In chemistry, vinyl or ethenyl is the functional group −CH=CH2, namely the ethylene molecule (H2C=CH2) minus one hydrogen atom. The name is also used for any compound containing that group, namely R−CH=CH2 where R is any other group of atoms.
An industrially important example is vinyl chloride, precursor to PVC, a plastic commonly known as vinyl.
Vinyl is one of the alkenyl functional groups. On a carbon skeleton, sp2-hybridized carbons or positions are often called vinylic. Allyls, acrylates and styrenics contain vinyl groups. (A styrenic crosslinker with two vinyl groups is called divinyl benzene.)
The etymology of vinyl is the Latin vinum = "wine", because of its relationship with alcohol (in its original sense of ethyl alcohol). The term "vinyl" was coined by the German chemist Hermann Kolbe in 1851.
Vinyl groups can polymerize with the aid of a radical initiator or a catalyst, forming vinyl polymers. In these polymers, the double bonds of the vinyl monomers turn into single bonds and the different monomers are joined by single bonds. Vinyl groups do not exist in vinyl polymer; the term refers to the precursor. It is sometimes important to ascertain the absence of unreacted vinyl monomer in the final product when the monomer is toxic or reduces the performance of the plastic. The following table gives some examples of vinyl polymers.
Vinyl is a 2012 British comedy film written and directed by Sara Sugarman. It is based on the true story of Mike Peters and The Alarm who in 2004 released the single "45 RPM" under the name of a fictitious band "The Poppy Fields".
The film features a number of past pop and rock stars in cameo roles, such as Steve Diggle (Buzzcocks), Jynine James, Mike Peters and Tim Sanders (The City Zones), along with the actors Phil Daniels, Keith Allen, Perry Benson, Jamie Blackley and Julia Ford.
Vinyl has a soundtrack written and performed by The Alarm with Mike Peters, Phil Daniels and Keith Allen all making contributions.
Filmed mostly on location in Rhyl, it features many local attractions and features. Despite being a USA production the cast is totally British with many of the actors having connections to North Wales, particularly Rhyl. The cast also includes many past members of The Rhyl T.I.C. (Theatre in the Community) which at the time of filming provided many of the younger cast including members of the fake band, the auditionees, security guards, music business employees and of course the fans. The local community of Rhyl also provided location venues in which the crew could film such as The Rhyl Pavilion, Robin Hood Caravan Park, Glan Clwyd Hospital and The Bistro night club. This allowed the film to stay close to the original true story and have the feel of an authentic biog picture.
Vinyl is an American period drama television series created by Mick Jagger, Martin Scorsese, Rich Cohen and Terence Winter. The series stars Bobby Cannavale as Richie Finestra, a record executive in the 1970s. It premiered on HBO on February 14, 2016.
From a teleplay by Terence Winter and George Mastras, and story by Rich Cohen, Mick Jagger, Martin Scorsese and Terence Winter, the pilot episode is directed by Scorsese. The first season will consist of 10 episodes. Scorsese has confirmed plans to direct further episodes of the series.
Night is the period in which the sun is below the horizon.
Night or Nights may also refer to:
Nyx (English /ˈnɪks/;Ancient Greek: Νύξ, "Night";Latin: Nox) is the Greek goddess (or personification) of the night. A shadowy figure, Nyx stood at or near the beginning of creation, and mothered other personified deities such as Hypnos (Sleep) and Thanatos (Death), with Erebus (Darkness). Her appearances are sparse in surviving mythology, but reveal her as a figure of such exceptional power and beauty, that she is feared by Zeus himself.
In Hesiod's Theogony, Nyx is born of Chaos. With Erebus (Darkness), Nyx gives birth to Aether (Brightness) and Hemera (Day). Later, on her own, Nyx gives birth to Moros (Doom, Destiny), Ker (Destruction, Death), Thanatos (Death), Hypnos (Sleep), the Oneiroi (Dreams), Momus (Blame), Oizys (Pain, Distress), the Hesperides, the Moirai (Fates), the Keres, Nemesis (Indignation, Retribution), Apate (Deceit), Philotes (Friendship), Geras (Old Age), and Eris (Strife).
In his description of Tartarus, Hesiod locates there the home of Nyx, and the homes of her children Hypnos and Thanatos. Hesiod says further that Nyx's daughter Hemera (Day) left Tartarus just as Nyx (Night) entered it; continuing cyclicly, when Hemera returned, Nyx left. This mirrors the portrayal of Ratri (night) in the Rigveda, where she works in close cooperation but also tension with her sister Ushas (dawn).
Night (1960) is a work by Elie Wiesel about his experience with his father in the Nazi German concentration camps at Auschwitz and Buchenwald in 1944–45, at the height of the Holocaust toward the end of the Second World War. In just over 100 pages of sparse and fragmented narrative, Wiesel writes about the death of God and his own increasing disgust with humanity, reflected in the inversion of the parent–child relationship as his father declines to a helpless state and Wiesel becomes his resentful teenage caregiver. "If only I could get rid of this dead weight ... Immediately I felt ashamed of myself, ashamed forever." In Night everything is inverted, every value destroyed. "Here there are no fathers, no brothers, no friends," a Kapo tells him. "Everyone lives and dies for himself alone."
Wiesel was 16 when Buchenwald was liberated by the United States Army in April 1945, too late for his father, who died after a beating while Wiesel lay silently on the bunk above for fear of being beaten too. He moved to Paris after the war, and in 1954 completed an 862-page manuscript in Yiddish about his experiences, published in Argentina as the 245-page Un di velt hot geshvign ("And the World Remained Silent"). The novelist François Mauriac helped him find a French publisher. Les Éditions de Minuit published 178 pages as La Nuit in 1958, and in 1960 Hill & Wang in New York published a 116-page translation as Night.
