Making sounds with atoms What is the sound of one hand clapping? Perhaps a better question is what is the sound of an atom? Chalmers University of Technology has demonstrated the ability to make a sound with an atom. More specifically, researchers have made acoustic waves with an artificial atom. In doing so, researchers have demonstrated quantum physics with sound taking on the role of lig... » read more

More Problems Ahead

Revealing the purity of graphene Graphene may be tough, but those who handle it had better be tender, according to researchers from Rice University and Osaka University who have come up with a simple way to spot contaminants given that the environment surrounding the atom-thick carbon material can influence its electronic performance. It is so easy to accidentally introduce impurities into ... » read more

28nm brain chips DARPA-funded researchers have developed a 28nm chip that mimics the brain. The low-power chip is inspired by the neuronal structure of the brain. Designed by researchers at IBM under DARPA’s Systems of Neuromorphic Adaptive Plastic Scalable Electronics (SyNAPSE) program, the chip consists of 5.4 billion transistors. Built on Samsung’s 28nm foundry process, the chip has ... » read more

Plotting IBM Micro’s Future
By Mark LaPedus - 14 Aug, 2014 - Comments: 1

It’s been a wild ride for IBM’s Microelectronics Group. Neither IBM, nor the other parties involved, have made any public comments about the recent events concerning IBM Micro. Much of the drama has played out in the media. Based on those reports, here’s a rough outline of the events. Not long ago, IBM put its loss-ridden chip unit on the block to shore up the company’s bottom lin... » read more

All graphene is not the same Widely touted as the most electrically conductive material ever studied, researchers at the University of Pennsylvania now understand that all graphene is not the same. With so few atoms comprising the entirety of the material, the arrangement of each one has an impact on its overall function. The team has used an advanced microscope to study the relationship be... » read more

Solar-cell efficiency in one step Rice University scientists have created a single-step process for producing highly efficient materials that let the maximum amount of sunlight reach a solar cell. The Rice lab of chemist Andrew Barron found a simple way to etch nanoscale spikes into silicon that allows more than 99 percent of sunlight to reach the cells’ active elements, where it can be t... » read more
