Bone decalcification is the softening of bones due to the removal of calcium ions, and can be performed as a histological technique to study bones and extract DNA. [1] [2] This process also occurs naturally during bone development and growth, and when uninhibited, can cause diseases such as osteomalacia.
Limescale build-up inside a pipe reduces both liquid flow and thermal conduction from the pipe, so will reduce thermal efficiency when used as a heat exchanger.. A descaling agent or chemical descaler is a liquid chemical substance used to remove limescale from metal surfaces in contact with hot water, such as in boilers, water heaters, and kettles.
e-SDS, otherwise known as an extended SDS.An extended SDS is a document of chemical safety. It is much longer and detailed than the standard SDS. It consists of a standard SDS which has more subsections than the general one, and an additional annex containing one or more exposure scenario(s).
Magnetic water treatment (also known as anti-scale magnetic treatment or AMT) is a disproven method of reducing the effects of hard water by passing it through a magnetic field as a non-chemical alternative to water softening.
Ammonium fluorosilicate (also known as ammonium hexafluorosilicate, ammonium fluosilicate or ammonium silicofluoride) has the formula (NH 4) 2 SiF 6.It is a toxic chemical, like all salts of fluorosilicic acid. [4]
The sodium and potassium salts adopt very similar structures in the solid state, according to X-ray crystallography.In the sodium salt, the O-O distance is 1.476 Å. The sulfate groups are tetrahedral, with three short S-O distances near 1.44 and one long S-O bond at 1.64 Å.
Methylthioninium chloride, commonly called methylene blue, is a salt used as a dye and as a medication. As a medication, it is mainly used to treat methemoglobinemia.It has previously been used for treating cyanide poisoning and urinary tract infections, but this use is no longer recommended.
Deicing a Boeing 737 with Type I fluid A layer of Type IV anti-icing fluid. De-icing fluids come in a variety of types, and are typically composed of ethylene glycol (EG) or propylene glycol (PG), along with other ingredients such as thickening agents, surfactants (wetting agents), corrosion inhibitors, colors, and UV-sensitive dye.
