The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

On Thursday 16 November 2017 Thomas Leclerc defended his PhD Dissertation ‘A Corrective Approach to Reduce Aircraft Greenhouse Gas Emissions. Contribution to the Study of Interactions between Legal Orders of International Law’. The Supervisors are Professor P. Mendes de Leon and Professor L. Grard.

Transcutaneous vagus nerve stimulation (tVNS) was tested in chronic worriers. tVNS may reduce spontaneously occurring negative thought intrusions. After a worry induction, there was no longer an effect of tVNS. tVNS did not affect physiological responding to worrying.

Low-carbon (LE) technologies have a significant potential to reduce the total carbon emissions in China.

The use of N fertilizers has increased worldwide in the past century. While this increased input of N has increased food productivity, it has also contributed to decreases in biodiversity, soil quality and environmental health, including increases in greenhouse gas emissions.

Vinasse is a major by-product generated by the sugarcane biofuel industry. It is a source of microbes, nutrients and organic matter and often it is recycled as fertilizer.

Has the industrial sector in China effectively been decarbonizing in recent years, across different regions and subsectors, and is it plausible that it will reduce its CO2 emissions in conformity with national and internationally pledged emission goals?

This thesis studied in depth the energy use and CO2 emissions of the industrial sector in China.

The emissions of the Chinese industrial sector alone comprise 24.1% of global emissions (7.8 GtCyr−1 in 2015). This makes Chinese industrial emissions of unique national and international relevance in climate policy. This study reports a literature survey that quantitatively describes the evolution…

On Thursday 16 November 2017 Thomas Leclerc will defend his PhD Dissertation ‘A Corrective Approach to Reduce Aircraft Greenhouse Gas Emissions. Contribution to the Study of Interactions between Legal Orders of International Law’. The defence will commence at 13.45 hrs, at the Academy Building of Leiden…

Circular agriculture and more nature are important to reduce harmful emissions and to give a new impetus to biodiversity. But is that compatible with the Netherlands' position as an important exporter of food products? Professor of Conservation Biology Geert de Snoo believes it is, at least provided…

A new study from Leiden researchers shows that the carbon emissions of building materials are set to grow if we do not act rapidly. Even with known interventions implemented in concert, these emissions are much larger than the remaining 1.5 degree budget for building materials at today’s share, the…

Cutting down global emissions of greenhouse gases to combat global warming won’t do the trick alone: we also need negative-emissions technology that can capture carbon dioxide directly out of the air. In the prestigious journal Global Environmental Change, PhD candidate Oscar Rueda and colleagues shed…

The van Exter group has an extensive history of prior research in classical and quantum optics. As former part of the group of Han Woerdman, we have studied topics as diverse as:

The formation and evolution of galaxies is fundamentally driven by the formation of new stars out of cold gas.

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

This thesis presents pioneering work on the panchromatic emission of some of the most luminous galaxies in the early Universe: star forming galaxies and active galactic nuclei.

Examining if large scale application of new energy pathways can be constrained by materials and emissions.

A substance flow analysis, covering about 99 % of the flows of chlorinated substances in the Netherlands.

The 2015 Dissertation Prize of the Global Neutrino Network has been awarded to Tri Astraatmadja, who was part of the Leiden/Nikhef ANTARES group during his PhD research. Astraatmadja receives the award for his thesis 'Starlight between the waves: In search of TeV photon emission from Gamma-Ray Bursts…

Research in the Daniela Kraft Lab focuses on self-assembly in biological and soft matter systems, ranging from anisotropic colloidal particles to lipid membranes, emulsions, and viruses.

The aim of this project was to estimate emissions from lead products-in-use for the past, the present and the future and assess the development of toxicological risks associated with these products.

An overview is given of the flows of chlorine and chlorinated hydrocarbons through the Europian Union.
