Perfect for designing new molecules
Even a small quantum computer should be able to simulate exactly the properties and behaviour of new molecules. This would take chemistry to an entirely new level. Better solar panels, more powerful batteries, saving lots of energy in the chemical industry: the applications have the potential to transform…

Substances from Cradle to Grave
Materials balances have been used in the recent past for the analysis of substance oriented environmental problems and the formulation of measures for environmental policy. In this study an integrated tool, based on the materials balance principle, has been developed for the analysis of both environmental…

Hominin Evolution in Africa
The Great Rift Valley in Africa is a real treasure trove for discovering early human fossils. The fossils found in this part of Africa have determined our view of human evolution. But was the Great Rift Valley really the place where evolution took place or just a place where fossils are well preserved…

Iron Age Echoes
D. Fontijn, Quentin Bourgeois & Arjan Louwen (eds) (2012). This publication describes the history of “barrow landscape” near Echoput in Apeldoorn. Two burial mounds were examined and it became clear that our prehistoric predecessors carefully managed and maintained the open area for a long time, before…

Bridging the gap between physics and chemistry in early stages of star formation
A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.

Lessons from the Bronze Age: ‘In order to achieve something, you have to give something up.’
Professor David Fontijn is fascinated by the question why people destroy objects that are dear to them. It is a phenomenon that you find everywhere in the world, gaining particular strength in the European Bronze Age. Fontijn wrote a book on this ‘economy of destruction’, published by Routledge.
