PAC, short for porous asphalt concrete, is a popular type of asphalt as top layer or wearing course for motorways in The Netherlands. Less hydroplaning, less trouble due to splashing water and also less sound of vehicles roaring over it. All because the material is porous: coarse granulate ‘glued’ to each other by a small … Continue reading Self healing in road construction
This booklet gives a look behind the scenes of the research at Delft Centre for Materials (DCMat), at Delft University of Technology. Simply by relating images of the everyday life of Delft and surroundings to the fascinating world of technology, materials and research at DCMat that is hidden behind that ‘everyday life’. To expressly bring … Continue reading Delft in materials – Materials in Delft
After several years of development, researchers at the Universities of Twente and Amsterdam and the Energy research Centre of the Netherlands have succeeded in obtaining a membrane system which is hydrothermally stable under semi-industrial dehydrating conditions at elevated temperature. This organic-inorganic hybrid membrane system combines the best of both worlds: flexibility and water repelling properties … Continue reading Breakthrough in pervaporation membrane for dehydration of solvent streams
Betase invests in new technologies. This is illustrated by our participation in 2006 and 2007 in a project to demonstrate how small-scale (surface) water purification can be realised economically and technically using mobile, compact, robust ceramic membrane systems. In this project, partly funded by the Province of Fryslân, we cooperated with membrane manufacturer Hyflux CEPAration, … Continue reading Demonstration of innovative water purification system
This article presents the state of the art (2005) of ceramic membranes for gas separation, particularly for the separation of hydrogen from process streams. It includes an overview of recent literature and reveals the best types of membranes for hydrogen separation, with their strong and weak points as well as key players based on patent positions. … Continue reading Ceramic membranes for gas separation – Recent developments and state of the art
Modern analysis instruments provide a deluge of measurement data. Automatic data processing is necessary to obtain relevant information. But: what is smart software that filters the data stream on important information and how can this properly be visualised? A short course in data reduction for the laboratory. Many analysis techniques in the chemical laboratory have … Continue reading Data reduction: between measuring and knowing
