In this thesis we investigate cosmology and the large scale structure of the Universe using cosmological simulations.

This research focuses on the distribution of chemical elements in protoplanetary disks, the birthplaces of planets. These disks form around young stars and contain gas and dust, from which planets grow. Ice plays a crucial role in planet formation, aiding the clumping of dust particles and influencing…

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

ICEHL will take place in Leiden on 7-11 June, 2021.

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

Cardiovascular disease is the leading cause of death worldwide.

Exploring Late Bronze Age attitudes towards martiality through experimentation and micro-wear analysis

Hydrocarbonylation of alkenes with carboxylic acids in synthesis of carboxylic acid anhydrides is relatively less explored. We herein present a study and optimization of a palladium-catalyzed hydrocarbonylation reaction of alkenes using carboxylic acids as the nucleophile, by which acid anhydrides can…

Stars and planets form within cold, dense clouds of gas and dust drifting through interstellar space. Although dust makes up only a small fraction of this material, it plays a key role in shaping the chemical evolution of these environments.

The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…

How does open government affect the level of public trust?

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

The main goal of the THEOR CHEM group, headed by Prof. Geert-Jan Kroes, is to characterize, and to accurately predict the outcome of chemical reactions at gas-solid and liquid-solid interfaces. Here the solid surface is typically a metal or an ice surface. These goals are important to many areas in…

Supramolecular polymers are class of materials that are formed by non-covalent interactions such as hydrogen bonding, π-π interactions, electrostatic interactions and the hydrophobic effect.

A key step in the synthesis of oligosaccharides and glycoconjugates is the formation of the glycosidic bond.

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

Mining the unusually rich diaries, memoirs, and poems written by Netherlandish Catholics, Judith Pollmann explores how Catholic believers experienced religious and political turmoil in the generations between Erasmus and Rubens.

These aspects make the Creative Intelligence & Technology MSc program unique:

The research project of Yannis Patoukas proposes to explore the different intersections between experimental rock music of the 1960s and 1970s and electroacoustic music, with regard to studio practices and production techniques and their creative possibilities.

A 24 person classroom on the floor 0 of the Pieter de la Court building. Designed for groupwork, rolling, flexible tables and chairs are arranged around shared monitors. Each group has a small whiteboard. The frontal projection point has a short-throw projector with motion tracking and live annotation.…

In 2023, the OSCL, together with the University Library and Academia in Motion, ran a survey to better understand the state of Open Science at our university. In this year's follow-up, we are asking you to give your input, so we can jointly develop how Open Science evolves in our university.

Every week, ISGA organizes the Research Seminar Series discussing works from ISGA staff and externals.

The specialisation combines one year of Mathematics research (60 - 80 EC) with one year of science communication courses, internships and research (40-60 EC).

FAIRDOM consortium is an open initiative of various partners including funding programmes, large-consortia, institutes, small groups as well as individuals.

An international team of astronomers led by Ardjan Sturm of the Observatory has made the first two-dimensional inventory of ice in a planet-forming disk of dust and gas surrounding a young star. The researches, including Melissa McClure, used the James Webb Space Telescope and publish their findings…

In Germany, the United States and even in Vietnam: all over the world, the Leiden discovery of the birth of two planets was shared. Astronomer Sebastiaan Haffert and his team were able to record multiple planets in the making for the first time and published their findings in Nature Astronomy. A unique…

The Hague Journal of Diplomacy only accepts online submission of articles through its Editorial Manager.

The Faculty of Social and Behavioural Sciences is committed to being a safe, comfortable, and equitable space for both staff and students: a place where a diversity of people feel valued and welcome, where there is room for a diversity of perspectives.

NASA’s telescope SOFIA has provided a new glimpse of the chemistry in the inner region surrounding massive young stars where future planets could begin to form. Leiden PhD candidate Andrew Barr writes about it in the Astrophysical Journal. The scientists found massive quantities of water and organic…

Hydrogen peroxide (H2O2) is an important bulk chemical that is used in various industrial processes. More than 95% of the H2O2 used in industry is made via the anthraquinone process during which a large amount of energy is going to waste.

On 15 February 2022, Morshed Mannan defended the thesis 'The Emergence of Democratic Firms in the Platform Economy: Drivers, Obstacles, and the Path Ahead'. The doctoral research was supervised by Prof. I.S. Wuisman and Prof. J.A.A. Adriaanse.

Therapeutic proteins have revolutionized the treatment of many severe diseases like multiple sclerosis, haemophilia, diabetes and many more. Unfortunately, even recombinant proteins with structures (almost) identical to those of their endogenous counterparts often induce the formation of anti drug antibodies…

Macrophages and atherosclerotic lesions The infiltration of monocytes in the arterial wall, their differentiation to macrophages, and the subsequent accumulation of cholesterol in these macrophages initiate the process of atherosclerosis. We study the importance of specific genes in macrophages for…
