Handling long-range Coulombic interactions in Fortran molecular dynamic simulations via Ewald summation

Betase’s Eddy Brinkman first came into contact with the Fortran programming language in the early 1990s, during his graduation work in Chemical Engineering at the University of Twente in Enschede, The Netherlands. Researchers within the Department of Chemical Physics used the computer simulation package GROMOS (Groningen Molecular Simulation), among other things, to perform molecular dynamics … Continue reading Handling long-range Coulombic interactions in Fortran molecular dynamic simulations via Ewald summation

50 years of membrane research in Twente

Twente has always been a pioneer in membrane technology. About 50 years ago, with the arrival of Kees Smolders, research on membranes started at the Technische Hogeschool Twente, later University of Twente. And some 10 years later, Ton Burggraaf and his group started developing ceramic membranes. The history book ’50 years of membrane research in … Continue reading 50 years of membrane research in Twente

Structure determination with X-ray diffraction

X-ray diffraction (XRD) is an analysis technique to determine the crystal structure of crystalline materials. You do this by bombarding the material with X-rays. This is radiation with a wavelength of about 1 Angstrom (10-10 m), in the same order of magnitude as the distance between atoms in a crystal. Where a normal mirror reflects … Continue reading Structure determination with X-ray diffraction

Electrochemistry

Electrochemistry occurs – how could it be otherwise – at the interface between electricity and chemistry. Consider phenomena that occur when chemical reactions generate an electric current, or when you can use electricity to modify chemical compounds or materials. For example, chemical reactions in batteries and fuel cells generate electricity. Conversely, electrolysers allow hydrogen gas … Continue reading Electrochemistry

Computer chips – how are they made?

Just like in the ‘good old’ desktop computers, the heart of today’s multimedia devices such as notebooks, tablets and smartphones is made up of microprocessors. Such a microprocessor, also known as computer chip, processes data based on instructions. A microprocessor consists of a huge number of tiny switches called transistors, each of which has essentially … Continue reading Computer chips – how are they made?
