Thermoelectric Energy Conversion: Nov. 21 - 10 AM in PGSC
by Turner, Jaime J 15 Nov '19

15 Nov '19

--------------------------------------------------------------------------- Thermoelectric Energy Conversion: Science and Engineering Challenges and Opportunities Arun Majumdar Stanford University Thursday, November 21, 2019 10:00 am • Purdue Graduate Student Center (PGSC) Followed by a fireside chat with Ali Shakouri Abstract: The last 20 years have witnessed intense research focus on the science and engineering of solid-state thermoelectric materials, with the goal of achieving high ZT (~ 2-3) over a large temperature range and thus enabling commercial technology for waste heat recovery and cooling. While the scientific research has to led many fundamental insights about how to engineer the behavior of electrons and phonons, the promise of high ZT and widely-used commercial technology remains largely unfulfilled.For waste heat recovery, this is partly because the performance targets have been raised due to competition from increasingly lower cost of solar and wind electricity. However, with the phasing out of today’s refrigerants due to the Kigali amendment of the Montreal Protocol, cooling offers an enormous opportunity if high ZT materials can be developed for room temperature operation, and system-level costs can be reduced and performance increased. The increase of ZT at room temperature requires new mechanisms and science to engineer the electronic and phononic structure and transport. This talk will provide a viewpoint of these new scientific opportunities and challenges in the context of practical performance and cost metrics. It will also offer new approaches to manipulate entropy change in liquid media for the purpose of energy conversion. Bio: Dr. Arun Majumdar is the Jay Precourt Provostial Chair Professor at Stanford, and a faculty member in Mechanical Engineering and Materials Science and Engineering. He is co-director of the Precourt Institute for Energy, which integrates and coordinates research and education activities across all seven Schools and the Hoover Institution. Dr. Majumdar's current research focuses on electrochemical and thermochemical redox reactions that are fundamental to a sustainable energy future, multidimensional nanoscale imaging and microscopy, and a new effort to re-engineer the electricity grid using data science, including deep learning techniques. He was the founding director of ARPA-E before which he was the Almy & Agnes Maynard Chair Professor of Mechanical Engineering and Materials Science & Engineering at UC–Berkeley. Dr. Majumdar is a member of the National Academy of Engineering and the American Academy of Arts and Sciences.

BNC Seminar: Babak Anasori, Today Oct. 31st 12:00pm in BRK 2001

REMINDER: Today at 12:00pm in BRK 2001 ________________________________ BNC Seminar: Babak Anasori OCTOBER 31, 2019 12:00 PM - 1:00 PM BRK 2001 2D Transition Metal Carbides and Nitrides (MXenes): Advances, Challenges, and Opportunities Abstract: Two-dimensional (2D) transition metal carbides and nitrides, called MXenes, are becoming one of the largest family of 2D materials with more than thirty synthesized compositions [1]. MXenes have shown outstanding performance in many applications including energy storage, catalysis, electromagnetic interference shielding, wireless communication, water purification, sensors, reinforcement in composites, and biomedical applications. In MXenes, n+1 layers of an early transition metal (such as Ti, V, Nb, Ta, Mo, Cr) cover n layers of carbon or nitrogen (n = 1-3), such as Ti2C, Mo2C, Ti3C2, Ta4C3. These 2D metal carbide flakes are covered with surface terminations, such as hydroxyl, oxygen, or fluorine, which add hydrophilicity to MXene surfaces [2]. Most of the synthesized MXenes to date, have high electrical conductivities (e.g., ~10,000 S/cm for Ti3C2), and high elastic properties. For example, the measured Young's modulus of a Ti3C2 single flake is ~330 GPa, which is the highest among the values reported for other solution-processed 2D materials, including graphene oxide. MXene compositions can be further tuned by the formation of in-plane and out-of-plane atomic ordering when using two transition metals. For example, in Mo2TiC2 a layer of Ti atoms is sandwiched between two layers of Mo in a 2D carbide structure [3]. Such atomic orderings create a significant possibility of tunable 2D compositions, where properties, including electrical, electrochemical, and mechanical, can be tailored at the 2D level. In this talk, I will describe the advances and challenges in the synthesis and fundamental understating of MXenes with a focus on ordered double-transition metal MXenes and present an outlook for several opportunities in this large family of 2D materials. 1.

Bio: Babak Anasori is an Assistant Professor in the Department of Mechanical and Energy Engineering at Purdue School of Engineering and Technology in IUPUI. He received his PhD at Drexel University in 2014 in Materials Science and Engineering, the birth place of MXenes. Babak is one of the co-inventors of ordered double-transition metal MXenes, as a result of his postdoctoral research. His current research focuses on synthesis and characterizations of novel MXenes and their composites. He has co-authored over 100 refereed publications and has received several national and international awards for his research and artistic way of presenting science including NSF/Science Visualization Challenge in 2011 and 2013, Diamond ranking in ACerS Graduate Excellence in Materials Science (GEMS) in 2012, and Materials Research Society (MRS) Postdoctoral Award in 2016. Babak has originated and organized multiple international student competitions, including NanoArtography and Science in Video (SciVid) in the MRS Fall Meetings.
