Silene is a genus of plants.
Silene may also refer to:
In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition. This enables systematic prediction of chemical reactions and behavior of chemical compounds and the design of chemical synthesis. The reactivity of a functional group can be modified by other functional groups nearby. Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis.

Selonia, also known as Augšzeme, is one of the Historical Latvian Lands encompassing the eastern part of the historical region of Semigallia as well as a portion of northeastern Lithuania. Its main city and cultural center is Jēkabpils. The Selonian language has become extinct, though some of the inhabitants still speak a Latgalian dialect.
Organosilicon chemistry is the study of organometallic compounds containing carbon–silicon bonds, to which they are called organosilicon compounds. Most organosilicon compounds are similar to the ordinary organic compounds, being colourless, flammable, hydrophobic, and stable to air. Silicon carbide is an inorganic compound.

Disilyne is a silicon hydride with the formula Si
2H
2. Several isomers are possible, but none are sufficiently stable to be of practical value. Substituted disilynes contain a formal silicon–silicon triple bond and as such are sometimes written R2Si2 (where R is a substituent group). They are the silicon analogues of alkynes.

The municipality was formed in 2009 by merging Abava parish, Balgale parish, Ģibuļi parish, Īve parish, Ķūļciems parish, Laidze parish, Lauciene parish, Lībagi parish, Lube parish, Strazde parish, Valdgale parish, Vandzene parish, Virbi parish, Talsi town, Stende town, Sabile town and Valdemārpils town with its countryside territory. In 2021 the municipality was expanded to include the former Dundaga municipality, Mērsrags municipality and Roja municipality. The administrative centre of the municipality is Talsi city. The population in 2022 was 35,194.
Vaiņode is a village in Vaiņode Parish, South Kurzeme Municipality in the Courland region of Latvia. The village developed around a railway station after 1871 between Liepāja and Mažeikiai.
Disilene is an inorganic compound with the chemical formula Si
2H
4. The name disilene, referring to the structure of a particular prototropic tautomer of the molecule. It is the simplest silene.
Mallojaponin is a hydrolysable tannin found in the bark of Mallotus japonicus. This compound contains the moiety elaeocarpusinic acid, an oxidized hexahydroxydiphenic acid group which reacted with a dehydroascorbic acid molecule. It also contains a valoneic acid and a gallic acid moieties linked to a glucose molecule.

Group 14 hydrides are chemical compounds composed of hydrogen atoms and group 14 atoms.
Silanes refers to diverse organosilicon charge-neutral compounds with the formula SiR
4. The R substituents can any combination of organic or inorganic groups. Most silanes contain Si-C bonds, and are discussed under organosilicon compounds. Some contain Si-H bonds and are discussed under hydrosilanes.
