REMINDER: BNC Faculty Seminar Tomorrow, 10/24 @ 12:00pm (Lunch Provided) in BRK 2001 – Presenter is Prof. Miko Cakmak Dear all, The next BNC Faculty Seminar will be tomorrow Thursday, 10/24 @ 12pm (lunch provided) in BRK 2001. Professor Miko Cakmak will be presenting. Miko Cakmak<https://www.purdue.edu/discoverypark/birck/directory/profile.php?resource_i…>, Reilly Professor of Materials and Mechanical Engineering will present a brief overview of his work on flexible electronics using Roll to Roll manufacturing for the first half then the remainder will be open for questions and high-level discussion of collaboration opportunities that can lead to future center of excellence and/or also brainstorm about a shared vision for Birck. Field Assisted "Z" orientation of Nanophases to Produce Thickness Functionalized films For Flexible Electronics using a New Roll to Roll manufacturing Platform Electric1,2, Magnetic3, and Thermal gradient5,6 fields are three important methods used in Field Assisted Self Assembly (FASA) of polymer blends, block copolymers, liquid crystals and polymer nanocomposites. These assisted assembly techniques have been used in laboratory scale, but for potential applications such as flexible electronics7, membranes8, supercapacitors, fuel cells, photovoltaic’s etc. a large scale manufacturing platform is needed. We introduce a novel roll to roll process developed in our laboratories to achieve "Z-direction" alignment of nanostructural units. A 40ft line was designed which uses a casting system to deposit desired thickness of liquid such as a monomer ,polymer solution as well as melt up to 6" wide on a flexible substrate. The substrate is then carried to an electric field application zone which consists of temperature controlled opposing roll to roll electrodes. The electric field applied can be a DC, AC or a biased AC, hence using the various fields we can maximize the orientation by increasing the dielectric contrast between the particles and the matrix. [MicroCT of 100micrometer thick film with Z aligned Nickel nanoparticle column forest]If orientation and self-assembly through magnetic field is desired, the second tool located downstream is activated. This electromagnet is capable of applying magnetic fields up to 2.2 T to the material supported by a flexible substrate through the opposing poles. This line also contains a movable UV lamp which can be used to freeze the structure of required morphology using photocurable resin after electric field or magnetic field application zones. Electric and magnetic field alignment of particles and polymer chains is studied through real time birefringence measurement, to determine various parameters effecting the orientation of particles/phases inside a polymeric film under the magnetic or electric field. The birefringence system is based on the solution drying process developed in our lab9. In this talk, we will review our recent results on the use of this machine to produce Z-( thickness direction) functional films for capacitors, piezoelectric sensors, nanogenerators and transparent audio speakers10, and piezoresistive 11,12 films.

REMINDER: BNC Distinguished Seminar: Lon Bell, Thurs., Oct. 24th @ 11am in MRGN 121
by Turner, Jaime J 23 Oct '19

23 Oct '19

Dear Colleagues: We invite you to join us for Lon Bell's talk Thursday morning. This is the first in a series of talks about thermoelectrics. The next talk will be by Arun Majumdar on Nov. 21. The potentially transformative possibilities of thermoelectric technologies have long been understood, and over the past two decades, the thermoelectric material figure of merit has been increased substantially, but the promise of widely used commercial thermoelectric technologies has not been realized. Fresh perspectives from people outside of the thermoelectric research community are needed. For those of you looking for an introduction to thermoelectric science and systems, we have prepared a set of tutorials that you can find here: https://nanohub.org/groups/needus/taking_stock_of_thermoelectrics We hope that you will be part of the yearlong discussion that Lon Bell's talk will kick off on Thursday. -Mark and Ali [cid:image006.jpg@01D58994.3C5B5000] Opportunities, limitations and challenges to the broad commercialization of Thermoelectric technology Lon Bell CEO Ideal Power Inc. and Co-founder Gentherm and CALSTART Thursday, October 24, 2019 11:00am in MRGN 121 Abstract: Thermoelectric systems hold the promise of solid state heating, cooling an electric power generation without any greenhouse gas emissions or mechanical moving parts. Despite these very attractive features the technology has not been broadly adopted. This talk explores the state of thermoelectrics in light of materials and systems currently available, material properties, design and usage criteria and concludes with prospects for future broader commercialization. Bio: Currently, Dr. Bell is engaged with several emerging, technology driven companies that are characterized by the potential to have global economic impact, address long term societal needs and create strong IP positions. Bell is also a Chair of the External Advisory Board for the California Institute of Technology's Department of Mechanical and Civil Engineering. Bell founded Amerigon in 1991 (now Gentherm, NASDAQ: THRM). Gentherm is a $1B global leader in supplying high quality thermal management products to the automotive and commercial markets. Gentherm's automotive products include climate seats that provide both heating and cooling, EV battery thermal management systems, heated steering wheels, and heated and cooled storage bins. In 1991, Bell was a cofounder of CALSTART and its first president. CALSTART is a California based non-profit member-supported organization of more than 140 firms, fleets and agencies dedicated to supporting a growing high-tech, clean transportation industry with goals to help clean the air, create jobs, cut imported oil and reduce global warming emissions. As a founder and its first president, Bell led CALSTART's formation and initiated the process of transferring green aerospace technologies into the transportation sector. Bell served as a member of the Scientific Advisory Board at Michigan State University's Energy Frontier Research Center, a multi-university consortium conducting fundamental research in solid state energy conversion technologies. He served in a similar role for the University of California at Santa Barbara's Institute for Energy Efficiency. He has authored more than 40 publications in the areas of thermodynamics of thermoelectric systems, automotive crash sensors, and other electronic and electromechanical devices. He has been granted over 100 patents for his inventions. Five clusters of Bell's inventions have gone into mass production and dominated their target markets, generating over two billion US Dollars in sales. Bell received a bachelor's degree in Mathematics in 1962, a Master's degree in Rocket Propulsion in 1963, and a Ph.D. in Mechanical Engineering in 1968, all from the California Institute of Technology.

Professor Tongcang Li will be our first presenter for the Fall Semester Series. Tongcang Li<http://www.physics.purdue.edu/people/faculty/tcli.php>, Assistant Professor of Physics and Astronomy and Electrical and Computer Engineering will present a brief overview of his work on precision measurements and quantum sensing for the first half then the remainder will be open for questions and high-level discussion of collaboration opportunities that can lead to future center of excellence and/or also brainstorm about a shared vision for Birck. Precision measurements and quantum sensing with optomechanical systems and quantum emitters I will give a brief overview of our works on precision measurements and quantum sensing. In 2018, we optically levitated a nanodumbbell and drove it to rotate beyond 60 billion revolutions per minute, which was the fastest nanorotor in the world. This work was selected as one of the APS Physics top 10 “Highlights of the Year” of 2018 by the American Physical Society. With an optically levitated nanoparticle, we developed the world’s most sensitive torque detector and measured a torque as small as 10-27 Nm, which is several orders of magnitudes smaller than the former world record. Besides, we have built a dual-cantilever atomic force microscope (AFM) in vacuum and measured the Casimir force. We also used diamond nitrogen-vacancy centers for quantum sensing of magnetic field, temperature, and beyond. We have collaborated with colleagues in biomedical engineering and developed the axial plane single-molecule super-resolution microscopy.

FW: Distinguished Seminar by Sayeef Salahuddin of UC Berkeley
by Turner, Jaime J 14 Oct '19

14 Oct '19

---------- Forwarded message --------- Date: 10:30 AM, Thursday, October 17, 2019 Location: WANG Hall Room 1004 Distinguished Seminar Negative Capacitance Professor Sayeef Salahuddin University of California, Berkeley The physics of ordered and correlated systems allows for fundamental improvement of energy consumption, going beyond what is possible with conventional materials. One such example is the class of materials with polar distortion such as a (anti)ferroelectric, where thermodynamics dictate that charge can be switched with much lower energy compared to conventional dielectrics. In these materials the internal order leads to a state of negative capacitance, which results in a boost of internal electric fields and charge. This boost could be exploited for reducing energy dissipation in electronics. In this talk, I shall discuss our current understanding of negative capacitance derived from experimental demonstration of steady state negative capacitance, which allows one to access an otherwise forbidden part of the energy landscape in ferroelectric materials. We shall further discuss the integration of negative capacitance into advanced transistors, and its potential impact on next generation computing hardware. S. Salahuddin is the TSMC Distinguished Professor of Electrical Engineering and Computer Sciences at the University of California Berkeley. His work has focused mostly on conceptualization and exploration of novel device physics for low power electronic and spintronic devices. Salahuddin has received the Presidential Early Career Award for Scientist and Engineers (PECASE). Salahuddin also received a number of other awards including the NSF CAREER award, the IEEE Nanotechnology Early Career Award, the Young Investigator Awards from (AFOSR) and (ARO), and the IEEE George E Smith Award. Salahuddin is a co-director of the Berkeley Device Modeling Center (BDMC) and Berkeley Center for Negative Capacitance Transistors (BCNCT). Salahuddin is also a co-director of ASCENT, one of the six centers of the JUMP initiative sponsored by SRC/DARPA. He served on the editorial board of IEEE Electron Devices Letters (2013-16) and was the chair the IEEE Electron Devices Society committee on Nanotechnology (2014-16). Salahuddin is a Fellow of the IEEE and the APS.
