In the ever-shrinking world of electronics, vacuum tubes long ago gave way to solid-state component transistors, then to transistors in integrated circuits. Last year an international team achieved the next astonishing milestone in downsizing: They devised a way to make a single-atom transistor, the smallest possible electronic switch.
This coveted award is a mark of great distinction for a college chapter. Chapters are judged on their activities of service to others, and all chapters with exemplary programs can win.
A new agricultural electronic insect trapping device has the potential to automatically monitor insect pest populations and reduce the amount of insecticides emitted into the environment.
A new type of transistor shaped like a Christmas tree has arrived just in time for the holidays, but the prototype won't be nestled under the tree along with the other gifts.
People can let their fingers - and hands - do the talking with a new touch-activated system that projects onto walls and other surfaces and allows users to interact with their environment and each other.
Scotch tape, a versatile household staple and a mainstay of holiday gift-wrapping, may have a new scientific application as a shape-changing "smart material."
Purdue University is participating in an international effort led by Drexel University to create robots that could respond to disasters, including those involving radioactive or bio-contamination hazards.
