Time frequency analysis techniques in terahertz pulsed imaging
Terahertz (THz) radiation is abundant in the natural world yet very hard to harness in the laboratory. Forming the boundary between `radio' and `light', the so called "terahertz gap" results from the failure of optical techniques to operate below a few hundred terahertz, and likewise the failure of …

Activation of Release by Hydration in Pharmaceutical Tablets Studied by Terahertz Pulsed Imaging
… in activating the drug release. In this thesis, terahertz pulsed imaging (TPI) was used to investigate the hydration kinetics of pharmaceutical tablets in a one-dimensional liquid penetration setup. The capability of terahertz pulses to probe through, and respond to, interfaces of different …

Predictive Disintegration Process Modelling of Immediate Release Tablets Using Terahertz Technology
… a predictive and mechanistic framework based on terahertz (THz) characterisation and physics-informed modelling. This model aims to reduce reliance on labour-intensive, large-scale DoE within PAT and QbD frameworks, thereby saving resources and minimising chemical waste. Terahertz Pulsed Imaging …

Terahertz Methods for Investigating the Liquid Transport Characteristics in Porous Media
… and heterogenous catalysis. In this thesis, the terahertz methods, i.e. terahertz time-domain spectroscopy (THz-TDS) and terahertz pulsed imaging (TPI), were used as promising techniques to quantify the impact of the microstructure characteristics and formulation on the liquid transport process …

Investigating the Hydration and Disintegration Mechanisms of Film-Coated Pharmaceutical Tablets
… and disintegration processes were studied using terahertz pulsed imaging (TPI), while optical coherence tomography (OCT) was used to capture further details on the swelling process of the polymer and the interfacial changes during the hydration of film-coated tablet. To generalise the …
