Bacterial biocatalysis constitutes a sustainable alternative for high-value chemicals production by enabling the utilization of renewable feedstocks.

The expanding population and economic activity are driving up global energy consumption. Simultaneously, there is an urgent need to transition from fossil fuels to renewable sources to mitigate the climate crisis, primarily caused by fossil fuel combustion.

Our students and staff have strong feelings and deep concerns about the ties between Dutch universities and the fossil fuel industry. It’s a thorny issue and as a university we’re keen to chart our course for the future, but we cannot do so alone. I therefore hope to be able to discuss the matter with…

PhD researcher David Font Vivanco, together with Ester van der Voet, Reinout Heijungs and Renée Kemp (Maastricht University) won the Graedel Prize 2014 for best paper published by a junior author in the Journal of Industrial Ecology.

This thesis describes the antimicrobial discovery strategy developed in our group, the den Hertog Group at the Hubrecht Institute. It includes a cultivation-based screening approach for novel antimicrobial agents from the source of fungi, and a bacterial time-lapse imaging approach for antimicrobial…

This project aims at determining the market value of hydrogen peroxide (HP) that is produced via our electrochemical methods that have been developed as part of the ERC-StG Cu4Energy project.

This thesis addresses the importance of a resilient supply of critical raw materials (CRM) for the global energy transition.

CompaRe’s third virtual PhD roundtable was held on 29 March 2023. In attendance were the head of the centre, staff and PhD candidates. The roundtable focused on brainstorming a wide range of questions around the research process.

This thesis is an experimental study of the UV irradiation of the interstellar ice analogues, relevant for the different stages of the star and planet formation sequence.

Humanity stands at a pivotal juncture, facing the dual challenge of environmental sustainability and rapid population growth, projected to exceed 11 billion by century’s end.

Portraits of six Leiden professors for whom 8 February 2016 was the first time that they took part in the procession of Leiden professors at the Dies Natalis.

An extra-long procession with musical accompaniment will mark the beginning of the university’s 450th birthday celebrations on 7 February.

How to reconstruct the middle parts (videlicet haute-contres, tailles and quintes) from French orchestral pieces, which survived only in their reduced forms (featuring primarely dessus and continuo), according to historical examples?

This thesis examines enzyme domain architecture and engineering to improve the breakdown of lignocellulose and starch, abundant biopolymers crucial for sustainable biofuel and biochemical production. Carbohydrate-active enzymes (CAZymes) facilitate this degradation, but the structural complexity of…

In this dissertation the author digs into the constituent elements of River Plate tango in order to decode how specific musical materials were organized and combined by four outstanding musicians: Pugliese, Salgán, Piazzolla and Beytelmann.

Research and design are two activities that are becoming increasingly important in the Dutch subjects O&O (‘research and design’) and NLT ('nature, life and technology’). The dissertation of Tessa Vossen (ICLON and Faculty of Science) indicates that teachers and students understand the importance of…

Marius Staring, Associate Professor at the LUMC has been awarded the Chan Zuckerberg Initiative funding for further development of image processing software Elastix

The upscaling of Life Cycle Assessment (LCA) data is recognized as one of the main challenges in the ex-ante LCA of emerging technologies. This challenge arises since industrial-scale system specifications for these technologies are unknown and industrial data is lacking.

Welcome to the Dutch Extract Library, the library of the majority of crop extracts grown in Dutch horticulture.

As of 1 February 2009, PhD applications should no longer be sent to the International Office to be processed. The Graduate School will deal with its own applicants in future.

National Meat Free Week, from 11 to 17 March, encourages us to choose the environmentally friendly option more often. But apart from preventing animal suffering, does eating less meat really make much difference? Three questions for Leiden Professor of Industrial Ecology Arnold Tukker.

Laboratory, observation and modeling work on the dissociation of polycyclic aromatic hydrocarbons in interstellar environments and the formation of new molecular species through the fragmentation process.

This thesis consists of two main parts. The first part (Chapters 2 and 3) deals with a class of Markov process called Quasi-Skipfree (QSF) processes.

Patients with the same illness often receive the same treatment, even if the cause of the illness is different for each person. This represents a new step towards ultimately being able to offer every patient more personalised treatment.

The research programme Probability Theory focuses on probability theory and on operations research.

With the aid of the General History of Africa (GHA) series of books, PhD candidate Larissa Schulte Nordholt researched what it meant to decolonise the history of Africa. This proved to be a tricky process, which was hampered by politics and lack of funding. PhD defence on 1 December.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

At the Leiden Curious Minds Centre, our research focuses on the relationship of exploratory behaviour and discovery learning to curiosity and the way children regulate their behaviour and emotions. We want to improve our understanding of how children can and do become more and more the captain of their…
