FW: Super-Resolution Microscopy Workshop, Tuesday, February 7th, 2012
by Black, Nancy Lee 03 Nov '11

03 Nov '11

This message is being sent on behalf of Aaron Taylor, Director, Bioscience Imaging Facility Greetings, Super-resolution microscopy is a new class of optical imaging techniques that can achieve sub- 50 nanometer resolution images of fixed, fluorescently-labeled samples. The Bioscience Imaging Facility is hosting a super-resolution microscopy workshop on Tuesday, February 7th, 10am-5pm. This workshop will include lectures and demonstration focusing on PALM, STORM, and SIM. Please consult the attached flyer for more information. Both Zeiss and Nikon will install their super-resolution microscopy systems at the Biosicence Imaging Facility for this workshop. These platforms will continue to be available throughout the remainder of February. This installation offers a special opportunity for researchers to test their own samples at super resolution. Please take this opportunity to run test samples, while these microscopes are available. RSVP to Aaron Taylor (abtaylor(a)purdue.edu) no later than Decemeber 1st, 2011, if you would like to run a test sample. Special sample preparation and special dyes are required in some cases, so please plan ahead. Best regards, Aaron Director Bioscience Imaging Facility Hansen Building, Room B032 201 S. University Street Purdue University West Lafayette, IN 47907-2057 abtaylor(a)purdue.edu<mailto:abtaylor@purdue.edu> 765-496-3148 http://www.purdue.edu/discoverypark/bioscience/facilities/imaging/index.php

“ORAU – Value through Partnerships” - 11/16
by Jeff Goecker 31 Oct '11

31 Oct '11

The Office of the Vice President for Research hopes that you will be able to attend a presentation by Dr. Arlene Garrison, Vice President for University Partnerships, Oak Ridge Associated Universities on Wednesday, November 16th, from noon to 1:30 p.m. in the Burton D. Morgan Center for Entrepreneurship, 121. To ensure maximum participation, we are placing this presentation over lunch and encourage you to bring your lunch or buy lunch in the Venture Café. Dr. Garrison is interested in discussing the possibility for Purdue to be a University Partner with ORAU. Please feel free to distribute this information to your faculty and encourage participation. We would like to know if you will be able to attend. We would appreciate it, if you could take a moment and R.S.V.P. to Cindy Ream at: cream(a)purdue.edu

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. She received degrees from UM (B.S. Physics, 1988), Cornell (M.S. Applied Physics, 1992), and UC-San Diego (PhD Materials Science, 1995). Following her PhD, she was a postdoctoral fellow in Physics at Carnegie Mellon University. In 1997, she joined the UM faculty as the Dow Corning Assistant Professor.

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.
