A few seconds before you receive a call or SMS message on your mobile phone, the speaker makes a buzzing noise. Is this clairvoyance of the speaker? No way. Here, the wire to the speaker … Continue reading Conductive polymer composites for electromagnetic shielding
What is the common denominator in inkjet printers, parking sensors for cars, gas lighters and ultrasound imaging for babies? The answer: all these applications make use of piezoelectric materials. This material has something special: it has the capability to change shape – for example become shorter or wider – by applying an electric voltage over … Continue reading The hidden use of piezo technology in applications all around us
Between 1 October 2009 and 30 September 2011, Betase participated in the European knowledge transfer project iPolyCond, together with other European partners and partly funded by the European Commission. The booklet iPolyCond conductive polymers as well as the book An introduction to conductive polymer composites are results of the project, aiming at developing training materials … Continue reading iPolyCond – European knowledge transfer project
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
