The radar is one of the most important tools that meteorologists use to track and help forecast the weather.

Dielectric mirrors, also referred to as Bragg mirrors, reflect light nearly completely. Hence, they are suited for various applications, such as camera systems and sensor systems for microscopy and ...

Figure 1: Calculated peak reflectivity, interaction length and reflection energy bandwidth for X-rays in Bragg backscattering from diamond for all allowed reflections with Bragg energies E H up to 30 ...

Scientists in Hong Kong have demonstrated a new ultra-white ceramic material that can drastically cool buildings by reflecting sunlight and heat at record highs. The beetle-inspired material gets its ...

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.

Earth is literally losing some of its shine. New readings from NASA’s long‑running satellite missions show that the planet is reflecting slightly less sunlight back into space, a subtle shift that ...

When we think about global warming, we often picture towering smokestacks, congested highways and gases that trap heat in the atmosphere. Our attention is usually fixed on the blanket of carbon ...

Scientific researchers draw inspiration from nature's brilliance as they seek to develop transformative solutions to unresolved challenges. Scientific researchers draw inspiration from nature's ...

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 ...

A new analysis of the Northern Hemisphere’s “albedo feedback” over a 30-year period concludes that the region’s loss of reflectivity due to snow and sea ice decline is more than double what ...
