A team of researchers has observed unusually long-lived wavelike electrons called 'plasmons' in a new class of electronically conducting material. Plasmons are very important for determining the optical and electronic properties of metals for the development of new sensors and communication devices.
Additive manufacturing is a technique in which a three-dimensional object is produced by successively adding new layers of building material to those that have already been deposited. Recently, commercially available 3-D printers have been experiencing rapid development and so have 3-D-printing materials,
Although we've previously heard about various groups' tiny "microbots," a new one is actually claimed to be the world's smallest microelectronic robot. What's more, it moves by shooting out dual jets of bubbles.
