About the Project

The Centre for Doctoral Training in Aerosol Science (CAS) is inviting applications for a PhD research project at the University of Bath under the supervision of Dr Andrew Johnson

This project is ideally suited for students with an interest in both organometallic/inorganic synthesis and materials chemistry.

Inkjet printing is recognised as an efficient method for direct deposition of functional materials on flexible substrates in predesigned patterns, owing, in part to simple processing, low cost and adaptability for large-scale fabrication of electronic devices, sensors, light emitting diodes, etc. While inks used in inkjet printing have mostly consisted of organic polymers, metal nanoparticles and carbon materials such as graphene and carbon nanotubes, there is immense scope for the development of this methodology for the deposition of inorganic (i.e. metal oxide and metal chalcogenide) and inorganic/organic hybrid systems for energy harvesting applications.

Our vision is to develop and formulate new inorganic inks, containing inorganic compounds and/or nanoparticles, for the fabrication of either metal oxide (e.g. SnO, NiO or CuAlO2), metal chalcogenide (SnS, SnS2, Bi2Te3, MoS2) or metal oxide /chalcogenide/carbon nanostructured semiconducting components, for application in a range of devices in including solar cells, thermoelectric devices and flexible electronics. Core to the project is the use of aerosol assisted chemical vapour deposition, not only as a means of thin film fabrication but also as a mean of controlling crystallite size distribution and morphology.

EPSRC Centre for Doctoral Training in Aerosol Science (CAS):

CAS brings together a multi-disciplinary team of academics from 7 UK universities (Bath, Bristol, Cambridge, Hertfordshire, Imperial, Leeds and Manchester) spanning the physical, environmental and health sciences, and engineering.

Working with industrial and public-sector partners in the areas of healthcare, materials science, energy and transport, environment, consumer products and agrochemicals, we aim to tackle some of the most challenging problems in aerosol science.

Expertise in aerosol science is important in a broad range of disciplines spanning drug delivery to the lungs to the transmission of disease, climate change to combustion science, routes to novel materials to consumer and agricultural products.

Our graduates will become agile experts, able to work at the boundaries between the conventional disciplines where aerosols play a role.

Programme details:

The 4-year CAS training programme will include a period of intensive training in year 1, hosted by the CAS hub at the University of Bristol. You will receive comprehensive training in the core physical science of aerosols, research methods, an in professionalism and translation of research. You will then have the opportunity to build networks across the 7 universities, undertaking a short project at either your home institution or another partnering institution. These training elements will equip you for your PhD research in years 2-4, based at the University of Bath.

Throughout your PhD, you will be supported by a mentoring team of two academic supervisors and an industrial partner, who will host you for a placement in Year 2 or 3. You will benefit from the diverse backgrounds of your peers, with training in year 1 using team-based learning. Cooperative learning groups in subsequent years will continue to provide opportunities for peer-to-peer learning and support.

Funding Notes

CAS funding is for up to 4 years and is open to UK and EU applicants who have been ordinarily resident in the UK since September 2017.

A studentship will include UK/EU tuition fees, maintenance at the UKRI Doctoral Stipend rate (£15,009 in 2019/20, increased annually in line with the GDP inflator) and an allowance for research expenses, training and conference attendance.
