In 1957, a group of scientists at the Nobel Institute of Physics in Sweden discovered a new element with a half-life of 10 min by bombarding curuim-244 atoms with carbon-13 ions in a cyclotron.

Arthur C. Wohl, Edward M. McMillan, Joseph W. Kennedy and Glenn T. Seaborg first discovered plutonium at the University of California in 1941.They bombarded uranium-238 atoms with deuterons in a 60-inch cyclotron and created neptunium-238 and two free neutrons.

Meitnerium was first discovered by Gottfried Münzenber and Peter Armbruster at Heavy Ion Research Laboratory in Darmstadt, Germany in 1982. They bombarded bismuth-209 atoms with iron-58 ions in a linear accelerator and produced meitnerium-266 atoms with free neutrons.

Neon was first discovered by Morris Travers and William Ramsay in 1898 shortly after the discovery of krypton in the same year. They both froze argon sample with the help of liquid air and slowly evaporated argon under low pressure to collect the new gas.

Polymethylpentene (PMP) is a thermoplastic polymer of methylpentene monomer units. TPX is a commonly used trademark provided by Mitsui Chemicals. Other trademark names of PMP are Zeonex and Crystalor.
Polyester is a plastic that was invented in the UK back in the 1940s, and is considered as one of the greatest man-made inventions. It is a long- chain synthetic polymer consisting at least 85% by weight ester and terephthalic acid.
Oxygen was discovered by Joseph Priestley in 1744. Carl W. Scheele of Sweden found the presence of the element two years before, but failed to publish it. Scheele found a gas that enhances combustion while heating several compounds, including mercury oxide, manganese oxide and potassium nitrate.
