2019 – 2020 Holiday Shutdown Notice

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 12 days in a row, beginning Friday, at 3:30PM December 20^th and concluding Thursday morning, January 2^nd.  Please note the time and complete any processes requiring hazardous gases before 3:30 pm Friday. This represents a 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 time period:

1. No toxic, flammable, or hazardous gases will be available.  This includes hydrogen, methane, silane, dichlorosilane, ammonia, H2S, ALD sources, BCl3, nitric oxide, chlorine, & KrF.  These gases will be shut off at the source and no processes using these gases will be allowed. 
2. Nitrogen, argon, helium, forming gas, SF6, CF4, C4F8, and oxygen will continue to be available.
3. Cleanroom and laboratory operations will still be available as long as they don’t use any hazardous gases. 
4. Fume hoods will be open for use but please make sure someone else is in the same lab area or cleanroom bay if you’re going to work alone in the hood.  No HF, BOE, or TMAH work is to be performed during this time.  The RCA Hood will be unavailable for use.
5. Loading dock will be closed with no shipping and receiving coverage and no deliveries accepted.
6. There will be no custodial service during holiday time so trash and bathroom conditions will not be maintained.
7. Stocked materials should be especially conserved by all users as no deliveries to the university will occur during this period, and stocking of on-hand materials may occur on a very limited basis. 
8. 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.
9. Staff will not be working normal hours but some may intermittently stop in for brief walk-throughs and checks.

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.

RA Position

The Spintronics Lab (BRK 1157) needs a 1/4 - time RA (10 hrs/wk) to help Neil Dilley, the research scientist in charge of the lab. The position offers the student thorough training on two widely-used cryogenic measurement systems, the Quantum Design MPMS-3 SQUID and PPMS DynaCool :

• Measurement capabilities: DC and AC magnetic properties, magneto-transport, thermal transport and magnetic dynamics over a wide range of temperatures and applied magnetic fields
• Samples investigated: bulk materials, thin films, or devices

After becoming familiar with the instruments, the student will assist with various research activities, including:

· Training new users; helping them with initial measurements; troubleshooting measurement artifacts

· Helping Neil keep the instruments and lab tools organized and working smoothly

· Testing new capabilities of systems and contributing to technical notes about the results. Example: characterize signal/noise (vs. frequency, angle, and temperature) for new rotatable sample holder for ferromagnetic resonance (FMR) probe in DynaCool

· Measuring research samples from external users; analyze data and present brief reports on the results

· Working with vendors to resolve technical issues on the instruments

Microfluidics course announcement – Spring 2020 (see attached announcement for more details)

Microscopic flows are everywhere these days. In fact they’ve always been all around us but we haven’t noticed. Despite their prevalence in science and engineering fields, they are not well understood—in large part because the fluid mechanics intuition developed in the study of macroscale flows frequently does not apply to microscopic flows. This class will prepare engineers and scientists to address problems they will encounter when studying the behavior of fluid flows in microscopic domains. The course will concentrate on behaviors not typically important at large length scales that become very important at small length scales, such as Van der Waals forces, surface tension, and electrostatic forces. The course will take a largely analytical approach to studying these flow phenomena although some computational modeling will also performed and several lab demos and visits are planned. Previous experience with graduate level fluid mechanics (i.e. Navier-Stokes solutions) or continuum mechanics will be helpful. Some computational analysis of model problems may be performed using commercial software (ANSYS/Fluent/COMSOL or related).

Instructor: Steve Wereley, Mechanical Engineering (wereley@purdue.edu)

Course Objectives:

1. To learn how fluids behave in microscopic domains that are still large enough for continuum flow approximations to hold.

2. To learn where the continuum assumptions are no longer valid.

3. To learn how to treat sub-continuum fluid flows.

Prerequisites by Topic: The student should be of graduate standing. The student should have had some previous experience with graduate level fluid mechanics, in particular solving the Navier-Stokes equations.

Computer Usage: The students may need to use ANSYS, Matlab, Fluent, COMSOL or a comparable package, to perform some of the computations necessary for the course.

Assessment Methods: Grades will be based on homework assignments, two projects, and a final exam. The relative weight of these components is 25%, 50%, and 25%, respectively.

Jischke Drive Repairs – April – August, 2020

Project Overview

South Martin Jischke Drive from State Street to Harrison Street will be repaired next year, and utility work in the area will also occur. This section of South Martin Jischke Drive will be closed in phases while work is ongoing, and some adjacent sidewalk and ramps will be unavailable. We will be constructing a pedestrian “bump out” on the east and west side where the cross walks are located.  The bump out will improve pedestrian safety.  We will also be adding a short section of bike lane that will connect the existing bike lane that dead ends at the south end of Burton Morgan Dr. with bike lane at the corner of State and Jischke. 

Project Schedule

While we are still in the design phase and the schedule is not yet final, we anticipate sidewalk repairs and utility work will begin in April 2020 with road closures beginning in May. Road work will be completed in two phases after spring commencement and before Boiler Gold Rush in August. The first phase will close northern half of the road from State Street to just south of the TERY parking lot entrance. This section will be reopened after repairs are complete, and then the remaining portion of South Jischke Drive from south of the TERY parking lot to Harrison Street will close for repairs. Access to TERY will be maintained throughout the project. Parking along Jischke will not be available during construction. 

Our Request for Your Participation

To streamline feedback, occupants should communicate needs and concerns for April-August 2020 with their assigned building deputy. Topics may include, but are not limited to the following:

• Vehicular / pedestrian access from South Jischke Drive
• Parking – temporary accommodations during construction
• Operational needs such as deliveries (provide truck size and frequency)
• Visitors or summer conferences – access and communications that are needed for visitors
• Trash / recycle pick up, including current locations and potential summer options

Please communicate any needs and concerns with the appropriate assigned building deputy, see below.

• Steve Rudolph – MRGN, MANN sgrudolph@purdue.edu
• Phil Austin – BIND pjaustin@purdue.edu
• Mary Jo Totten - BRK tottenm@purdue.edu
• Eric Ridgley – DLR ewridgley@purdue.edu
