Silicones Essential Chemical Industry

+

Silicones are synthetic polymers with a siliconoxygen backbone similar to that in silicon dioxide (silica), but with organic groups attached to the silicon atoms by CSi bonds. The silicone chain exposes organic groups to the outside. Thus, despite having a very polar chain, the physical properties of silicones are similar to those of an alkane.

Silicon Uptake in Diatoms Revisited: A ... Plant Physiology

+

The silicic acid uptake kinetics of diatoms were studied to provide a mechanistic explanation for previous work demonstrating both nonsaturable and MichaelisMententype saturable uptake. Using 68Ge(OH)4 as a radiotracer for Si(OH)4, we showed a timedependent transition from nonsaturable to saturable uptake kinetics in multiple diatom species. In cells grown under silicon (Si)replete ...

Rice ( Oryza sativa L. cv Oochikara) is a typical siliconaccumulating plant, but the mechanism responsible for the high silicon uptake by the roots is poorly understood. We characterized the silicon uptake system in rice roots by using a lowsilicon rice mutant ( lsi1 ) and wildtype rice. A kinetic study showed that the concentration of silicon in the root symplastic solution increased with ...

The plant was later rebuilt and continues to produce silica aerogels using the TMOS process. The plant is currently operated by the Airglass Corp. In 1983 the Arlon Hunt and the Microstructured Materials Group at Berkeley Lab found that the very toxic compound TMOS could be replaced with tetraethylorthosilicate (TEOS), a much safer reagent.
