To improve fuel cell module durability and predict longevity, researchers are studying the degradation mechanisms of the fuel cells that occur under real-world transit bus conditions. While quantifying the effects of electrode degradation stressors in the operating cycle of the bus on the membrane lifetime, the team has discovered links between electrode degradation and membrane durability.
Laser technology has uncovered a network of roadways and canals, illustrating a...
Agilent Technologies Inc. this week announced that the Broad Institute in Cambridge,...
Light-emitting diodes, or LEDs, are the most efficient and environmentally friendly light bulbs...
Researchers at Chalmers Univ. of Technology have found an effective solution for collecting sunlight for artificial photosynthesis. By combining self-assembling DNA molecules with simple dye molecules, the researchers have created a system that resembles nature's own antenna system.
The first commercial application of computational photography is the so-called light-field camera, which can measure not only the intensity of incoming light but also its angle. However these cameras trade a good deal of resolution for that extra angle information. That is, until now.
Japan's nuclear watchdog formally approved a set of new safety requirements for atomic power plants Wednesday, paving the way for the reopening of facilities shut down since the Fukushima disaster. The new requirements approved by the Nuclear Regulation Authority will take effect on July 8, when operators will be able to apply for inspections.
When it's in flight, there's no roar of engines. It's strangely quiet. And as it crisscrosses the U.S., the spindly plane doesn't use a drop of fuel. Ernest Moniz, who heads the U.S. Department of Energy, praised the efficiency of the Solar Impulse plane at a news conference Monday in Washington, where the plane landed early Sunday morning. He said the solar-powered aircraft highlighted a cleaner energy future for the nation.
Nearly 120 scientists and engineers from around the world are meeting in South Dakota this week to discuss operational and technical issues with collecting images from the Landsat 8 satellite. In February, NASA launched the satellite, which takes images of every inch of the Earth’s surface to see what happens over time, and recently handed over operational control of it to the EROS Center.
This week, Sandia National Laboratories is hosting the seventh annual Western National Robot Rodeo and Capability Exercise, a challenging five-day event that draws civilian and military bomb squad teams from across the country to see who can most effectively defuse dangerous situations with the help of robots. The competition provides an opportunity to practice using robots and new technology in a low-risk, but competitive environment.
More than 2,500 attendees turned out for the 2013 RAPID Conference and Exposition, almost doubling last year’s attendance and reflecting widespread excitement about 3D printing and additive manufacturing, according to event organizer SME. It included attendees from nearly 30 countries and the U.S.
State lawmakers on Tuesday approved legislation that would invest millions of dollars in public and private money in Wisconsin startups despite criticism that the investment targets only limited industries. The bipartisan legislation would create a program that invests $25 million from the state and at least $50 million in private money in young Wisconsin companies
Since 1947, Insaco, Quakertown, Pa., has provided precision machining and polishing of fabricated parts from most technical ceramics, sapphire, glass and quartz. The company machines these materials to very precise tolerances—many times measured in millionths of an inch—for dimension, flatness, wedge and roundness or cylindricity.
A single advanced building control now in development could slash 18%—tens of thousands of dollars—off the overall annual energy bill of the average large office building, with no loss of comfort, according to a report by researchers at the Pacific Northwest National Laboratory.
3-D printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have lingered on laboratory benches for lack of a battery small enough to fit the device, yet provide enough stored energy to power them.
The world’s most powerful microscope, which resides in a specially constructed room at the Univ. of Victoria, has now been fully assembled and tested, and has a lineup of scientists and businesses eager to use it. The seven-ton, 4.5-m-tall scanning transmission electron holography microscope, the first such microscope of its type, came to the university in parts last year.
Opioids are still the most effective class of painkillers, but they come with unwanted side effects. Designing new drugs of this type involves testing them on their corresponding receptors, but access to meaningful quantities of these receptors that work in experimental conditions has been a limiting factor. Now, researchers have developed a variant of the mu opioid receptor that has several advantages when it comes to experimentation.
John Hill, a Brookhaven National Laboratory scientist, and his team watched with eager anticipation as controllers ramped up the power systems driving SLAC National Accelerator Laboratory's x-ray laser in an attempt to achieve the record high energies needed to make his experiment a runaway success. To reach the high x-ray energies they were aiming for, all of the 80 klystrons associated with LCLS would need to operate at near-peak levels.
Researchers at the Univ. of New South Wales have proposed a new way to distinguish between quantum bits that are placed only a few nanometers apart in a silicon chip, taking them a step closer to the construction of a large-scale quantum computer.
