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.

Hongyou Fan offers tools of success for other scientists

Early-career scientists often find it tough to get noticed in the competitive arena of scientific research. In a recent interview with Lab News, Hongyou Fan shared his insights on navigating these challenges and building a fulfilling research career.

Hongyou emphasizes the importance of tackling significant challenges. “Identify problems that matter,” he said. “Look for gaps in existing knowledge that haven’t been addressed yet.” By keeping an eye on emerging trends, researchers can pinpoint areas ripe for innovation.

For Hongyou, this meant diving deep into the mysteries of nanoparticles. “How closely can they approach each other? Can they make contact? What happens if they do?” These questions led to groundbreaking discoveries about nanoparticle behavior and the creation of a pressure-induced assembly method.

“Solving real-world problems often results in impactful outcomes like influential publications, patents or industrial applications,” he said.

In a profession where the pressure to publish can be intense, Hongyou champions quality over quantity. “Early in your career, it’s easy to feel the need to publish frequently, but focusing on groundbreaking work is far more rewarding,” he said. His first paper on high-pressure nanomaterials assembly took more than three years to publish but opened new research avenues and led to patented technologies.

Engaging with the scientific community is crucial, says Hongyou. Attending and presenting at conferences helps build a reputation and forge connections. “Conferences provide a platform to showcase your research and exchange ideas,” he said. He encourages researchers to present their work, even if it’s still in the early stages. Organizing symposiums on specific topics can boost visibility and establish researchers as thought leaders. “Facilitating knowledge sharing increases your profile and can lead to new collaborations,” he said. Networking at these events can pave the way for joint projects and co-authorships.

Hongyou also underscores the value of interdisciplinary collaboration. Working with experts from diverse fields can spark innovative solutions that might not emerge within a single discipline. His partnership with Sandia’s pulsed power team, for example, allowed them to explore ultrafast nanomaterials manufacturing — a breakthrough none could have achieved alone. “By leveraging each other’s strengths, we tackled complex problems more effectively,” he said.

Strategic partnerships with institutions that offer complementary resources can further boost research efforts. Hongyou’s collaboration with synchrotron teams accelerated their understanding of material structures under pressure, drawing greater attention to their work.

Persistence is key when facing setbacks, according to Hongyou. “Recognition and success don’t come easily or overnight,” he said. He recalled the challenges he faced, including multiple rejections before publishing his first papers. “Each setback taught us valuable lessons. Don’t be discouraged by early challenges; keep refining your approach,” he said.

Focusing on long-term goals is essential for building a successful research career, he added. “Successful careers are built over time through consistent effort and a willingness to learn from failures,” Hongyou said. “Patience combined with persistence ultimately leads to breakthroughs and recognition.”
