Graphene quantum dots created at Rice Univ. grab onto graphene platelets like barnacles attach themselves to the hull of a boat. But these dots enhance the properties of the mothership, making them better than platinum catalysts for certain reactions within fuel cells.

Despite being outlawed in 2012 in the U.S., the synthetic drugs known as "bath salts" are still readily available in some retail shops, on the Internet and on the streets. To help law enforcement, scientists are developing low-cost, disposable, mercury-free electrodes that could be the basis for the first portable, on-site testing device for identifying the drugs.
Princeton Instruments has announced the immediate availability of the ProEM-HS line of high-speed EMCCD cameras with patented eXcelon3 technology (X3) for low-light imaging and spectroscopy applications. This advanced back-illuminated EMCCD technology offers combination of high quantum efficiency (>95% QE), best fringe suppression in the near infrared and single-photon sensitivity.
GP:50 Corporation Ltd. has introduced its Model 188/288/388 miniature flush diaphragm pressure transducer series. The unique flush diaphragm design of the GP:50 Model 188/288/388 now makes possible accurate pressure measurements of high-viscosity fluids, even within high shock and vibration environments, without port plugging and clogging.
It was, retired Japanese railway engineer Fumihiro Araki recalls, "like flying in the sky." Zipping cross-country in a super-high-speed train has become commonplace in many countries these days, but it was unheard of when Japan launched its bullet train between Tokyo and Osaka 50 years ago Wednesday.
Inspired by a desire to help wounded soldiers, an international team has created a paint-on, see-through, “smart” bandage that glows to indicate a wound’s tissue oxygenation concentration. Because oxygen plays a critical role in healing, mapping these levels in severe wounds and burns can help to greatly improve the success of surgeries to restore limbs and physical functions.
Brine shrimp, which are sold as pets known as sea-monkeys, are tiny—only about half an inch long each. With about 10 small leaf-like fins that flap about, they look as if they could hardly make waves. But get billions of similarly tiny organisms together and they can move oceans.
Researchers in the Netherlands can now, for the first time, remotely control a miniature light source at timescales of 200 trillionths of a second. Physicists have developed a way of remotely controlling the nanoscale light sources at an extremely short timescale. These light sources are needed to be able to transmit quantum information.
Only a minority of suspicious mammograms actually leads to a cancer diagnosis, which results in lots of needless worry and spent time for women and their families. Ultrasound elastography could be an excellent screening tool but it requires a lot of skill and interpretation. In an effort to improve results, researchers in Michigan have developed a virtual “breast”, allowing medical professionals to practice in the laboratory.
The 52nd annual R&D 100 Awards event will present a series of panel discussions featuring today’s top technological minds revealing their secrets for innovation. Draw inspiration from these leading experts as they discuss technology-driven strategies for transforming your ideas into excellence.
The discovery of a gene mutation that causes a rare premature aging disease could lead to the development of drugs that block the rapid, unstoppable cell division that makes cancer so deadly. Scientists at the Univ. of Michigan recently discovered a protein mutation that causes the devastating disease dyskeratosis congenita, in which precious hematopoietic stem cells can't regenerate and make new blood.
Given a choice, most patients would prefer to take a drug orally instead of getting an injection. Unfortunately, many drugs, can’t be given as a pill because they get broken down in the stomach before they can be absorbed. To help overcome that obstacle, researchers have devised a novel drug capsule coated with tiny needles that can inject drugs directly into the lining of the stomach after swallowed.
Federal health officials on Tuesday confirmed the first case of Ebola diagnosed in the U.S., a patient who recently traveled from Liberia to Dallas and a sign of the far-reaching impact of the out-of-control epidemic in West Africa. The unidentified patient was critically ill and has been in isolation at Texas Health Presbyterian Hospital since Sunday, officials said.
Schaefer Inc. has unveiled new turnkey inverter systems using its Series IT of single or three-phase switch mode inverter systems with a power range from 6 kVA to 90 kVA. These highly reliable, fully-customizable "built-to-project" dc/ac pure sine wave inverters are fully isolated, using a switch mode inverter with a rectifier at input and a transformer at the output.
At Powtech 2014, Malvern Instruments launched Hydro Sight, an imaging accessory for the Mastersizer 3000 particle size analyzer, that allows quicker and easier development and application of robust particle sizing methods. In addition, Malvern launched the Hydro SV, a new wet dispersion unit for the Mastersizer 3000.
Electrical engineers in Germany have demonstrated a new kind of building block for digital integrated circuits. Their experiments show that future computer chips could be based on 3-D arrangements of nanometer-scale magnets instead of transistors. In a 3-D stack of nanomagnets, the researchers have implemented a so-called “majority” logic gate, which could serve as a programmable switch in a digital circuit.
