Researchers are modernizing the 'Rebana Ubi', a traditional Malaysian musical instrument by infusing it with a modern computer aided technology.
A breakthrough in the design of signal amplifiers for mobile phone masts could deliver a massive 200MW cut in the load on UK power stations, reducing carbon dioxide emissions by around 0.5 million tonnes a year. Researchers have designed an amplifier that works at 50 percent efficiency compared with the 30 percent now typically achieved.
By combining the powers of two single-atom-thick carbon structures, researchers have created a new ultracapacitor that is both high performance and low cost. The device capitalizes on the synergy brought by mixing graphene flakes with single-walled carbon nanotubes, two carbon nanostructures with complementary properties.
Scientists are in the early stages of an 'e-health technology' project aimed at developing a mobile phone app that can examine blood sample images and diagnose cancer. It would work by taking a magnified image of a blood slide via a microscopic lens attached to the smart phone, which the app would then be able to screen for evidence of leukemia -- a blood cancer.
Researchers have achieved 14-percent efficiency in a 9-millimeter-square solar cell made of gallium arsenide. It is the highest efficiency rating for a solar cell that size and made with that material.
Progress made in developing nanoscale electronics: New research directs charges through single molecules
Scientists are facing a number of barriers as they try to develop circuits that are microscopic in size, including how to reliably control the current that flows through a circuit that is the width of a single molecule. Chemical engineers have now figured out how to reliably control the current that flows through a circuit that is the width of a single molecule.
Agricultural and fruit producers could acquire high-tech greenhouses at a considerably less cost, thanks to researchers who are developing computer systems to control climatic variables within such infrastructures. The technology consists of a motherboard, embedded computer systems (for specific functions), a graphical interface for monitoring variables such as humidity, temperature , wind speed and radiation, as well as elements that enable wireless connectivity between the greenhouse and mobile devices like cell phones.
Ever stop to consider why lotus plant leaves always look clean? The hydrophobic -- water repelling -- characteristic of the leaf, termed the "Lotus effect," helps the plant survive in muddy swamps, repelling dirt and producing beautiful flowers. Of late, engineers have been paying more and more attention to nature's efficiencies, such as the Lotus effect, and studying its behavior in order to make advances in technology. As one example, learning more about swarming schools of fish is aiding in the development of unmanned underwater vehicles. Other researchers are observing the extraordinary navigational abilities of bats that might lead to new ways to reconfigure aviation highways in the skies.
Researchers have shown how to switch a particular transition metal oxide, a lanthanum nickelate, from a metal to an insulator by making the material less than a nanometer thick. Ever-shrinking electronic devices could get down to atomic dimensions with the help of transition metal oxides, a class of materials that seems to have it all: superconductivity, magnetoresistance and other exotic properties. These possibilities have scientists excited to understand everything about these materials, and to find new ways to control their properties at the most fundamental levels.
A great improvement has been demonstrated in the distance that electric power can travel wirelessly. Researchers developed the 'Dipole Coil Resonant System' for an extended range of inductive power transfer, up to 5 meters between transmitter and receiver coils. "Our technology proved the possibility of a new remote power delivery mechanism that has never been tried at such a long distance. Although the long-range wireless power transfer is still in an early stage of commercialization and quite costly to implement, we believe that this is the right direction for electric power to be supplied in the future. Just like we see Wi-Fi zones everywhere today, we will eventually have many Wi-Power zones at such places as restaurants and streets that provide electric power wirelessly to electronic devices," they say.
Information storage for the next generation of plastic computers: Efficient conversion from magnetic storage to light is key
Inexpensive computers, cell phones and other systems that substitute flexible plastic for silicon chips may be one step closer to reality, thanks to new research. Scientists have made a new proposal for overcoming a major obstacle to the development of such plastic devices -- the large amount of energy required to read stored information.
