Researchers report that magnetite nanoparticles, which are mechanically rotated by external oscillating magnetic fields, could disturb the water/crystal interface and promote supercooling during the freezing process.
Researchers have developed a technique to manipulate the electrical conductivity of graphene with compression, bringing the material one step closer to being a viable semiconductor for use in today's electronic devices.
Scientists have developed small and extremely sensitive gas sensors for acetone, ammonia, and isoprene - all metabolic products that we emit in low concentrations via our breath or skin. They combined these sensors in a device with two commercial sensors for CO2 and moisture.
Researchers have developed a precise microscale manipulation method by rapidly flowing cell suspensions through a specially designed microchannel. This novel microfluidic device enables high-throughput sized-based cell sorting of a large amount of biological samples, which has broad applications in practical biomedical research and pharmaceutical fields.
Researchers have applied a new method to study nanoparticles made of cadmium telluride. They used a peculiar feature of this compound: its interaction with light differs depending on the magnetic field.
Scientists are one step closer to building a carbon-recycling system that can harvest solar energy to efficiently convert CO2 and water into liquid fuels. By optimizing many parts of the system, the researchers say, they can now drive two-electron chemical reactions, a substantial advance over one-electron reactions, which are energy inefficient.
