Wood

Bring nature into your home with wood! With knots – places where a side branch grew on the tree – and grains as an expression of the natural look, and the warm appearance of the material. Wood is a natural composite material, with cellulose fibres embedded in a matrix of lignin and hemicellulose – all […]

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 […]

Hydrogen

Just like coal, oil, natural gas and electricity, hydrogen is also an energy carrier – it contains energy that can be released, for example through combustion. Hydrogen has a high energy density of around 33 kWh per kilogram, almost three times the value of petrol. In practice, however, this high value is rather disappointing because […]

Carbon dioxide and global warming

The comfortable temperature on earth is due to the unique combination of the distance to the sun and the presence of our atmosphere. As a result, the earth absorbs just the right amount of solar energy we need for life as we know it. And the atmosphere acts as an insulating blanket, keeping the temperature […]

Nuclear energy

Nuclear power plants for energy generation use solid 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 barium and krypton. […]

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 […]
