Polycyclic aromatic hydrocarbons (PAHs) are the most abundant class of organic compounds in space. The PAH field evolves from the constant interaction between experimentalists, theorists, modellers and observers. While laboratory research and quantum chemical calculations together set up the molecular…

There are many complex links in the chain that provides patients with new drugs: from fundamental science, to clinical tests, to production. The entire chain can be found in Leiden. Leiden University, the Leiden University Medical Center (LUMC) and the businesses at the Leiden Bio Science Park (LBSP)…

Did he dare take a gamble with his PhD research? Jeroen Methorst didn’t have to think long about it. It could fail or turn out very well. The latter is the case. Methorst developed a computer system that helps researchers find the protein they need. ‘Our whole group is now using this program.’ Methorst…

Leiden physicists have been awarded 1.5 million euros for developing a hybrid microscope that provided nanometer-resolution. 'The idea is to combine the resolution of electron microscopy with the pros of optical microscopes.'

Science is under pressure and ‘alternative facts’ are increasingly being taken as truth. On 22 April, scientists will let their voices be heard on Museumplein in Amsterdam, for anyone with a passion for science. Zsuzsika Sjoerds is co-organiser of this March for Science and explains why knowledge is…

It’s about much more than learning how to write a readable piece or give a presentation that doesn’t send the audience to sleep. The intensive Science Communication Summer School gives young scientists the chance to really make contact with the public.

We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

Stacked layers of graphene can act like a mirror for beams of electrons. Physicists Daniël Geelen and colleagues discovered this using a new type of electron microscope. In an article in Physical Review Letters, they describe their results, which could lead to the development of optics for electron…

How can Ronald Mulder run his skates across an ice layer at 60 km/h? His skating blades get help from a lubricating layer of meltwater. In Leiden, physicists found this explanation to be incomplete. Theoretician Hans van Leeuwen and experimental physicist Tjerk Oosterkamp searched for a deeper answe…

Leiden Physicists have developed a new technique to visualize electrical conductance in sheet-like nano materials. It shows great promise for devices based on a new family of materials—the ‘Van der Waals materials’. The physicists, who won the 2015 Dutch Vacuum Society prize for their work, present…

Somatic symptoms, such as pain, itch, and fatigue have been shown to have a bidirectional relationship with mental symptoms. Although acute somatic symptoms serve some adaptive properties, chronic symptoms can instead lead to interference in daily activities and lower quality of life.

Plant Sciences' contribution to the Development & Disease research theme is to unravel the processes that allow plants to adapt to changing abiotic and biotic environmental conditions or stresses, with the aim to contribute to the sustainable production of food, flowers and bio-based products using…

How does the photoregulation mechanism work in detail?

The aim of the research programme is to provide insight into the cognitive processes and brain mechanisms that underlie reading, arithmetic and learning in general.

What is the mechanism of action preceding a physiological effects induced by metallic nanoparticles?

Which immune mechanisms are involved in host defense against Staphylococcal infection?

This thesis describes the use of the evolutionary approach in the study of language change, aiming to provide a better insight in the mechanisms that play a role in language change and to validate this approach in the field of language change.

Why is Crossnational and Cross-cultural agents such as Henrich Carloff and Willem Leyel important when studying Early Modern expansion?

In this article, Lydie Cabane, Assistant Professor at the Institute of Security and Global Affairs, and Martin Lodge address the question of how to manage banking crises, a question that has gained prominence since the banking crisis of 2007-2009. This article sets out the rationale for regulating for…

In this thesis we have discussed several parameters that affect the electrochemical conversion of enviromentaly harmful molecules such as nitrates and carbon dioxide to more valuable and less deleterious compounds, in order to cast light onto the mechanism of the reaction to achieve an efficient and…

In this thesis, we aimed to better understand the underlying mechanisms involved in TNBC progression and metastasis formation and discover new targets to reduce breast cancer related deaths.

What are the mechanisms involved in the reconciliation of value conflicts and which interventions are capable of resolving such disputes?

Glycoside hydrolases (glycosidases/GHs) are widely abundant enzymes in all kingdoms of life and are important biocatalysts that catalyze the hydrolysis of glycosidic linkages in oligo/polysaccharides, glycoproteins and glycolipids with tremendous efficiency

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.
