The Challenge

Chemistry is at the heart of collaborative research to create smart materials with a range of properties for applications in modern technologies.

Use of non-toxic biosourced microcapsules to replace petroleum-based chemicals and materials

Discovering the limits of stability and reactivity for small molecules.

The Approach

The approach is a collaborative research with Chemistry at the heart of all activities. Chemistry is the vital discipline thanks to which new materials with a range of properties are created and can be tested for applications in every-day activities.

 

Impact

Examples of smart materials created within this research theme include (but are not limited to) new materials for fast switching devices, new catalysts for the synthesis of vitamin E, smart soaps, artificial leaf devices for hydrogen generation from surface-immobilised microalgae.
