Porous materials such as zeolites, activated carbons and metal-organic frameworks (MOFs) have been shown to be potentially useful in a wide variety of different applications, including gas separation, energy storage and catalysis. In these applications, pores of different sizes and geometries play a crucial role in the capture and diffusion of guest molecules. In this topic, we are interested in exploring the possibility of enhancing the mass transfer and the gas storage capacity of existing nanoporous materials, creating materials for improved catalytic performance and selective gas storage. We are also interested in collborative projects on characterisation techniques (such as neutron spectroscopy) to study the behaviour of guest molecules in porous materials with a diversity of pore characteristics. Such fundamental investigations aim to improve the understanding of how the nanoporous structure of different storage materials can influence sorption and catalytic capacities, leading to more accurate evaluation methods as well as potentially informing the design of new porous materials.
Luminescent materials and photonic architecture for light emitting application
Energy-efficient and environmentally friendly light sources are an essential part of the global strategy to reduce the worldwide electricity consumption. Light-emitting diodes (LEDs) emerge as a key alternative to conventional lighting, due to their high power-conversion efficiency, long lifetime, fast switching, robustness, and compact size. Nonetheless, their implementation in the consumer electronic industry is hampered by the limited control over brightness, colour quality and directionality of LED emission that conventional optical elements relying on geometrical optics provide. By combining reliable and tunable emission of rare-earth nanocrystals and photonic architectures, we seek to explore new ways of controlling their emission characteristics and addressing the critical shortcomings of current LEDs.
