Spray-n-Sense: Spray-painting sensors on any surface

Researchers have developed a sprayable on-site sensing tool. The main application area for this sensor spray is the detection of specific analytes in an environment where sample collection is a difficult task either due to the target chemicals themselves or the area where the samples are located. A nebulization method allows for nanofibers to be sprayed onto any surface, while the accompanying phone-based application allows for direct on-site detection.

Solving the solar energy storage problem with rechargeable batteries that can convert and store energy at once

Currently, solar is converted to electricity in solar cells, which cannot store the energy long-term, and separate battery storage systems are inconvenient and expensive. To solve this problem, researchers are trying to find ways to combine the power conversion and storage capacity needs of solar energy into one device.

'Hot' graphene reveals migration of carbon atoms

The migration of carbon atoms on the surface of graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron microscope, their effect on the stability of the material can now be determined indirectly while the material is heated on a microscopic hot plate.
