Are you passionate about atmospheric physics, aerosol science, and particle generation? This exciting opportunity may be for you. The Engineering and Physical Sciences Research Council (EPSRC) Aerosol Centre for Doctoral Training (CDT), led by Bristol University, is seeking motivated individuals to join a pioneering four-year PhD research project focused on developing cutting-edge technologies for particle generation and calibration. Open to all applicants, this fully funded project offers the chance to contribute to groundbreaking research while receiving a generous, tax-free stipend at the UKRI rate (£19,237 for 2024/25).

Project Overview: Transforming Silver Particle Generators into National Calibration Standards

The core aim of this project is to transform a commercial Silver Particle Generator (SPG) into a state-of-the-art national calibration facility for the UK. The SPG is an innovative particle generation system specifically designed for producing ultrafine particles with modal diameters ranging from 2 nm to 80 nm. It promises exceptional stability and reproducibility, making it an ideal tool for particle number and mass calibration.

The scope of this project extends beyond silver particles. The research will investigate the possibility of adapting the SPG to generate particles from various other solid materials, making it a versatile, multi-source instrument. This transformation requires a comprehensive understanding of different particle characteristics, such as shape, mean diameters, and effective densities. The ultimate goal is to develop a calibration tool that meets international ISO standards, positioning the SPG as a vital resource in the field of aerosol science.

This project fits within the EPSRC’s strategic priority of ‘Frontiers in Engineering and Technology’ and aligns with the ‘Physical Sciences’ theme. It represents an exceptional opportunity for a talented student to engage in cutting-edge research with significant real-world applications.

Key Research Objectives:

1. Developing the SPG for Broader Material Use:
   The first phase of the project involves adapting the SPG for use with materials beyond silver, effectively turning it into a multi-source particle generator. This will require the successful candidate to characterise various materials, examining key properties like particle size distribution, shape, and effective density. This work is crucial for ensuring the new materials are suitable for use in calibration standards and meet the rigorous demands of ISO certifications.

2. Understanding Particle Behaviour:
   A key challenge in particle generation is understanding the behaviour of ultrafine particles during transport and storage. The student will use modelling techniques to predict and analyse particle losses during transportation, developing solutions to minimise these losses. This phase will involve advanced computational simulations and experimental validation, making it a comprehensive learning experience in particle dynamics.

3. ISO Certification and Calibration Facility Development:
   An essential aspect of this project involves turning the SPG into a national calibration facility in partnership with the UK’s National Physical Laboratory (NPL). The candidate will be responsible for ensuring that the facility meets all ISO standards, working closely with experts at NPL to understand the requirements and challenges involved in certification. This is an exciting opportunity to engage with both the technical and regulatory aspects of particle generation, gaining a deep understanding of the standards that underpin global calibration practices.

4. Collaboration with Industry Partners:
   In addition to academic research, this project involves significant collaboration with industry partners, particularly Catalytic Instruments (CI), a German company that developed the SPG. The student will spend time at CI’s facilities in Germany, receiving hands-on training in the programming and operation of the SPG. This experience will be invaluable in understanding how the instrument can be improved for broader use and commercialisation.

5. Commercialising Particle Generation Technology:
   One of the long-term goals of this research is to explore the commercial opportunities of the enhanced SPG. By working closely with both NPL and CI, the student will have the opportunity to contribute to the development of a commercial calibration service. This will involve technical innovation, business development, and engagement with potential customers and stakeholders, offering a well-rounded research experience that includes a focus on real-world applications.

The Research Environment: A Collaborative, Multi-Disciplinary Approach

This PhD project offers a highly collaborative research environment. The students will be based primarily at the University of Manchester, where they will develop the necessary skills to work with the SPG. Manchester is renowned for its research in atmospheric physics, aerosol science, and particle technology, offering an excellent foundation for this project.

Beyond Manchester, the student will spend considerable time working at NPL, located in Teddington, UK. NPL is a world-leading centre of excellence in measurement science, and the student will have access to cutting-edge facilities and expertise. This collaboration will transform the SPG into a national calibration standard.

Additionally, the student will benefit from international experience by working with Catalytic Instruments in Germany. CI is a pioneer in developing advanced aerosol instrumentation, and this partnership will provide the student with hands-on experience in the commercial sector, learning directly from industry experts.

Training and Development: A Comprehensive Doctoral Programme

The EPSRC Aerosol CDT offers a robust training programme designed to equip students with the skills and knowledge necessary to excel in aerosol science. In addition to the technical and experimental training provided by the project, students will participate in a wide range of training activities, including:

• Advanced Scientific Training:
  Courses in aerosol science, particle technology, and atmospheric physics will provide a strong theoretical foundation for the research.

• Modelling and Simulation:
  The project will involve the use of computational tools to model particle transport and loss mechanisms. Training in these techniques will be provided as part of the CDT’s broader curriculum.

• Professional Skills Development:
  The CDT programme emphasises the development of professional skills, including project management, communication, and collaboration. These skills will be essential for working effectively with partners like NPL and CI.

• Industry Engagement:
  The opportunity to work with Catalytic Instruments and develop a commercially viable calibration facility will provide the student with valuable insights into the intersection of science and industry.

Eligibility Criteria:

To be eligible for this project, applicants should have (or expect to achieve) at least a 2.1 honours degree or a Master’s (or international equivalent) in a relevant physical science or engineering discipline. Candidates with backgrounds in fields such as aerosol science, atmospheric physics, mechanical engineering, or materials science are particularly encouraged to apply.

While prior experience in aerosol science or particle technology is advantageous, it is not a strict requirement. The most important qualification is a strong interest in the research area and a willingness to engage with both the scientific and technical challenges of the project.

Funding and Benefits:

This four-year PhD project is fully funded, with tuition fees covered for both UK and international students. In addition to fee coverage, successful applicants will receive a tax-free stipend set at the UKRI rate, which for the 2024/25 academic year is £19,237. This stipend is intended to support students throughout their studies, allowing them to focus fully on their research.

How to Apply:

Before submitting an application, interested candidates are encouraged to contact Dr Paul Williams at the University of Manchester (paul.i.williams@manchester.ac.uk) to discuss the project in more detail. This will allow potential applicants to better understand the research aims, the work environment, and the application process.
