Targeting Bio-Compatible Homo- and Hetero-bimetallic Cages and their Application in High Energy and Dual Energy Computed Tomography. The project is focused on the synthesis, characterisation and stability of novel homo-metallic and hetero-metallic oxygen and sulfur based cage compounds which have the potential to be suitable for high energy and Dual Energy CT imaging (DECT), and also for optical imaging where rare-earth metals are involved.

The project is focused on the synthesis, characterisation and stability of novel homo-metallic and hetero-metallic oxygen and sulfur based cage compounds which have the potential to be suitable for high energy and Dual Energy CT imaging (DECT), and also for optical imaging where rare-earth metals are involved. Pre-requisites for cage design are that they be stable and soluble in aqueous media, and be resistant to anionic ligand exchange at the cluster surface. The targeted metals are based on good attenuation at high (100 to 140 keV) and low X-ray (less than 30 keV) energies, and the possibility of high stability and low toxicity.Read moreRead less

National magnetochemical facility. New magnetic materials of the molecular or biological types are quite different to traditional metal oxide magnets widely used, for example, in recording devices. They are very important from the perspective of understanding fundamental properties at low temperatures, in high magnetic fields, or when irradiated by light, but they are also showing promise in a range of applications, such as memory devices and smart cards and in the new area of spintronics and m ....National magnetochemical facility.
