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.
Petrologist Jim Hower and Eastern Kentucky Regional Coordinator Greg Copley are assisting Jon Thorson, UK Pharmacy, in locating and sampling extreme environments in Kentucky. Such sites include soils associated with coal mine fires; waters associated with swamps, sulfur springs, acid mine drainage; and the spoils from lead and zinc mining. Thorson’s research group is hoping to isolate previously unknown antibiotics and other drugs from microorganisms in the environment. Recent sampling took place in Owen and Henry Counties.
Here Madan Kharel (Pharmacy) is obtaining a sample while CAER's John Hiett stands ready to assist.
Congratulations to Rachel Hatch, M.S. candidate, who was just awarded a $2,000 graduate student grant from the Geological Society of America for her proposal entitled: “Effects of petroleum hydrocarbon exposure following the Deepwater Horizon spill on tidal marsh sedimentary and biological processes: An investigation using radioisotopes and benthic foraminifera.”
Rachel worked in the petrology lab for two years as an undergraduate.
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.
