TetR is one of many proteins in the TetR protein family, which is so named because TetR is the most well characterized member. [2] TetR is used in artificially engineered gene regulatory networks because of its capacity for fine regulation of promoters.
It is less volatile than chloroform, therefore it was more difficult to apply and needed warm water to evaporate. [55] Its smell has been described as "fruity", [55] quince-like [57] and "more pleasant than chloroform", [51] and had a "pleasant taste". [55] Carbon tetrachloride for anaesthetic use was made by the chlorination of carbon disulfide.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
The following table gives the crystalline structure of the most thermodynamically stable form(s) for elements that are solid at standard temperature and pressure. Each element is shaded by a color representing its respective Bravais lattice, except that all orthorhombic lattices are grouped together.
The Romans used it for tablets, water pipes, coins, and even cooking utensils; indeed, as a result of the last use, lead poisoning was recognized in the time of Augustus Caesar. The compound known as white lead was apparently prepared as a decorative pigment at least as early as 200 BCE.

Tetrachloroethylene can be made by passing chloroform vapour through a red-hot tube, the side products include hexachlorobenzene and hexachloroethane, as reported in 1886. [10] Most tetrachloroethylene is produced by high-temperature chlorinolysis of light hydrocarbons.
