Scientists have engineered a new way to kill bacteria, and subsequently visualised in real time how the bacteria under attack were stripped of their protective membranes and died. These findings could provide a physical basis for designing more-effective antibiotics.
The amount of light, passing through an opaque layer, can be enhanced using smart techniques. At the same time, the amount of reflected light diminishes, researchers now show. It's as if light speckles have a conversation of their own.
Researchers have proposed various designs of materials of a photonic crystal type that can be used to filter radiation. Specifically, the focus has been to develop a coating comprising dielectric spheres which if applied to a window, for example, would prevent the outside heat entering in the summer and the indoor heat from escaping in winter.
Researchers are exhibiting a new type of antireflective coating that significantly reduces stray light and reflections from plastic lenses. Not only does this improve the performance of cameras and headlights, it's also good news for virtual reality technologies and Industrie 4.0.
Researchers have found an unexpected way to control the thermal conductivity of two-dimensional materials, which will allow electronics designers to dissipate heat in electronic devices that use these materials.
