Hongyou Fan’s use of pressure brings forth new materials and accolades
Sandia researcher Hongyou Fan has been awarded the prestigious 2024 Materials Research Society’s MRS Medal, recognizing his innovative approach to synthesizing nanomaterials using pressure instead of traditional chemical solutions. The MRS Medal is the society’s highest accolade, celebrating significant advances expected to greatly impact progress in materials science.
Hongyou’s work is described as “pioneering pressure-induced nanomaterial synthesis and characterization for materials exploration and discovery.”
“Using pressure has enabled us to form novel nanomaterial configurations with chemical and physical properties that weren’t achievable through conventional methods, resulting in three patents,” he said. “Depending on the applied pressure and starting materials, we have successfully fabricated a variety of metal, semiconductor and magnetic nanostructures and organic polymers with unique architectures and properties.”
A key aspect of Hongyou’s research involved using Sandia’s pulsed power facility to scale up the intensity of the synthesis process. This allowed his team to study material behavior under dynamic conditions. It led to the development of a high-throughput fabrication process using dynamic electromagnetic forces at ultra-short nanosecond timescales — a first in the field, he said.
“Our fundamental work focused on utilizing diamond anvil cells to address scientific questions, demonstrate the fabrication of new materials, and explore novel structures and properties. This approach, while highly effective for fundamental studies, was limited to small sample sizes.”
Using pulsed power provided significantly greater energy. “It enabled the fabrication of much larger samples and achieved the necessary pressures within nanoseconds — a dramatic improvement over current imprinting or embossing fabrication methods, which operate on time scales of seconds to minutes.
“This work underscores the significant value and impact of the outcomes resulting from the DOE Office of Science’s investments in national security,” Hongyou said. He also acknowledged the support from Sandia’s Laboratory Directed Research and Development program.
Recognizing a legacy of achievement
Over the past 20 years, Hongyou has received nearly one award each year for his contributions to science. In addition to the MRS Medal, he has been named a fellow of the American Physical Society, the American Chemical Society and the Materials Research Society. He received the MRS Fred Kavli Distinguished Lectureship in Nanoscience in 2015 and has been recognized for his mentorship of graduate students.
His accolades include Sandia’s Laboratory Directed Research and Development Award for Excellence in 2007, six R&D 100 Awards for innovative technologies from 2007 to 2022 and the Asian American Engineer of the Year Award in 2012. Recently, the New Mexico Legislature honored him for his scientific and entrepreneurial contributions.
