Nanostructured materials have become critically important in many areas of technology ranging from renewable energy, electronics, and photonics, to biology and medicine, because of their unusual physical/chemical properties due to confined dimensions of such materials. This talk will present a new class of polymeric materials we developed recently: nanostructured conducting...

BSAC Seminar: Exosome Cancer Research Powered by Microfluidics

February 21, 2017
Prof. Mei He Department of Biological and Agricultural Engineering, Kansas State University Nanotechnology Innovation Center Berkeley Postdoc 2011, Amy Herr Group February 21, 2017 | 12:00 to 01:00 | 490 Cory Hall Host: Liwei Lin

Most eukaryotic cells release exosomes that are membrane vesicles derived from the endolysosomal pathway with a size range of ~30-150 nm. Exosomes play important biological roles via transferring selectively enriched proteins, RNAs, and mitochondrial DNA, which presents distinctive opportunities for liquid biopsy analysis of cancers....

BSAC Seminar: A Novel Approach for High Efficient Electrostatic Micro/Nano Transducers

February 7, 2017
Dr. Harald Schenk Director, Fraunhofer Institute for Photonic Microsystems Professor of Micro- and Nanosystems, Brandenburg University of Technology February 7, 2017 | 12:00 to 01:00 | 490 Cory Hall Host: Michael Cable

Electrostatic forces provide excellent scaling behavior that makes them first choice for micro and nano actuation. However, large stroke is at cost of large electrode gaps preventing to make use of this advantage. As a consequence, other driving mechanisms like piezoelectricity or electromagnetism are applied - although...

BSAC Seminar: Dynamic Characterization of MEMS Using Laser Doppler Vibrometry

April 11, 2017
Eric Lawrence MEMS Business Development Manager, Polytec Inc. April 11, 2017 | 12:00 to 01:00 | 540 Cory Hall Host: Michael Cable

Laser Doppler Vibrometry (LDV) is a technology widely used by research institutions for dynamic characterization of MEMS. This technique features microscope-based velocity measurements using the Doppler effect and has unique features in comparison to other available techniques. LDV offers high resolution down to the picometer level, bandwidth to 1.2 GHz, high accuracy, and wide dynamic range. Extension of this technique to...

BSAC Seminar: III-V Quantum Structures for Infrared Detection

September 5, 2017
Dr. Sarath Gunapala Jet Propulsion Laboratory, Infrared Photonics Group September 5, 2017 | 12:00 to 01:00 | 531 Cory Hall Host: Ming Wu

There are many applications that require long wavelength, large, uniform, reproducible, low cost, stable, and radiation-hard infrared (IR) focal plane arrays (FPAs). For example, the absorption lines of many gas molecules, such as ozone, water, carbon monoxide, carbon dioxide, and nitrous oxide occur in the wavelength region from 3 to 15 microns. Thus, IR imaging systems that operate in the long...

BSAC Seminar: Order and Chaos*: Collective Behavior of Crowded Drops in Microfluidic Systems

May 9, 2017
Prof. Sindy KY Tang Stanford University, Department of Mechanical Engineering May 9, 2017 | 12:00 to 01:00 | Wozniak Lounge, Soda Hall Host: Liwei Lin

Droplet microfluidics, in which micro-droplets serve as individual reactors, has enabled a range of high-throughput biochemical processes. The talk will start with our recent application on using droplets to identify microbes, specifically methane-metabolizing bacteria, for the more efficient generation of bioplastics. Unlike solid wells typically used in current biochemical assays, droplets are subject to instability...

BSAC Seminar: Transfer Printing for LEGO-Like Microassembly and Nanomaterial Integration
