Nanocrystal conductors could lead to massive, robust 3-D storage Rice University scientists have created the first two-terminal memory chips that use only silicon, one of the most common substances on the planet, in a way that should be easily adaptable to nanoelectronic manufacturing techniques and promises to extend the limits of miniaturization subject to Moore's Law. Last year, researchers in the lab of Rice Professor James Tour showed how electrical current could repeatedly break and...

Rice researchers show environmentally friendly ways to make it in bulk, break it down "We can make you and we can break you." If Rice University scientists wrote country songs, their ode to graphene oxide would start something like that. But this song wouldn't break anybody's heart. A new paper from the lab of Rice chemist James Tour demonstrates an environmentally friendly way to make bulk quantities of graphene oxide (GO), an insulating version of single-atom-thick graphene expected to find...

Rice, Korean collaboration produces printable tag Long lines at store checkouts could be history if a new technology created in part at Rice University comes to pass. Rice researchers, in collaboration with a team led by Gyou-jin Cho at Sunchon National University in Korea, have come up with an inexpensive, printable transmitter that can be invisibly embedded in packaging. It would allow a customer to walk a cart full of groceries or other goods past a scanner on the way to the car; the...

Researchers simplify fabrication of nano storage, chip-design tools Advances by the Rice University lab of James Tour have brought graphite's potential as a mass data storage medium a step closer to reality and created the potential for reprogrammable gate arrays that could bring about a revolution in integrated circuit logic design. In a paper published in the online journal ACS Nano, Tour and postdoctoral associate Alexander Sinitskii show how they've used industry-standard lithographic...

Scientists at Rice University and North Carolina State University have found a method of attaching molecules to semiconducting silicon that may help manufacturers reach beyond the current limits of Moore's Law as they make microprocessors both smaller and more powerful.Their findings are published this month by the Journal of the American Chemical Society.Moore's Law, suggested by Intel co-founder Gordon Moore in 1965, said the number of transistors that can be placed on an integrated circuit...

Scientists at Rice University have found a simple way to create basic elements for aircraft, flat-screen TVs, electronics and other products that incorporate sheets of tough, electrically conductive material. And the process begins with a zipper. Research by the Rice University lab of Professor James Tour, featured on the cover of the April 16 issue of the journal Nature, has uncovered a room-temperature chemical process that splits, or unzips, carbon nanotubes to make flat nanoribbons. The...

This year's model isn't your father's nanocar. It runs cool.The drivers of Rice University's nanocars were surprised to find modified versions of their creation have the ability to roll at room temperature. While practical applications for the tiny machines may be years away, the breakthrough suggests they'll be easier to adapt to a wider range of uses than the originals, which had to be heated to 200 degrees Celsius before they could move across a surface.The nanocar was a sensation when...

Rice University scientists have constructed the world's smallest car -- a single molecule "nanocar" that contains a chassis, axles and four buckyball wheels. The "nanocar" is described in a research paper that is available online and due to appear in an upcoming issue of the journal Nano Letters. "The synthesis and testing of nanocars and other molecular machines is providing critical insight in our investigations of bottom-up molecular manufacturing," said one of the two lead researchers,...
