H. F. Maltby

Henry Francis Maltby (25 November 1880 – 25 October 1963) was a prolific writer for the London stage and British cinema from after the First World War, until the 1950s. He also appeared in many films.

Life and career

Born in Ceres, Cape Colony (later to be part of South Africa), Maltby was educated at Bedford School. He was married twice, to Billie Joyce and Norah M. Pickering. Maltby served in France, as a bombardier.

Playwriting career

On his return to Britain, Maltby wrote and performed in many plays for the West End theatre, some achieving success and transferring to Broadway. He wrote The Rotters in 1915, but it took nearly a year to get it to the provincial stage. The play was a success and transferred to the Garrick Theatre in the West End, playing for 86 performances and toured for the next decade, also being made into a film. The theme is satirical, dealing with a dysfunctional family and their minor 'sins' revolving around the father's obsessive respectability. The play received a tepid review from The Times, which found it formulaic, but it was popular with audiences. He also wrote an all-woman farce, Petticoats with women taking over the state (with the men away at war).

Fluoronium

Fluoronium (systematically named fluoranium, and μ-fluorido-dihydrogen(1+)) is an inorganic cation with the chemical formula H
2F+
(also written [H
2F]+
). It contributes no colour to fluoronium salts. It is a very strong acid, and dilute fluoronium solutions are corrosive and can attack the skin. It can be formed by protonation or self-ionic dissociation of hydrogen fluoride:

or

The fluoronium ion is isoelectronic with water and the amide ion.

Whereas stable organic structures containing other halonium ions have been known since 1970, a fluoronium analog was not known until 2013 and even then only as an unstable short-lived entity.

The kinetic instability of the fluoronium ion is responsible for the extreme acidity of fluoroantimonic acid. The antimony pentafluoride molecule sequesters the fluoride ion produced by the homoassociation of hydrogen fluoride, leaving the fluoronium ion unable to revert to the more stable neutral hydrogen fluoride.
