Dewar, Sir James (1842-1923) British chemist and physicist, born in Scotland. In 1875 he became a professor at (Dambridge University, while carrying out much of his experimental work at the Royal Institution in London. He began studying gases at low temperatures and in 1872 invented the Dewar flask. In 1891, together with Frederick Abel (1827-1902), he developed the smokeless propellant explosive cordite, and in 1898 was the first to liquefy hydrogen.

Since black powder is relatively low in energy, it leaves a large proportion of corrosive solids after explosion and absorbs moisture readily, it was succeeded in late 1800s by smokeless gunpowder and picric acid. The first smokeless powder, known as cordite, was invented by tbe English chemists Sir James Dewar and Sir Frederick Augustus Abel in 1889. It was made in two forms a gelatinized nitrocellulose and a mixture of NC and NG with a small quantity of petroleum jelly added to act as a stabilizer. Smokeless powder soon became tbe primary ammunition for use in pistols. 

Sir James Dewar was born in Kincardine, Scotland, on September 20, 1842, the son of an innkeeper. He attended local schools until he was ten when he suffered a serious case of rheumatic fever lasting two years. During this period he built a violin, and music remained a lifelong interest of his. In 1858 he entered the University of Edinburgh. There he studied physics and chemistry. Dewar, in an early display of his dexterity, developed a mechanical model of Alexander Crum Brown s graphic notation for organic compounds. This was sent to Friedrich Kekule in Ghent who then invited Dewar to spend some time in his laboratory.

Cordite, the smokeless powder adopted by the British Government, is the patent of the late Sir F.A. Abel and Sir James Dewar, and is somewhat similar to blasting gelatine. It is chiefly manufactured at the Royal Gunpowder Factory at Waltham Abbey, but also at two or three private factories, including those of the National Explosives Company Limited, the New Explosives Company Limited, the Cotton-Powder Company Limited, Messrs Kynock s, c. As first manufactured it consisted of gun-cotton 37 per cent., nitro-glycerine 58 per cent., and vaseline 5 per cent., but the modified cordite now made consists of 65 per cent, gun-cotton, 30 per cent, of nitro-glycerine, and 5 per cent, of vaseline. The gun-cotton used is composed chiefly of the... 

Heat transfer to the surroundings is reduced to a minimum the walls of the vessel consist of two thin layers of glass (or, in large vessels, steel) separated by a vacuum to reduce conduction and convection the inner surface of a glass vessel is silvered to reduce radiation and the vessel is stoppered to prevent evaporation. It was devised around 1872 by Sir James Dewar and is also known by its first trade name Thermos flask. See also cryo-...
