Dr. Bedrov and SMRC discover new liquid phase

Research activities in the MRSEC Soft Materials Research Center (SMRC) that includes molecular simulation group of Prof. Bedrov have discovered an elusive phase of matter, first proposed more than 100 years ago and sought after ever since. The “ferroelectric nematic” phase of liquid crystal has been described in recent study published in the Proceedings of the National Academy of Sciences (PNAS 2020 117, 14021-14031; https://doi.org/10.1073/pnas.2002290117). The discovery opens a door to a new universe of materials.

Nematic liquid crystals have been a hot topic in materials research since the 1970s. These materials exhibit a curious mix of fluid- and solid-like behaviors, which allow them to control light and have been extensively used in liquid crystal displays (LCDs) in many laptops, TVs and cellphones. The nematic liquid crystals like dropping a handful of pins on a table. The pins in this case are rod-shaped molecules that are “polar”—with heads that carry, say, a positive charge and tails that are negatively charged. In a traditional nematic liquid crystal, half of the pins point up and the other half point down, with the direction chosen at random. A ferroelectric nematic liquid crystal phase, however, patches or “domains” form in the sample in which the molecules all point in the same direction, either up or down, and therefore creating a material with polar ordering.

Debye and Born first suggested in the 1910s that, if you designed a liquid crystal correctly, its molecules could spontaneously fall into a polar ordered state. In the decades since, however, scientists struggled to find a liquid crystal phase that behaved in the same way. That is, until MRSEC researchers began examining RM734, an organic molecule created by a group of British scientists several years ago. That same British group, plus a second team of Slovenian scientists, reported that RM734 exhibited a conventional nematic liquid crystal phase at higher temperatures. At lower temperatures, another unusual phase appeared. When the MRSEC team tried to observe that strange phase under the microscope they noticed something new. Under a weak electric field, this phase of RM734 was 100 to 1,000 times more responsive to electric fields than the usual nematic liquid crystals and the molecules are nearly all pointing in the same direction.

However, experimentally it is hard to zoom down to molecular scale and understand why and how these RM734 molecules were achieving such collective behavior. This is where atomistic molecular dynamics simulations conducted by Dengpan Dong and Xiaoyu Wei from Prof. Bedrov group allowed to gain atomic scale understanding. First, the simulations were able to confirm that aligning all RM734 molecules in the same direction is energetically more favorable than to have conventional random alignment of molecular dipoles. Second, detail analysis of structural and orientational correlations obtained from simulations identified key groups and intermolecular interactions that stabilize the ferroelectric nematic phase. Using these tools Bedrov’s group currently explores other chemical structures that can lead to a similar behavior.

Discovery of this new liquid crystal material starts a new chapter in condensed-matter physics and could open up a wealth of technological innovations—from new types of display screens to reimagined computer memory. Within couple days of publication, the manuscript got a world-wide attention and was picked up by more than 25 news outlets around the world.

GERALD STRINGFELLOW’S BRIGHT IDEA

The National Academy of Inventors has released a new video about the legacy of Gerald Stringfellow, University of Utah Distinguished Professor of both electrical and computer engineering and materials science and engineering.

The new video, “From Campus to Commerce,” profiles Stringfellow’s contributions to the development of light-emitting diodes, a technology that would benefit everything that uses LEDs from traffic lights to computer monitors.

Stringfellow developed a process called organometallic vapor-phase epitaxy for the growth of new semiconductor alloys in which aluminum, gallium, indium and phosphorous are deposited on a substrate to create red, orange, yellow and green LED crystals. This led to better handheld calculators that used red LEDs for the display. Stringfellow took his research to the University of Utah where he was hired as a professor in 1980. He made major conceptual advances in the field and would later publish a book on the process that has now become the bible for the science of growing LED crystals.

Two MSE Students Receive Prestigious DOE Graduate Fellowships

The Department of Materials Science & Engineering is proud to announce that two of its graduate students, Jarom Chamberlain and Matt Newton, have been selected by the U.S. Department of Energy (DOE) to receive prestigious three year Nuclear Energy University Program (NEUP) fellowships in the amount of $161,000 each. Both students are in Prof. Michael Simpson’s group, working towards graduate degrees in metallurgical engineering. They both earned B.S. degrees in metallurgical engineering from the University of Utah.

Only 34 NEUP graduate fellowships were awarded this year for the entire country, so it is a remarkable testament of the quality of our students, department, and research that two awards were made to students at the University of Utah. Jarom and Matt will continue their work studying molten salt based processes in support of advanced nuclear energy in Prof. Simpson’s lab.

Since 2009, DOE has awarded close to 800 scholarships and fellowships totaling approximately $44 million to students pursuing nuclear energy-related degrees. Ninety-three percent of students who have completed nuclear energy-related fellowships have either continued to advance their education in nuclear energy or have obtained careers at DOE’s national laboratories, other government agencies, academic institutions, or private companies. Nine former fellowship winners are now university professors engaged in nuclear energy-related research, and one was competitively awarded an Office of Nuclear Energy research and development award in FY 2019.

Undergraduate Tristan Lundgren presents at SME Conference

As an undergraduate researcher, my focus has been on identifying efficiency issues related to a critical step of the gold mining processes. The Society for Mining, Metallurgy, and Exploration hosts an annual conference with an undergraduate research poster competition for entries related to mineral processing. With the generous assistance of the Crus Scholar program, I had the opportunity to attend and present at this year’s SME Expo in Phoenix, Arizona.

Over my three days at the conference, I attended a number of technical sessions where I learned about contemporary research endeavors going on in the fields of mining and metallurgy. In addition, I got to bounce questions given to me by my classwork and research off senior engineers and administrators of huge companies like FLSmidth, Newmont, and Freeport-McMoran. During my presentation, I was approached by curious industry professionals who were genuinely interested in the work I’ve been doing, and I ultimately won second place in the student poster contest.

My experiences at the conference will stick with me as I finish my degree and transition into the field. I learned and networked more than I’ve ever had the opportunity to do before, and I’m already putting those ideas and connections to use. I’m extraordinarily grateful to the Crus Scholar program for their assistance in opening new doors to my future by sponsoring my student research and travel for this event. I look forward to continuing my work and will make a point to attend SME 2021!

Discover the materials of the future … in 30 seconds or less

Since the dawn of history, the materials available to man have defined the very substance of society. The Stone Age gave way to the Bronze Age and eventually to the Iron and Steel Ages. We now enter the Information Age where technologists must balance a dynamic harmony between traditional approaches and transformational new tools. In this fascinating talk, Dr. Taylor Sparks will explain how he is working to reduce the trial and error of new materials discovery.

Dr. Taylor Sparks is an Associate Professor of Materials Science and Engineering at the University of Utah. He is originally from Utah and an alumni of the department he now teaches in. He did his MS in Materials at UCSB and his PhD in Applied Physics at Harvard University and then did a postdoc in the Materials Research Laboratory at UCSB. He is currently the Director of the Materials Characterization Lab at the University of Utah and teaches classes on ceramics, materials science, characterization, and technology commercialization.

His current research centers on the discovery, synthesis, characterization, and properties of new materials for energy applications. He is a pioneer in the emerging field of materials informatics whereby big data, data mining, and machine learning are leveraged to solve challenges in materials science. When he’s not in the lab you can find him running his podcast “Materialism” or canyoneering with his 3 kids in southern Utah. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

Ebrahiminia awarded second place at the Lithium Ion Batteries Symposium

The 236th Electrochemical Society meeting was held in Atlanta during the week of October 13-17, 2019. Mahsa Ebrahiminia, an MSE Ph.D. student from Dr. Dmitry Bedrov group, presented her latest work on transport and mechanical properties of model solid electrolyte interphases (SEI) that she studied using atomistic molecular dynamics simulations and was awarded the second place at the Lithium Ion Batteries Symposium.

SEI is one of the key components in the Li-ion batteries that, on the one hand, protects electrolytes from electrochemical decomposition and suppresses the growth of Li dendrites, but on the other hand, creates additional resistance for Li-ion transport between electrodes. Mahsa’s simulations provide a molecular scale insight into mechanisms of Li-ion transport and structure-property relationships that hard to obtain from experiments but are badly needed in order to design new materials for next generation of batteries.

Congratulations Mahsa!

Liu, Sparks receive Quantum Computing Grant

The National Science Foundation has awarded $1,635,591 to scientists from the University of Utah and a collaborator from University of California, Los Angeles, to research one of the biggest hurdles to quantum computing—the quantum logic units, or “qubits,” that carry information. The award is one of 19 Quantum Idea Incubator grants totaling $32 million funded this year as part of the National Science Foundation’s (NSF) Quantum Leap, one of NSF’s “10 Big Ideas” that represent bold, long-term research ideas at the cutting-edge of science and engineering.

The U-led project, “Quantum Devices with Majorana Fermions in High-Quality Three-Dimensional Topological Insulator Heterostructures,” was funded through an initiative called the Quantum Idea Incubator for Transformational Advances in Quantum Systems (QII – TAQS). QII – TAQS supports interdisciplinary teams that will explore innovative, transformative ideas for quantum science and engineering.
