Fundamental chemistry findings could help extend Moore's Law

17-07-2014

Over the years, computer chips have gotten smaller thanks to advances in materials science and manufacturing technologies. This march of progress, the doubling of transistors on a microprocessor roughly every two years, is called Moore's Law. But there's one component of the chip-making process ...

Strongly interacting electrons in wacky oxide synchronize to work like the brain

19-05-2014

Current computing is based on binary logic - zeroes and ones - also called Boolean computing, but a new type of computing architecture stores information in the frequencies and phases of periodic signals and could work more like the human brain using a fraction of the energy necessary for today's ...

Carbon's new champion

Rice U. theorists calculate atom-thick carbyne chains may be strongest material ever

18-10-2013

Carbyne will be the strongest of a new class of microscopic materials if and when anyone can make it in bulk. If they do, they'll find carbyne nanorods or nanoropes have a host of remarkable and useful properties, as described in a new paper by Rice University theoretical physicist Boris Yakobson ...

'Amplified' nanotubes may power the future

19-07-2011

Rice University scientists have achieved a pivotal breakthrough in the development of a cable that will make an efficient electric grid of the future possible.Armchair quantum wire (AQW) will be a weave of metallic nanotubes that can carry electricity with negligible loss over long distances. It ...

Quartz crystal microbalances enable new microscale analytic technique

30-11-2010

A new chemical analysis technique developed by a research group at the National Institute of Standards and Technology (NIST) uses the shifting ultrasonic pitch of a small quartz crystal to test the purity of only a few micrograms of material. Since it works with samples close to a thousand times ...

Sugar and slice make graphene real nice

Rice University lab finds table sugar, metallic sheets produce pristine graphene in one step

17-11-2010

Future computers may run a little sweeter, thanks to a refinement in the manufacture of graphene at Rice University. Rice researchers have learned to make pristine sheets of graphene, the one-atom-thick form of carbon, from plain table sugar and other carbon-based substances. They do so in a ...
