As urban residents know, air quality is a big deal. When local pollution levels go up, the associated health risks also increase, especially for children and seniors. But air pollution varies widely over the course of a day and by location, even within the same city. Now scientists, reporting in the ACS journal Environmental Science & Technology, have used smartphone and sensing technology to better pinpoint where and when pollution is at its worst.
Helium leak-detection systems are helping transmission suppliers improve quality and reduce the cost of producing new automatic transmissions developed to improve fuel economy.
Researchers from Chongqing University in China have developed a high sensitive fluorescence-based sensor device that can rapidly identify cancer related volatile organic compounds -- biomarkers found exclusively in the exhaled breath of some people with lung cancer.
The University of Houston received funding from the U.S. Department of Homeland Security (DHS) to conduct research on making biochemical threat detection economically sustainable.
Scientists at the University of South Florida's College of Marine Science have developed a handheld sensor capable of debunking fraudulent seafood species claims, helping to ensure that consumers are get what they pay for.
Researchers can now take advantage of enhancements to ultrapure methylene chloride solvents that deliver an interference-free baseline in chromatograms for better detection of trace levels of target analytes in identifying compounds of interest. This is particularly important for environmental testing of polycyclic aromatic hydrocarbons (PAHs), as well as pesticides in food, water, and soil samples.
One in twelve children are born prematurely in Switzerland. If hypoglycemia develops in these premature babies and persists for over an hour, it can affect brain development. In order to prevent this, the babies' blood sugar levels need to be measured at regular intervals, which, until now, inevitably meant taking blood samples.
Every odour has its own specific pattern which our noses are able to identify. Using a combination of proteins coupled to transistors, for the first time machines are able to differentiate smells that are mirror images of each other, so called chiral molecules, something that has not been possible before.
What if a solider could test for explosive residue on a suspect’s hand in the middle of a warzone with a simple hand-held sensor? Or health care providers could get quick information about a patient’s movement abilities with simple technology in the bottom of a shoe? Or if graphene —a one-atom thick layer of carbon atoms that many experts believe will transform electronic technology in coming decades —could be mass produced?
A technology developed at North Dakota State University, Fargo, creates precise in-the-ground measurement and monitoring of soil and crop conditions which could provide opportunities for greater yields. The technology also has led to a new start-up company. The c2sensor corp., based in the NDSU Technology Incubator, has concluded a license agreement with the NDSU Research Foundation (NDSU/RF) for the precision agriculture technology.
