Row Row Row your boat: A look at the history and materials used in high performance rowing boats
Rowing has come a long way, as one of the oldest sports in the world dating as far back as 4000BC, to London water taxis racing along the Thames in the 1900's through to the elite level of the modern Olympic games. Consequently, rowing equipment has seen some of the most dramatic changes in materials composition, development, testing and modelling as any sport or industry in modern times.
From master carpenters constructing long ships through to the first composite boats made from papier-mâché in 1870 and beyond into the high-performance aerospace grade composites and metals used in modern racing shells today. In a sport where medals are won and lost by millimetres, materials have played a crucial role, as athletes and manufacturers look to maximise performance.
This presentation will look at the past, present and future of rowing boat materials, the development of new manufacturing methods and how materials can make a boat the length of a bus carrying over 1 tonne of rowers weigh less than 100kg.

Challenges for Lithium-ion Batteries
Efforts to decarbonise infrastructure, to support policy changes and mitigate the increasing effects of climate change, is seeing a renaissance of fully electric vehicles and hence a future which relies heavily on Li-ion battery technology. With the increasing demand on supply, the limitation on this transition will rely on the use of several critical materials, one of which is the technology’s namesake: lithium. The majority of the world’s supply is limited to four countries, and thus to secure a green transition in the UK, in an environmentally sensitive way we need to consider lithium recovery from both primary and secondary resources, and work towards a circular economy. In this talk I will provide an introduction to this technology, before considering the challenges and methodology suitable for both primary (geothermal waters) and secondary (recycling) resources, while highlighting the active role of collaboration and engagement.

Working with Neutrons: Identification of Local Hydrogen Concentration in steels in seawater environment using Neutron Imaging
Hydrogen diffusion and subsequent embrittlement result in the failure of the pipelines. An understanding of the relationship between the hydrogen concentration in the steel with the crack initiation and propagation is important. Moreover, correlation of crack growth rate with total hydrogen content would require the investigation and imaging of the hydrogen distribution at crack tips, pits, and crevices. In order to correlate fatigue crack growth rate with total hydrogen content at the crack tip, a method to determine the hydrogen distribution at crack tips is required. The ability of neutrons to penetrate metal and identify light elements like hydrogen is exploited using neutron imaging, a non-destructive method, establishing sensitivity. The aim of current project is to evaluate local H content for better identification of embrittlement ensuring better H transportation and storage.
