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 ...

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.

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 ...

Earth’s climate is being changed substantially by a buildup of atmospheric greenhouse gases, but a group of leading climate scientists contends the overall impact is not understood as well as it ...

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 ...

That change in reflectivity, known as albedo, is not a distant abstraction. It is emerging in the same decades that have already delivered record heat, stronger heat waves and disrupted seasons, and ...

After Monday’s winter weather, areas around the Peninsulas and the western Southside accumulated three or more inches of snow. And that snow slightly affected high temperatures this week. Snow has a ...

The view of Earth from space is famously familiar—bright blue ocean, swirling gyres of white clouds, touches of terrestrial green. The luminosity of this image is the result of the sun’s rays shining ...
