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

Silicon oxide memories Thanks to a refinement that will allow manufacturers to fabricate devices at room temperature with conventional production methods, Rice University’s silicon oxide technology for high-density, next-generation computer memory is one step closer to mass production. Rice’s silicon oxide memories are a type of two-terminal, “resistive random-access memory” (RRAM) ... » read more

Carbon nanotubes “unzipped” into graphene nanoribbons by a chemical process invented at Rice University are finding use in all kinds of projects, but Rice scientists have now found a chemical-free way to unzip them. A Rice materials scientist discovered that nanotubes that hit a target end first turn into mostly ragged clumps of atoms, but nanotubes that happen to broadside the target un... » 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

Nanotubes boost terahertz detectors Researchers at Rice University, Sandia National Laboratories and the Tokyo Institute of Technology have developed novel terahertz detectors based on carbon nanotubes that could improve medical imaging, airport passenger screening, food inspection and other applications. Unlike current terahertz detectors, the devices are flexible, sensitive to polarizatio... » read more

Lithium-free flexible battery A Rice University laboratory has flexible, portable and wearable electronics in its sights with the creation of a thin film for energy storage. The researchers have developed a flexible material with nanoporous nickel-fluoride electrodes layered around a solid electrolyte to deliver battery-like supercapacitor performance that combines the best qualities of a h... » 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

Speeding Access To Information Big data today is usually stored on multiple hard disks on a number of machines across an Ethernet network, but this storage architecture considerably increases the time it takes to access the information. Researchers at MIT have developed a storage system for big-data analytics they claim can dramatically reduce the time it takes to access information. The sy... » read more

Do Students Need More Formal Education?
By Brian Bailey - 21 Nov, 2013 - Comments: 0

A few weeks ago, some of the top researchers and practitioners in the area of formal methods converged on Portland, Oregon. The event was the annual Formal Methods in Computer-Aided Design (FMCAD) conference and Semiconductor Engineering attended the panel titled “Teaching Formal Methods: Needs, Challenges, Experiences, and Opportunities.” Panelists included: Jason Baumgartner, formal verif... » read more

Cracking The Tough Nut Using Formal Methods
By Brian Bailey - 21 Nov, 2013 - Comments: 1

Pranav Ashar, CTO of Real Intent, assured a packed room of researchers and practitioners of formal methods at the recent FMCAD conference: “Static verification is being used in the verification of designs. Every major chip out there is using static methods for sign-off today.” He used an analogy of cracking a nut. “There’s a right way and a wrong way and if you don’t pick the right me... » read more
