Title: Julian Hill recreating synthesis of first completely synthetic fiber
Date(s): 1941
Contributor(s): E.I. du Pont de Nemours & Company (originator)
Description: Probably the most dramatic moment in DuPont research history is re-enacted above-the birth of the first completely synthetic fiber, impractical for commercial use but true forerunner of nylon itself. Here chemist Julian Hill shows how he pulled molten sample of material from a laboratory test tube at the company's Experimental Station near Wilmington, Delaware. The molasses-like mass stuck to the glass stirring rod and was drawn out into a thin fiber.

Title: Testing the strength of TD nickel
Date(s): 1960/1969, 1960, 1969
Contributor(s): E.I. du Pont de Nemours & Company (originator)
Description: A graphic demonstration of the high temperature strength of TD nickel, DuPont's new alloy of 98% nickel and 2% thorium. The TD nickel bar reaches red heat, but does not fail at 2,100 degrees Fahrenheit under a load of 6,000 pounds per square inch. The best super alloys now used in high temperature service failed under similar test conditions at DuPont's Metal Center in Baltimore.

Title: The flame of an acetylene torch is shot through a tube of TD nickel
Date(s): 1960/1969, 1960, 1969
Contributor(s): E.I. du Pont de Nemours & Company (originator)
Description: The flame of an acetylene torch is shot through a tube of TD nickel, a new alloy, in a demonstration of the metal's stability at high temperatures. The new metal, produced at the DuPont Metals Center in Baltimore, is designed for use in space vehicles operating at elevated temperatures. The technique for improving the strength of nickel involves the dispersion of particles of thorium oxide, one millionth of an inch in diameter, uniformly within the grain structure of the material, The...
Show moreThe flame of an acetylene torch is shot through a tube of TD nickel, a new alloy, in a demonstration of the metal's stability at high temperatures. The new metal, produced at the DuPont Metals Center in Baltimore, is designed for use in space vehicles operating at elevated temperatures. The technique for improving the strength of nickel involves the dispersion of particles of thorium oxide, one millionth of an inch in diameter, uniformly within the grain structure of the material, The dispersion techniques can be applied to other metals and alloys. The process is described by DuPont as a major breakthrough in high temperature metallurgy.

Title: Measuring the energy of an explosive by ballistic mortar
Date(s): 1896
Contributor(s): E.I. du Pont de Nemours & Company (originator)
Description: The energy of an explosive is commonly measured by shooting a definite amount in a ballistic mortar, a heavy swinging cannon, expelling a close fitting projectile into a sand pile, and observing how much swing is imparted to at the mortar by the recoil of the cannon- the greater the swing, the greater the energy. The above photograph, taken in 1896 at the Old Repauno Works Laboratory of the DuPont Company, near Gibbstown, New Jersey, shows the recoil of a ballistic mortar caused by firing a...

Title: DuPont lab team discussing results of an experiment
Date(s): 1955
Contributor(s): E.I. du Pont de Nemours & Company (originator)
Description: The industrial chemist today stands in sharp contrast with the lone wolf inventor common even a little more than a generation ago. Although the initiative and creative thought of the individual is still of prime importance, the modern researcher is a team player with a strong sense of cooperative effort. Pictured here is a DuPont lab team discussing results of an experiment.
