Dewar benzene or bicyclo[2.2.0]hexa-2,5-diene is a bicyclic isomer of benzene with the molecular formula CH.
 The compound is named after James Dewar who included this structure in a list of possible CH structures in 1867.
 However, he did not propose it as the structure of benzene, and in fact he supported the correct structure previously proposed by August Kekulé in 1865.
Ariane Daniela Forster (17 January 1962 – 20 October 2010), known by her stage name Ari Up, was a German vocalist best known as a member of the English punk rock band The Slits.
Mount Dewar ( ) is a mountain rising to about 1,600 m to the southwest of Aronson Corner in the Pioneers Escarpment, Shackleton Range.
 It was photographed from the air by the U.S. Navy in 1967 and surveyed by the British Antarctic Survey from 1968–71.
 In association with the names of pioneers of polar life and travel grouped in this area, it was named in 1971 by the UK Antarctic Place-Names Committee after Sir James Dewar, a Scottish chemist and physicist who invented the thermos flask about 1892.
James Dewar (12 October 1942 – 16 May 2002) was a Scottish musician best known as the bassist and vocalist for Robin Trower and Stone the Crows, the latter having its beginnings as the resident band at Burns Howff in Glasgow.
Justin Brady is a British actor who is best known for playing Billy in "The Lakes", James Dewar in "Peak Practice", a paramedic in "Holby City" and he has guest starred in "Shameless".
Andrew "Andy" McMaster (born 27 July 1941) is a Scottish songwriter, best known for writing the lyrics and music of hit songs "Airport" and "Forget About You" by The Motors and co-writing, with Nick Garvey, "Dancing the Night Away", which reached numbers 4, 13 and 42 respectively, in the UK charts between 1977 and 1978.
 The Motors single, "Tenement Steps", was also written by McMaster and peaked at number 17 in the Netherlands chart, in August 1980.
 He also wrote works that were recorded and released by Anita Harris, Alex Harvey, Ducks Deluxe, and James Dewar.
A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings.
 Invented by Sir James Dewar in 1892, the vacuum flask consists of two flasks, placed one within the other and joined at the neck.
 The gap between the two flasks is partially evacuated of air, creating a near-vacuum which significantly reduces heat transfer by conduction or convection.
A cryogenic storage dewar (named after James Dewar) is a specialised type of vacuum flask used for storing cryogens (such as liquid nitrogen or liquid helium), whose boiling points are much lower than room temperature.
 Cryogenic storage dewars may take several different forms including open buckets, flasks with loose-fitting stoppers and self-pressurising tanks.
 All dewars have walls constructed from two or more layers, with a high vacuum maintained between the layers.
 This provides very good thermal insulation between the interior and exterior of the dewar, which reduces the rate at which the contents boil away.
 Precautions are taken in the design of dewars to safely manage the gas which is released as the liquid slowly boils.
 The simplest dewars allow the gas to escape either through an open top or past a loose-fitting stopper to prevent the risk of explosion.
 More sophisticated dewars trap the gas above the liquid, and hold it at high pressure.
 This increases the boiling point of the liquid, allowing it to be stored for extended periods.
 Excessive vapour pressure is released automatically through safety valves.
 The method of decanting liquid from a dewar depends upon its design.
 Simple dewars may be tilted, to pour liquid from the neck.
 Self-pressurising designs use the gas pressure in the top of the dewar to force the liquid upward through a pipe leading to the neck.
Sir James Dewar FRS FRSE (20 September 1842 – 27 March 1923) was a Scottish chemist and physicist.
 He is probably best known today for his invention of the vacuum flask, which he used in conjunction with extensive research into the liquefaction of gases.
 He was also particularly interested in atomic and molecular spectroscopy, working in these fields for more than 25 years.
Solid hydrogen is the solid state of the element hydrogen, achieved by decreasing the temperature below hydrogen's melting point of 14.01 K .
 It was collected for the first time by James Dewar in 1899 and published with the title "Sur la solidification de l'hydrogène" (English: On the solidification of hydrogen) in the "Annales de Chimie et de Physique", 7th series, vol.
 18, Oct. 1899.
 Solid hydrogen has a density of 0.086 g/cm making it one of the lowest-density solids.
