Scalablemanufactured randomized glasspolymer hybrid

Passive radiative cooling requires a material that radiates heat away while allowing solar radiation to pass through. Zhai et al. solve this riddle by constructing a metamaterial composed of a polymer layer embedded with microspheres, backed with a thin layer of silver (see the Perspective by Zhang). The result is an easytomanufacture material near the theoretical limit for daytime radiative

Materials Free FullText Al2O3Cu Substrate with Co

Both Al2O3/glass/Cuf and Al2O3/30glass/Cup composite substrates were hotpressed at 850 °C under 25 MPa. Experimental results showed that the thermal conductivity of Al2O3/30glass/30Cuf composite substrate was as high as 38.9 W/mK, which was about 6 times that of Al2O3/30glass in contrast, the thermal conductivity of Al2O3/30glass/30Cup

Glass Ingredients What is Glass Made Of?

Here are the basic components of modern glass: . Pure Silica (SiO2, fused quartz) represents 7074% weight of modern glass. In ancient times, glassworkers prepared recipes with more than 90% of pure silica, but because this substance has a melting point of about 2000 degrees centigrade (3,600° F) chemist found a way to lower that temperature by introducing various additives into the mix
