In the search for low-cost color displays that do not drain a computer’s battery, the polymer light-emitting electrochemical cell (LEC) may be the next answer to the problem, according to an international team of electrical engineers.
“The color-variable LEC can provide a solution to simple, low cost color displays,” Cheng Huang, graduate student in electrical engineering at Penn State told attendees today (Aug. 20) at the 224th American Chemical Society annual meeting in Boston.
Events like the September 2000 discovery of biologically engineered corn in fast food tortillas have focused media attention and stirred controversy about genetically modified organisms. While new approaches in agricultural biotechnology have improved crop quality and yield, the incorporation of genes from other organisms into food plants has raised concerns about possible health risks and environmental consequences. A new report from the American Academy of Microbiology (AAM) looks at the case of a
A new way researchers have developed to make dense ceramics in complex shapes could lead to light, tough, and hard ceramic parts at lower cost.
The recently patented technique, called “displacive compensation of porosity,” or DCP, uses a chemical reaction between molten metal and a porous ceramic to generate a new composite material. The technique fills the tiny pores inside the ceramic with additional ceramic material. The resulting super-dense part retains the shape of the original ceramic
DNA of Xenopus tropicalis will provide new clues to vertebrate development
In their continuing search for new clues to how human genes function and how vertebrates develop and evolve, researchers at the U.S. Department of Energy’s Joint Genome Institute (JGI) are gearing up to map the DNA of a diminutive, fast-growing African frog named Xenopus tropicalis .
Frogs have long been a favorite subject for biologists because their growth from eggs to tadpoles to
Researchers are developing a marijuana-derived synthetic compound to relieve pain and inflammation without the mood-altering side effects associated with other marijuana based drugs.
They say the compound could improve treatment of a variety of conditions, inctluding chronic pain, arthritis and multiple sclerosis. Their findings were presented at the 224th national meeting of the American Chemical Society, the world’s largest scientific society.
The compound, called ajulemic
A compound found in many foods and drinks could form the basis for new drugs to defeat cancer and heart disease, scientists at UCL claimed today.
Professor Peter Shepherd and his team believe that caffeine and theophylline- compounds commonly found in cola beverages, coffee, tea and chocolate – block the operation of a key enzyme linked to a wide range of cell functions. This suggests these compounds would block cell growth and also blood clotting. The teams work may also explain the anti-in
