Lonza Group AG is a Swiss multinational manufacturing company for the pharmaceutical, biotechnology and nutrition sectors, headquartered in Basel, with major facilities in Europe, North America and South Asia. Lonza was established under that name in the late 19th-century in Switzerland.
Cyanate ester. Cyanate esters are chemical compounds in which the hydrogen atom of the cyanic acid is replaced by an organyl group (for example aryl group). The resulting compound is termed a cyanate ester, with the formula R−O−C≡N, where R is an organyl group. Cyanate esters contain a monovalent cyanate group −O−C≡N.
Expandable graphite. Expandable graphite is produced from the naturally occurring mineral graphite. [1] The layered structure of graphite allows some molecules to be intercalated in between the graphite layers. Through incorporation of acids, usually sulfuric acid graphite can be converted into expandable graphite. [2]
Lonza said on Tuesday it has capacity to fill syringes to serve makers of highly popular new weight-loss drugs in a class known as GLP-1, though it does not produce the active ingredient in those ...
2 could be used as a "back gate" electrode to vary the charge density in the graphene over a wide range. US patent 6667100, filed in 2002, describes how to process expanded graphite to achieve a graphite thickness of one hundred-thousandth of an inch (0.25 nm). The key to success was high-throughput visual recognition of graphene on a properly ...

Physical properties of the two classes of carbons are quite different. Graphitizing carbons are soft and non-porous, while non-graphitizing carbons are hard, low density materials. Non-graphitizing carbons are otherwise known as chars, hard carbons or, more colloquially, charcoal. Glassy carbon is also an example of a non-graphitizing carbon ...
Thermal conductivity (k) 5300 W⋅m −1 ⋅K −1. Graphene (/ ˈɡræfiːn / [1]) is an allotrope of carbon consisting of a single layer of atoms arranged in a honeycomb [2][3] nanostructure. [4] The name is derived from "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon contains numerous double bonds in ...
