Engineers address heat issues in 3-D integrated circuits
A team of UT Arlington researchers, funded by the National Science Foundation, is working to minimize and dissipate the heat generated by three-dimensional integrated circuits.
Ankur Jain, assistant professor of mechanical and aerospace engineering, is working on the project with Dereje Agonafer, Jenkins Garrett Professor of Mechanical and Aerospace Engineering, and Roger Schmidt, IBM fellow and chief engineer.
“There is only a very limited amount of space available on an integrated circuit so we’ve had to build vertically, placing wafers on top of wafers,” Dr. Jain says. “These 3-D integrated circuits have led to significant performance improvements. However, when we stack these circuits on top of each other, heat starts to become a problem. All the heat being generated in this multi-layer stack needs to be removed, otherwise it causes deterioration in performance.”

Research yields new ion analyzing technique
Sandy Dasgupta's work to develop a more efficient, effective way of measuring ions in solution has led to a new device in the scientific marketplace that could improve water quality testing and manufacturing methods.
Dr. Dasgupta, the Jenkins Garrett Professor of Chemistry and Biochemistry, invented the charge detector for ion chromatography, along with Bingcheng Yang, a member of his research group, and Kannan Srinivasan, technical director for Thermo Fisher Scientific Inc.
The U.S. Patent and Trademark Office recently assigned a patent for the new technology to the UT System Board of Regents and Dionex Corporation, which is based in Sunnyvale, Calif. Thermo Fisher is Dionex’s parent company.
“The fact that ions carry a charge has been known since before the 20th century began," Dasgupta says. "For the first time, we can now measure that charge in a solution."

Civil engineers increase energy created from solid waste
Two UT Arlington civil engineering professors are working with a new imaging system that has doubled the amount of methane gas produced by the city of Denton landfill that is converted to energy.
The landfill is the first in Texas to implement the Enhanced Leachate Recirculation system. The gas now provides power for about 1,500 Denton households. However, with increased efficiency of ELR operation, the system will be able to power 3,000 homes in the city of 117,000, officials say.
Sahadat Hossain and Melanie Sattler, associate professors of civil engineering, helped the city of Denton increase the efficiency of its landfill operation.
Jean-Pierre Bardet, dean of the College of Engineering, says the work by Hossain and Sattler holds promising results for municipalities worldwide.
“This is the kind of innovation that will help cities harness available energy resources and maximize the utilization of available spaces at a time of unprecedented urban growth,” Dr. Bardet says.

Biology professor studying microbial losses in Amazon's deforestation
Research from an international team of microbiologists, including professors from UT Arlington, has revealed a new concern about deforestation in the Amazon rainforest—a troubling net loss in diversity among the microbial organisms responsible for a functioning ecosystem.
“We have known for a long time that conversion of rainforest land in the Amazon for agriculture results in a loss of biodiversity in plants and animals," says Jorge Rodrigues, assistant professor of biology, who was part of the research team and is first author on a recent publication of the findings. "Now we know that microbial communities which are so important to the ecosystem also suffer significant losses.”
The research, “Conversion of the Amazon rainforest to agriculture results in biotic homogenization of soil bacterial communities,” is described in the Proceedings of the National Academy of Sciences.

Academic advising conference set for Feb. 11
“Advising Tune-Up: Becoming Mechanics for Student Success” is the theme for the 16th annual UT Arlington Academic Advising Association conference Monday, Feb. 11, in the E.H. Hereford University Center.
Keynote speaker is Jennifer Joslin, director of the Office of Academic Advising at the University of Oregon and a member of the National Academic Advising Association board of directors. She is co-author of Academic Advising Administration: Essential Knowledge and Skills for the 21st Century.
Conference and registration information is online. Registration and payment deadline is Friday, Feb. 1.
Tuesday is deadline for spring break advisers
Staff or faculty advisers are needed for alternative spring break trips March 10-15, planned by the Alternative Breaks program in the Department of University Events. Alternative spring break allows students to serve as volunteers for issues such as the environment, urban poverty, and homelessness.
Advisers would work with groups of eight to 17 students. All trip fees are waived for advisers. Applications are online and available in the Student Activities office, Room B140 in the E.H. Hereford University Center. The deadline to apply is Tuesday, Jan. 8.
Railroad crossings closed next week
Plan for railroad crossing closures while Union Pacific improves tracks through Arlington.
Railroad crossings between Division and Abram streets at Bowen Road, Davis Drive, Cooper Street, Center Street, Mesquite Street, Collins Street, and Stadium Drive will be closed Jan. 16-24.
Starting Jan. 16, crossings beginning at Bowen and moving east will close. Davis is expected to close Jan. 17, with Cooper, Center, and Mesquite closing Jan. 18, at which point five railroad crossings will be closed at one time. As the project continues to move east, Union Pacific plans to open Bowen before closing Collins and open Davis before closing Stadium.
Available north-south routes within the city limits are Green Oaks Boulevard, Forest Edge Drive, Fielder Road, West Street, and Texas Highway 360. West starts behind the E.H. Hereford University Center and runs north through downtown Arlington, connecting to Division. Fielder, Forest Edge, and Green Oaks are west of campus.
Architecture and Fine Arts Library closed
The Architecture and Fine Arts Library is closed for construction through Tuesday, Jan. 8.
For more information or to contact staff members, call 2-2387.
Reminder for reviews and updates through UT Direct
Now is the time for faculty and staff to verify whether their UT EID is active.
The UT EID provides access to UT Direct online, which allows you to review your mailing address for the W-2 mailing and other University mailouts, and to obtain your W-2 when it becomes available later this month.
In addition, you can review your earnings statement, review/update your tax withholding (W-4), review your insurance and retirement elections, and update personal biographical information that includes phone numbers, email address, and emergency contacts.
Note that if the UT EID is not used within 45 days, it must be re-activated by emailing firstname.lastname@example.org from your UT Arlington email account.
