A team of physicists has built a microscope that is able to see up to 1,000 individual fermionic atoms. The researchers devised a laser-based technique to trap and freeze fermions in place, and image the particles simultaneously.
Inspired by the way iridescent bird feathers play with light, scientists have created thin films of material in a wide range of pure colors - from red to green - with hues determined by physical structure rather than pigments.
Nanomaterials commonly used in sunscreens and boat-bottom paints are making sea urchin embryos more vulnerable to toxins, according to a new study. The authors said this could pose a risk to coastal, marine and freshwater environments.
Researchers used a copper oxide nanowire decorated with palladium nanoparticles to detect carbon monoxide, a common industrial pollutant. The sensor was tested in conditions similar to ambient air since future devices developed from this method will need to operate in these conditions.
Researchers have developed a new composite photocathode for generating hydrogen using sunlight. The photocathode consists of a thin film of chalcopyrite coated with a newly developed thin film of titanium dioxide containing platinum nanoparticles.
For the first time, a researcher has theoretically demonstrated that it is possible to detect a single nuclear spin at room temperature, which could pave the way for new approaches to medical diagnostics.
They are 'strange' materials, insulators on the inside and conductors on the surface. They also have properties that make them excellent candidates for the development of spintronics and more in general quantum computing. However, they are also elusive as their properties are extremely difficult to observe. Now a study proposes a new family of materials whose topological state can be directly observed experimentally, thus simplifying things for researchers.
The 2015 IEDM is seeking increased participation in the areas of 'Beyond CMOS' devices, flexible devices, neuromorphic computing, power devices, sensors for the Internet of Things (IoT) and variation/reliability.
Currently, organic materials used in these devices offer greater versatility and efficiency at a lower cost than the available inorganic ones, but they show stability problems when in contact with an aqueous medium. Researchers have now achieved an exceptional stability in these devices, which represents an important step in obtaining solar fuels from organic materials.
An international research group has developed a technique for creating nanoscale whispering galleries for electrons in graphene. The development opens the way to building devices that focus and amplify electrons just as lenses focus light and resonators (like the body of a guitar) amplify sound.
