Analysis of the electrical properties of nanostructures is crucial for the successful development of practical materials that take advantage of atomic-scale properties. Examination at this size regime can be accomplished with a variety of instrumentation, but few tools are as flexible and potent as nanoprobe systems.
During spring break the last five years, a Univ. of Washington class has headed to the Nevada desert to launch rockets and learn more about the science and engineering involved. Sometimes, the launch would fail and a rocket smacked hard into the ground. This year, the session included launches from a balloon that were deliberately directed into a dry lakebed.
Accurate and rapid testing for drug toxicity just became easier, thanks to a half-dozen Rice Univ. student interns working at Houston-based startup Nano3D Biosciences (n3D). The bioengineering and nanoscale physics students just wrapped up a year-long effort to aid the company in developing a new method for conducting high-throughput, in vitro cytotoxicity assays.
Walking is tricky business. And while most artificial feet and limbs do a pretty good job restoring mobility to people who have lost a leg, they have a ways to go before they equal the intricacy of a natural gait. As a result, over half of all amputees take a fall every year, compared to about one-third of people over 65. Researchers are taking a giant step toward solving the problem.
It was a result so unexpected that Massachusetts Institute of Technology researchers initially thought it must be a mistake: Under certain conditions, putting a cracked piece of metal under tension has the reverse effect, causing the crack to close and its edges to fuse together. The surprising finding could lead to self-healing materials that repair incipient damage before it has a chance to spread.
FluxMerge, adjusts the magnetic reluctance distribution across the pole faces opposite the airgap. The magnetic flux crossing over the airgap, as a result, merges toward the central axis along the magnetic circuit path to reduce leakage into the surrounding space. Reduced airgap leakage improves efficiency by about 1.5%, and offers the opportunity for more compact designs.
Product development firm Cambridge Consultants is helping conservationists protect some of the world’s most rare and endangered species. As part of the Instant Wild project, new satellite-connected and motion-triggered cameras are beaming near-real-time images of animals from the remotest areas of Africa. A mobile app allows users anywhere in the world to view the photos, providing early warning of illegal poaching activity.
On Thursday, Virgin Galactic demonstrated the SpaceShipTwo’s full technical mission profile in a single flight for the first time. The second rocket-powered, supersonic flight of its passenger carrying reusable space vehicle marked the first high altitude deployment of the unique wing “feathering” re-entry mechanism and achieved the highest altitude and greatest speed to date.
Ion chromatography (IC) is an analytical technique for the separation and determination of anionic and cationic analytes in various sample matrices. By introducing a high-pressure reagent-free IC system that successfully integrates conductive, electrochemical and charge detection, Thermo Fisher Scientific Inc. has brought a new level of performance and speed to this important separations process.
Curiosity Rover team members re-live the dramatic Aug. 6, 2012 landing and the mission's achievements to date in a recent event aired on NASA Television and the agency's website. In the year since inspiring millions of people worldwide with its one-of-a-kind landing in a crater on the Red Planet, Curiosity has achieved its primary scientific objective; finding evidence that ancient Mars could have sustained microbial life.
Battelle researchers at Pacific Northwest National Laboratory believe one solution to keeping the greenhouse gas, carbon dioxide, out of our atmosphere can be found under our feet. In a first-of-its-kind study, researchers are collecting data on 1,000 tons of CO2 pumped one-half mile underground into basalt in Wallula, Wash. The results will determine if the greenhouse gas can be safely and permanently stored in basalt.
For decades, teams of Berkeley Lab scientists have investigated the ways that indoor air quality affects human health. In Berkeley Lab's test kitchen scientist Brett Singer and his team are measuring the pollutants emitted by cooking foods and evaluating how effective various range hoods are in capturing the pollutants.
In this video, Tim Samaras from the National Geographic Channel Storm Chasers talks about his passion for chasing and studying storm systems. He explains how he used National Instruments’ (NI) LabVIEW and CompactDAQ in a new instrument that is deployed on the ground in front of a tornado. After the storm he uses another NI application, DIAdem, to view the data that was collected.
Laboratory water purification specialists for more than 75 years, ELGA provides complete water purification solutions for new and refurbished laboratories. ELGA has recently released a new set of videos that describe both the company’s expertise in delivering labwater solutions, and the many options for configuring these solutions for the laboratory.
Electron beam freeform fabrication (EBF3) is a layer-additive process that uses an electron beam and wire to fabricate metallic structures. The process efficiencies of the electron beam and the solid wire feedstock make the EBF3 process attractive for use in-space.
