Researchers have created tiny holograms using a 'metasurface' capable of the ultra-efficient control of light, representing a potential new technology for advanced sensors, high-resolution displays and information processing.
Stanford University scientists have created a silicon-based water splitter that is both low-cost and corrosion-free. The novel device - a silicon semiconductor coated in an ultrathin layer of nickel - could help pave the way for large-scale production of clean hydrogen fuel from sunlight, according to the scientists.
A center to discover what new properties can be created when atom-thick 2-dimensional layers of elemental materials and chemical compounds are formed or when those layers are built up into completely new 3-dimensional structures has opened.
When you squeeze atoms, you don't get atom juice. You get magnets. According to a new theory by Rice University scientists, imperfections in certain two-dimensional materials create the conditions by which nanoscale magnetic fields arise.
A pair of carbon nanotube arrays will be flying in space by the end of the year to test technology that could provide more efficient micro-propulsion for future spacecraft. The arrays will support what is expected to be the first-ever space-based testing of carbon nanotubes as electron emitters.
One atom equals one bit: According to this design principle, we would like to construct magnetic data memories in the future. Researchers now have ixed a single atom on a surface such that the magnetic spin remained stable for ten minutes.
Quite by accident, Washington State University researchers have achieved a 400-fold increase in the electrical conductivity of a crystal simply by exposing it to light. The effect, which lasted for days after the light was turned off, could dramatically improve the performance of devices like computer chips.
