Nitroglycerin (NG) (alternative spelling of nitroglycerine), also known as trinitroglycerol (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless or pale yellow, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid under conditions appropriate to the formation of the nitric acid ester.
Gelatinised nitrocellulose is a plastic, which can be formed into cylinders, tubes, balls, or flakes known as single-base propellants. The size and shape of the propellant grains can increase or decrease the relative surface area, and change the burn rate significantly. Additives and coatings can be added to the propellant to further modify the ...
This led the French military to conclude it was unsuitable for military use (indeed, it was a problem for all the militaries which tried to use double- base propellants later). [4] Nobel subsequently licensed the rights to the Italian government, which entered into a contract on 1 August 1889 to obtain 300,000 kg (660,000 lb) of Ballistite; and ...
A single based fuel/propellant has nitrocellulose as its chief explosives ingredient. Stabilizers and other additives are used to control the chemical stability and enhance its properties. Double-based fuel/propellant Double-based fuel/propellants consist of nitrocellulose with nitroglycerin or other liquid organic nitrate explosives added.
A nitrocellulose slide, nitrocellulose membrane, or nitrocellulose paper is a sticky membrane used for immobilizing nucleic acids in southern blots and northern blots. It is also used for immobilization of proteins in western blots and atomic force microscopy [ 15 ] for its nonspecific affinity for amino acids .
Before and during World War I, the gun used about 56.6 kg (125 lb) of RP C/12 (Rohr-Pulver – tube powder) [2] propellant that was a mix of nitrocellulose, nitroglycerin and small amounts of other additives with a calorific value of 950 and an uncooled explosion temperature of 2,975 kelvins. [5]
Topical cream formulation is an emulsion semisolid dosage form that is used for skin external application. Most of the topical cream formulations contain more than 20 per cent of water and volatiles and/or less than 50 per cent of hydrocarbons , waxes , or polyethylene glycols as the vehicle for external skin application.

During the 1930s, triple-base propellants containing nitrocellulose, nitroglycerin or diethylene glycol dinitrate, and a substantial quantity of nitroguanidine (detonation velocity 8,200 m/s (26,900 ft/s), RE factor 0.95) as explosive propellant ingredients were commercialized.
