Diffuse scattering studies of squaric acid in an applied electric field
Organic ferroelectric compounds such as KH2PO4 and squaric acid, have attracted much interest in the past due to their potential in applications [1]. This interest has been... -
Investigation of the hydrogen bonding and anisotropic displacement parameters...
We will investigate the structure of 4-chloroimidazole, which undergoes extreme anisotropic thermal expansion. This is believed from our initial x-ray results to be due to a... -
Low temperature phase transitions in ferroelectric tris-sarcosine calcium chl...
Small-molecule based ferroelectrics offer several advantages over the currently used materials based on heavy metal oxides (i.e. cost, environmental-friendliness). There are... -
Elucidating the Structure of [(LaCl)Ti28O40(OEt)38(X)]; but what is X?
Metal-doped TiO2 have particular applications as in catalysis of a range of reactions as well as in luminescence materials. Our strategy is to make well-defined molecular TixOy... -
Investigating the origin of thermochromism in N-salicylideneanilines
Anils, N-salicylideneanilines, display thermochromism, which is thought to involve an intramolecular proton shift, but to-date the structural changes postulated to occur during... -
Single Crystal Scattering Study of 163-Dy2Ti2O7 Using SXD
Spin ice materials are a class of compounds with exotic magnetic properties, resulting from the frustration. Magnetic monopoles have been detected at low temperature; manifest... -
