"[3] His next major project was research on heat transfer and the "development of a thin, evacuated, flat-panel thermal insulation for use in refrigerators, freezers, and other cooling devices.
Success—the reproducible synthesis of diamond in the GE lab with a “fair” understanding of the process—came in early 1955, and Strong’s name appears on the first patent and publications of the results.
Those achievements made it possible to experimentally investigate various properties—such as electrical and optical properties, heat conduction, and isotope effects—of nearly perfect diamond crystals.
"[6] In retirement, Strong, with other local physicists, participated in a program sponsored by Schenectady's Museum of Innovation and Science.
The program enabled schoolchildren to participate "in simple demonstrations of gravity, optics, magnetism, conservation of momentum, and other basic physical phenomena.
