Researchers at the U.S. Naval Research Laboratory have developed a new technique that could enable future advancements in quantum technology. The technique squeezes quantum dots, tiny particles made of thousands of atoms, to emit single photons (individual particles of light) with precisely the same color and with positions that can be less than a millionth of a meter apart.

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences have developed a highly compact, portable camera that can image polarization in a single shot. The miniature camera — about the size of a thumb — could find a place in the vision systems of autonomous vehicles, onboard planes or satellites to study atmospheric chemistry, or be used to detect camouflaged objects.

Scientists from the Center for Functional Nanomaterials – a U.S. Department of Energy (DOE) Office of Science User Facility at Brookhaven National Laboratory – have come up with a technique for optimizing the activity of zinc oxide nanowires. Their technique involves chemically treating the surface of the nanowires in such a way that they can be uniformly coated with an ultrathin film of titanium dioxide, which acts as both a catalyst and protective layer.

Researchers at Pacific Northwest National Laboratory found that highly porous materials can absorb key components of a class of toxic chemicals found in 43 U.S. states. These nano-sized porous materials, called metal-organic frameworks, can quickly take up fluorinated compounds that were widely used in firefighting foam and non-stick cookware.a

By energizing precursor molecules using a tiny, high-energy supersonic jet of inert gas, researchers have dramatically accelerated the fabrication of nanostructures. The technique allows nanostructures to be made at rates approaching what would be expected in the liquid phase, which could make these nanostructures practical for use in magnetic memory, high-frequency antennas, and quantum communication devices.
