What was the name of the substance that Stephanie Kwolek discovered?
Stephanie Kwoleck discovered properties of polymers to enable her to develop the first liquid crystal polymer. Her discovery led to the devlopment of Kevlar aramid fibre, with its very light threads which are stronger than steel. This fibre has been used to build spacecraft and bullet-proof vests.
How nucleic was discovered?
Nucleic acids were discovered by Friedrich Miescher in 1869. He isolated a substance from the nuclei of cells that contained high amounts of phosphorus, which he called nuclein. Later, this substance was found to be composed of nucleic acids, which carry genetic information in cells.
Who first discovered nuclein?
Friedrich Miescher, a Swiss biochemist, first discovered nuclein in 1869. He isolated a substance now known as DNA from the nuclei of white blood cells.
Which company owns Kevlar?
E. I. du Pont de Nemours and Company Stephanie Kwolek invented the syntheticWhile working for DuPont, Kwolek invented Kevlar. In anticipation of a gas shortage, in 1964 her group began searching for a new lightweight strong fiber to use for light but strong tires. The polymers she had been working with at the time, poly-p-Phenylene-terephthalate and polybenzamide, formed liquid crystal while in solution, something unique to those polymers at the time. The solution was "cloudy, opalescent upon being stirred, and of low viscosity" and usually was thrown away. However the technician, Charles Smullen, who ran the "spinneret" persuaded Kwolek to test her solution, and was amazed to find that the fiber did not break, unlike nylon. Both her supervisor and laboratory director understood the significance of her discovery and a new field of polymer chemistry quickly arose. By 1971, modern Kevlar was introduced. However, Kwolek was not very involved in developing the applications of Kevlar.Stefan Kevlar
What element was discovered in 1669 by Brandt?
Phosphorus was discovered in 1669 by Hennig Brandt, a German alchemist, while he was trying to create the philosopher's stone. He discovered it by distilling urine multiple times, resulting in a white substance that glowed in the dark.
