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…

Plants could be regarded as small chemical factories, which produce chemical substances via photosynthesis. If we can imitate photosynthesis in an artificial system, we can make clean fuels and materials out of sunlight and CO2. Huub de Groot is very close to designing a system of this kind.

The coal-power energy sector is using enormous amounts of fresh water which is projected to negatively affect lives and the ecological balance of the surrounding region. This is the conclusion of the new report The Unquenchable Thirst of Energy Production, published by Greenpeace Bulgaria and Leiden…

Every month a member of the Institute for History tells about a book that inspired him or her. Afterwards, the pen is passed on to another colleague. This month dr. Meike de Goede tells about the book 'Between Tides' by Valentin Mudimbe. The novel, little known beyond the circles of Africanists and…

How can child participation be defined, what is the importance of child participation and how can it be promoted?

PhD defence

Leiden physicists have developed a way to address how accurately a superconducting single photon detector (SSPD) can be characterized by detector tomography. SSPDs are not fully understood, and tomography is a key element to determine how these devices detect light. A better understanding of these detectors…
