University of Utah materials science and engineering Distinguished Professor Anil Virkar, who has been with the U for more than 43 years, can add yet another honor to his list — he has been named a Fellow of the National Academy of Inventors (NAI).

“I’m extremely honored to be named to NAI. Having worked at Utah for 43 years with people like Prof. Ron Gordon and Prof. Ivan Cutler helped me get off the ground,” he said. “I’m also proud of the opportunities I have had here in Utah and the innovative research that is done here. Utah has been ahead of other states in the commercialization of research, which has helped me a lot as well.”

Virkar is one of 175 Fellows named to the academy from more than 135 institutions, according to an NAI announcement Tuesday, Dec. 13. He is the only one from the University of Utah to be named in this year’s group.

Selection to the academy is accorded to academic inventors who have demonstrated “a prolific spirit of innovation in creating or facilitating outstanding inventions that have made a tangible impact on quality of life, economic development, and the welfare of society,” according to NAI. The 2016 Fellows will be inducted April 6 as part of the Sixth Annual Conference of the National Academy of Inventors at the John F. Kennedy Presidential Library & Museum in Boston.

Virkar received his undergraduate degree at the Indian Institute of Technology in Mumbai and his Ph.D. at Northwestern University in 1973. Shortly after, he arrived at the University of Utah first as a post-doctoral fellow and then became professor where he has remained his entire career.

During his time here, Virkar has co-founded several companies, including Colorado-based Versa Power Systems and Materials and Systems Research, Inc., in Salt Lake City. Most recently, he co-founded Nano-Oxides, Inc., for the synthesis of nanosize oxide powders. His main research is focused on fuel cells, batteries, multi-species transport and the fabrication of ceramics.

Virkar also was elected to be Fellow of ASM International, the world’s largest association of materials-centric engineers and scientists, and he was recently named for the H. Kent Bowen Endowed Professorship in Materials Science and Engineering.

He joins University of Utah College of Engineering Dean Richard B. Brown and electrical and computer engineering professor Cynthia Furse, who also is the U’s associate vice president for research, as faculty from the College who have been named NAI Fellows.

With the election of the 2016 class there are now 757 NAI Fellows, representing 229 research universities and governmental and non-profit research institutes.

FT. DOUGLAS OFFICER’S CLUB, SALT LAKE CITY — On the evening of Thursday, April 7th, 2016, the Materials Science & Engineering Department assembled for the 16th annual MSE Senior Banquet & Poster Presentations at the Ft. Douglas Officer’s Club on the campus of the University of Utah in Salt Lake City.

The poster presentation portion of the evening is the fulfillment of the 18 graduating senior’s requirements for MSE 5098/5099. Over the past year students were broken up into eight groups and worked with faculty advisors to formulate their senior research and design projects. They reported their research and findings during the evenings festivities. 

The top three poster presentations were recoginized by the departments — first place was won by Jason Dalton and Garrett Meeks; second place was Carl Luft, Kyle Campbell and Zixiao Liu; and, third place was Brandon Day and Kristina Lundgren (see bar on left for project title information). All senior posters will be on display in the MSE Department for the following year. 

The program spent the evening honoring both Kristina Lundgren (BS ’16) and Megan Stephanz (BS/MS ’17) as the Outstanding Graduating Seniors of 2016. Typically the department honors one graduating senior, but the caliber of graduating seniors made it difficult to chose just one student to honor.

The 2017 Materials Science & Engineering Senior Banquet & Poster Presentation is slated for Friday, April 7, 2017, location TBA.

Alkane fuel is a key ingredient in combustible material such as gasoline, airplane fuel, oil — even a homemade bomb. Yet it’s difficult to detect and there are no portable scanners available that can sniff out the odorless and colorless vapor.

But University of Utah engineers have developed a new type of fiber material for a handheld scanner that can detect small traces of alkane fuel vapor, a valuable advancement that could be an early-warning signal for leaks in an oil pipeline, an airliner, or for locating a terrorist’s explosive.

Their discovery was published online Friday, March 25, in the American Chemical Society’s journal, ACS Sensors. The team is led by University of Utah materials science and engineering professor Ling Zang, who also is a faculty member with the Utah Science, Technology and Research (USTAR) economic development initiative.

Currently, there are no small, portable chemical sensors to detect alkane fuel vapor because it is not chemically reactive. The conventional way to detect it is with a large oven-sized instrument in a lab.

“It’s not mobile and very heavy,” Zang says of the larger instrument. “There’s no way it can be used in the field. Imagine trying to detect the leak from a gas valve or on the pipelines. You ought to have something portable.”

So Zang’s team developed a type of fiber composite that involves two nanofibers transferring electrons from one to the other.

“These are two materials that interact well together by having electrons transferring from one to another,” says Ben Bunes, a postdoctoral fellow in the University of Utah’s materials science and engineering department. “When an alkane is present, it sticks in between the two materials, blocking the electron transfer between the two nanofibers.”

That kind of interaction would then signal the detector that the alkane vapor is present.

SALT LAKE CITY — Materials Science & Engineering student, Jeffrey Copeland (B.S., ’17) was awarded a Governor’s Energy Leadership Scholars (GELS) award from the state of Utah. Copeland is a student in the Professor Taylor Sparks research group. 

Copeland will use his award to work along with group members — Max Gallant, Carina Hahn and Nic Flinner who founded Electrochrome LLC., to develop inexpensive films that can be applied to windows (see left bar for more information). 

One potential application for this technology are “smart windows” in residential and commercial buildings that can be programmed to reflect more sunlight to keep the interior cooler during hot times of the day. 

This is the third student that Dr. Sparks advises who has recieved this award. Leila Ghadbiega (Ph.D. candidate) and Matthew Judge (B.S., ’16) were receipents of the award for the 2014-15 academic year.

Congratulations Jeffrey and the Prof. Sparks research group!

University of Utah engineers have discovered a new kind of 2D semiconducting material for electronics that opens the door for much speedier computers and smartphones that also consume a lot less power.

The semiconductor, made of the elements tin and oxygen, or tin monoxide (SnO), is a layer of 2D material only one atom thick, allowing electrical charges to move through it much faster than conventional 3D materials such as silicon. This material could be used in transistors, the lifeblood of all electronic devices such as computer processors and graphics processors in desktop computers and mobile devices. The material was discovered by a team led by University of Utah materials science and engineering associate professor Ashutosh Tiwari. A paper describing the research was published online Monday, Feb. 15, in the journal, Advanced Electronic Materials. The paper, which also will be the cover story on the printed version of the journal, was co-authored by University of Utah materials science and engineering doctoral students K. J. Saji and Kun Tian, and Michael Snure of the Wright-Patterson Air Force Research Lab near Dayton, Ohio.

Transistors and other components used in electronic devices are currently made of 3D materials such as silicon and consist of multiple layers on a glass substrate. But the downside to 3D materials is that electrons bounce around inside the layers in all directions.

The benefit of 2D materials, which is an exciting new research field that has opened up only about five years ago, is that the material is made of one layer the thickness of just one or two atoms. Consequently, the electrons “can only move in one layer so it’s much faster,” says Tiwari.

While researchers in this field have recently discovered new types of 2D material such as graphene, molybdenun disulfide and borophene, they have been materials that only allow the movement of N-type, or negative, electrons. In order to create an electronic device, however, you need semiconductor material that allows the movement of both negative electrons and positive charges known as “holes.” The tin monoxide material discovered by Tiwari and his team is the first stable P-type 2D semiconductor material ever in existence.

“Now we have everything — we have P-type 2D semiconductors and N-type 2D semiconductors,” he says. “Now things will move forward much more quickly.”
