ASU grad student wins Innovation Award for sustainable semiconductor coating process

School of Molecular Sciences PhD student Thu Thao Nguyen's method garners interest from government agencies, manufacturing corporations

May 4, 2022

Thu Thao Nguyen, an Arizona State University PhD student working with School of Molecular Sciences Associate Professor Ryan Trovitch, has developed a catalyst that provides a sustainable and efficient method to produce semiconductor coatings.

Because semiconductors are used in a wide range of electronics, her manganese-based catalyst has not only earned her the Innovation Award from the School of Molecular Sciences, but it has also garnered interest from government agencies and manufacturing corporations.

“Few chemists are able to redefine the applications of a reaction while immediately gaining the attention of government agencies and corporate partners,” Trovitch said. “Thao has been able to do just that. Her development of an earth-abundant metal catalyst for the synthesis of chemical vapor deposition precursors represents a significant improvement over current methods that rely on corrosive chlorosilanes and offers the world a sustainable route to semiconductor coatings, which can positively impact microelectronics and solar panel manufacturing.”

The award, which is supported through the ASU Foundation, is given annually to a graduate student for excellence in achieving the School of Molecular Sciences' mission of discovering molecular-level solutions to real-world challenges through the pursuit of methodology or development of research ideas or inventions.

“(The school) continues to be extremely grateful to Emeritus Professor William Glaunsinger and Lorna Glaunsinger for their continued support of this award, which provides our students with a unique opportunity and represents a concrete demonstration of support of the principle 'advancing research and discovery of public value' as given in the ASU Charter,” said Tijana Rajh, director of the School of Molecular Sciences.

Nguyen, in her fourth year of her PhD program, is grateful for receiving the Innovation Award, as well as the opportunities she has at ASU.

Born and raised in Hanoi, Vietnam, by her mother, Nguyen credits her mom for nurturing her curiosity and tenacity.

“My dad passed away when I was only 1 year old,” Nguyen said, “so my mother had to work really hard to make a living. We were very poor, but she never refused whenever I said that I wanted to learn something. She always encourages me to try my best and do what I want. Seeing how hard she works and all the difficulties she has been through motivates me to tackle any challenge and not to give up.

“Receiving the 2022 SMS Innovation Award lightens part of my financial burden and motivates me to focus more on research and the pursuit of my career as a chemist."

Nguyen earned her bachelor's degree in chemistry from the Hanoi University of Education, then worked as a high school teacher prior to starting her graduate degree at ASU in 2018.

“I like the fact that ASU supports and encourages graduate students to do science independently and utilize the facilities needed for our research,” Nguyen said. “The staff are super kind and are always willing to help us.”

Nguyen and Trovitch are currently working with ASU Skysong Innovations on the commercialization of her catalyst, which has been recently patented, and further study funded by a grant from the National Science Foundation.

“Thao has already synthesized several grams of her catalyst for industrial screening,” Trovitch said, “and her efforts are directly responsible for a National Science Foundation award that our group recently received. I was thrilled to hear that Thao was named the recipient of this year’s School of Molecular Sciences Innovation Award. She absolutely deserves it!”

“I think innovation is critical, especially in this time when we are facing many challenges in a wide range of fields, from new diseases to the hurdles of sustainable energy and environmental problems," Nguyen said. "Doing research is difficult; receiving this award encourages me to pursue my career as a scientist and find sustainable solutions that benefit the world.”

William Petuskey retires after distinguished four-decade career at ASU

“Bill played a vital role on Panch’sSethuraman “Panch” Panchanathan, who spent more than 20 years in leadership positions at Arizona State University, including service as executive vice president of ASU’s Knowledge Enterprise, and chief research and technology officer for ASU. He became director of the National Science Foundation in June 2020. team to advance the research mission of the university,” said Patrick Kenney, dean of The College of Liberal Arts and Sciences, Foundation Professor in the School of Politics and Global Studies and vice provost for Academic Enterprise Strategy. “In a fast-paced environment, he was thoughtful, thorough and found creative solutions to challenging implementation problems. Bill always worked collaboratively across the Knowledge Enterprise leadership, with deans, sponsors, directors, chairs and investigators. I learned a great deal from him in our time together in what was then called OKED.”

Praise for Petuskey comes from the sciences and humanities alike.

“Bill Petuskey is a scientist and a leader in scientific research and administration,” said Professor George Justice. “But I want to say that Bill Petuskey is also a thoughtful human being — and has been both a very strong mentor and a very good friend to me, an English professor and former dean of humanities, who worked alongside Bill in OKED as we tried to build research in ASU humanities. Although not a humanist, Bill Petuskey is a deeply humane person who always put the university, in all its various byways, first. It has been my privilege to know him and learn from him.”

The exciting journey

Petuskey grew up in Salt Lake City and received his Bachelor of Science from the University of Utah’s department of materials science and engineering in 1973.

In 1977, he received a Doctor of Science in ceramic science from Massachusetts Institute of Technology (MIT) and went on to conduct postdoctoral research at Leibniz University Hannover in Germany. Petuskey then joined the University of Illinois as an assistant professor of ceramic science.

In 1983, together with his wife, Karen, Petuskey moved to Arizona and what was then the department of chemistry at ASU. He had met School of Molecular Sciences Professor Alexandra Navrotsky as a graduate student at MIT, as well as professors LeRoy Eyring, Bruce Wagner and Michael O’Keeffe.

Only three years later in 1986, Petuskey was appointed assistant chair of space by Bill Glaunsinger (department of chemistry chair), and he oversaw the design and building of the Bateman Physical Sciences H wing.

Amidst various leadership roles came some exciting research advances: Petuskey, along with six other faculty, was awarded a large Materials Research Grant by the National Science Foundation (NSF), which became the Materials Research Science and Engineering Centers (MRSEC) and was funded by NSF for about 13 years.

During this time, several Science and Nature papers were published on new functional materials under extreme conditions of pressure, temperature and chemical environments.

Petuskey’s collaborators on this venture were professors Paul McMillan, Austen Angell, George Wolf, John Holloway, Michael O’Keeffe, Otto Sankey and, at the later stage, Omar Yaghi.

From 2002 to 2006 Petuskey was associate chair for what was then the department of chemistry and biochemistry (chaired by Bob Blankenship).

“Bill and I led the department from 2002 to 2006,” said Blankenship, a professor emeritus. “It was a time of great increase in student numbers and programs. We were always scrambling to have enough sections of freshman chemistry to meet the ever-increasing demand. At one point, we maxed out the facilities and proposed to the dean that we could offer evening sections. They were very reluctant to do this, but we persisted and they finally agreed. Just a year later, it was impossible to imagine not having the evening program.

“Bill was always great to work with. We came from opposite ends of the department, as he was from the materials/inorganic side and I was from the biochemistry side. But we complemented each other well, and that diversity in background and perspective greatly benefitted the department as it was growing extremely rapidly.”

From 2006 until 2012, Petuskey was the chair of the department of chemistry and biochemistry, assisted by two very able associate chairs, Jim Allen and Wilson Francisco.

This was also a time of huge growth for the department as they hired 13 new faculty in a two-year period. New degree programs were also initiated, including a Bachelor of Science in biochemistry (medicinal chemistry), which remains hugely popular to this day.

“The thing that was fun for me was just getting to know all the people,” Petuskey said. “The people I’ve met and worked with over the years have made all the difference. It was a social as well as research environment and intellectual enterprise. At each stage, the people I really wanted to work with were there.”

In 2009, together with engineering Professor James Adams, Petuskey started ASU’s School of Materials, increasing their ranking to No. 22 nationally. After three years, the school was absorbed into the School for Engineering of Matter, Transport and Energy.

From 2012 to 2016, Petuskey served as ASU’s associate vice president for science, engineering and technology when, among many advances, he supported ASU's compact X-ray free electron laser (a world first), which is housed in the Biodesign Institute. It will provide X-ray pulses so short that they outrun all X-ray damage processes. As a result, scientists can conduct novel science to explore the structure and dynamics of nature and materials as never before.

In 2016, there was a national program for new technologies to develop new materials in half the time for half the cost. Petuskey was appointed as director of the Advanced Materials Initiatives (AMI) in Knowledge Enterprise to help design approaches to scientific problems from a different direction. Starting with a significant problem and working backward to the important scientific ideas.

The Navrotsky Eyring Center for Materials of the Universe headed by Navrotsky and the grant from the NSF's Quantum Leap Challenge Institutes program headed by School of Molecular Sciences Professor Vladimiro Mujica would not be possible without the AMI.

Over his 39 years at ASU, William Petuskey has been a catalyst for growth and development for the School of Molecular Sciences and for the university as a whole.
