Cooperativity in Spin Crossover Systems: Memory, Magnetism and Microporosity. Spin-crossover centres are a well known form of inorganic electronic switch for which variation of temperature, pressure and irradiation leads to a change in d-electron configuration and therefore changes to structure, colour and magnetism.

Spin-crossover centres are a well known form of inorganic electronic switch for which variation of temperature, pressure and irradiation leads to a change in d-electron configuration and therefore changes to structure, colour and magnetism. Here we aim to synthesise and study a wide variety of new spin-crossover systems where cooperativitiy between centres, induced by careful supramolecular design, will lead to molecules and materials having memory retention, magnetic ordering and/or microporosity. The significance of these aims covers several fundamental questions in the science of electronic systems. We also identify a number of potential nanochemical switching applications for the unique systems proposed.Read moreRead less

Breakthrough microprobe and nanoprobe technologies, involving X-ray, visible and infrared light can focus into different components of mammalian cells in order to interrogate the biochemistry that is occurring therein. Each of the different wavelengths of light provides complementary biochemical information that enables multi-layered information on changes in cells that occur as a function of drug treatments and disease processes. This will provide unprecedented information as to where drugs go and how they are transformed inside cells that, in turn, may revolutionalise the way in which new drugs are designed that have higher specificity and lower side effects.Read moreRead less
