Coating For Nanotubes Helps Shrink Mass Spectrometers
2014-03-28 11:52:02

By Elizabeth K. Gardner, Purdue University Nanotechnology is advancing tools likened to Star Trek's "tricorder" that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety. Researchers found that when paper used to collect a sample was coated with carbon nanotubes, the voltage required was 1,000 times reduced, the signal was sharpened and the equipment was able to capture far more delicate molecules. A team...

“We are trying to take powerful and sophisticated instruments out of the lab and into the real environment where, for example, they could monitor fresh produce all along the supply chain, from production to the consumers. This technology has the capability of testing for bacteria in only a matter of minutes as opposed to hours or even days for standard laboratory tests.” New York, NY (PRWEB) May 08, 2013 The Camille and Henry Dreyfus Foundation has announced that R. Graham...

New Tool Helps Brain Surgeons Test Brain Tissue During Surgery
2013-01-10 13:25:09

Purdue University A new tool that could allow for faster, more comprehensive testing of brain tissue during surgery successfully identified the cancer type, grade and tumor margins in five brain surgery patients, according to a Purdue University and Brigham and Women's Hospital study. The tool sprays a microscopic stream of charged solvent onto the tissue surface to gather information about its molecular makeup and produces a color-coded image that reveals the nature and concentration...

U.S. scientists say they have developed an analytical tool that can detail the distribution of a drug within the body and without any chemical pretreatment. A team led by Purdue University Professor R. Graham Cooks said knowing where a drug is circulated and where it accumulates in the body is critical to evaluating its effectiveness and potential for toxicity. "This is the first analysis that works on an unadulterated sample to show where a drug and its metabolites travel in the body,"...

WASHINGTON - Scientists have found ways to tease even more clues out of fingerprints' telltale marks - one in a string of developments that gives modern forensics even better ways to solve mysteries like the anthrax attacks or JonBenet Ramsey's murder. For example, if a person handled cocaine, explosives or other materials, there could be enough left in a fingerprint to identify them, says chemist R. Graham Cooks of Purdue University in West Lafayette, Ind. Progress in forensics...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
