Researchers have developed nanoscale sensors that could be injected into the body to noninvasively track brain activity using light. The approach could one day offer a new way to study the brain or assess patients' brain ...
Optical metasurfaces can unprecedently regulate versatile wavefronts at the subwavelength scale. Most well-established optical metasurfaces are, however, static and feature well-defined optical responses that are determined ...
Researchers report that small quantities of useful molecules such as hydrocarbons are produced when carbon dioxide and water react in the presence of light and a silver nanoparticle catalyst. Their validation study—made ...
Entering an invisible doorway to catch a train at King's Cross station in London is a renowned fictional scene from the Harry Potter series. In recent decades, physicists have been trying to produce a similar effect by focusing ...
Optical cloaking allows objects to be hidden in plain sight or to become invisible by guiding light around anything placed inside the cloak. While cloaking has been popularized in fiction, like in the "Harry Potter" books, ...
Researchers studying how bubbles form and function are sending a fully automated, self-contained experiment into space.
For millennia, silver has been utilized for its antimicrobial and antibacterial properties. Although its use as a disinfectant is widely known, the effects of silver's interaction with bacteria on the silver itself are not ...
Because individual atoms or molecules are 100 to 1000 times smaller than the wavelength of visible light, it is notoriously difficult to collect information about their dynamics, especially when they are embedded within larger ...
A team of researchers at the University of Ottawa has found a way to use visible light to transform carbon dioxide gas, or CO2, into solid carbon forms that emit light. This development creates a new, low-energy CO2 reduction ...
Surface plasmon polaritons (SPPs) are highly localized surface waves on the interface between metal and dielectric in the optical frequency band. SPPs do not naturally exist in the microwave and terahertz frequencies, so ...
