A new class of magnets that expand their volume when placed in a magnetic field and generate negligible amounts of wasteful heat during energy harvesting, has been discovered by researchers at Temple Univ. and the Univ. of Maryland. This transformative breakthrough has the potential to not only displace existing technologies but create altogether new applications due to the unusual combination of magnetic properties.
Radio systems, such as mobile phones and wireless Internet connections, have become an integral part of modern life. However, today's devices use twice as much of the radio spectrum as is necessary. New technology is being developed that could fundamentally change radio design and could increase data rates and network capacity, reduce power consumption, create cheaper devices and enable global roaming.
Computer simulations have predicted a new phase of matter: atomically thin 2-D liquid. This prediction pushes the boundaries of possible phases of materials further than ever before. Two-dimensional materials themselves were considered impossible until the discovery of graphene around 10 years ago.
For decades, the fundamental design of microwave devices, such as antennas for mobile communication and waveguides used in radars, has essentially relied on the inventiveness of a professional designer. Computer simulations are usually used only in final design stages to fine-tune details in the design.
The number of new Ebola cases is tapering off, but the search for new treatments continues. Now, one research team has found potential drug candidates that successfully treated up to 90% of mice exposed to the Ebola virus. They report their findings in ACS Infectious Diseases.
In the story of the Marvel Universe superhero known as the Hulk, exposure to gamma radiation transforms scientist Bruce Banner into a far more powerful version of himself. In a study at Lawrence Berkeley National Laboratory, exposure to alpha-particle radiation has been shown to transform certain thermoelectric materials into far more powerful versions of themselves.
Americans' energy use continued to grow slowly in 2014, fueled by increases in the use of natural gas, wind and solar, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory (LLNL). Each year, the LLNL releases charts that illustrate the nation's consumption and use of energy. Overall, Americans used 0.9 quads BTUs more in 2014 than the previous year, an increase of about 1%.
Type Ia supernovae, one of the most dazzling phenomena in the universe, are produced when small dense stars called white dwarfs explode with ferocious intensity. At their peak, these supernovae can outshine an entire galaxy. Although thousands of supernovae of this kind were found in the last decades, the process by which a white dwarf becomes one has been unclear.
Graphene is a material with a host of potential applications, including in flexible light sources, solar panels that could be integrated into windows and membranes to desalinate and purify water. But all these possible uses face the same big hurdle: the need for a scalable and cost-effective method for continuous manufacturing of graphene films.
Students from four schools took part in a day of physics and football at Arsenal’s Emirates Stadium on May 15, 2015, as the finale of an eight-week program to engage students with science by applying it to soccer. The schools have been running after-school physics and football clubs in which students learnt about such concepts as projectiles, impact area and center of mass and applied their knowledge in practice on the football pitch.
Conventional electroluminescent (EL) foils can be bent up to a certain degree only and can be applied easily onto flat surfaces. The new process allows for the direct printing of electroluminescent layers onto three-dimensional components. Such EL components might be used to enhance safety in buildings in case of power failures. Other potential applications are displays and watches or the creative design of rooms.
A team of researchers has unveiled a new method of controlling the shapes of structures—so called mesoatoms—formed by microdroplets placed inside another drop. The work increases the possibilities of controlling the processes of self-organization of matter. During their research, the scientists also managed for the first time to observe the formation of microdroplet structures with unexpected shapes.
Scientists have discovered a phenomenon that helps them to improve fusion plasmas, a finding that may quicken the development of fusion energy. They found that when they injected tiny grains of lithium into a plasma undergoing a particular kind of turbulence then, under the right conditions, the temperature and pressure rose dramatically. High heat and pressure are crucial to fusion...
A wearable device will provide real-time data analysis of fluid loss during exercise to enhance the performance of fitness enthusiasts and elite athletes. The innovative transdermal sensor is a small device that attaches to the body to analyze electrolytes in sweat, with Bluetooth technology used to send the data back to a smartphone—allowing the user to rehydrate properly and maintain optimum performance
Sandia National Laboratories researchers have made the first measurements of thermoelectric behavior by a nanoporous metal-organic framework (MOF), a development that could lead to an entirely new class of materials for such applications as cooling computer chips and cameras and energy harvesting. This work builds on previous research in which the Sandia team realized electrical conductivity in MOFs by infiltrating the pores with TCNQ.
