Dyneema or Spectra is a synthetic fiber, 15 times stronger than steel and three times stronger than Kevlar. It is usually used in bulletproof vests, bow strings and sails on high-performance yachts. Dyneema was invented by DSM in 1979. It has been in commercial production since 1990 at a plant in Heerlen, the Netherlands. In the Far East, DSM has a cooperation agreement with Toyobo Co. for commercial production in Japan. In the United States, DSM has granted a license to Allied Signal. ...

| spectroscopy |
The study of the interaction between matter and radiation. Since the energy levels in all atoms and molecules are discrete (quantized), the absorption or emission of radiation occurs at distinct energies (frequencies) characteristic of a given chemical. The energy levels probed may be rotational (microwave region), vibrational (infrared region), or electronic (visible or ultraviolet). ...
