Gallium nitride (GaN) is a wide bandgap semiconductor that is the material responsible for the blue light-emitting diode (LED), a Nobel prize-winning discovery. As well as being used extensively in the photonics industry, it has promise as a potential replacement for silicon in components where small sizes and high energy densities are required, as well as in environments where external

In this Map of the Month, a formulation containing the API cetirizine (CTZ) hydrochloride, a widely used antihistamine, was imaged using the Edinburgh Instruments RM5 Confocal Microscope.

In January’s Map of the Month, we look forward to the longer days by analysing strain in a standard solar cell semiconductor material: silicon.

Edi’s been making a mess in the kitchen! Baking up some Christmas goodies we’ve had a few spills along the way. But what did they spill? Let’s find out with the RM5!

In November’s Map of the Month, we celebrate the coming of autumn by photoluminescence imaging chlorophyll in a fallen leaf.

Can you believe Map of the Month is 2 years old? Neither can we! To celebrate we asked some of the team to look back and pick their favourite map so far …

The forgery of documents is a common problem for the police, customs officials, and historians, and they are very difficult to detect by eye. Here we show how photoluminescence spectroscopy can be used to detect an ink forgery without damaging the sample.

Nasal relief sprays reduce the symptoms of hay fever and colds. Read this Map of the Month blog to find out how they do this, and how Raman mapping can be used to track the distribution of the active pharmaceutical ingredient.

Despite being a major cause of seasonal allergies, the distribution of microscopic pollen particles is crucial for biodiversity. Read our latest Map of the Month blog to find out how Raman spectroscopy can be used to study pollen grains and aid researchers in species identification.

Emulsions are phase-separated liquid in liquid mixtures that are found naturally in different foods and are often used in the formulation of cosmetics and medicines. Confocal Raman microscopy is an excellent technique for providing 3-dimensional chemical images of emulsions, and it can inform manufacturers about the morphology and distribution of liquid particles in their products.
