Glycolic acid is an ingredient with serious skin benefits, like reducing pigmentation, uneven texture, acne, and wrinkles. Here's how to use it in your routine.

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.

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 ...

New or existing refining plants deserve the best: CTi Nano Neutralization ® can be effortlessly incorporated, in line, at an existing oil refining facility to improve the oil yield and save silica or wash water, reduce the consumption of phosphoric acid and caustic, and can even allow savings on steam, maintenance, repair parts and labor costs.

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 ...

· Crystalline silica is a common mineral found in the earth's crust. Materials like sand, stone, concrete, and mortar contain crystalline silica. It is also used to make products such as glass, pottery, ceramics, bricks, and artificial stone. Respirable crystalline silica – very small particles at ...

Washed sand has a number of very specific applications, including as a mortar mix for bricks and stonework, for manmade beaches or improvement of already existing beaches, for volleyball courts, as well as many of the same uses as silica sand, such as landscaping and pool installation, as a spread on ice or snowcovered roads, concrete and mortar mixing, among other uses.

BASF Corporation is the largest affiliate of BASF SE and the second largest producer and marketer of chemicals and related products in North America.

Triple Green, part 2: Silicon may be made of sand, but it is far from harmless. By the time the quartz becomes a module, it has lost its innocence. Nuclear power is used to smelt it, and the ...

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.

· Author summary Nucleic acid amplification has proven to be indispensable in laboratories around the world for a myriad of applications from diagnostics to genotyping. The first step in any application aiming to amplify DNA or RNA is the extraction of nucleic acids from a complex biological sample; a task traditionally requiring specialised equipment, trained technicians, and multiple liquid ...
