EPSRC Equipment Sharing Grant Awarded

Our application to secure funds to refurbish our existing DSC and TGA analysis equipment has been successful.  Sample analysis by TGA/DSC allow detection and characterisation of solvent-loss and phase changes and, as such are complementary to solid-state X-ray crystallography.  The equipment was abandoned by a researcher leaving in 2007 and has not been operational since. … Read the rest

Quasicrystals - Nobel Prize 2011

The Nobel prize for chemistry has been awarded to Daniel Shechtman, from Technion – the Israel Institute of Technology in Haifa, for his discovery of the structure of quasicrystals. Until 1982, it was thought that only two-, three-, four- or six-fold rotational symmetry were possible, however Dr. Schechtman’s discovery changed all that when his electron … Read the rest
