Prof. Miko Cakmak Department of Polymer Engineering, University of Akron Thursday, October 16th at 4:00 pm MRGN 121 BNC Distinguished Seminar Series Field Assisted "Z" orientation of Nanophases to Produce Functional films using a Novel Roll to roll manufacturing platform Electric1,2, Magnetic3, and Thermal gradient5,6 fields are three important methods used in Field Assisted Self Assembly (FASA) of polymer blends, block copolymers, liquid crystals and polymer nanocomposites. These assisted assembly techniques have been used in laboratory scale, but for potential applications such as flexible electronics7, membranes8, supercapacitors9, fuel cells10, photovoltaic's etc. a large scale manufacturing platform is needed. We introduce a novel roll to roll process developed in our laboratories to achieve "Z-direction" alignment of nanostructural units. A 70 ft. line was designed which uses a casting system to deposit desired thickness of liquid such as a monomer and/or polymer solution up to 6" wide on a flexible substrate using a doctor blade system and flow coating system to deposit thin films. The substrate is then carried by pretensioned steel belt through an electric field application zone which consists of a parallel electrode sitting on top of the steel belt with the solution cast film passing below it. The electric field applied can be a DC, AC or a biased AC, hence using the various fields we can maximize the orientation by increasing the dielectric contrast between the particles and the matrix. If orientation and self-assembly through magnetic field is desired, the second tool located downstream is activated. This electromagnet is capable of applying magnetic fields up to 2. 2 T to the material supported by a flexible substrate through the opposing poles. This line also contains a movable UV lamp which can be used to freeze the structure of required morphology using photocurable resin and could also be used to etch one phase of a polymer blend or block copolymer after electric field or magnetic field application zones. The final tool that is built on this machine is the Thermal Alignment zone. It is designed to apply a "line of heat" oriented transverse to the line direction at 9 different zones. In each zone the material may be subjected to a temperature gradient in the machine direction through a successive heating and cooling units. The temperature gradients can be created using conduction or radiation. Electric and magnetic field alignment of particles and polymer chains is studied through real time birefringence measurement, to determine various parameters effecting the orientation of particles/phases inside a polymeric film under the magnetic or electric field. The birefringence system is based on the solution drying process developed in our lab11. References: (1) Park, C.; Robertson, R. E. Materials Science and Engineering: A 1998, 257, 295-311.

Cleanroom Flu Shot Parking Preventative Maintenance Pumpkin Carving Party Sunrise Award Cleanroom Buddy Policy Some suggestions have been made to re-evaluate our acid hood buddy policy due to problems scheduling a buddy during afterhours. Unfortunately this is a Purdue-wide policy put in place for safety, namely that any acid work done in a hood needs to have a second person somewhere in the vicinity due to the dangerous nature of the work. We understand the scheduling challenges but this policy needs to continue to be enforced not only because it is a Purdue requirement, but also because it is the right & safe thing to do. Thanks for your understanding. Sample Prep Storage It was suggested that some small number of laboratory drawers be provided for sample prep storage, especially for students who come and go from Birck frequently. The analogy is the way we use student lockers to store personal belongings while visiting and working at Birck. Steve will investigate the possibility of finding a small area that is safe and accessible for this, but it becomes complicated because of swipe-in access to labs and a very limited number of unused drawers. Steve will see if this is feasible. Bio-Cleanroom Waste Disposal A very good suggestion was made this week to better categorize the different waste products from the Bio-cleanroom, and then use the proper disposal procedures for a given material. Steve will develop a list, which can be expanded over time, to describe the proper waste disposal for a variety of bio-cleanroom materials. This may be put on the website or locally in the bio-cleanroom. Personal Electronics Use in the Cleanroom and Labs A staff member observed a user in the cleanroom playing video games on a tablet device while simultaneously doing research-related work. Please note that this can potentially be a dangerous situation if chemicals and/or processes are trying to be managed while distracted by personal electronic devices. Please use common sense when interfacing with your personal electronics, doing so only when it is safe and when you don't have research activities underway. In addition, please remember to wipe down all devices and/or materials in the gowning room prior to bringing them into the cleanroom. Thanks, and keep your good suggestions coming.

[cid:image003.jpg@01CFD8AC.2F191060] Dr. Dana Weinstein Massachusetts Institute of Technology RF Solid-State MEMS Resonators Monday, October 6, 2014 10:00 a.m. Birck Nanotechnology Center Room 1001 Abstract Semiconductor micro-electromechanical (MEM) resonators, with quality factors (Q) often exceeding 104 can provide a high performance, low-power, compact alternative to electrical components in wireless communication and signal processing. The seamless integration of these MEM devices in standard IC technology is particularly attractive due to reduced size, weight, and power, reduced parasitics leading to higher operational frequencies, and relaxed constraints on impedance matching networks. In this talk, I will discuss the design innovations in transduction and acoustic confinement that enabled the demonstration of solid-state MEMS resonators in standard Si CMOS and GaN MMIC technologies. This work has led to the highest f.Q products in both Si and GaN reported to date, to record-breaking resonance frequencies in Si, and to the first monolithic MEMS oscillators in GaN. I will discuss the methods used to achieve this performance, including active electromechanical transduction, 2D and 3D phononic crystal design, and modeling used to optimize these unique structures. Bio Dana Weinstein is an Associate Professor in the Department of Electrical Engineering and Computer Science at MIT, and a member of the Microsystems Technology Laboratories. Dana received her B.A. in Physics and Astrophysics from UC Berkeley in 2004, then moved to Cornell University where she completed her Ph.D. in Applied Physics in 2009, working on multi-GHz Micro Electro-Mechanical Systems (MEMS). Her research group at MIT, the HybridMEMS Lab, focuses on the development of novel MEMS-enhanced electron devices and systems for high performance, low power consumption, programmable electromechanical signal processors operating in real time at carrier frequencies. Dana is the recipient of the NSF CAREER Award, the DARPA Young Faculty Award, the Intel Early Career Award, and the IEEE IEDM Roger A. Haken Best Paper Award.
