Optical superoscillation without side waves

Optical superoscillation refers to a wave packet that can oscillate locally in a frequency exceeding its highest Fourier component. This intriguing phenomenon enables production of extremely localized waves that can break ...

Tracking topological conditions in graphene

Scientists have been able to demonstrate that graphene nanostructures can be generated by annealing of a nanostructured silicon carbide crystal for a few years. "These two-dimensional, spatially strongly restricted carbon ...

Magnetic nature of complex vortex-like structures

Recently, observation of new topological magnetic structures represented by skyrmions is expected to provide new paths in constructing spintronic devices. In magnetic bubbles, although these are "ancient" cylinder domains, ...

Nanostructures modeled on moth eyes effective for anti-icing

Researchers have been working for decades on improving the anti-icing performance of functional surfaces. Ice accumulation on aircraft wings, for instance, can reduce lifting force, block moving parts and cause disastrous ...

Harvesting hydrogen from nanogardens

Easily produced, nature-like nanostructures of cobalt phosphide are highly effective catalysts for the electrolysis of water, according to research performed by chemist Ning Yan and his team at the University of Amsterdam's ...

Team develops method for trapping elusive electrons

Graphene's unique 2-D structure means that electrons travel through it differently than in most other materials. One consequence of this unique transport is that applying a voltage doesn't stop the electrons like it does ...
