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

In this thesis, we study travelling waves in stochastic reaction-diffusion equations. We extend techniques from the deterministic theory for travelling waves to apply to the stochastic version, which allows us to compute the stochastic wave speed and shape, and draw conclusions on the stability of the…

A semi-empirical version of the specific reaction parameter approach to density functional theory (SRP-DFT) has been remarkably successful at predicting dissociative chemisorption probability vs. incidence energy curves for reactions on metal surfaces. New quantum Monte Carlo (QMC) calculations on the…

This thesis discusses the physical and chemical processes than influence the composition of forming planets.

Multicopper oxidase, laccase, can efficiently reduce oxygen to water and are mostly used in the enzymatic biofuel cells.

For Leiden University’s operations, sustainability is an important topic, especially looking at the CO2-footprint, renewable energy and the greening of buildings.

The development of new environmentally sound technologies is seen as a key route towards achieving sustainability.

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?

How is Young Star Renske Donkers doing now? Early this year she was the second person ever to win the Young Star Award for the best bachelor student. After her bachelor Molecular Science & Technology, Renske is now busy with her master Chemical Process Engineering in Delft. ‘This award was a great boost…

Part of our social contact is currently online, with no physical proximity. Does digitalisation mean that we are losing an effective way of making contact with one another? This is what Reinoud Kaldewaij will be studying with a Veni subsidy from the Dutch Research Council (NWO). 'An issue that will…

Several buildings need to be demolished to make way for phase 2.

Leiden University is working on a green, circular campus, with a significant reduction in energy consumption by 2050 as its goal, as elaborated in the Route Map Energy Transition Buildings, published in 2022.

The energy system is at the heart of two of the greatest challenges of the 21st century: decreasing CO2 emissions to meet the ambitions of the Paris agreement while fulfilling the growing energy demand associated with the economic aspirations of a growing world population.

If you could convert CO2 into building blocks for other molecules with the help of electricity, you could make the chemical industry considerably more sustainable. Leiden chemists have unravelled a fundamental part of this process and applied this knowledge in a real device, as they write in Nature…

Managing scarcity to serve the public interest is a classic government task. An important way to execute this task is by allocating individual rights that are only available in limited quantities, such as CO2 emission allowances, gambling licences, subsidies, radio frequencies, public contracts and…

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

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…

Fundamental understanding of molecular reactions on metal surfaces is important for improving heterogeneous catalysis.

PhD defence

From a meaningless block of plastic to an advanced component that contributes to the energy transition. The technicians and scientists of our faculty think it out in detail and make it a reality. This special project shows that they need each other.

This thesis describes the use of bioorthogonal proteins in immunological settings. It provides an introduction towards the field of protein modification, which was used throughout the thesis for the expression of proteins containing unnatural amino acids.

The following page offers tips for more sustainable travel options, such as taking the train or bus, and highlights online tools that can help you plan eco-friendly trips and find affordable tickets.

We simulate interstellar clouds with special plasma expansions and chemical reactions on icy dust grains to be measured in ultra-high vacuum setups. This provides the data necessary to guide and interpret astronomical observations and to model reaction networks in space. [Harold Linnartz]

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

The electrochemical oxygen reduction reaction (ORR) is an essential half-reaction for the utilization of hydrogen as a sustainable fuel, via the conversion of hydrogen to electrons and protons facilitated by the ORR. In the most common fuel cells, the ORR is requires high loadings of non-abundant platinum…

The mechanism of the electrochemical reduction of dioxygen by a mononuclear pyridylalkylamine copper complex was investigated (see picture). It was shown that in neutral aqueous solution dioxygen undergoes stepwise reduction, wherein hydrogen peroxide plays a key role. The rate constants determined…

Why do some children confront social challenges with confidence, whereas others experience difficulties? What is the role of child temperament and child emotional dispositions? What is the role of parenting? This project aims to shed light on the mechanisms explaining shyness and confidence in response…

Parents may pass anxiety onto their offspring by exposing them to anxious behaviors in novel situations. Just as the parents’ anxious signals lead to anxiety, parents’ confident signals can ward off anxiety in the offspring. This project is seeking a new way to break anxiety transmission in the family…

Sasse, van Breen, Spears & Gordijn demonstrated an anger gap in response to sexism which was larger for women than for men and found evidence that expressed anger was associated with instrumental concerns.
