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 […]

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 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 […]
