FW: Seminar 4/19 11AM BNC 1001 Seunghyun Baik
by Black, Nancy Lee 19 Apr '12

19 Apr '12

Professor Jong Hyun Choi will be hosting a seminar at Birck Nanotechnology Center today on April 19 at 11:00 AM for Seunghyun Baik from Sung Kyun University in Suwon, Korea. You are all invited to attend. Composite, Energy and Environmental Applications of Carbon Nanomaterials Seunghyun Baik sbaik(a)me.skku.ac.kr Department of Energy Science and School of Mechanical Engineering, Sungkyunkwan University, Suwon, Korea Carbon nanomaterials such as carbon nanotubes and graphene have received considerable attention due to their unique electrical and mechanical properties. This talk provides an overview of our lab's recent research activities in conductive composite, energy and environmental applications of carbon nanomaterials. Firstly, carbon nanotube-incorporated conductive composites have been of interest for decades. However, the poor contact interface hindered a dramatic increase in electrical conductivity for polymer matrix composites. Here we present highly conductive silver/epoxy pastes [1], metallic inks [2] and stretchable conductive films [3] by using micron-sized silver (Ag) flakes and a small amount of nanotubes functionalized with Ag nanoparticles. The one-dimensional, flexible and conductive nanotubes constructed effective electrical networks among the micron-sized Ag flakes, and the contact interface was improved by the Ag nanoparticles self-assembled on the sidewall of nanotubes. This strategy provided extraordinary high conductivities for epoxy-based pastes and stretchable conductive films. Secondly, the highly anisotropic thermal property of carbon nanotubes was utilized to control surfacial thermochemical reaction [4] and generate thermopower waves [5]. Finally, membrane filters based on vertically-aligned multi-walled carbon nanotubes with superhydrophobicity and superoleophilicity were investigated to separate oil, water and other molecules [6].

NanoDays - Help Needed!
by Jeff Goecker 13 Apr '12

13 Apr '12

NanoDays, our annual event for K-12 students, will be held on April 26-27, 2012 from 9 am - 3 pm. The event is part of a national initiative to teach key concepts of nanoscale science and engineering. Our third annual NanoDays will bring over 1700students to Discovery Park, more than 2x last year's total. However, we still need volunteers to help with activities and other duties! The bad news: As of today, we only have approximately 15% of Birck students registered to volunteer. The good news: There is still time to volunteer to help! Please register for as much time as you can commit by Tuesday, April 17, 2012 via the NanoDays website (link on on the left side). Here, you will also be able to find out more about the event. The best news: All volunteers will receive a free lunch and a t-shirt! If you are planning to help with the event, but have not registered yet, please do so by Tuesday so that we can provide you with a t-shirt for the event. What are you waiting for? Please sign up today. Tell your friends to join you! NanoDays is an experience you will be proud to be a part of, especially knowing that you might be impacting the next generation of nanoscientists and engineers!

Seminar Friday 4/13 BNC 2001 1PM Alexei Sokolov
by Black, Nancy Lee 10 Apr '12

10 Apr '12

You are invited to attend a seminar hosted by Vlad Shalaev at BNC this Friday April 13th at 1PM in the afternoon. Ultrafast Coherent Phenomena: Physics and Applications Alexei Sokolov, Professor of Physics and Astronomy, Texas A&M University The basic physics of interactions between matter and short light pulses is of fundamental interest. Such interactions generally result in coherence effects where all molecules of a sample "dance" in unison. As an example, we have used molecular coherence to efficiently generate short bursts of light that are automatically synchronized with respect to the molecular oscillations. Furthermore, our work has shown that an increased and cleverly manipulated molecular coherence enables improvements in optical detection and sensing applications. Short laser pulses provide a unique tool for probing the environment. In particular, femtosecond pulses, when powerful enough, will produce laser filaments that have found intriguing remote-sensing applications. Femtosecond laser filamentation starts when nonlinear self-focusing overcomes beam diffraction, and results in a tightly-confined propagation over distances orders of magnitude longer than the Rayleigh range corresponding to the filament's transverse dimensions. In a recent experiment we have used filaments for sub-diffraction-limited imaging of remote objects. Alexei Sokolov was born on April 14, 1971 in Odessa, Ukraine, to a family of engineers. He obtained his first degree in 1994 from the Moscow Institute of Physics and Technology. In his Diploma work, performed in the Laser Biophysics Laboratory at the General Physics Institute, Russian Academy of Sciences, Sokolov focused on the development of integrated optical sensors that use Langmuir-Blodgett films as sensing elements. In 2001 he received a Ph. D. in Physics from Stanford University, where he worked in the Edward L. Ginzton Laboratory under supervision of Steve Harris. While in the Harris group at Stanford, Sokolov investigated electromagnetically induced transparency (EIT) effects in molecular systems, which lead to collinear generation of a wide coherent Raman spectrum with a possibility of sub-femtosecond pulse compression. After completing his Ph. D. work, Sokolov moved to Texas A&M University, where he currently holds a Professor position in Physics and Astronomy and a Stephen E. Harris Professorship in Quantum Optics. His overall expertise is in the field of laser physics, nonlinear optics, ultrafast science, and spectroscopy. His research interests center around applications of molecular coherence to quantum optics, ultrafast laser science and technology, including generation of sub-cycle optical pulses with prescribed temporal shape, and studies of ultrafast atomic, molecular, and nuclear processes, as well as applications of quantum coherence in biological and defense-oriented areas. Sokolov maintains a well-funded group at Texas A&M; he has supervised a number of postdocs and graduate students who have won numerous student awards. Thanks you from, Vladimir M.

by Black, Nancy Lee 09 Apr '12

09 Apr '12

Dear Colleagues, I would like to draw your attention to upcoming XPS workshop "XPS data analysis using CasaXPS" on April 12-13. The flier is available at http://www.purdue.edu/discoverypark/nanotechnology/XPS/xpslite.php and the registration is at www.conf.purdue.edu/xps<http://www.conf.purdue.edu/xps>. The data analysis is equally important to the data collection and therefore every group planing to use XPS should have at least one dedicated person capable to do basic XPS analysis. This will allow me to help you faster and more efficiently. Thank you and hope to see you on April 12-13!
