Zak Fang Elected to Fellow in the National Academy of Inventors

December 8, 2017

zakDr. Zak Fang, professor in the Department of Metallurgical Engineering, was just elected to the rank of Fellow in the National Academy of Inventors (NAI). This honor 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. Congratulations Dr. Fang!



Undergraduate Student, Jake Salgado, Wins University Veteran of the Year

November 6, 2017

jake labSenior metallurgical engineering student, Jake Salgado, has been recognized this year as the University of Utah Veteran of the Year.  Jake will be given the award at the upcoming home football game against Washington St.  After graduating from Davis High School in Kaysville, Utah, Jake enlisted in the Army as an Infantryman in 2010. He graduated basic combat training and advanced individual training in 2011.  Later that year, he was deployed in Afghanistan for 10 months in support of Operation Enduring Freedom where he was a member of the Company Intelligence Support Team (CoIST). As a member of the CoIST, he worked closely with the Afghan military and police, interacted with the local Afghans to build relations in the community, and collected intelligence on enemy movements and activity.  As part of the effort to prevent the freedom of movement of enemy forces and provide security for the local populace, he and his unit conducted dangerous patrols almost every day of his deployment, and they frequently encountered enemy fire and improvised explosive devices.  After completing his service in 2013,  he returned to Utah and started his college studies at Weber State.  He transferred to University of Utah after learning about metallurgical engineering and the impact he could have on many different industries.  He has been working as a researcher for Prof. Raj Rajamani on his electrodynamic sorting project and is chairman of the department's Student Advisory Committee.  Jake has a 3.6 GPA and is on track to graduate in spring 2018.  The department is very proud of him and happy to learn of this most deserving recognition from the university. 

Prof. Free and Prof. Sarswat Receive DOE Nuclear Physics Grant

September 5, 2017

The U.S. Department of Energy's Office of Science recently awarded Prof. Mike Free and Prof. Prashant Sarswat a $289,000 grant to support research on separation of lithium isotopes.  Production of Li-7 is needed to support advanced nuclear energy systems such as molten salt fueled reactors and molten salt cooled reactors.  The conventional process for separating Li-7 from Li-6 involves a liquid extraction process featuring highly toxic mercury.  This process has been banned in the United States, and Li-7 currently used by the nuclear industry is obtained from China.  Prof. Free and Sarswat are developing a new Li isotope separation process that does not require the use of mercury and offers great promise to supply future demand for this isotope.

Prof. Fang's ARPE-E Funded Research in Spotlight

July 26, 2017

As part of ARPA-E’s METALS program, the Prof. Fang's group has developed dramatically simpler titanium (Ti) metal-from-ore extraction and metal-to-spherical power production processes.  Utah’s novel extraction process removes Ti metal from ore in a way that reduces cost, energy consumption, and emissions, and it has enabled a new means to produce high-quality spherical powders of Ti and Ti alloys, a high-value feedstock for 3D printing.

The Utah team is working with partners Boeing and Arconic to scale and validate their titanium separation and power production processes over the next two years. Utah has spun out a small company, FTP Manufacturing, to produce spherical powders in small batches for potential future customers to evaluate in their fabrication processes.

Students win prestigious DOE-Nuclear Energy awards

June 22, 2017

Silvia PadillaSilvia Padilla and Matthew Newton, seniors in the Department of Metallurgical Engineering, were awarded 1-year, $7500 scholarships from the U.S. Department of Energy's Integrated University Program administered by the Office of Nuclear Energy.  Silvia and Matt both are members of Prof. Simpson's resesarch group and work on projects related to nuclear material detection and separation. Adam Burak, a Ph.D. student in Prof. Simpson's group, was a winner of the 2017 Department of Energy Innovations in Nuclear Technology R&D competition.  The program is designed to award students for innovative nuclear technology relevant research as demonstrated through journal publications and conference presentations.  Adam was a winner of a $1500 prize in the category of students who attend universities with less than $600 million in 2016 R&D Expenditures.

Titanium powders produced by reducing TiO2 with magnesium in a hydrogen atmosphere

Dr. Zak Fang's research group recently received $3 million in funding to develop two process technologies for production of low-cost titanium powders, from the Advanced Research Projects Agency- Energy (ARPA-E) of the U.S. Department of Energy and its industrial partners. The first is Ti-6Al-4V spherical powder for 3D printing/additive manufacturing, and the second is commercially pure (CP) titanium powder.

This is a continuation of a project funded under ARPA-E's METALS program since 2013. The goal of the continuation project is to produce powders at a pilot scale and validate the technology for industrial applications. The patented processes use low-cost commercial TiO2 as the raw material, and magnesium to reduce TiO2 in a hydrogen atmosphere. The processes are relatively simple and promise drastically reduced cost of production for both CP-titanium and spherical Ti-6Al-4V powders.

The process is based on a patented de-oxygenation technology that relies on hydrogen to thermodynamically destabilize Ti-O solid solutions. It can produce titanium powder with extra-low oxygen content. Producing low-oxygen titanium alloy powder for additive manufacturing has been one of the major factors contributing to its high cost. The technology of this project could potentially disrupt the existing marketplace.

The team is led by Professor Z. Zak Fang. Boeing and Arconic Titanium Engineered Products are industrial partners.

Light-Emitting Diodes: From Bread to Bulbs

TVs, Christmas lights, and flashlights of the future could be lit up using our leftover bread crusts. That’s theLED finding of two University of Utah researchers searching for a more sustainable and less expensive way to make light-emitting diodes (LEDs).

LEDs have been a popular, more efficient alternative to fluorescent and incandescent bulbs for the past few decades. But LEDs are generally produced using quantum dots (QDs), tiny crystals that have luminescent properties. And many of these QDs are expensive to synthesize, as well as potentially harmful to dispose of. So some research over the past 10 years has focused on using carbon dots (CDs, or simply, QDs made of carbon) to create LEDs. Compared to other types of quantum dots, CDs have not only lower toxicity but also better biocompatibility, meaning they can be used in a broader variety of applications.

U Metallurgical Engineering Research Assistant Professor Prashant Sarswat and Professor Michael Free have now successfully turned food waste such as soft drinks and discarded pieces of bread and tortillas into CDs, and subsequently, LEDs. They found sucrose and D-fructose dissolved in soft drinks to be the most effective sources for production of CDs. Currently, one of the most common sources of QDs is cadmium selenide, a compound composed of two toxic elements, leading to concerns over toxic waste. Using food waste could not only be nontoxic but actually reduce the waste stream.

Free and Sarswat’s results were recently published in Physical Chemistry Chemical Physics, a journal of the Royal Society of Chemistry. Looking forward, the researchers hope to continue studying the LEDs produced from food waste for stability and long-term performance.
