A new method enables electroluminescence on large, curved surfaces in a cost-effective way: in this case, the light-emitting layer and all other components are produced by means of wet-chemical, printable methods.
The use of colloidal silver to treat illnesses has become more popular in recent years, but its ingestion, prohibited in countries like the U.S., can be harmful to health. Scientists have now confirmed that silver nanoparticles are significantly toxic when they penetrate cells, although the number of toxic radicals they generate can vary by coating them with carbohydrates.
A major hurdle in structural biology and pharmacology is growing crystals to determine the structure of the biomolecules and pharmaceuticals under study. Researchers have now observed a key step in the nucleation and growth of some protein crystals.
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 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.
