With petroleum-derived plastics becoming ubiquitous, the world is facing a huge problem with both the source and the disposal of these materials. A real alternative is emerging in the form of plastics derived from soybeans, as they are renewable and can also be made to be biodegradable.

The Raman spectra help to identify the chemical composition of a tissue, by producing a vibrational fingerprint consistent with the sum of the individual vibrational spectra produced by the protein, fat and nucleic acids present in it.

Scanning electron microscopy (SEM) is a widely used technique across many scientific fields, including the chemical, nanotechnology and semiconductor sectors. There are many different variations where the operating principles differ slightly from conventional SEM instruments. In this article, we look at cathodoluminescence SEM instruments.

UV printing is a unique method of digital printing utilising ultraviolet (UV) light to dry or cure ink, adhesives or coatings almost as soon as it’s hit the paper, or aluminium, foam board or acrylic - in fact, as long as it fits in the printer, the technique can be used to print on almost anything.

When chemists want to find out what molecules are in a sample and the bonds between them, they might use Raman spectroscopy. The technique utilises laser light to observe changes in the vibrational, rotational or electronic energy of a system to determine which functional groups there are thus providing a structural fingerprint by which the molecule can be recognized.

Leon Goldman first pioneered laser surgery by using lasers to treat cutaneous melanoma, in 1961, in his dermatologic practice. In 1966 he again became the first to use lasers for tumor removal. He went on to become a founder of the American Society for Laser Medicine and Surgery (ASLMS) in 1979.

Cannabis is among the commonest of street drugs to be subjected to chemical analysis. The medical and legalized use of marijuana also requires laboratory testing for the potency of the product. Potency testing helps consumers decide on which product to use for the purpose they have in mind.
