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 it is optically transparent. The applications of graphene are extensive, and include energy storage, photodetectors, and computer chips. In this application note we highlight how Raman microscopy is an essential tool for any material scientist researching graphene.

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.

Researchers in Fujian, China, led by Rong Cao and Zu-Jin Lin, have developed a new method for sensing ClO- employing fluorescence spectroscopy and novel metal organic frameworks. The authors used an Edinburgh Instruments FS5 Spectrofluorometer to characterize and optimise the sensor’s response towards ClO- . They then employed this sensor to detect ascorbic acid, an essential nutrient for the human body.
