Materials for red wine

Subtle or robust? Wine is an interplay of the type of grapes, the soil, the climate, the time of picking and the craftmanship of winemaking. During the winemaking process, the many components of the grapes are transferred into the wine, and yeasts take care of the conversion of sugars from the grapes into ethanol. As […]

Book Meet materials has been published – in English!

About five years ago the Dutch book Kennismaken met materialen saw the light of day. A book that has found its way into large and small companies, educational and research institutes, universities, bookstores and libraries, as a reference work but also as a (business) gift for many interested parties. The described examples in the world […]

Nuclear energy

Nuclear power plants for energy generation use the solid ceramic material uranium oxide UO2 as “fuel”. If the uranium isotope 235U in the nuclear reactor is bombarded with slow neutrons, this produces an unstable uranium isotope 236U that very quickly decomposes into large nuclei with a mass number around 142 and around 92, such as […]

Electrochemistry of the fuel cell

In an internal combustion engine in your car, the fuel – petrol, diesel, LPG – reacts directly with oxygen. The larger volume of combustion gases pushes a piston back and forth, and a crankshaft converts this back-and-forth movement into a rotating movement for the car wheels. Chemical energy from the fuel is converted into useful […]

Impedance spectroscopy: monitoring of electrochemical processes

If you want to measure the corrosion progress or the performance of a fuel cell, impedance spectroscopy is a suitable technique. This allows you, for example, to monitor processes within electrochemistry such as corrosion over time by taking measurements at regular intervals. Materials science meets electrical engineering. Suppose you are an electrician and you want […]

Laser: social medium avant la lettre

Lasers are everywhere around us, and are indispensable in our daily lives in applications such as metal cutting and welding, in DVD players and laser printers, to send signals through glass fibers, or to sinter particles to each other in 3D printing manufacturing processes. And where would science fiction movies like Star Wars be without […]

Electrochemistry behind rechargeable lithium ion batteries

Batteries exist by the grace of people who want to be mobile at all times. Lithium ion batteries are especially popular because of their high energy density – up to 200 Watts of energy per kilogram of battery. But also because they can be recharged over and over again without deteriorating significantly. And that’s why […]
