Silk could improve sensitivity, flexibility of wearable body sensors

Sun, 20 Aug 2017 00:00:00 EDT

(American Chemical Society) From smart socks to workout clothes that measure exertion, wearable body sensors are becoming the latest 'must-have' technology. Now scientists report they are on the cusp of using silk, one of the world's most coveted fabrics, to develop a more sensitive and flexible generation of these multi-purpose devices that monitor a slew of body functions. The researchers are presenting their results at the 254th National Meeting & Exposition of the American Chemical Society.



Energized fabrics could keep soldiers warm and battle-ready in frigid climates

Sun, 20 Aug 2017 00:00:00 EDT

(American Chemical Society) Soldiering in arctic conditions is tough. Protective clothing can be heavy and can cause overheating and sweating, while hands and feet can grow numb. To keep military personnel more comfortable, scientists are trying to create high-tech fabrics that heat up when powered and that capture sweat. These fabrics could conceivably be used in future consumer clothing. The researchers will present their results today at the 254th National Meeting & Exposition of the American Chemical Society.

Gold shines through properties of nano biosensors

Wed, 16 Aug 2017 00:00:00 EDT

(American Institute of Physics) With their remarkable electrical and optical properties, along with biocompatibility, photostability and chemical stability, gold nanoclusters are gaining a foothold in a number of research areas, particularly in biosensing and biolabeling. An international research team has now shown that the fluorescence is an intrinsic property of the gold nanoparticles themselves. The researchers used Au20, gold nanoparticles with a tetrahedral structure. Their findings were reported this week in The Journal of Chemical Physics.



Multicolor MRIs could aid disease detection

Wed, 16 Aug 2017 00:00:00 EDT

(Case Western Reserve University) Researchers at Case Western Reserve University School of Medicine have developed a method that could make magnetic resonance imaging -- MRI -- multicolor. Current MRI techniques rely on a single contrast agent injected into a patient's veins to vivify images. The new method uses two at once, which could allow doctors to map multiple characteristics of a patient's internal organs in a single MRI. The strategy could serve as a research tool and even aid disease diagnosis.



Candy cane supercapacitor could enable fast charging of mobile phones

Wed, 16 Aug 2017 00:00:00 EDT

(Queen Mary University of London) Supercapacitors promise recharging of phones and other devices in seconds and minutes as opposed to hours for batteries. But current technologies are not usually flexible, have insufficient capacities, and for many their performance quickly degrades with charging cycles. Researchers at Queen Mary University of London and the University of Cambridge have found a way to improve all three problems in one stroke.
