Improving battery performance with sand Researchers at the University of California, Riverside’s Bourns College of Engineering have created a lithium ion battery that outperforms the current industry standard by three times using sand as the key material. The researchers, who said this is a low cost, non-toxic, environmentally-friendly way to produce high performance lithium ion battery a... » read more

In the quest to build gadgets that can survive the abuse, engineers have been testing electronic systems based on new materials that are both flexible and switchable – that is, capable of toggling between two electrical states: on-off, one-zero, the binary commands that can program all things digital. At the same time, three Stanford researchers believe that they’ve discovered just such ... » read more

PiezoFET debuts The University of Twente MESA+ Research Institute and SolMateS have put a new twist on the finFET. A piezoelectric stressor layer has been deposited around the finFET, thereby enabling what researchers call the PiezoFET. The PiezoFET could enable steep sub-threshold slope devices. In the lab, this device was also able to reduce the leakage by a factor of five. [caption id... » read more

Battery captures waste heat, converts it to electricity While vast amounts of excess heat are generated by industrial processes and by electric power plants, researchers around the world have spent decades looking for ways to harness some of this wasted energy, according to engineering researchers at Stanford and MIT. They pointed out that most of these efforts have focused on thermoelectric d... » read more

Re-routing noise away from measurement Today, we are capable of measuring the position of an object with unprecedented accuracy, but quantum physics and the Heisenberg uncertainty principle place fundamental limits on our ability to measure. Noise that arises as a result of the quantum nature of the fields used to make those measurements imposes what is called the "standard quantum limit," whi... » read more

Making game play more engaging Engineers at Stanford University have developed what could be the next big thing in interactive gaming: handheld game controllers that measure the player's physiology and alter the game play to make it more engaging. The prototype controller was born from research conducted in the lab of Gregory Kovacs, a professor of electrical engineering at Stanford, in collab... » read more

Making cheap diamonds Graphite and diamonds are two forms of the same element--carbon. In graphite, carbon atoms are arranged in planar sheets and the material is soft. On the other hand, diamonds consist of carbon atoms that are bonded in all directions, making these structures extremely hard. [caption id="attachment_11311" align="alignleft" width="150"] This illustration shows four layers... » read more

Proving the Big Bang theory A team of cosmologists using the BICEP2 telescope at the South Pole have discovered the first direct evidence of the Big Bang theory. The team includes Harvard University, the University of Minnesota, the California Institute of Technology/Jet Propulsion Laboratory, Stanford University/SLAC and others. Using the BICEP2, researchers found direct evidence of a cosm... » read more

Bending light with a tiny chip Imagine your smartphone being able to project a bright, clear image from a presentation or a video onto a wall or a big screen – all made possible with a light-bending silicon chip developed by Caltech researchers. Traditional projectors pass a beam of light through a tiny image, using lenses to map each point of the small picture to corresponding, yet expan... » read more
