An international team of researchers has measured how fast an electron races through the atomic layers of a crystal lattice. The physicists used an extremely short laser pulse to time the speed: According to their measurements, the electron needs 40 attoseconds to pass through one layer of magnesium atoms.
The goal is to envision where your research is headed and explain how 'seeing' at the nanoscale is important to reaching that vision. This contest is for students conducting nanotechnology research in the United States and U.S. territories.
Researchers have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiography (EKG) or electromyography (EMG). The new sensor is as accurate as the 'wet electrode' sensors used in hospitals, but can be used for long-term monitoring and is more accurate than existing sensors when a patient is moving.
According to the predictions of quantum mechanics, microscopic objects can take different paths at the same time. The world of macroscopic objects follows other rules: objects always moves in a definite direction. But is this always correct? Physicists have constructed an experiment designed to possibly falsify this thesis. Their first experiment shows that Caesium atoms can indeed take two paths at the same time.
Scientists have made a polymer gel that is able to contract through the action of artificial molecular motors. When activated by light, these nanoscale motors twist the polymer chains in the gel, which as a result contracts by several centimeters.
The new technique is a non-invasive procedure to detect the severity of an allergic reaction to amoxicillin. The developed biosensor platform is based on gold nanodisks, is very sensitive and works label-free, detecting the changes in the refraction index occurring at its surface after the binding of IgEs specific for amoxicillin.
A new semiconductor laser developed at Yale has the potential to significantly improve the imaging quality of the next generation of high-tech microscopes, laser projectors, photolithography, holography, and biomedical imaging.
The Phantoms Foundation and ICEX Spain Trade and Investment, in cooperation with the Embassy of Spain (Economic and Commercial Office) in Tokyo bring together, for the eighth time, a nanoscience and nanotechnology Pavilion at nano tech 2015 (Spanish Pavilion - East Hall 6/Booth 6P-23).
