In the hands of jewelers, gold can be fashioned into rings and pendants of long-lasting beauty. But, when reduced in size to nanocrystals containing a few thousand atoms, this noble metal is a surprisingly good catalyst.
The universe as we currently know it is made up of three dimensions of space and one of time, but researchers in the Department of Physics and the Department of Electrical and Computer Engineering at Virginia Tech are exploring the possibility of an extra dimension.
University of Maryland research that started with bacteria from the Chesapeake Bay has led to a process that may be able to convert large volumes of all kinds of plant products, from leftover brewer's mash to paper trash, into ethanol and other biofuel alternatives to gasoline.
A researcher at the National University at San Diego has taken a mathematical approach to a biological problem - how to design a portable DNA detector. Writing in the International Journal of Nanotechnology, he describes a mathematical simulation to show how a new type of nanoscale transistor might be coupled to a DNA sensor system to produce a characteristic signal for specific DNA fragments in a sample.
Global Warming may soon affect every mode of transportation worldwide. With rising sea levels alongside increased, more intense storms, current transportation infrastructures may be seriously weakened, the National Research Council says.
