Research aims to improve lithium-based batteries

Research probing the complex science behind the formation of dendrites that cause lithium-ion batteries to fail could bring safer, longer-lasting batteries capable of being charged within minutes instead of hours.

An electron takes 40 attoseconds to pass through a single layer of atoms

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.

New nanotechnology image contest hosted by the NNI

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.

Wearable nanowire sensor clears path to long-term EKG, EMG monitoring

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.

Atoms can be in two places at the same time

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.

A contractile gel that stores light energy

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.
