For several years CAER havs been part of KYNEED's bigger area tour for science teachers. The two day travels include power plants, mines, Locust Trace Elementary, etc. The group gets a close up view and explanation of carbon dioxide capture, biofuel energy, and how coal ash can be recycled into useable products instead of land filled at CAER.
Dr. Steve Lipka, CAER Associate Director for Electrochemical Power Sources, has been awarded a 2 year, $389,000 grant from The National Institute for Occupational Safety and Health (NIOSH). The title of the project is “Evaluating the Inherent Safety of Lithium-ion Batteries in Portable Electronics Used in Underground Mine Environments.”
This project will help to understand the safety of Li-ion battery chemistries used in portable electronic devices such as hand-held gas detectors, cap lamps, hand tools, communications devices, and tracking devices and their potential risk as an ignition source in an underground mine where there is a mixture of methane and air. In a catastrophic event, the battery can sustain mechanical damage, resulting in reactions between active battery materials and the highly volatile and flammable organic electrolyte. These reactions can result in rising cell temperatures which accelerate further chemical reactions in the battery causing heat and gas generation. The project will evaluate the ignition potential of various Li-ion battery chemistries in both cylindrical and prismatic cell formats in a simulated underground mine environment under mechanical damage.
Lipka’s group will recommend safer lithium-ion battery chemistries and use in portable devices. The researchers will also develop strategies to stop or reduce potential ignition for lithium-ion batteries used in underground mines.
Professor Thomas Novak of UK’s Department of Mining Engineering will serve as a project consultant.
CAER researchers Anne Oberlink and Liz Harman-Ware reached out to high school girls at the EKU Girls’ STEM Day recently. The scientists were accompanied by two high girls who recently toured CAER. STEM practitioners and educators led girls through activities that mirror real-world STEM tasks and highlight creative and innovative problem solving. Anne and Liz exhibited and served as mentors.

On March second Marsha Grimminger, of the Electrochemistry Group, designed questions related to a science challenge geared toward high school chemistry students for Bluegrass Community and Technical College's Regional Science Olympiad. They were not told of the specific topic before the event. The 18 students collected data through experimentation and compared results.
Turner Construction Company, a general contractor firm based in Lexington, was recognized for its construction manager involvement with the UK Center for Applied Energy Research (CAER) Renwable Energy Research Lab. The construction of the new 43,000 square foot, high-performance laboratory will lower operation costs of CAER, while increasing education about the numerous energy technologies implemented in the building.
Four local high school students who were mentored by University of Kentucky Center for Applied Energy Research scientists have proved experience gain by working in laboratories with mentors is invaluable.
Valerie Sarge, a junior at Paul Laurence Dunbar High School, placed first in the Energy and Transportation category at the Central Kentucky Regional Science and Engineering Fair, going on to win first place in the same category at the state competition. This qualifies her to go on to Intel’s International Science and Engineering Fair (ISEF) to be held in Phoenix. Valerie was mentored by Chemistry Professor/CAER Faculty Associate, John Anthony. In her work with the solar energy group she is using organic compounds called furan-based materials. These can be derived from agricultural waste products to create new semiconductors for use in low-cost solar cells. She is has been working on synthesis, but may soon move toward creating solar cells.
Will Kimmerer, a ninth grader at Sayre School, won top awards at the regional and state fairs in the Environmental Science category, including second in the Physical Sciences category. Kimmerer is interested in water purification and obtained carbon material samples for use in his project from CAER working closely with Director Rodney Andrews during the project. He was selected for the I-SWEEP 2013 conference (International Sustainable World Energy Engineering Environment Project) in Houston, where he will present his work. Additionally, he was selected for the Stockholm Junior Water Award.
Additionally, two Dunbar CAER interns placed well at the regional level and went on to compete at the state competition. Rohin Lohe placed first in the "Engineering: Materials and Bioengineering" category, and went on to place third at the state competition. Lohe will compete at the Kentucky Junior Academy of Sciences on April 27th. John Luan also won in the “Energy and Transportation” category at regionals.
Matt Weisenberger, Associate Director for Carbon Materials, is mentoring Lohe with a project titled "Finite Element Analysis of Heat Conduction through Interfaces: Modeling and Experimental Verification with Stainless Steel, Copper, and Multiwall Carbon Nanotube Arrays as Thermal Interface Materials." Lohe has been conducting his research at the UK CAER laboratory facilities and working directly with the Carbon Materials Research staff in completing the tests.
Finally, Lohe’s project included part of the expertise gained while working with CAER’s Electrochemical Power Sources group under the direction of Associate Director Steve Lipka. John is working on a project entitled “Carbon-based Capacitive Thin Films for AC Line Filtering” in which the goal is to demonstrate whether carbon-based supercapacitors can be used as a lower-cost, more-dependable replacement for traditional electrolytic capacitors in electronic devices.

John Luan, a Dunbar High School student, who is interning with the Electrochemical and Power Systems UK CAER Research group, recently won at a local science fair in the Energy and Transportation category. He will advance to the next level of competition. John's project included part of his expertise earned while working in the Electochemistry research group.
The Kentucky-Argonne Battery Manufacturing Research and Development Center was toured recently by journalists. The Kentucky FAMiliarization Tour is sponsored by the Cabinet of Economic Development. It is made up of professional writers from around the world who are interested in the automotive industry and related manufacturing. They visited Kentucky as guests of Governor Beshear and toured the highlights of the state such as Ford, Toyota, UPS, and the Battery Center. The goal is to give them story information for future publications.
