Carbon nanotube gas sensor arrays get selective
Via: nanotechweb.org (link)
Multi-walled carbon nanotubes (MWCNTs) have been widely reported as effective and highly sensitive chemical and biological sensors. However, imparting selectivity to these sensors has been a major challenge. Reporting their results in the journal Nanotechnology, researchers based at the University of Kentucky, US, have come up with a fabrication scheme that offers good control over the sensitivity of the device and makes the composite films gas-specific. The team has used the approach to develop composite films of MWCNTs and conducting polymers, which can selectively detect reducing and oxidizing agents even at low concentrations.

All Nitrogen in the upstairs labs is now purified to at least zero grade.
A faucet has been added to the acess ultrapure water without going into the cleanroom. Be carefull not to open the tap too much. The flow rate is high. DO NOT DRINK unless you want to die.
Reservations for Photolithography have been split into Solvent hood, Spin coater, and Mask Aligner.
The EBL has had a full PM including new emitter, aperatures and liner tube.
The Room cameras are now password protected. All Faculty and Staff can see Brian for a password.
Software updates on the AFM's and QCM-D have really made the instruments more user friendly.
ALD now has the capibility of having up to 3 precursors. One slot is avaible. See Brian or Chuck to add yours.
The temperature controllers on the ovens are drooping like flys. Feel free to silde a temp controller from one oven and place it in another. Press down on the textured sides of the controller to pull it out.
There was a great QCM-D training class conducted by Qsense. Please see Brian for a copy of the presentation. Or go to the QCM-D web page here .
CeNSE participated in the Flat Stanley (www.flatstanley.com) program as a part of it outreach program. Students make paper Flat Stanleys and begin a journal with him for a few days. Then Flat Stanley and the journal are sent to another school where students there treat Flat Stanley as a guest and complete the journal. Flat Stanley and the journal are then returned to the original sender. Students can plot his travels on maps and share the contents of the journal. Often, a Flat Stanley returns with a pin or postcard from his visit. Some teachers prefer to use e-mail only. Especially creative hosts send the Flat Stanleys back with pictures, souvenirs, stories and reminders of the visit. Brian ued the Eletron Beam Lithography tool to draw a picture of Flat Stanley and sent it to Mrs Engstrom's 3rd grade class at Barrie Elementry in Fort Atkinson Wisconsin. See below:
We are beta testing the Live cameras in the labs. Go to http://www.engr.uky.edu/~cense/equipment/equipment.html and click on the links near the bottom of the page.
All calendar requests should be made using the cancelation form found at http://www.engr.uky.edu/~cense/equipment/cancelresform.html
The Center now has a Gold sputter target available. Proposed costs are 200nm is $60 above normal tool use rates. Gold coating 10-50 Angstroms is $20 above normal tool useage rates.

CeNSE Engineering Student is Goldwater Scholar
LEXINGTON, Ky. (April 25, 2008) − Sam Nicaise, a University of Kentucky junior majoring in electrical engineering, has won a Barry M. Goldwater Scholarship worth about $7,500 per year for two years as he completes his undergraduate study.
Nicaise, the son of Susan Mospens and Kurt Nicaise of Covington, was one of 321 students nationwide awarded the prestigious Goldwater Scholarship this year. He is one of only 52 of the scholars majoring in engineering.
"Mr. Nicaise is highly deserving of this honor," said Thomas W. Lester, dean of the UK College of Engineering. "He's compiled a stellar academic record in a rigorous discipline, electrical engineering, while at the same time getting a jump start as a researcher as an undergraduate assistant to Dr. Vijay Singh in the Center for Nanoscale Science and Engineering at UK. He is an outstanding representative of the college and university."
The Goldwater Scholars were selected on the basis of academic merit from a field of 1,035 mathematics, science and engineering students who were nominated by the faculties of colleges and universities nationwide.
The one and two year scholarships cover expenses for tuition, fees, books, and room and board up to a maximum of $7,500 per year for students pursuing careers in mathematics and the natural sciences, as well as many engineering fields.
The junior was pleased to be selected for the scholarship. "I never expected to receive an award of this caliber," says Nicaise. "I feel like it directly reflects the hard work I have put into engineering as an undergraduate student."
As a Goldwater Scholar, Nicaise will channel his passion for math and engineering into participating in or conducting research. The scholars' research work is expected to make a significant technical contribution to science and mathematics.
Nicaise, a 2005 graduate of Holmes High School, began working his freshman year of college as an undergraduate researcher under the direction of UK's Vijay Singh, the Earl Parker Robinson Chair in Engineering in the Department of Electrical and Computer Engineering (ECE).
"This has been an amazing opportunity allowing me to gain experience working in the field, interacting with students of broad backgrounds, and broadening my horizons," says Nicaise.
The Goldwater Scholar credits a number of faculty for his success. Nicaise is grateful to Singh and ECE senior research scientist Suresh Rajaputra for the support and intellectual guidance they have provided. As well, Nicaise says he is inspired to work toward greatness because of the care Todd Hastings, assistant professor of electrical engineering, demonstrates for him and his fellow students.
Nicaise's camping experience as a Boy Scout inspired him to look for ways to help protect the beauty and vitality of Earth, influencing him to pursue studies and a career in renewable energies. His co-op position last year with GE Energy Wind Turbine Systems cemented that interest. "There (GE) I realized that the world of renewable energy is growing by leaps and bounds, but is still young," notes Nicaise. "I found that there is much to be done before we will be able to solve our world's energy needs. I want to be part of that solution."
A Presidential Scholar, Nicaise is currently vice chair of the UK Institute of Electrical and Electronics Engineers and a member of the university's Solar Car Team. He is also a recipient of the Don Conrad Scholarship and the Carl and Jody Kelly Scholarship. Nicaise was also the winner of the Romanowitz Award for the most outstanding electrical engineering junior for 2006-2007.
Outside of the world of engineering, Nicaise is enthusiastic about his recent German courses and hopes to one day be fluent in the language. He is also thankful to be a member of Phi Kappa Tau, which he credits for helping define his character. Nicaise's summer plans include a second year as a resident adviser with the Kentucky Governor's Scholar Program, which he participated in as a high school student.
This fall, Nicaise will take a co-op position with customKYnetics located in Versailles, Ky.
Upon graduation in 2010, Nicaise plans to pursue a master's degree in electrical engineering and a doctorate in engineering. He plans to focus his work in renewable energies in the field of nanotechnology.
The Barry M. Goldwater Scholarship and Excellence in Education Program was authorized by Congress in 1986 to honor the former Arizona U.S. Senator who served the nation for 30 years. In its 20-year history, 5,523 scholarships worth approximately $54 million have been awarded.
A very special thanks to Dane Sievers from Department of Electrical and Computer Engineering at University of Illinois Urbana-Champaign. He provided three manuals, about a thousand pages, for the Prometrix Film Thickness system. The lowest price we could find commercially was $250 for only one of the three manuals. The amount of time it saved CeNSE is immeasurable.
No April fools! Nanopizza was a success. Three students recieved their Nanotechnology certificates. Congrats!

The new clean room is operational. Beware following good cleanroom practices will be enforced ruthlessly.
A problem with the electron optics board on the EBL means it will be down for 2 weeks while a new board is shipped in and installed.
The move of equipment from the old cleanroom to the new one has begun. All annealing furnaces will be down for two weeks. We hope to have the mask aligner and spinners up before the 24th.
Debra Faulk has come on board to be our Executive Assitant. Welcome Debra!
You can now see the status of all of CeNSE's equipment on one page. http://www.engr.uky.edu/~cense/equipment/availability.html Green means the tool is up and available for use. Yellow means some functions of the equipment are avaialable and you should contact me at email@example.com for more information. Red means the equipment is down for repairs.
