Feathers from the underground ocean

图片
The earth is probably the only planet in the solar system that shows moisture. But astronomers believe that quite a lot of planets contain the entire ocean under the surface, which remains liquid due to the heat generated by gravity and radioactive decay. Potential candidates include Jupiter's largest moon Ganymede; Ceres, the largest object in the asteroid belt; and even Pluto, at the far end of the solar system. However, there are only two cases. Astronomers have direct evidence that these hidden oceans exist in the form of water column coming out of the surface, and only one of these cases is conclusive. In 2013, the Harbert Space Telescope discovered the plumes of Jupiter's icy Jupiter, Europa, but never appeared since then. By contrast, Saturn's icy two - guard two appears to have produced more normal plumes, one of which was Cassini's actual flying spacecraft in 2015. Cassini used his airborne mass spectrometer to confirm that plumes are water and contain simp

Aerogel As Thermal Insulation Material

图片
The microstructure of silica aerogel is effective in limiting the propagation of local heat excitation, and its solid-state thermal conductivity is 2-3 orders of magnitude lower than that of the corresponding glass state materials. Nano-pores inhibit the contribution of gas molecules to heat conduction. The refractive index of silica aerogel is close to L, and the ratio of annihilation coefficient of IR and visible light is more than 100, which can effectively penetrate sunlight and prevent ambient temperature from infrared thermal radiation, and become an ideal transparent insulating material, which has been applied in solar energy utilization and building energy conservation. By means of doping, the radiant heat conduction of silica aerogel can be reduced, and the thermal conductivity of carbon  aerogel  under normal temperature and pressure can be up to 0. 013w/m K, is the lowest thermal conductivity of solid materials, is expected to replace polyurethane foam as a new type of refr

What’s the Difference? Drywall vs. Plaster

图片
If you’re thinking of taking on a wall construction project in your home, you’ll likely hear of two options: drywall and plaster. Newer homes tend to feature drywall, a material comprised of gypsum sandwiched between two sheets of paper and usually sold in 4-foot-by-8-foot panels. Drywall installs quickly and fairly easily by screwing it into the studs of the wall, and today it comes in a variety of thicknesses and other options to choose from. Plaster and lath, on the other hand, is a more labor-intensive but high-end wall treatment where workers nail lengths of wood called lath to the studs and then apply several coats of plaster over top, used in most homes built before World War II. Both methods have their respective strengths and weaknesses, so we’re breaking down the two  oil pipeline insulation   materials here—drywall vs plaster. Keep reading for what you should consider before planning your next project. Plaster is more labor-intensive than drywall. In fact, the shortage
