Cobalt atoms on graphene: a low-cost catalyst for producing hydrogen from water

Rice University catalyst may lead to clean, inexpensive hydrogen production for fuel cells
October 23, 2015

A new catalyst just 15 microns thick has proven nearly as effective as platinum-based catalysts but at a much lower cost, according to scientists at Rice University. The catalyst is made of nitrogen-doped graphene with individual cobalt atoms that activate the process. (credit: Tour Group/Rice University)

Graphene doped with nitrogen and augmented with cobalt atoms has proven to be an effective, durable catalyst for the production of hydrogen from water, according to scientists at Rice University.

The Rice University lab of chemist James Tour and colleagues has developed a robust, solid-state catalyst that shows promise to replace expensive platinum for hydrogen generation. (Catalysts can split water into its constituent hydrogen and oxygen atoms, a process… read more

Coaxial ‘nanocable’ could be big boon for energy storage

Could be used to build large-scale energy-storage devices, as components of lab-on-a-chip processors
June 11, 2012

REce_NANOCAPACITOR_Cable

Researchers at Rice University have created a tiny coaxial cable only 100 nanometers wide with higher capacitance than previously reported microcapacitors.

The nanocable,produced with techniques pioneered in the nascent graphene research field, could be used to build next-generation energy-storage systems.

It could also find use in wiring up components of lab-on-a-chip processors.

The tiny coaxial cable is similar in makeup to… read more

Coax goes nano

November 25, 2002

Researchers at Harvard University have made nanoscale wires from layers of different materials using the semiconductor manufacturing processes used to construct computer chips. The nanowires could be used to make faster computer chips, higher-density memory and smaller lasers.

Coatings and arrays help put medication where it’s needed

June 30, 2003

Small tech is helping medicinal molecules such as proteins, peptides, genes and vaccines reach the right destination with greater precision, speed and control.

Researchers are developing devices that can deliver drugs to specific structures within the cell. Others are developing devices to be implanted under a patient’s skin or in the abdomen that would provide tiny, precise doses of hormones, pain medication or other pharmaceuticals on a customizable schedule.… read more

Coated nanotubes make biosensors

December 30, 2004

Researchers from the University of Illinois at Urbana-Champaign are using carbon nanotubes to sense single molecules, and are tapping the way carbon nanotubes give off near-infrared light in order to read what the sensors have detected.

The sensors could eventually be used to monitor biochemical changes in biological fluids and tissue in real time.

Coated nanoparticles slip through mucus

January 23, 2007

Nanoparticles coated with polyethylene glycol can quickly slip through human mucus. The results raise hopes for more efficient delivery of a variety of drugs.

Coat of armour creates hardy ‘super-cells’

April 14, 2008

Giving cells a tough calcium phosphate mineral coat can make them much more robust, Chinese researchers say.

The team has developed such egg-shell-like coats for yeast cells that let them survive longer in harsh environments, entering a state of “suspended animation,” where they did not grow or divide. When the shells were later removed with a weak acid solution, the cells began growing and dividing as normal.

Incorporating… read more

CNN’s Spurlock Inside Man explores extreme life extension

April 18, 2014

(Credit: CNN)

In “Futurism,” an episode in CNN’s original series Morgan Spurlock Inside Man on Sunday April 20, Spurlock enters the “brave new world of extreme life extension, embarking on a life-prolonging regimen and trying everything from genome hacking to creating an avatar and uploading his consciousness in preparation for the ‘Technological Singularity.’

“Spurlock’s quest to live forever includes visits with radical futurist Ray Kurzweil, Stanford University’s Virtual Human Interaction Lab, Cambrian Genomics in San Francisco, North… read more

CMU the favorite in robot race across Mojave

February 23, 2004

On March 13, up to 20 robotic vehicles will compete in a $1 million Grand Challenge race sponsored by the Defense Advanced Research Projects Agency. The winner will be the first machine to cover the still-undisclosed route from somewhere outside Barstow, Calif., to somewhere in the vicinity of Las Vegas within 10 hours.

No robot has ever done anything like this. Never has an autonomous vehicle gone so far,… read more

CMU team to develop a software ‘secretary’

July 18, 2003

Researchers are developing “personalized cognitive assistant” software with $7 million DARPA funding.

Users will be able to establish a degree of trust with this software, just as they do with human assistants or secretaries. It will have to learn enough of the nuances of human interaction that it will know, for instance, when the user can be interrupted.

CMU Robot finds life ‘all by itself’

March 16, 2005

A Carnegie Mellon University rover called Zoe is the first robot to remotely detect life, finding fluorescent signals from both visible lichens and microscopic bacteria in Chile’s barren Atacama Desert.

The NASA-sponsored test thus demonstrated that scientists can use robots to identify life in harsh regions.

The CMU instrument detects life by looking for natural fluorescence from cells that contain chlorophyll. It also can spray four special dyes… read more

CMU researchers develop method to help computer vision systems decipher outdoor scenes

Computer vision systems can struggle to make sense of a single image, but a new method devised by computer scientists at Carnegie Mellon University enables computers to gain a deeper understanding of an image by reasoning about the physical constraints of the scene.

In much the same way that a child might use a set of toy building blocks to… read more

CMU announces research project to reverse-engineer brain algorithms, funded by IARPA

A Human Genome Project-level plan to make computers learn like humans

neural network - CMU ft

Carnegie Mellon University is embarking on a five-year, $12 million research effort to reverse-engineer the brain and “make computers think more like humans,” funded by the U.S. Intelligence Advanced Research Projects Activity (IARPA). The research is led by Tai Sing Lee, a professor in the Computer Science Department and the Center for the Neural Basis of Cognition (CNBC).

The research effort, through IARPA’s… read more
