The project aims to prepare polymer solar cells, by developing water-compatible conjugated materials for the active layer. This technology would be cost-efficient and not use environmentally harmful solvents. The project would achieve aqueous compatibility of these hydrophobic molecules through substitution and careful positioning of functional groups. Fabrication processes will be optimised to incorporate these materials into solar cells, with a focus on controlling the morphology of the active material. Determining the relationships between conjugated molecular design and cell performance should provide a new direction in solar-cell technology.Read moreRead less

Reducing gas and ash corrosion in advanced power generation. Advanced power generation using new coal combustion technologies increases energy efficiency and makes carbon dioxide capture possible, but increases the corrosion problems. This project aims to determine the corrosion behaviour of chromia-scale forming iron- and nickel-base alloys in the presence of deposits (coal ashes and salts) under carbon dioxide rich gas atmospheres.

Advanced power generation using new coal combustion technologies increases energy efficiency and makes carbon dioxide capture possible, but increases the corrosion problems. This project aims to determine the corrosion behaviour of chromia-scale forming iron- and nickel-base alloys in the presence of deposits (coal ashes and salts) under carbon dioxide rich gas atmospheres. The increased understanding of alloy behaviour in hot corrosive ashes and gases, will permit more effective materials design and selection leading to more efficient and economic technologies for reliable and low cost carbon capture in energy production, waste-energy conversion and related industries.Read moreRead less

Using anisotropic thermal expansion in organic semiconductor thin films. This project aims to capitalise upon the recent discovery of negative thermal expansion in high-performance organic semiconductor films. Certain molecules’ chemical structures have a planar conjugated core and flexible sidechains. When highly anisotropic thermal expansion occurs, the sidechains take up most of the thermal expansion. When a negative thermal expansion occurs, the pi-pi stacking distance decreases upon anneali ....Using anisotropic thermal expansion in organic semiconductor thin films. This project aims to capitalise upon the recent discovery of negative thermal expansion in high-performance organic semiconductor films. Certain molecules’ chemical structures have a planar conjugated core and flexible sidechains. When highly anisotropic thermal expansion occurs, the sidechains take up most of the thermal expansion. When a negative thermal expansion occurs, the pi-pi stacking distance decreases upon annealing. This effect has been linked with higher charge mobilities, and a tighter molecular packing is locked in upon cooling. The potential applications of these high performance organic semiconductors includes chemical/biosensors, electronic paper, and radio frequency identification cards.Read moreRead less
Heat-resisting iron-nickel base alloys in challenging new applications: oxygen permeabilities and resistance to internal oxidation. There is a pressing need to develop heat resisting alloys which can function adequately in higher operating temperatures and gas mixtures rich in carbon and hydrogen to be handled in advanced technologies for power generation. The expected outcomes of this project will provide the basis for design/selection of these more corrosion-resistant alloys.

This project seeks to develop a new class of electron field emitting nanocomposite consisting of nanotubes in liquid crystalline polymers. Electron emitting materials are in much demand in x-ray and microwave generation, computer displays and low-energy lighting. We utilise the ready alignability of liquid crystalline units in magnetic fields to cause realignment of incorporated carbon nanotubes, followed by polymer solidification to maintain orientation. It involves low temperature processing, contrasting very favourably with current problematic, high temperature processes. This allows materials to be cast on flexible polymer substrates, potentially enabling construction of cathode tubes to replace existing mercury-containing fluorescent lighting.Read moreRead less

The aim of this project is to prepare iron-based magnetic nanostructures that exhibit a magnetic induction of 1.9 tesla and core losses lower than those of iron-silicon steels, which would deliver smaller and efficient magnetic cores for petrol-electric hybrid cars. Preliminary results from the research team show that iron-metalloid alloys with an iron content of 87 per cent meet this magnetic induction with room for further improvement of magnetic softness. The project aims to systematically investigate the effect of metalloid and micro-alloying elements on the nano-crystallisation behaviour of the precursor amorphous alloys in order to identify the alloy composition and processing conditions for preparing magnetically soft nanostructures.Read moreRead less
