Welcome to Soft Condensed Matter

The Soft Condensed Matter Group provides the infrared (IR) and Circular Dichroism (CD) spectroscopy and, both Small and Wide Angle X-ray Scattering (SAXS and WAXS) imaging capabilities of Diamond. The Soft Condensed Matter Group comprises of four beamlines B21, B22, I22 and B23. This unique portfolio of beamlines can analyse a range of samples that include two-dimensional thin films (photovoltaics), living mammalian cells, three-dimensional matrices (metal-organic frameworks) and nano-particles in non-crystalline states. The Soft Condensed Matter Group maintains a dedicated laboratory space for our visiting users. The laboratory houses vital equipment for sample preparation and analysis such as a centrifuges, a small tissue-culture facility, spectroscopy equipment (including CD, standalone IR and UV spectroscopy, multi-angle and quasi-elastic light scattering) and the ability to work with different gases. Laboratory and offline instrumentation usage can be reserved through the User Administration System at any time throughout the operational year of Diamond. Since the start of 2017, both B21 and B23 now offer mail-in services for solution-state SAXS and CD measurements.
