PhD Studentships available with Dr Alison Nordon at the Department of Pure & Applied Chemistry, University of Strathclyde, Glasgow

1. PhD studentship with FUJIFILM
Nanoscale polymer-stabilised pigment dispersions are one of FUJIFILM Imaging Colorants' development areas. Several of the properties of pigment/polymer dispersions are very process-dependent and difficult to measure, particularly at concentrations found in the process. Recent speculative work has shown that it is possible to detect the pigment in situ using spectroscopic methods and it is believed that information on concentration, particle size distribution and polymer behaviour is potentially obtainable. In this proposed project, a rigorous investigation of the influence of the different components in the system will be undertaken, initially looking at model systems and progressing to real process samples. The aim of the project will be to develop an understanding of the fundamental principles underlying in situ spectroscopic measurement in mixed polymer/pigment dispersions and to facilitate product development and manufacturing process control, leading to improved products.

2. EPSRC Industrial CASE PhD studentship with Bioinnovel
Recently, Bioinnovel has developed a novel ultrasound probe for on-line measurement of the rheological properties of biotechnology processes. This is highly challenging as biotechnology process broths often exhibit viscoelastic and/or non-Newtonian behaviour. Rheological (physical) information can either be used in isolation to assess the physiological state of the process or it can be combined with chemical information, such as nutrient and product concentrations, from on-line mid infrared (MIR) measurements. Hence, the information obtained from ultrasound and MIR spectrometry is complementary. However, the issue of how to analyse data from different sources in combination has yet to be adequately addressed. Therefore, this project will involve assessment of on-line rheology measurements in conjunction with development of strategies for combination of ultrasound and optical spectroscopic data to give enhanced understanding and optimisation of biotechnology processes.
