The Low Frequency Array enables studies of low-frequency carbon radio recombination lines with unprecedented sensitivity, spectral and spatial resolution.

Bicarbonate buffer is largely found in nature due to its ability to regulate pH variations around neutral values. As the pH changes, so does the speciation of the buffer.

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.

Loneliness and social isolation have become a significant problem in contemporary Japan. The financial burden associated with an ageing population has severely constrained the ability of local authorities to address the problem. As a result, policymakers have sought cost‐effective methods of tackling…

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.

This thesis focuses on protoplanetary disks: flattened structures of gas and dust around young stars in which planets are expected to form and grow.

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…

We have conducted a full spectral line survey of the 3-13 micron region of two massive protostars, AFGL 2591 and AFGL 2136, for the first time at high spectral resolution.

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.

Vast, often populated, areas in dryland ecosystems face the dangers of desertification.

This article on private active cyber defense by Dennis Broeders is part of a special issue of the Journal of Cybersecurity, based on a selection of contributions taken from the 2019 Conference on Cyber Norms organized by The Hague Program for Cyber Norms.

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

The parliamentary elections in the Netherlands, scheduled for March 2017, are likely to result in a fragmented parliament and a complicated coalition formation process, according to Dutch political scientist Hans Vollaard (Leiden University).

Vedran Dunjko (LIACS and applied Quantum algorithms (aQa) Leiden) and Tomoyuki Morimae (Kyoto University) are to collaborate with Qu&Co. Qu&Co is a leading European developer of quantum software.

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…

How can we increase the openness and reproducibility of quantitative research? This was the central theme of a workshop on openness and reproducibility, organised by the Center for Open Science (COS) on 2 November 2016.

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…

Stellar feedback is a crucial ingredient in the evolution of galaxies.

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.
