Cyanide

A cyanide is any chemical compound that contains monovalent combining group CN. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom.

In inorganic cyanides, such as sodium cyanide and potassium cyanide this group is present as the negatively charged polyatomic cyanide ion (CN⁻); these compounds, which are regarded as salts of hydrocyanic acid, are highly toxic. The cyanide ion is isoelectronic with carbon monoxide and with molecular nitrogen.

Organic cyanides are usually called nitriles; in these, the CN group is linked by a covalent bond to a carbon-containing group, such as methyl (CH₃) in methyl cyanide (acetonitrile). Because they do not release cyanide ions, nitriles are generally less toxic, or in the case of insoluble polymers such as acrylic fiber, essentially nontoxic unless burned.

Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid used to prepare acrylonitrile, which is used in the production of acrylic fibers, synthetic rubber, and plastics. Cyanides are employed in a number of chemical processes, including fumigation, case hardening of iron and steel, electroplating, and the concentration of ores. In nature, substances yielding cyanide are present in certain seeds, such as the pit of the cherry and the seeds of apples.

Cyanide (company)

Cyanide is a French video game development studio and publisher that was created by seven ex-UbiSoft employees and is based in the western suburbs of Paris, France, with offices in Montreal, Canada and Chengdu, China.

They have developed games in numerous genres, including sports management, real time strategy, fantasy, and action RPG.

Cyanide (film)

Cyanide (Kannada: ಸೈನೈಡ್), Kuppi (Tamil) is a 2006 Indian bilingual drama film written and directed by A. M. R. Ramesh. The plot of the film set in and around Bangalore from 1 August to 20 August 1991, deals with incidents surrounding the assassins of former Indian Prime Minister Rajiv Gandhi. It stars Ravi Kale as Sivarasan (One-eyed Jack), the mastermind of the assassination. Malavika Avinash, Tara, Rangayana Raghu in pivotal roles. The supporting cast features Avinash, Nasser and Suresh Heblikar.

Upon theatrical release on 7 July 2006, the film received widespread critical acclaim. Critics acclaimed the film's narration, the acting performances of Ravi Kale, Rangayana Raghu, Tara and Malavika Avinash, and the camerawork and editing of the film. At the 2006–07 Karnataka State Film Awards the film won two awards — Third Best Film and Best Actress (Tara). For his portrayal of Ranganath, who sheltered the assassins, Raghu was awarded the Best Supporting Actor at the 54th Filmfare Awards South. The film is seen by some critics as one of the finest films ever made in Kannada cinema.

Die (integrated circuit)

A die in the context of integrated circuits is a small block of semiconducting material, on which a given functional circuit is fabricated. Typically, integrated circuits are produced in large batches on a single wafer of electronic-grade silicon (EGS) or other semiconductor (such as GaAs) through processes such as photolithography. The wafer is cut (“diced”) into many pieces, each containing one copy of the circuit. Each of these pieces is called a die.

There are three commonly used plural forms: dice, dies, and die.
