Graphene is the thinnest material known to exist, whilst also being extremely strong - around 200 times stronger than steel. Graphene is an excellent conductor of electricity and heat as is optically transparent. The applications of graphene are extensive, and include energy storage, photodetectors, and computer chips.

Semicrystalline polymers are the largest group of commercially produced plastics. Heating and cooling of these polymers between phase transitions is used industrially to shape polymers into their final product. In this application note the RMS1000, with a heated stage, is used to observe phase transitions in two polymers; polyethylene, and nylon-6.

Microplastic pollution is a growing environmental issue. Identification is crucial for assessing their risk to the environment, wildlife, and mankind. Raman microscopy is a great tool for the identification of small microplastics. This application note explores how the RM5 Raman Microscope combined with the KnowItAll Raman database can be used to identify polymers commonly found in the Earths aquatic systems.
