Whereas silicone greases are thickened with a lithium soap, silicone pastes are made by dispersing silica in PDMS (Polydimethylsiloxane) oils with the use of thickening agents. Different amounts of silica are added to the compound to increase its viscosity to the required level. The chemical ...
“Glass is mainly made of silica, which is a natural substance," says Franzisk a Trautmann, the co-founder of Glass Half Full, a New Orleans-based company that recycles glass into sand that can be used for coastal restoration and disaster relief.Silica, also known as silic a dioxide, ...
Another compound found as a mineral and as a clay is magnesium aluminum silicate, which is composed of magnesium, aluminum, silica, and oxygen. In its mineral form, it is a type of garnet called pyrope, which is often used as a gemstone, and it is the only garnet to always be red ...
(Fig.1h, i). The single S431A mutation in the tail domain glycosite also reduced NF-L O-GlcNAcylation, whereas a compound mutant lacking the four head and one tail domain sites (NF-L5A) exhibited total O-GlcNAcylation similar to the NF-L4Amutant (Fig.1h, j), suggesting potential ...
