Generation of super-resolved optical needle and multifocal array using graphene oxide metalenses

Compared to conventional lenses, metalenses can improve the image quality of current cameras, by enhancing resolution and removing spherical and chromatic aberrations.

Research finds a potential new 'silver bullet' nanoparticle to treat brain cancer

The study characterised and evaluated the properties of nanoparticles made from lanthanum manganite, that were doped with silver atoms.

New nanoscale device for spin technology

Spin waves could unlock the next generation of computer technology, a new component allows physicists to control them.

Oxygen migration enables ferroelectricity on nanoscale

Hafnium-based thin films, with a thickness of only a few nanometres, show an unconventional form of ferroelectricity. This allows the construction of nanometre-sized memories or logic devices.

Dye-based device sees the invisible

Devices that can see shortwave infrared light, which is invisible to the naked eye, could soon become cheaper and more accessible to a broader consumer base.

The whitest paint is here - and it's the coolest. Literally.

In an effort to curb global warming, engineers have created the whitest paint yet. Coating buildings with this paint may one day cool them off enough to reduce the need for air conditioning, the researchers say.
