ISS. Results from this project will shed light on the radiation tolerance of phosphor powders and composites, providing critical information on the stability of the temperature-dependent properties of phosphor. This experiment will aid in determining the feasibility of using phosphor composite sensors for temperature measurements relevant to the healthcare, petroleum, and aerospace industries.  More information is available here

Assistant Professor leads two JWST studies of the inner workings of giant black holes 

Dr. Francisco Muller Sanchez is the PI of two successful James Webb Space Telescope proposals that will characterize the environments around supermassive black holes. The James Webb Space Telescope will be the world's premier space science observatory when it launches in 2021. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

NASA Office of STEM Engagement Grant awarded to Physics and Materials Science faculty member 

Dr. Firouzeh Sabri was awarded grant from NASA's Office of STEM Engagement (in collaboration with Dr. Stephanie Ivey) to convert content from her space sciences research into curriculum content for K-12. This will incorporate elements of Materials Physics at a suitable level for science classes. This work ties in nicely with Dr. Sabri's research in phosphor thermometry which was recently selected for investigation on board the International Space Station National Laboratory (ISSNL) and awarded a grant by ISSNL to conduct the work. Her project is currently scheduled for a February launch. Congratulations to Dr. Sabri and Dr. Ivey!

Physics and Materials Science faculty member among UofM faculty awarded a joint NSF ADVANCE grant

Dr. Firouzeh Sabri was awarded an NSF ADVANCE grant as a co-PrincipaI Investigator (co-PI) in collaboration with Dr. Esra Ozdenerol (PI) and fellow co-PIs Drs. Stephanie Ivey, Craig Steward, Amanda Rockinson-Szapkiw, Jacob Allen, and CAS Dean Abby Parrill-Baker. The purpose of the supported work is the fostering of gender equity in STEM throughout the UofM. Specifically, the intended outcome is an increasingly inclusive campus environment reflected in recruiting, hiring, retaining, and advancing of STEM women faculty, especially underrepresented minorities. Congratulations to Dr. Sabri and all the project PIs!

UofM Physics Student Participates in Prestigious Astronomy Summer Research Program

Savannah Woods

During summer 2020, student Savannah Woods participated in a summer research program at the National Radio Astronomy Observatory (NRAO) in Charlottesville, VA. Savannah--who is an undergraduate student at the UofM majoring in Physics with an Astronomy concentration--performed research at the NRAO studying Luminous InfraRed Galaxies (LIRGs). As their name suggests, these galaxies possess large luminosities in the infra-red portion of the electromagnetic spectrum due to enhanced star formation typically originating from galactic mergers. Savannah analyzed data from the Very Large Array (VLA) in New Mexico, the Atacama Large Millimeter Array (ALMA) in Chile, and Herschel (a space-based, infrared observatory). The experience provided the opportunity to work closely with leading astronomers from University of Virginia, UMass Amherst, Universidad Nacional Autonóma de Honduras, and Caltech among others, as well as to meet other undergraduate and graduate physics and astronomy students from other institutions. Savannah will be continuing her summer project as a student intern with the NRAO throughout the 2020-2021 academic year. Savannah's research talk is available here. For more information about Astronomy at the University of Memphis, please visit Dr. Muller Sanchez's page.
