Atrium Display Pumpkin Carving Party Seminar Sunrise Award Atrium Display New: Down Equipment Summary on the Upper Atrium Display In an effort to communicate better with the user community on the status of down equipment, we're starting an activity that will put more information on the upper atrium big-screen display. We will put the down equipment name, why it is down, the estimated time for repair, and the responsible staff engineer. We believe this will provide users with valuable information regarding the off-line equipment and a way to better plan around the time it is anticipated to be returned to service. After we begin this communication next week we would certainly welcome feedback on the usefulness of this approach, and we would like to hear any suggestions on how to improve the information. Ron Pumpkin Carving Party Please join us for a pumpkin carving party in the atrium at 3:30 pm on Friday, October 24th. A limited number of pumpkins will be purchased and distributed on a first come first serve basis. We have some decorating supplies but please feel free to bring your own. The pumpkins will be on displayed for 1 week. Please stop by the display and vote monetarily for your favorite. The money will be used for fun activities held in Birck.

Prof. Miko Cakmak Seminar TODAY at 4:00 pm

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.
