Director Announcement Glassware Storage Refrigerated Orders Seminar Special Notes (Extended Holiday Shutdown) University Winter Recess UPS SHUT DOWN (Uninterruptable Power Supply) Director Announcement Dear Birck Users and Research Community, With the extended break this year between the Christmas and New Year's holidays the university will be closed for 11 days in a row, beginning Thursday, December 24th and concluding Monday morning, January 4th. This represents a new challenge for us to maintain some limited research capability while the university is officially closed with no staff members present. Therefore the Birck Nanotechnology Center will implement the following policy for the duration of this period: 1. No toxic, flammable, or hazardous gases will be available. This includes hydrogen, methane, silane, dichlorosilane, ammonia, nitric oxide, chlorine, KrF. These gases will be shut off at the source and no processes using these gases will be allowed. 2. Cleanroom and laboratory operations will still be available as long as they don't use any hazardous gases. 3. Fume hoods will be open for use but please make sure someone else is nearby if you're going to work alone in the hood. 4. Stocked materials should be especially conserved by all users as no deliveries to the university will occur during this period. 5. Cleanroom users should continue to re-use their cleanroom gowns and other garments as much as possible since the shipping of used garments to our laundering supplier will be unavailable during this time. 6. No staff will be working normal hours but some may intermittently stop in for brief walk-throughs and checks. Please also note that custodial services will be suspended during this time period as well. Thank you for your support of this extended period of time for staff, faculty, and students to enjoy time off with family and to refresh. Also, thank you in advance for your professionalism in maintaining our great facility through the duration of this holiday and university recess period. Ali Shakouri Dimitri Peroulis Glassware Storage IN this week's survey a user asked if we could provide a storage location for glassware different from the totes in the cleanroom. We have such an arrangement now, if you're interested in using this option please see Dan Hosler for more information. Refrigerated Orders Refrigerated or frozen shipments - If you are expecting any temperature sensitive shipments during the holidays, we cannot guarantee that they will be stored correctly until we get back from Christmas Holiday. Fed-Ex and UPS does not have enough freezer and refrigerator space for holding all shipments. If you have any questions, please let us know. Mary Jo and Kyle Seminar Amar S. Basu Wayne State University High Throughput Screening in Droplet Microreactors Tuesday, December 15th at 3:00 pm in Birck 2001 For more information please visit: https://nanohub.org/groups/bnc/calendar/details/1407 Special Notes (Extended Holiday Shutdown) UltraPure Water System Maintenance The UPW system is scheduled for ion-exchange resin replacement during the extended holiday shutdown period. This means that UltraPure water will not be within specification from Monday, December 28th at 8:00 am until Monday, January 4th at 8:00 am. The replacement of the resin occurs in phases and during each phase of new resin installation a flush and purification process will be run. So during this entire week the water will have elevated organics, especially amines. This resin replacement procedure will require a number of days to finish, and then flushing and purification to achieve UPW specifications. Water will still be available during this period but please note it will be out of specification and therefore use UPW at your own risk. The process should be complete and meet UPW specifications by Monday, January 4th. Please Reuse the Blue Shoe Covers During the extended holiday shutdown period we will not be able to restock the blue shoe covers at the entrances to the pre-gowning area. Therefore, please reuse your shoe covers several times, storing them in your assigned cubby after each use. Please only replace them with new ones when they're obviously worn. University Winter Recess Purdue University will be CLOSED December 24th through January 3rd, please plan accordingly. UPS SHUT DOWN (Uninterruptable Power Supply) On 7 January 2016 Purdue Physical Facilities will be shutting down the center's Uninterruptable Power Supply (UPS) power to the front half of the building. The outage is needed to add electrical capacity to the UPS distribution system. As result of this UPS interruption there is a direct impact on the building control systems resulting in shutting down HVAC and chemical exhaust systems for both east and west laboratory wings. This requires us to shut down laboratory activities that involve exhausted hoods, vacuum systems, and/or toxic gases - no chemical work will be allowed during this period. However, work that involves taking standard electrical measurements may be carried out in the LABS provided that fluctuating air temperature and humidity do not affect the readings. The UPS interruption should take from 4 to 8 hours to complete - barring any unforeseen issues. Normal power in all the laboratories will not be affected and will available during the time the UPS power is shutdown. The cleanroom UPS power will not be affected as well. Thank you for your cooperation and understanding during these important upgrade. BNC Management

Seminar featuring Amar S. Basu - High Throughput Screening in Droplet Microreactors
by Anthrop, Heather L 09 Dec '15

09 Dec '15

Amar S. Basu Associate Professor, Electrical and Biomedical Engineering Wayne State University Tuesday, December 15th at 3:00 pm Brick 2001 High Throughput Screening in Droplet Microreactors Multiphase microfluidics utilizes water-in-oil droplets as vessels for chemical reactions. With volumes of nL-pL, they can provide reaction volumes one million-fold smaller than conventional microplates, enabling new experimental approaches for high-throughput chemistry and biology. In order to leverage these benefits, one must be able to perform conventional fluid handling operations in the droplet format. Multiphase microfluidics is considerably more complex than single phase flow, as it involves multiphase flow interactions, interfacial tension, Laplace pressures, interfacial adsorption, and other phenomena acting in cohort with laminar flow. Rather than work against these phenomena, we exploit them in novel ways in order to perform key fluid handling and sensing operations. This talk will discuss several such technologies being explored in our group: 1) the formation of heterogeneous droplet screening libraries using microfractionation-in-droplets (µFD); 2) Concentrating particles in plugs, exploiting hydrodynamic microvortices and sedimentation inherent to plug flow; 3) Light-based manipulation of droplets using optofluidic tweezers (OFT), a novel technique which uses laser-induced thermocapillary microvortices to trap droplets with µN forces (100,000X larger than traditional optical tweezers); 4) Sorting droplets by size using tensiophoresis, the cross-stream migration of droplets in an interfacial tension (IFT) gradient; and 5) Detecting femtomoles of proteins in droplets using interfacial adsorption phenomena. Experimental and computational methods will be discussed. Bio: Amar Basu received a BSE and MSE in electrical engineering in 2001 and 2003, an MS in biomedical engineering in 2005, and a Ph.D. in electrical engineering in 2008, all with honors from the University of Michigan Ann Arbor. His dissertation work, under Prof. Yogesh Gianchandani at the NSF Center for Wireless Integrated Microsystems, investigated interfacial-tension based fluid actuators. Amar worked with Intel's Advanced Technology group, General Motors, Silicon Graphics, and served as an adjunct faculty at the University of Michigan. He is currently associate professor of electrical engineering and biomedical engineering at Wayne State University. His research, supported primarily by the NSF, focuses on microfluidic and microelectronics for high throughput screening and point of care monitoring.

Steam Update
by Kuhn, Jeffrey G 08 Dec '15

08 Dec '15

All, Unfortunately, the steam supply issue from Wade power plant persists as of this writing. Therefore, toxic gases remain off and the cleanroom, biocleanroom, and J Bay labs remain closed. At this time, the non-cleanroom laboratories are open and research may proceed. However, we cannot guarantee temperature or humidity stability in the labs and it is possible that we may have to close those labs as well if the steam situation worsens. We don't have a timeline from Wade as to when the steam pressure will return to normal. Rest assured that we will reopen the cleanroom areas as soon as it is safe to do so.

Update
by Kuhn, Jeffrey G 07 Dec '15

07 Dec '15

All, Unfortunately, it will be several hours before steam comes back online. We are nearly to the point that the air handlers for the labs and cleanroom could shut down automatically, therefore we must shut down all of our toxic gases and suspend all operations until further notice in order to keep people safe. Sorry for the short notice, but this latest situation developed very quickly. Jeff Kuhn Facility Engineer Birck Nanotechnology Center Purdue University 1205 W.

Coral Access
by Shepard, Jeremiah J 07 Dec '15

07 Dec '15

All, We have been experiencing problems with the coral interlock server in the past week, and we continue to experience problems. We are working hard on solving the problem and apologize for any inconvenience this has caused. We have made some adjustments which allow the system to auto-recover from these problems while we work on a permanent solution. In the interim, please continue to use the coral system as you always have. However, if you experience problems with enabling or disabling tools, the system may be executing auto-recovery, please wait 5-10 minutes and try your action again. If you continue to experience problems after 5-10 minutes please notify the engineering staff. Thank you, Jerry Shepard Birck Nanotechnology Center West Lafayette, IN 47909-2057 Phone: 765-494-3480
