Modelling the Transient Effects in Dense Phase Gas-Solids Flow in Pipelines. Almost every physical item we use in our daily lives at some point requires the transport and handling of powdered or granular materials during the manufacturing process. Be it food (sugar, flour), chemicals (soap powders, detergents), cosmetics (talc, face powder) or electricity generation (coal and ash); each of these industries uses the flexibility of pipeline systems to transport powders and granular solids using ai ....Modelling the Transient Effects in Dense Phase Gas-Solids Flow in Pipelines. Almost every physical item we use in our daily lives at some point requires the transport and handling of powdered or granular materials during the manufacturing process. Be it food (sugar, flour), chemicals (soap powders, detergents), cosmetics (talc, face powder) or electricity generation (coal and ash); each of these industries uses the flexibility of pipeline systems to transport powders and granular solids using air as the motive force. However, the cost of poor design and the inaccurate prediction of system performance adversely affect the efficiency of many industries. Improvements to the accuracy of gas-solid flow modeling particularly for low velocity dense phase systems will have a direct impact on manufacturing efficiency.Read moreRead less
Unusual trisulfide chemistry. This project aims to investigate the mechanism of an unexpected reaction of trisulfides with common amide-containing solvents. Specifically, these solvents (such as dimethylformamide) were discovered to cleave S-S bonds in trisulfides and related polysulfides. This project expects to generate new knowledge in the understanding of the reaction mechanism and then use that understanding for useful chemistry. Expected outcomes of this project include a mechanistic under ....Unusual trisulfide chemistry.

This project expects to generate new knowledge in the understanding of the reaction mechanism and then use that understanding for useful chemistry. Expected outcomes of this project include a mechanistic understanding of a new reaction, and the use of this chemistry in polymer synthesis and polymer recycling. This project should provide significant benefits in new knowledge, as well as support new strategies in polymer synthesis and recycling to benefit the environment.Read moreRead less

Thermostamped carbon fiber/thermoplastic composite prototypes will be used to verify the sizing. In order to demonstrate industrial viability, recyclability and reprocessability analyses will be conducted. This sizing method can enable high-performance thermoplastic composites in nonaerospace applications with its atomistic level modelling and comprehensive characterisation routine. A key objective of this study is to produce sustainably manufactured composite materials that are also commercially relevant.Read moreRead less
Biomass-derived Carbon Dots Enable Flexible, On-Demand Hydrogen Delivery . Methanol is a promising liquid hydrogen carrier for long distance H2 transportation and exportation, because it is rich in hydrogen content, cheap, recyclable between methanol-formaldehyde and easier to manufacture from renewable resources including biomass waste. The critical bottleneck in adopting methanol as the carrier is the demanding dehydrogenation process. The project aims to create a new class of photocatalyst ba ....Biomass-derived Carbon Dots Enable Flexible, On-Demand Hydrogen Delivery . Methanol is a promising liquid hydrogen carrier for long distance H2 transportation and exportation, because it is rich in hydrogen content, cheap, recyclable between methanol-formaldehyde and easier to manufacture from renewable resources including biomass waste. The critical bottleneck in adopting methanol as the carrier is the demanding dehydrogenation process. The project aims to create a new class of photocatalyst based on biomass-derived carbon nanodots grown on transition metal (di)chalcogenide nanosheets that can effectively enable a light-controlled methanol H2 release of desired quantity. The key outcomes will be a new class of photocatalysts and flexible, on-demand hydrogen delivery technology for liquid hydrogen carriers.Read moreRead less
Sustainable Reversible Polymerisation. This project aims to address the problem of the current lack of efficient chemical recyclability of polymers. For the majority of polymers, no methods exist so far that are scalable and economic at the same time. To reach this aim, we will utilise a mixture of clever chemical concepts with continuous flow engineering.

This project aims to address the problem of the current lack of efficient chemical recyclability of polymers. For the majority of polymers, no methods exist so far that are scalable and economic at the same time. To reach this aim, we will utilise a mixture of clever chemical concepts with continuous flow engineering. This project expects to generate new knowledge in the area of depolymerisation and chemical recycling methods. The expected outcome of this project is a scalable process and its practical demonstration for full chemical recycling of various polymers used in everyday applications. This will provide a benefit to society as it allows to tackle plastic pollution problems, and creates avenues to green methods in plastic recycling.

This project is focused on understanding the interaction of cold atmospheric plasmas with biofilms, with the aim of biofilm eradication and ultimately offering an environmentally friendly alternative to current detergents and antibiotics. The research expects to elucidate the fundamental mechanisms of action for breakthrough plasma intervention technologies, which are sufficiently active to cope with the resistant nature of biofilms, yet are of low energy, do not adversely affect surface properties and critically leave no residual chemistry. This should provide significant benefits by delivering a new method to tackle the ubiquitous problem of biofilm contamination in food, water and medical areas.Read moreRead less
