Researchers have developed a new method to build large areas of semiconductive material that is just two molecules thick and a total of 4.4 nanometers tall. The films function as thin film transistors, and have potential future applications in flexible electronics or chemical detectors.
A team of chemists has developed an MRI-based technique that can quickly diagnose what ails certain types of batteries--from determining how much charge remains to detecting internal defects--without opening them up.
Researchers have found new methods to measure the internal pressure and surface tension of nano-sized drops of liquid like those involved in cloud formation and airborne pollutants to study how they behave in different environments.
Researchers have explained how the surface characteristics of microspheres affect rapid increases in the viscosity of suspensions, thus laying the groundwork for applications such as smoothly flowing cement.
Researchers used nanoscale spikes of carbon to catalyze a reaction that generates ammonia from nitrogen and water, aided by lithium salt and the application of an electric field. The study reveals a type of catalyst that has been theoretically suggested but never demonstrated.
