NIST scientists have designed a vacuum gauge, based on ultracold trapped atoms, is small enough to deploy in commonly used vacuum chambers.
Girls who play video games are three times more likely to choose physical science, technology, engineering or maths (PSTEM) degrees compared to their non-gaming counterparts, according to new research from the University of Surrey.
Collapsible dog bowls and bendable straws seem to work on a common principle, snapping into stable and useful states, but mechanisms have remained elusive. Now a team led by polymer scientists at UMass Amherst discuss how 'pre-stress' built into the structure helps them function.
A study led by Chalmers University of Technology, Sweden, has shown that carbon fibers can work as battery electrodes, storing energy directly. This opens up new opportunities for structural batteries, where the carbon fiber becomes part of the energy system. The use of this type of multifunctional material can contribute to a significant weight-reduction in the aircraft and vehicles of the future -- a key challenge for electrification.
A study of dandelion seeds in motion has revealed a form of flight not seen before, and explains why the plant is among nature's best fliers.
For decades researchers have studied materials from structures to see why and how they fail. Before catastrophic failure, there are individual cracks or dislocations that form, which are signals that a structure may be weakening. While researchers have studied individual dislocations in the past, a team from the University of Illinois at Urbana-Champaign, the University of Tennessee, and Oak Ridge National Laboratory has made it possible to understand how dislocations organize and react at nanoscale.
A battery-free energy harvester, a novel conductive system for smartwatches, and a prototype that extends body language to the human ear feature at new tech conference.
Engineers at MIT have developed an algorithm that quickly pinpoints the types of extreme events that are likely to occur in a complex system, such as an ocean environment, where waves of varying magnitudes, lengths, and heights can create stress and pressure on a ship or offshore platform. The researchers can simulate the forces and stresses that extreme events -- in the form of waves -- may generate on a particular structure.
Graphene Flagship industrial and academic partners published a new paper in Nature Reviews Materials analysing the possibilities of graphene in the internet of everything market, expected to reach over 12 billion connected devices in 2020
On the runway to more fuel-efficient aircraft, one alternative propulsion scheme being explored is an array of electrically powered ducted fans. The fans are distributed across the wing span or integrated into the wing. Researchers at the University of Illinois gained new understanding in how the fans and especially their precise placement on the aircraft can affect the cross-conversation between propulsion and the airflow around the wing.
