By using an ultrafast camera, scientists say they have observed the very first instants following the absorption of light into artificial yet organic nanostructures and found that charges not only formed rapidly but also separated very quickly over long distances - phenomena that occur due to the wavelike nature of electrons which are governed by fundamental laws of quantum mechanics.
A new type of transistor that could make possible fast and low-power computing devices for energy-constrained applications such as smart sensor networks, implantable medical electronics and ultra-mobile computing is feasible. Called a near broken-gap tunnel field effect transistor, the new device uses the quantum mechanical tunneling of electrons through an ultrathin energy barrier to provide high current at low voltage.
Networks of nanometer-scale machines offer exciting potential applications in medicine, industry, environmental protection and defense, but until now there's been one very small problem: the limited capability of nanoscale antennas fabricated from traditional metallic components.
Nanotechnology researchers have discovered an efficient and easy-to-use method for bonding together gels and biological tissues. They succeeded in obtaining very strong adhesion between two gels by spreading on their surface a solution containing nanoparticles.
The European Commission presented for the first time today calls for Proposals under Horizon 2020, the European Union's new 80 billion euro research and innovation program, which runs from 2014 to 2020.
A new, low-cost cubesat mission led by the Johns Hopkins Applied Physics Laboratory will demonstrate technology needed to measure the absolute imbalance in the Earth's radiation budget for the first time, giving scientists valuable information to study our climate.
There are examples of art imitating nature all around us - the human conception of natural phenomena dazzles but does not often surprise. Yet when a researcher peered under the electron microscope last fall, she discovered the exact opposite. Instead of art imitating nature, she found nature imitating art.
A new study evaluates the impact of polyvinylpyrrolidone coated silver nanoparticles on the composting of municipal solid waste. The findings suggest that at relatively low concentrations, the organically rich waste management systems' functionality may not be influenced by the presence of silver nanoparticles.
