Abstract
The objectives of this PhD project are to address the challenges of in-situ TEM and introduce a new generation of in-situ TEM equipment. In Chapter 2 the in-situ TEM facilities are introduced, focusing on the nanoreactor that has gone through quite some development stages during this project. Several types of in-situ TEM nanoreactors were fabricated using Microelectromechanical Systems (MEMS) technology, which enables miniaturisation of the complete catalytic reactor (reactor column, heating system and gas system). The different generations of nanoreactors are the glued nanoreactor (GNR), the wafer bonded
