Dispersion is a critical process within the extrusion industry. The attention of this study is drawn to the deficiency in dispersive mixing quality in single screw extruders compared to their twin screw counterparts. This study outlines an approach that is used to evaluate and quantify the quality of …

In this TechForFuture project ‘Polymer Mixing in a Single Screw Extruder’ a method to optimize mixing elements is developed based on numerical simulations (Computational Fluid Dynamics, CFD). A numerical procedure is developed to calculate the flow field in the extruder. By tracing particles in this …

Limestone is a sedimentary rock that is composed mostly of calcium carbonate (CaCO3). Limestone is, among many applications, used as a raw material for the manufacture of quicklime. When limestone is heated, the stone calcinates and quicklime is formed. The primary use of quicklime is in the steel and …

In this research several methods were developed and validated using the Supermini 200 wavelength dispersive X-ray fluorescence spectrometer. A multielement was calibrated containing 26 elements and corrected for interference according to the de Jongh algorithm. The limits of detection and quantification …

Het Mauritshuis doet momenteel onderzoek naar de pigmenten en laagopbouw in verfmonsters uit kunst van Jan Steen en Giovanni Antonio Pellegrini. Hierbij wordt met Shell Nederland BV samengewerkt onder het Partners in Science project. Een onderdeel van dit project is een onderzoek naar het blauwe pigment …

Het aantonen of corrosie gedetecteerd kan worden in de omtrek richting van pijpleidingen. Er wordt gebruik gemaakt van zeer dispersieve akoestische plaatgolven genaamd Lamb waves. Als transducers worden er Elektro-Magnetische Akoestische Transducers gebruikt. Corrosion inside pipelines caused by salt …
