Brain chips Pennsylvania State University has developed a technology that could enable futuristic biochips, namely those that mimic the human brain. In the lab, Penn State combined a thin film of vanadium dioxide (VO2) on a titanium dioxide substrate to create an oscillating switch. VO2 is an exotic material that exhibits semiconductor-to-metal transitions at 68 °C. In the R&D stage fo... » 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

Making flexible carbon nanotube circuits more reliable and efficient Engineers would love to create flexible electronic devices, such as e-readers that could be folded to fit into a pocket with one such approach involving designing circuits based on electronic fibers known as carbon nanotubes (CNTs) instead of rigid silicon chips -- but reliability is essential. Given that most silicon chip... » read more

Why Would IBM Sell Its Semi Group?
By Ed Sperling - 20 Feb, 2014 - Comments: 1

Rumors are always just rumors until proven otherwise in business, but in the case of IBM’s semiconductor business, hints about the sale of its semiconductor business are particularly noteworthy. Much has changed since the days when IBM—as International Business Machines—went head-to-head with AT&T’s quasi-public Bell Labs and Xerox’s Palo Alto Research Center (PARC). The breakup of... » read more

Outperforming copper Carbon nanotube-based fibers invented at Rice University have greater capacity to carry electrical current than copper cables of the same mass -- on a pound-per-pound basis -- according to new research. While individual nanotubes are capable of transmitting nearly 1,000 times more current than copper, the same tubes coalesced into a fiber using other technologies fail l... » read more

Ballistic transport in graphene Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room temperature in a process known as ballistic transport, according to researchers at Georgia Tech. Ballistic transport is the process by which electrical res... » read more

E-whiskers From the world of nanotechnology, researchers with Berkeley Lab and UC Berkeley are on the verge of electronic whiskers -- tactile sensors from composite films of carbon nanotubes and silver nanoparticles similar to the highly sensitive whiskers of cats and rats. These new e-whiskers respond to pressure as slight as a single Pascal, which is about the amount of pressure exerted o... » read more
