Probing the structure of calcium silicates over a wide range of length scales.
Sol-gel derived calcium silicates are of great importance due to their ability to bond to bone and stimulate new bone growth. Diffraction has revealed the atomic-scale changes... -
The Effect of Pressure on the Crystal Structure of Serine Hydrate
Serine monohydrate undergoes a phase transition at 5.2 GPa which involves reorientation of water molecules. It appears that this disrupts H-bonding elsewhere in the crystal,... -
