Properties of graphene change in humid conditions

Graphene exhibits very different properties in humid conditions, according to researchers.

New material to push the boundaries of silicon-based electronics

Scientists are researching the novel semiconductor material scandium aluminum nitride that may be better suited for future power electronics than silicon.

Broadband achromatic metalens focuses light regardless of polarization

Researchers have developed a polarization-insensitive metalens that can achromatically focus light across the visible spectrum without aberrations. This flat lens could be used for everything from virtual or augmented reality headsets to microscopy, lithography, sensors, and displays.

Can nanotechnology rewire an injured spinal cord?

The ByAxon project is developing a new implant that restores the transmission of electrical signals in an injured central nervous system.

Smart microrobots that can adapt to their surroundings

Scientists have developed tiny elastic robots that can change shape depending on their surroundings. Modeled after bacteria and fully biocompatible, these robots optimize their movements so as to get to hard-to-reach areas of the human body. They stand to revolutionize targeted drug delivery.

Using bacteria to create a graphene oxide based water filter that kills bacteria

Engineers have created a bacteria-filtering membrane using graphene oxide and bacterial nanocellulose. It's highly efficient, long-lasting and environmentally friendly - and could provide clean water for those in need.
