To be able to measure small forces or small deviations from Boltzmann, the external vibrations at the resonance frequency must be very low. To achieve this, we have developed a very soft vibration isolation system and combine it with several other measures to reduce vibrations in our dilution refrigerators.…

Kim Stroet is examining how the interaction between teachers and pupils influences pupils’ motivation. ‘Children need to have the feeling that they are in control of their own learning process.’

Electrolysis is a technique that can be used to convert CO2 into fuels and other useful products. To do this efficiently and on a large scale, however, we need to understand exactly how electrolysis works. Professor Marc Koper is an expert in this field.

Past objects offer a wealth of information about life in earlier times. Loe Jacobs is an expert in making earthenware objects, using the same methods and means used in earlier times.

In the summer of 2011, from June 14th until August 5th, the Laboratory for Human Osteoarchaeology conducted an excavation on the former cemetery of Middenbeemster in cooperation with archaeological company Hollandia.
