Misch metal is generally prepared by the electrolysis of the mixed RCl3.
Galactose is generally prepared by acid hydrolysis (breakdown involving water) of lactose, which is composed of galactose and glucose.
It is generally prepared by acidification of a solution of a silicate, such as water glass; the resulting silicic acid forms either a rigid mass or a gelatinous precipitate from which soluble materials are removed by washing with water.
In that model, food is generally prepared off-site, meaning more chemicals and industrial suppliers are used.
Salted shrimp paste is generally prepared from the planktonous shrimp or krill (Acetes vulgaris or Mesopodopsis orientalis).
Though it is generally prepared with expensive exposure tools like electron-beam lithography, the mould can be reused a very large number of times [31].
Polymorphous silicon film is generally prepared by operating a strong hydrogen-diluted silane plasma source at high pressure and power density [11].
This kind of PAA films is generally prepared in diluted sulfuric acid, and the film growth is very slow due to the low anodizing potential and current density.
Supported NiMo catalyst modified with P has been developed for hydrotreatment of diesel for decades, which is generally prepared using incipient wetness method [10, 11, 12, 13, 14], the addition of the PO4 weakens the interaction of MoS2 with the alumina support, this giving a high activity, while the nickel helped the direct hydrogenation of the sulfur.
Biodiesel which is a blend of a mono alkyl ester of long-chain fatty acids is generally prepared by transesterification of various renewable sources, such as vegetable oil and waste cooking oil that have triglyceride in their composition [4, 5, 6, 7].
