We've added new computers running Linux to the cleanroom. These computers have internet access and are for the convenience of our facility users. If you haven't used Linux before it shouldn't be a problem because these systems have a user interface very similar to Windows and Macintosh. You do not need to log in, they all use a single shared user account and come pre-loaded with a variety of useful software. We're using Ubuntu Linux 12.04LTS.
Our Leitz Microscope has a new 10 mega pixel camera and updated software. A new SOP has been added to our website http://nanofab.uh.edu/equipment/analysis/optical-microscopes (you have to be logged in to access it.)
The new JEOL JBX-5500 e-beam lithography system will be available for all UH Nanofab users starting November 1st 2012. Please contact Nanofab staff to arrange training.
The JBX-5500FS electron beam lithography system is designed for writing patterns with nanometer precision. The system produces a 50 kV electron beam from a ZrO/W emitter and a four-stage electron beam focusing lens system. A 4 nm wide gaussian beam is vector scanned at a rate of 12 MHz with scan increments of 0.5 nm to produce high fidelity patterns from a CAD layout. A high-speed stage equipped with a laser position system enables patterns to be written across an entire 100 mm wafer. The intuitive interface provide ease of use enabling a new user to produce sub 50 nm patterns independently in as little as 4 hours of training.
The sample exchange rod for the UHV Sputtering System has a small machined part with three 'fingers' mounted on the end; an accidental drop caused one of these fingers to break off. Because of the three-dimensional nature of the part it would be an involved process to make in the machine shop, instead a relatively simple 3D model was created using Alibre (www.alibre.com) and the part was ordered from Shapeways (www.shapeways.com) where it was made using a 3D printing process. The part is made from bronze-infused stainless steel powder; it has slightly different dimensions form the original due to limitations on the printing process but it is a completely functional replacement that required very little design time and minimal cost.
Join us Friday Oct 12, 2012 from noon to 1:30pm on the UH campus at Engineering Building 2 (Building D3) Room W122 for free pizza and learn what you can do at the UH Nanofabrication Facility.
FEI and National Geographic are sponsoring an image contest for users of FEI's electron microscopes. If you have an image that you've taken from either our SEM or Dual Beam FIB you can enter it in the contest. You will need to set up an account on FEI.com, contact the UH Nanofabrication Facility Manager for information you will need to set up the account.
Prof. Vekilov's pioneering work on protein nucleation has been featured in the University of Houston Cullen College of Engineering Paramaters magazine.
Dr. Shiva Bhaskaran will be leaving the UH Nanofab Facility to join the MRL at the University of Illinois at Urbana-Champaign. Shiva has been a valuable member of the UH Nanofab team and his steadfast support, patience and expert knowledge will be missed by all. From the Facility Director and the Facility Manager we wish you best of luck in all your future endeavors Dr. Bhaskaran.
