Roy J. Plunkett and the Discovery of Teflon

On June 26, 1910, American chemist Roy J. Plunkett was born. He is best knwon for his 1938 accidentally discovery of polytetrafluoroethylene (PTFE), better known under the DuPont Co. trademark Teflon. PTFE is used as a non-stick coating for pans and other cookware as well as PTFE has one of the lowest coefficients of friction against any solid.

Alfred Nier – a Pioneer in Mass Spectroscopy

Alfred Nier – a Pioneer in Mass Spectroscopy

On May 28, 1911, American physicist Alfred Otto Carl Nier was born. Nier pioneered the development of mass spectrometry. He was the first to use mass spectrometry to isolate uranium-235 which was used to demonstrate that 235U could undergo fission and developed the sector mass spectrometer configuration now known as Nier-Johnson geometry. “…You try to untangle all of these processes to get at the primordial ratio of the heliums in the cosmic…

Hermann Staudinger and the Macromolecules

Hermann Staudinger and the Macromolecules

On March 23, 1881, German organic chemist Hermann Staudinger was born. Staudinger demonstrated the existence of macromolecules, which he characterized as polymers. For this work he received the 1953 Nobel Prize in Chemistry. He is also known for his discovery of ketenes and of the Staudinger reaction. “The most fundamental difference between compounds of low molecular weight and macromolecular compounds resides in the fact that the latter may exhibit properties that cannot…

Wallace Hume Carothers and the Invention of Nylon

Wallace Hume Carothers and the Invention of Nylon

On April 27, 1896, American chemist and inventor Wallace Hume Carothers was born. He is credited with the invention of nylon, the first synthetic polymer fibre to be spun from a melt. Carothers produced this polyamide, by condensation of adipic acid and hexamethylenediamine working for the DuPont chemical company  as head of organic chemistry research. “Living in the midst of abundance we have the greatest difficulty in seeing that the supply of…

Plastic Fantastic – Leo Baekeland and the Beginning of the Plastic Age

Plastic Fantastic – Leo Baekeland and the Beginning of the Plastic Age

On November 14, 1863, Belgian-born American chemist Leo Henricus Arthur Baekeland was born. His invention of Bakelite, an inexpensive, nonflammable, versatile, and popular plastic, marked the beginning of the modern plastics industry. Back in the eighties and nineties, the phrase plastic-fantastic was coined to describe a cheap item that more than often broke when you started using it because the early day plastic was so brittle. However, bakelite was different… The Velox Photography Paper The…

How Crick and Watson deciphered the DNA

How Crick and Watson deciphered the DNA

On February 28, 1953,  American molecular biologist James D. Watson and English biophysicist Francis Crick announced to friends that they succeeded to determine the chemical structure of DNA. “When finally interpreted, the genetic messages encoded within our DNA molecules will provide the ultimate answers to the chemical underpinnings of human existence.” – James D. Watson, in [11] DNA and RNA – the Prelude In 1869, the Swiss physician Friedrich Miescher discovered a…
