Development and physical characterisation of polyethylene glycol glycerides-based gel formulations for macromolecule delivery
… for protein/peptide delivery. A thorough physical and mechanical characterisation of the gels (with and without lysozyme as a model protein) was conducted using a combination of analytical techniques including ATR-FTIR, DSC, relaxometry NMR, rheological and texture analyser, and imaging …

The chemical and physical characterisation of illicit tablets and development of a statistical model to identify populations within the illegal supply chain
… of illicit tablets seized from the Tayside area. Physical and chemical analysis was compared with known pharmaceutical tablets and resulting data was statistically evaluated, to reveal potential links between illicit cases and distinguish pharmaceutically manufactured diverted …

Production and characterisation of nanoparticulate silicon photovoltaic devices
… through the device. Results from the electrical characterisation show that the printed devices exhibit electrical properties characteristic of silicon PV devices, confirming that the experimental process followed resulted in the successful production of a functional silicon solar cell. This …

Fused deposition modelling three-dimensional printing of solid dosage forms
… for FDM-3DP. Rheological, mechanical and physical characterisation of filaments were evaluated to provide information on the impact of these properties on the FDM 3DP process. Theophylline-loaded filaments, suitable for FDM-3DP, were successfully formulated using three polymeric carriers …

Development of Methods to Predict and Enhance the Physical Stability of Hot Melt Extruded Solid Dispersions
… because of their meta-stable nature, the physical stability of amorphous solid dispersions has been considered to be the main obstacle for their formulation development and commercialisation by the pharmaceutical industry. The aim of this project was to understand, predict and enhance the …

Targeting the p53/MDM2 protein-protein interaction
… we describe the synthesis, molecular modelling, physical characterisation and biological testing of novel inhibitors of the p53/MDM2 protein-protein interaction based on the natural product chlorofusin. The first focus is a combinatorial library generated in the Searcey laboratory of known …

Influence of particle size and morphology of Pt₃Co/C on the oxygen reduction reaction
… catalysts were analysed using electrochemical characterisation techniques such as cyclic voltammetry, CO stripping voltammetry, rotating disk electrode and rotating ring disk electrode. Physical characterisation of the catalysts was also implemented. The techniques used were x-ray diffraction, …

Performance and properties of structural concrete made with corex slag
… slag replacement levels between 30 and 70%. The physical characterisation of corex slag revealed that the material is finer than blastfurnace slag, having more ultra-fine particles. The oxide analysis showed that the higher proportions of the calcium and magnesium oxides present in corex slag …

Oxygen reduction reaction on carbon supported dispersed platinum nanoparticles and extended platinum surfaces
… agglomeration with platinum loading, and physical characterisation methods such as TEM and XRD showed an increase in the average particle size with increasing platinum loading, which supports the CO stripping voltammetry findings. The findings indicate a profound dependence of the ORR on …
