De klanten van Tata Steel stellen steeds hogere eisen aan het productenpakket dat zij afnemen. Het product moet voldoen aan de productspecificaties en moet van zeer consistente kwaliteit zijn. Poeder dat gebruikt wordt om het continu gietproces mogelijk te maken, kan in de vloeibare toestand opgesloten …

Reversed-phase HPLC with mass spectrometric and diode array detection as well as some literature data were used to reveal the individual types of solutes in anthocyanin complexes of tulip flower petals that are responsible for tulip flower petals coloration of the samples available in the local flower …

A Quad Focus GridPix Gaseous Tracking Detector is under construction, to allow calibration and test beam measurements to validate the working principles of the (quad) GridPix detectors while using a focused electric field. The development is well on its way: both measurements should be able to be conducted …

The effect of an elevated sample temperature on the growth rate of carbon in the holes of a Multiple Aperture Array (MAA) has been examined. The loss of transmitted electrons through the MAA was measured by taking pictures with a camera of an Yttrium Aluminum Garnet (YAG) scintillation crystal. The growth …

This report outlines the origin of aberrations in a Low Energy Electron Microscope (LEEM) and how to measure and automatically correct them. The aberrations in a LEEM are mainly caused by the cathode objective lens and are a limiting factor for the achievable resolution. To optimise the resolution of …

The characteristics of a hydrogen plasma in an inductively coupled RF plasma setup were studied using a double Langmuir probe and an optical emission spectrometer. At various settings for the gas pressure, gas ow, RF power and probe position, values were obtained for the electron temperature and plasma …

Gas-oppervlakte interacties staan centraal in talrijke natuurlijke en industriële processen. Het begrijpen van deze interacties is belangrijk voor de ontwikkeling van diverse toepassingen. Dit interactieproces wordt sterk beïnvloed door de energie van de atomen / moleculen in het gas. Bij het instituut …

Nuclear fusion is seen as one of the future technologies for roducing electrical power. In a hot and con ned plasma deuterium and tritium will melt together and form a helium nucleus and a neutron. This process produces a total of 17.6 MeV energy. In the plasma instabilities occur. Suppression of these …

Synthetic fibers, mainly polyethylene terephthalate (PET), polyamide (PA), polyacrylonitrile (PAN) and polypropylene (PP), are the most widely used polymers in the textile industry. These fibers surpass the production of natural fibers with a market share of 54.4%. The advantages of these fibers are …

Seven new 1,3,5-cyclohexyltricarboxamide-phenylalanine derivatives were synthesized in order to investigate the effect of the amino acid chirality on the gelating properties of these small molecules in water. Gelation tests have shown that enantiomerically pure homochiral 1,3,5-cyclohexyltricarboxamide-L-phenylalanine …
