Biosensor Could Improve Lives of People with Neurological Brain Disorders
An engineering researcher at the University of Arkansas has developed a wireless, implantable biosensor that may one day help physicians treat patients with neurological brain disorders such as Parkinson's Disease, Alzheimer's Disease and epilepsy. Made of carbon nanotubes, the sensor monitors and controls chemicals in the brain and communicates with other sensors to control tremors or direct the movement of prosthetic limbs.
UA Researchers Create Biodiesel Fuel from Chicken Fat
In the future, fat shaved off chicken breasts and other parts may power automobiles that emit less pollution.
UA Researcher Puts Gas Under Pressure for Supercritical Fluid Extraction
On his laboratory desk, University of Arkansas researcher Jerry King has a small display with three vials. The first vial contains small chocolate candies. Another vial is three-quarters full of the cream-colored, liquid fat he extracted from the candies. The third vial contains shrunken balls of chocolate without fat.
System Will Provide Sharp, 3-D Images of Breast Tumors
University of Arkansas engineering researchers have designed and built the archetype of a microwave-imaging system that could lead to a new method of breast-cancer detection. The system applies the same principles and technology used to detect buried land mines.
Staying Cool: Research Shows How Spray Cooling Works
Heat is a critical obstacle to developing smaller electronic devices. Engineering researchers at the University of Arkansas have developed computer models that explain the complex process of spray cooling, an increasingly popular method used to remove heat from microsystems in computers and other electronic devices. The research could lead to further development of even smaller microscopic electronic systems, circuits and chips.
Engineering Researcher Builds Water-Filtration System in Rural Colombia
A University of Arkansas researcher used his engineering expertise to provide clean water to an Amazon village this summer and will help build clean water systems in Indonesia this fall. The latter project is part of a large redevelopment of areas that were destroyed by last year's tsunami.
From Ditch to Delight: Movement Gives `Daylight' to Lost Streams, Improves Water Quality
As American cities developed, many streams and rivers flowing through them were buried underground, channeled into huge pipes or relegated to concrete ditches in out-of-sight areas. Today, cities across the country have discovered the economic and ecological value of those streams and have begun to return them to a man-made version of their original, natural state.
UA Researchers Using Arkansas’ First Supercomputer
Researchers at the University of Arkansas have already produced results using Red Diamond, the state's first supercomputer, and they have plans for more -- developing the molecular structures of potential new drugs, examining tornados and volcanoes, and modeling global climate change. The machine boasts a cluster of 128 dual-processor computers and operates approximately 256 times faster than the typical new desktop computer.
