A team of Columbia Engineering researchers, led by Mechanical Engineering Professor James Hone and Electrical Engineering Professor Kenneth Shepard, has taken advantage of graphene's special properties—its mechanical strength ...
New calculations shows that the influence of quantum effects on the operating conditions of nanodevices has, until now, been overestimated.
Plasma is one of the four fundamental states of matter, alongside solid, liquid and gas. Ubiquitous in form, plasma is an ionised gas so energised that electrons have the capacity to break free from their nucleus.
Scientist Davide Iannuzzi and his team have developed a method to place novel miniaturised mechanical devices on the tips of optical fibres. The technology has many applications, such as providing a new generation of small, ...
Earthquake early warning systems may provide the public with crucial seconds to prepare for severe shaking. For California, a new study suggests upgrading current technology and relocating some seismic stations would improve ...
Microelectromechanical systems, known as MEMS, are ubiquitous in modern military systems such as gyroscopes for navigation, tiny microphones for lightweight radios, and medical biosensors for assessing the wounded. Such applications ...
Long-distance communication increasingly relies on networks of fiber-optic cables that carry data encoded in nimble beams of light. Conventional computer circuits, however, still use relatively sluggish electronic circuits ...
Electric current sufficient to light a string of LEDs, activate an e-paper display or even trigger action by a computer can be generated by tapping or rubbing simple, flexible generators made of paper, thin sheets of plastic ...
A Georgia Tech-led research team has been awarded a $2 million grant from the National Science Foundation (NSF) to develop a unique approach to making extremely compact and highly efficient antennas and electronics. The new ...
A tiny chip used in smart phones to adjust the orientation of the screen could serve to create a real-time urban seismic network, easily increasing the amount of strong motion data collected during a large earthquake, according ...
