Rachel Goldman Seminar - Today Oct. 27th at 3:00pm in MRGN 206
by Turner, Jaime J 27 Oct '11

27 Oct '11

REMINDER: Special Seminar - Oct. 27th at 3:00pm in MRGN 206 Rachel S. Goldman University of Michigan Title: Ion-Induced Nanostructure Formation on Compound Semiconductor Surfaces Abstract: Ion-irradiation of semiconductor surfaces has emerged as a promising approach to generate a variety of self-organized nanostructures, ranging from islands to ripples to nanorods. We have examined ion-induced transformations for a wide variety of focused-ion-beam (FIB) irradiated III-V compound semiconductor surfaces. On Ga-V and In-V surfaces, FIB-irradiation beyond a threshold ion dose leads to the formation of Ga-rich droplets [1] and In-rich islands, respectively. Interestingly, the threshold ion dose increases with increasing surface binding energy, suggesting a key role of sputtering on nanostructure formation. For low binding energy compounds, the surface morphology evolves from pits to ripples, followed by the nucleation of islands on the ripple crests, and the subsequent formation of nanorods. Together, these results suggest a nanostructure formation mechanism based upon ion-induced non-erosive surface response, followed by preferential Group V sputtering and island-induced self-shielding. In this talk, I will discuss our investigations of nanostructure array formation on a wide variety of III-V surfaces, with a focus on the formation mechanisms and electronic and optical properties of InSb nanorods and Ga nanodroplets. I will also discuss progress towards the design and fabrication of 3D Ga nanodroplet arrays. Brief Bio: Rachel S. Goldman is a professor of MSE, Physics, and EECS at UM.

Update to Harrison Street Construction Project
by Totten, Mary J 26 Oct '11

26 Oct '11

From: May, Rebecca L Sent: Tuesday, October 25, 2011 5:01 PM Subject: Update to Harrison Street Construction Project Communications Announcement Purdue University - Physical Facilities TO: Building Deputies (Please distribute) FR: Physical Facilities DA: Tuesday, October 25, 2011 RE: Update to Harrison Street Construction Project Drivers are asked to use caution around the Harrison St. construction project. Please be aware of the following changes: 1. All vehicles traveling north and south on Russell St. are expected to stop at the stop sign at the intersection of Harrison St. Construction traffic will be traveling east and west along Harrison St. Traffic signs are to be obeyed. 2. Harrison St. is now closed from the intersection of Martin Jischke Dr. and Nimitz Dr. to the west side of S. Russell St. and will remain closed through the duration of the Harrison St. construction project. 3. A temporary traffic diversion is being put in place to allow work to be done on the roundabout at the intersection of Harrison St., Martin Jischke Dr. and Nimitz Dr. The diversion will direct drivers from the south side of the police station west through the parking lot to Gates St. This pattern will be in place by the evening of Saturday, October 29 and will remain in place until the completion of the roundabout. 4. On November 3 and 4, contractors will be working on soil stabilization on Harrison St. between Gates St. and South University Dr. Please beware of dusty driving conditions. A map of the area is available here: http://www.purdue.edu/physicalfacilities/travel/pdf/2011_Harrison_Closures_… For questions or concerns, please contact Dan Pusey at 714-1593.

Reminder [Me-faculty] ME Graduate Seminar-today

MECHANICAL ENGINEERING GRADUATE SEMINAR OCTOBER 20, 2011 4:30 P.M. ROOM ME 1061 Dr. H. Tom Soh Ruth Garland Professor of Materials & Mechanical Engineering UC - Santa Barbara (UCSB) "Sorting Cells and Evolving Molecules in Microfluidic Systems" Abstract: Current techniques in high performance molecular and cellular separations are limited by the inherent coupling among three competing parameters: throughput, purity, and recovery of rare species. Our group utilizes unique advantages of microfluidics technology to decouple these competing parameters by precise and reproducible generation of separation forces that are not accessible in conventional, macroscopic systems. In this seminar, we will first discuss novel high performance electrokinetic, magnetophoretic and acoustophoretic separation systems to purify rare target cells from complex mixtures. Next, we will present our recent work in applying the microfluidic separation systems for Rapid Directed Evolution of molecules (RDE). We will provide theoretical and experimental evidence for extremely fast generation of affinity reagents -molecular recognition elements that bind to target molecules with high affinity and specificity. Finally, we will present innovative methods of evolving molecular machines that are capable of performing complex functions, including binding induced switching and conformation change. Brief Bio: Dr. Soh received his B.S. with a double major in Mechanical Engineering and Materials Science with Distinction from Cornell University, and Ph.D. in Electrical Engineering from Stanford University. Prior to joining UCSB in 2003, Dr. Soh served as the technical manager of MEMS Device Research Group at Bell Laboratories and MEMS R&D group at Agere Systems. His current research interests are in analytical biotechnology, especially in high throughput screening, directed evolution and integrated biosensors. He is Co-Director at the Center for Stem Cell Biology & Engineering and affiliated with the Institute for Collaborative Biotechnologies and the California Nanosystems Institute. He is the recipient of the MIT Technology Review's "TR 100" Award (2002), ONR Young Investigator Award (2004), Beckman Young Investigator Award (2005), the ALA Innovator Award (2009), a NIH Director's TR01 Award (2009), Johh Simon Guggenheim Fellowship (2010), Edward C. Nagy Lectureship, NIH (2011), and the Garland Endowed Chairship at UCSB (2011). Reception 4:00 p.m. in common area outside ME 2137 - Gatewood Wing Diana K.
