Dear Birck Faculty and Staff, Please read Suresh's email below. Donna Brown Business Manager Birck Nanotechnology Center (765)494-1619 From: Tanner, Catherine A On Behalf Of Garimella, Suresh V Sent: Monday, July 27, 2015 12:59 PM Cc: Bolin, Jeffrey T; Garimella, Suresh V; Brown, Stacy L. (Discovery Park); Brown, Donna J Subject: DP Chief Scientist and Executive Director This email is being sent to DP Directors, Managing Directors, and Administrative Assistants. Please forward this message within your centers. Dear Discovery Park family, As you may have heard, we are very pleased that Tomás Díaz de la Rubia will be joining us as Chief Scientist and Executive Director of Discovery Park. He will start in mid-August; a press release will be issued within a few days. The search process has engaged the president, trustees, provost, deans, and others across campus who are clearly energized about the possibilities, and have expressed great hopes for significant growth in the recognition and profile of DP. You will all be critical to achieving what we all believe to be the true potential of DP. Until Tomás arrives, please consider me to be serving in an acting role in this position. A DP Directors meeting will be scheduled for after Tomás arrives in August. Dave Kotterman is serving as an interim in Candiss' place for some of the more operational details, and he will be working closely with Candiss. Jeff Bolin is in charge of DP space-related issues. Our DFA Stacy Brown, as you know, has deep knowledge of DP, and we are also hopeful of announcing the ADFA for DP in the very near future. So, we will be well-staffed, and remain responsive to your needs. If you have any questions or suggestions, please don't hesitate to reach out. Thank you, Suresh

Spintronic Research Scientist Candidate Seminar - July 22nd
by Turner, Jaime J 21 Jul '15

Dr. Noel D'Souza Spintronics Research Scientist Candidate July 22, 2015 @ 1:30pm in BRK 1001 Applications of 4-State Nanomagnetic Logic using Multiferroic Nanomagnets and Experiments on 2-State Multiferroic Nanomagnetic Logic Abstract Nanomagnetic logic, incorporating logic bits in the magnetization orientations of single-domain nanomagnets, has garnered attention as an alternative to transistor-based logic due to its non-volatility and unprecedented energy-efficiency. The energy efficiency of this scheme is determined by the method used to flip the magnetization orientations of the nanomagnets in response to one or more inputs and produce the desired output. Unfortunately, the large dissipative losses that occur when nanomagnets are switched with a magnetic field or spin-transfer-torque inhibit the promised energy-efficiency. Another technique offering superior energy efficiency, "straintronics", involves the application of a voltage to a piezoelectric layer to generate a strain which is transferred to an elastically coupled magnetrostrictive layer, causing magnetization rotation. The functionality of this scheme can be enhanced further by introducing magnetocrystalline anisotropy in the magnetostrictive layer, thereby generating four stable magnetization states (instead of the two stable directions produced by shape anisotropy in ellipsoidal nanomagnets). Numerical simulations were performed to implement a low-power universal logic gate (NOR) using such 4-state magnetostrictive/piezoelectric nanomagnets (Ni/PZT) by clocking the piezoelectric layer with a small electrostatic potential (~0.2 V) to switch the magnetization of the magnetic layer. Unidirectional and reliable logic propagation in this system was also demonstrated theoretically. Besides doubling the logic density (4-state versus 2-state) for logic applications, these four-state nanomagnets can be exploited for higher order applications such as image reconstruction and recognition in the presence of noise, associative memory and neuromorphic computing. Experimental work in strain-based switching has been limited to magnets that are multi-domain or magnets where strain moves domain walls. In this work, we also demonstrate strain-based switching in 2-state single-domain ellipsoidal magnetostrictive nanomagnets of lateral dimensions ~200 nm fabricated on a piezoelectric substrate (PMN-PT) and studied using Magnetic Force Microscopy (MFM). A nanomagnetic Boolean NOT gate and unidirectional bit information propagation through a finite chain of dipole-coupled nanomagnets are also shown through strain-based "clocking". This is the first experimental demonstration of strain-based switching in nanomagnets and clocking of nanomagnetic logic (Boolean NOT gate), as well as logic propagation in an array of nanomagnets.

New Mailroom Employee Please stop by and introduce yourself to our new receiving clerk Kyle Corwin. Kyle just started with us and his hours in BRK 1220 will be 9AM to 1PM Monday - Friday. With Kyle, we will be able to keep the mailroom open over the lunch hour. Outbound Mail & Package Time Change MMDC has changed their mail route again, so you have until 10:00AM before the mail goes out. This means that any packages and mail received by 10:00AM will still go out that day! VB6 The VB6 remains down. Raith/Vistec service has been here this week working on the problem, and additional parts have been ordered from the factory. The service engineer is staying through the weekend and until the issue is resolved. Thanks for your patience.

Ariba Training Citizenship Lab 2031 Chemical Clean-Out OSHA/Fire Safety Inspection VB6 Ariba Requester Training Open for Enrollment P2P 200—Creating Requisitions in Ariba is scheduled for Tuesday, July 21, 2015. The session will meet from 8:30 a.m. to 11:00 a.m., in FREH 248, the training room located on the second floor of Freehafer Hall. This hands on class will meet in a computer lab. Participants will use a training environment to Create Catalog and Non-Catalog Requisitions, Monitor Requisition Status and learn how to Withdraw or Edit a Requisition. Staff can ensure a space in the class by following these enrollment steps: 1. Click P2P 200 – Creating Requisitions in Ariba<https://www.eventreg.purdue.edu/training/CourseListing.asp?master_id=4026&m…> to open the training registration site. 2. Click Add to Cart. 3. Click Checkout. 4. Sign in with Purdue career account and password. 5. Verify that the registration information that displays is correct and click Submit. Citizenship In this week’s survey it was noted that we still occasionally have citizenship challenges, such as users leaving hoods and equipment in disarray. The writer was frustrated that some users don’t clean up after their processes are complete or they disregard the work of others nearby. Please be aware of others’ research around the facility . . . we have over 400 users at Birck and we serve all science and engineering departments at Purdue. We also have outside users coming to use our facilities, so please let’s be proud of our world-class capabilities and keep them in top-notch condition for all users. Lab 2031 Chemical Clean-Out Beginning the week of July 20th we will be cleaning out old chemicals from Lab 2031. Any chemical over 5 years old will be put aside for 2 weeks, after which they will be disposed of. If you need any of these chemicals retained please see Ira. OSHA/Fire Safety Inspection We will have an OSHA/ fire safety inspection starting Monday (July 13th), please watch and correct the following: -Removal of any unlabeled chemicals in labs -Removal of any extension cords that do not have an integrated 15A breaker -Removal of any boxes/ paper or other materials that could present a fire hazard -Remove any equipment, chairs or other items that block exits from the lab -Remove any tripping hazards that extend across isle ways Your assistance is appreciated in this matter, Stephen Stephen E. Jurss CIH, CSP Safety Officer Birck Nanotechnology Center 1205 W. State Street West Lafayette, IN 47907 Tx: 765-496-8337 E-mail: sejurss(a)purdue.edu<mailto:sejurss@purdue.edu> VB6 The VB6 has experienced a communication problem between the internal robot and the stage mechanism. We’ve exhausted all phone support for the issue, and Raith/Vistec has agreed to send service personnel to Birck to resolve the problem. Bill Rowe is working with the company to schedule the visit, and we anticipate it will occur the week of July 13th.
