Holding the Road with Calcium Chloride Flake

Almost no two geographical areas have exactly the same composition of material in their road surfaces. However, with proper gradation, calcium chloride can be used on almost all unpaved surfaces (both large and small), including earth, cinders, gravel, sand, bluestone, shale, limestone, clay, graded crushed stone, shell, and other similar local materials.

The Cosmic Dust in Your Bones

2020/11/18The mid-infrared light that Webb can detect is exactly the wavelength of light we want to look at to study the dust and its chemical composition, Lau explains. Infrared wavelengths are longer than the wavelengths of visible light, and so can slide between dust grains to reach the telescope, rather than getting caught up bouncing around in the dust cloud.
