Polymer nanoparticles with gradient morphology for environmentally friendly aqueous coatings applications. The commercial and practical importance of coatings (paints) in today’s society can hardly be overstated. With the ongoing drive towards more environmentally friendly coating systems, there is a strong desire to replace traditionally employed solvent-based coatings with entirely waterborne systems. Waterborne coatings are a key measure by which the coating industry can meet requirements to ....Polymer nanoparticles with gradient morphology for environmentally friendly aqueous coatings applications. The commercial and practical importance of coatings (paints) in today’s society can hardly be overstated. With the ongoing drive towards more environmentally friendly coating systems, there is a strong desire to replace traditionally employed solvent-based coatings with entirely waterborne systems. Waterborne coatings are a key measure by which the coating industry can meet requirements to reduce emission of volatile organic compounds. However, maximum performance cannot be achieved currently using waterborne coatings, which in turn limits applications. The overall aim of this project is to develop environmentally friendly high-performance waterborne coatings that will enable replacement of currently employed solvent-based systems.Read moreRead less
Tailoring composite propellers for reduced sound radiation. This project aims to explore the generation of noise by composite propellers and to use this understanding to tailor the composite properties to reduce underwater noise. Propellers are a harmful source of noise in the marine environment, disturbing animal behaviour, revealing the location of naval vessels and interfering with sonar operation. Adaptive composite propellers are potentially quieter than metal propellers, as well as offerin ....Tailoring composite propellers for reduced sound radiation. This project aims to explore the generation of noise by composite propellers and to use this understanding to tailor the composite properties to reduce underwater noise. Propellers are a harmful source of noise in the marine environment, disturbing animal behaviour, revealing the location of naval vessels and interfering with sonar operation. Adaptive composite propellers are potentially quieter than metal propellers, as well as offering improvements in efficiency and fuel consumption. The aims of this project are to understand the physical mechanisms associated with composite propeller noise generation. The outcomes are intended to provide advanced numerical capabilities that will support the development of quieter marine propeller designs to improve defence capability and the acoustic environment for marine mammals.Read moreRead less
