The main question I want to answer is about the mutual influence between the cultural and settlements changes that occurred between the Bronze and the Early Iron Age in Margiana and the management of water resources.

Both Leon Jacobse and Thom Hersbach from Marc Koper's research group obtained their PhDs cum laude. They both investigated changes on the surface of a platinum electrode. Jacobse studied this at a positive voltage, Hersbach at a negative voltage. Platinum has the potential to convert renewable energy…

Plants, algae and cyanobacteria have the amazing capacity to perform delicate photophysical and photochemical processes of light capture, excitation transfer, charge separation and catalysis in fluctuating living environments. As a consequence, photosynthetic proteins and membranes form dynamic architectures.…

CML report 192

Decentralized plug and play systems for energy production are the future picture of our society. Artificial photosynthetic systems are used for this purpose.

Huub de Groot is professor in Biophysical Organic Chemistry. With his team he works in the field of photosynthesis and artificial photosynthesis. The molecular basis for photosynthesis is formed by protein complexes and organelles that contain chlorophyll molecules. The antenna systems herein capture…

Consequences for sediment stability and seston trapping

We report new computational and experimental evidence of an efficient and astrochemically relevant formation route to formaldehyde (H2CO). This simplest carbonylic compound is central to the formation of complex organics in cold interstellar clouds and is generally regarded to be formed by the hydrogenation…

In order to analyze the challenges linked to data use in the context of nexus governance, Giest & Mukherjee use a policy design lens and more specifically the perspective of organizational policy instruments to look at the Mediterranean region.

Using a clever experiment, PhD candidate Shengxiang Yang discovered how gold electrodes convert water into oxygen. He is the first to unravel the mechanism of this reaction. Yang published his results in the journal ACS Catalysis.

Warisa started as a Postdoc researcher at the Department of Environmental Biology of CML in March 2020.

Coordination chemistry is the chemistry of metal atoms

Training a robot in a real-life environment is more or less impossible. Computer scientist and psychologist Roy de Kleijn switched to training in a simulated, virtual one instead. ‘You do have a reality gap, but the more precisely you train the robot, the better it is in practice.’ His inspiration:…

“A partnership based on water” summarised Gerhard van den Top the relationship between the Netherlands and the Philippines in the 4th Louwes Lecture. He emphasised the significant role of international and intercultural cooperation in managing the complex challenges brought forward by climate change.…

Archaeologist Araceli Rojas has been invited to participate in the award-winning festival Let’s Talk about Water. This festival combines academic seminars, movies, and panel discussions around water issues around the globe.

Leiden astronomers and ecologists are developing an instrument that lets people measure the quality of surface water with a smartphone.This international citizen science project, MONOCLE, is a collaboration between scientists and local people in Tanzania, Brazil and four European countries.

A small project grant from the Gerda Henkel Stiftung foundation has been awarded to Dr. Andrea Waters-Rist, a co-applicant on a project entitled

Interview in the popular journal for the agricultural sector Nieuwe Oogst with CML-researcher Martina Vijver about the Dutch policy on pesticides and it’s possible conflicts with the aims for clear surface and groundwater.

This thesis presents the results of a study on the interfaces of insulating oxides with and without the insertion of a magnetic layer.

In this Thesis, novel charge induction mechanisms of ionic liquids are treated, tested and experimented on complex oxides, in particular cuprates.

The Water Resources and River Management course (300-level) took a day long field trip to exotic… South Holland! Here students were able to examine a variety of ways in which densely populated deltas confront issues related to water management and flooding, from a Dutch perspective.

It may well be possible to remove nitrate from polluted groundwater and at the same time produce ammonia in a sustainable way, according to PhD candidate Phebe van Langevelde and Professor Marc Koper of the Leiden Institute of Chemistry in Joule on 26 January. Together with a German colleague, they…

The Fine Mechanical Department's (FMD) new Wardjet A0612 will cut anything using a 4000 bar water jet. This enables the FMD to work faster, more accurately, and to perform more versatile jobs.

Dutch book about pesticides and waterquality

It may not seem necessary to install special tap water stations in University buildings, but it is very useful: every tap here also means a tap in a developing country. With the the 35 tap water stations that Leiden University installs, the slum area of Madoya in Nairobi will soon have clean drinking…

Paul Hudson, Associate Professor of Physical Geography at Leiden University College, examines human impacts on lowland rivers in his new book.

Leiden University will install over 30 tap water stations in the autumn of 2017 at the various University buildings. The first is already in use.

The local ordering of atoms at the surface of a metallic particle determines its catalytic activity and selectivity. As energy systems of the future will be based on efficient catalytic conversion of small molecules in closed cycles, we study how structural effects of catalysts can be used to our ad…

Science Magazine has published three back-to-back papers on an important discovery in solid state physics. Leiden physicist Jan Zaanen wrote a Perspective article on the subject in the same issue of 4 March.

A group of ten Indonesian scholars, NGO-members, and state officials coming from the Indonesian Ministry of Environment and Forestry visited their Dutch colleagues, academic and practical experts, to discuss issues related to water management and environmental regulation .

The Real Estate of Leiden University has done a fantastic job at placing new water tap points at several new locations! Have you spotted the new ones within your faculty? We wish you a happy hydrated day!

Scientists have long been puzzled why it is easier to produce hydrogen from water in an acidic environment than in an alkaline environment. Marc Koper comes with an explanation: the reason is the electric field at the surface of the catalyst, which is larger in an alkaline environment, as he writes…

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.

From treatment plants to hot showers, emissions from water use in the U.S. are equal to 50 million cars driving around for a year.
