1. Process analytical methods for monitoring of the film coating on pharmaceutical pellets and tablets using NIR spectrometry and image analysis
Abstract : Pharmaceutical tablets and pellets are often covered with a coating. There is a need for methods that enable monitoring of the growth of such films during processing. Such analyses can be performed using process analytical chemical methods based on near infrared (NIR) diffuse reflectance spectrometry. It provides with analyses that take only ca. READ MORE

2. Quantitative microscopy of coating uniformity
Abstract : Print quality demands for coated papers are steadily growing, and achieving coating uniformity is crucial for high image sharpness, colour fidelity, and print uniformity. Coating uniformity may be divided into two scales: coating thickness uniformity and coating microstructure uniformity, the latter of which includes pigment, pore and binder distributions within the coating layer.

3. The Prediction of Fluid Flow, Particle In-Flight and Coating Characteristics in Atmospheric Plasma Spraying
Abstract : The aim of this thesis is to make a contribution to the development and application of models for the simulation and optimisation of plasma spray processes in production engineering. In particular, focus is placed on the development, combination and application of models for coating deposition and robot motion optimisation, the prediction of coating temperatures during deposit, the simulation of the plasma flow field, and in-flight characteristics of injected particles.
