R. Lee Leonard and Jacqueline A. Johnson recently received complimentary copies of The Springer Handbook of Glass from Springer International Publishing. The handbook, edited by J. David Musgraves, Juejun Hu, Juejun, and Laurent Calvez, covers the current understanding of glass materials. Each chapter is devoted to a particular topic relating to glass and is written by an expert in the field.
Copies were sent to Leonard and Johnson due to their contribution, the chapter “Scintillator Glasses”. Scintillators are materials that spontaneously emit light at wavelengths within or near the visible region of the electromagnetic spectrum upon exposure to ionizing radiation. Their chapter introduces the reader to scintillator glasses and examines the basic advantages and disadvantages of glasses in comparison to other scintillator materials. The many varied applications of scintillator glasses including radiation detection, radiography, scanning electron microscopy, and neutron diffraction. “Johnson and I are very excited to be a part of this extraordinary project.” Leonard said of the handbook.
Both Leonard and Johnson are members of the faculty at the University of Tennessee Space Institute, located in Tullahoma, Tennessee in the Mechanical, Aerospace, and Biomedical Engineering Department. The are both part of the BEAMS (Biomedical Engineering and Material Science) research group, which is led by Johnson. “We are living in a glass age and this will be the seminal book on glass for years to come.” said Johnson.
Leonard received his Ph.D. in Biomedical Engineering from the University of Tennessee Knoxville (UT) in the summer of 2015 and became a faculty member of the UT Department of Mechanical, Aerospace, and Biomedical Engineering later that year. Leonard also holds an M.S. degree in Materials Science and Engineering (2010) from UT and a B.S. in Mechanical Engineering (1995) from Tennessee Technological University. He is a member of the American Ceramic Society and has served as a reviewer for the National Science Foundation on multiple occasions. Prior to joining UTSI in early 2009, Leonard worked for twelve years as a project and tooling engineer at Walker Die Casting, Inc., located in his hometown of Lewisburg, Tennessee.
Johnson completed her doctorate in solid state physics in the research area of magnetic phase transitions at the University of Liverpool in 1985. She transitioned to working on glass materials after being approached by Pilkington Glass to solve technical problems. She was a Professor in Liverpool until 1995 when she joined Argonne National Laboratory in the United States, where she was introduced to solving the structure of amorphous materials using neutron scattering. After a 2-year period in administration she returned to research to develop a new mammography system using a glass-ceramic plate. In 2007, Johnson returned to academia at the University of Tennessee Space Institute and continues to synthesize and characterize glasses, glass ceramics and nanomaterials pertaining to medical devices, non-destructive evaluation and image enhancement.
