Research

Research at the JohnstonLab in Swansea University typically covers a number of diverse fields, but is primarily focussed on characterisation of structures using X-Ray Microtomography. The group has experience investigating many varied materials, from plant and biological specimens, to dense superalloys.

We have a focus on biomimetics and bioinspiration. Using X-Ray CT to investigate the hidden internal worlds of nature, and thinking about how and why these structures formed.  We then look for challenging engineering applications that could benefit from the inspiration gained from these natural architectures. Utilising 3D-printing, we can create rapid replicas or prototypes of previously hidden structures found via X-ray CT, demonstrated on an everyday object.

The group also researches aerospace materials, focussing on the destructive and non-destructive characterisation of abradable coatings, ceramic-matrix-composites, and nickel-based superalloys among others. Corrosion studies of zinc and steel alloys are also ongoing.

Also, the group has expertise in applying artificial intelligence to a number of areas including manufacturing, process optimisation, creep of metals, and sports performance.

Specific strengths in X-ray computed tomography have resulted in collaborations with glaciology, tephrochronology, regenerative medicine, Egyptology, corrosion scientists, and many others.

The underlying ethos behind work at JohnstonLab is that we are passionate about interdisciplinary and collaborative research; and the excitement and energy that working with researchers from very different fields can provide.

Current Research Projects include:

Nature’s Hidden Worlds – Investigating internal architectures within nature via X-ray microtomography. The aim is to consider the function of natural structures non-destructively, using 3-dimensional data to optimise the engineering and design of structures at varying length scales. Evolutionary optimisation, biomimetics, and bioinspiration leading to improved engineering. With PhD student Laura North @Loobags87

Abradable Coating Materials –  The aim of this research project is to study numerous mechanical characterisation technologies to further understand how abradable coatings behave. This data will also feed into a model that has been constructed to help predict abradable material life times in service. With PhD student Dan Moyle @DanMoyle8 and in collaboration with Rolls-Royce plc.

Gas Turbine Superalloys – The aim of this project is to develop optimum forming and heat treatment routes for selected casing and bolting alloys in gas turbines – in particular, ring rolling of Nickel-based superalloys. With EngD student Sam Gardner and in collaboration with Rolls-Royce plc.

Laser Ultrasonics – Investigating laser ultrasonics and their application to additive manufacturing. With PhD student Simon Garner and in partnership with TWI.

Imaging of Volcanic Debris/Tephrochronology – A collaborative project with Prof. Siwan Davies, Adam Griggs, and Dr Peter Abbott, investigating X-ray CT as a method of imaging volcanic deposits and networks in sub-sea core samples.

Ancient Egyptian Clay Cobra Figurines – Collaborative project with Dr Kasia Szpakowska investigating failure mechanisms in clay cobra figurines, relating fracture behaviour to human behaviour. A nice taster video

Using ‘digital’ Materials to Establish a Novel Investigative Platform for Cardiac Arrest – Collaborative project with Dr Peter Theobald (Cardiff Uni) to develop a realistic material heart model via additive layer manufacturing

Medical Device Optimisation – An industry collaboration with Dr Steve Brown (Haemair Ltd.), Dr Raoul van Loon (Swansea University) and Claudio Donofrio (PhD student) imaging device architecture and modelling bloodflow.

Providing new model organisms for biomedical research: The tale of molluscs, mice and men – Collaborative project with Dr Anwen Williams (Cardiff University) and Dr Andrew Davies (Bangor University) to investigate the feasibility of molluscs as new model organisms for bone.

Engagement & Outreach

We are eager to engage with publics, discussing science and engineering with broad groups. Richard has developed a number of outreach and engagement projects: #ResearchAsArt, Materials: Live!, and as a British Science Association Media Fellow at Nature.

#ResearchAsArt

Research as Art is a University-wide initiative that aims to develop the engagement skills of students and staff, fertilise cross-disciplinary collaboration, raise the profile of Swansea research and its researchers, and make the University a better place to study and work.The project provides a unique mechanism of accessible outreach for all research, displaying the important and far-reaching work, and also the human aspect and emotion of research that goes on at Swansea University to a diverse and new audience.

Submissions are visually striking artwork or images and accessible, engaging text – resulting in a truly unique initiative.

Engagement Image 1

This image won the Early Career Researcher award in Swansea University’s 2013 Research as Art competition. Engineer Matt Carnie explains that these solar cells from failed experiments represent a notion familiar in science – that “behind every success there are many times when things didn’t quite go according to plan".

Materials: Live!

Engagement Image 2

An innovative Swansea University outreach and engagement project, which introduces the wonder of materials science and engineering to entertain, enthuse and educate potential scientists and engineers of the future. Materials Live! forms a critical component of the “Materials Academy” at Swansea; a large project that delivers multi-level materials research and training.

  • Provide activities that enrich the Key Stages 1- 4 Science National Curriculum in addition to A/AS level curricula.
  • Encourage people to study STEM subjects related careers.
  • Engage with teachers and deliver CPD activities to enhance the materials science-related content in their lessons.

Materials Live! was founded in November 2012 to offer inspiration to young people in materials science and engineering and help build understanding of the opportunities in the sector in Wales. The initial phase allowed development and procurement of demonstrations for a range of materials including novel materials such as shape memory alloys, non-Newtonian fluids, aerogel and ferrofluids. 3D imaging facilities were established and talks, workshops and exhibitions devised. Themes of previous workshops have included; energy materials, aerospace materials, construction materials, biomaterials for health and wellbeing and marine materials – all delivered flexibly depending of the needs of the audience. 2nd round saw addition of tensile tester, dedicated FTIR and 3D printer, strain gauges and now a full outreach lab in Port Talbot, which can hopefully carry on with a legacy on the Bay Innovation campus. Stakeholder feedback resulted in expansion of the scope, including participation in CPD activities aimed at enthusing teachers to provide post-16 students with access to University facilities – giving them valuable new experiences and essential exposure to a University environment. The ultimate aim is to engage youngsters as early as possible with continued contact over a number of years, delivering fresh content at the appropriate level. This has been achieved by successful award of a second round of funding. The project also responds to a call from Welsh Government’s ‘science in Wales’ document for better collaboration and coherence between STEM providers in Wales by working with a large network of broader STEM partners.
