Observations confirmed that dark coating can reduce satellite reflectivity by half. There are concerns that numerous artificial satellites in orbit could impair astronomical observations, but these ...

To fabricate micro/nano structures on metal surfaces, various technologies have been proposed, including chemical etching, mechanical grooving, reactive ion etching, and long-pulse laser processing.

Surface reflectance is a measure of how much of the incident light is reflected by a given surface. For optical applications driven by the absorption of light, minimizing surface reflectance is ...

Engineers have found a way to make liquid metals switch between reflective surfaces or those that scatter light. The transition only requires a small zap of electricity and could be used to make ...

Hot and arid climates benefit most from the combination of agriculture and PV farms. Image: Iberdrola. Combining solar modules and crops in an area is not a new idea in the PV industry since it could ...

Optical Profilometry employs light to measure surface contours and roughness by analyzing the interaction between light waves and the surface under examination. It utilizes various principles such as ...

Observations conducted by the Murikabushi Telescope of Ishigakijima Astronomical Observatory confirmed that dark coating can reduce satellite reflectivity by half. There are concerns that numerous ...
