Organic amendments applied to agricultural fields can partially offset our carbon emissions to the atmosphere and improve the resilience of agriculture to the effects of climate change. Driving these benefits, however, are complex and poorly understood interactions between organic amendment properties,…

This thesis examines the link between simple molecules and the underlying structure and chemistry within protoplanetary disks - the birthplaces of planets.

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.

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

The thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

In juli zal een aantal onderzoekers van de Afdeling Jeugdrecht een paper presenteren op de 'Culture, Dispute Resolution and the Modernised Family' conference in Londen, georganiseerd door het International Centre for family law, policy and practice te Londen.

This dissertation was to develop effective graphene-based nanofluidic devices by developing scalable fabrication methods and elucidating proton transport mechanisms.

De ontwikkeling en implementatie van een schaalbare, veilige en geïntegreerde infrastructuur van waterstof te bevorderen ter ondersteuning van de energietransitie.

In this thesis we study products of linear error correcting codes.

In the traditional theory of linear elasticity, superposition dictates that the response of a material does not depend on the sequence of the applied mechanical actuations.

N-acylethanolamines (NAEs), including N-arachidonoylethanolamine (anandamide, AEA), N-palmitoylethanolamine (PEA) and N-oleoylethanolamine (OEA), are signaling lipids that play an important role in different physiological process.

Intensive 5-day programme on the world-famous Antwerp-based printing and publishing house founded by Christopher Plantin in 1555. International experts will discuss how it developed the production and distribution of religious books and related illustrations and prints in the following centuries.

Over the past two centuries, socioeconomic development has improved material living standards but has also intensified environmental pressures, including climate change and biodiversity loss.

Dit artikel biedt een systematisch literatuuronderzoek van de belangrijkste principes, normen en strategieën van Security by Design en Privacy by Design.

In oktober werd Sophie Starrenburg gekozen tot lid van het coördinerende comité van de ESIL ‘Interest Group on the International Law of Culture’. Ze zal hierin samenwerken met Giovanni Carlo Bruno (Italian National Research Council), Andrzej Jakubowski (Polish Academy of Sciences) en Lucas Lixinski…

The majority (80%) of e-waste generated globally are recycled informally in developing countries.

In 2009-2010 ontstond in het westerse discours het idee van een meer ‘assertief’ China, een opvatting die China krachtig van de hand wijst. Niettemin is, vooral sinds Xi Jinping in 2012 aan de macht kwam, duidelijk dat China zijn lang gehanteerde buitenlandse beleidsdoctrine van ‘een lage profilering…

OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.

The lysosomal β-glucosidase named glucocerebrosidase (GCase) is a retaining β-glucosidase that hydrolyzes the glycosphingolipid glucosylceramide (GlcCer) to ceramide and glucose at acid pH.

Synthesis and application of chemical biology tools to study immunomodulatory signaling lipids.

Glycosidases are essential in fundamental biological processes and are responsible for the degradation of most (oligo)saccharides, glycolipids and glycoproteins.

Why do sexual violence policies still fail to systematically address men and masculinities, when the need for cultural change among men has been central in public debates since #MeToo?

The dissertation offers new tools and insights to computation and modelling of topological phases, with an emphasis on the aperiodic setting.

Een nieuw tweejarig masterprogramma Duits, verzorgd door vijf universiteiten, moet gaan voorzien in de grote vraag naar eerstegraads docenten Duits in het voortgezet onderwijs. De Universiteit Leiden is penvoerder van het programma.

Nanodiscs are small, disc-shaped structures designed to mimic biological cell membranes, composed of a lipid bilayer stabilized by scaffold proteins. Membrane proteins play crucial roles in essential processes such as nutrient and waste transport, molecular recognition, and cell signalling, making them…

The intradermal administration route is attractive for vaccine delivery, because of the highly populated antigen-presenting cells in the skin. However, the skin’s main physical barrier, the stratum corneum, prevents vaccines from entering the skin.

Op 16 december 2021 verdedigde Lisanne van Houten het proefschrift 'Flexing the Slot Regime'. Het promotieonderzoek is begeleid door prof.dr. P. Mendes de Leon en prof. L. Pierallini (Luiss University Of Rome).

Carbonaceous asteroids preserve a record of early solar system processes, where minerals and organic molecules, like polycyclic aromatic hydrocarbons (PAHs), offer clues to planetary evolution and prebiotic chemistry.

This thesis revolves around the electronic spectroscopy of molecules in the laboratory and the search for the carriers of the diffuse interstellar bands (DIBs).

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.

In this thesis, we present new laboratory data of interstellar dust analogues.

Global Environmental Extensions Multi-Regional Input-Output (EE-MRIO) analysis is often used to analyze how changes in global and national demand for products lead to socioeconomic and environmental impacts at the national level.

One of the key discoveries in exoplanet research over the past decade is the abundance of small planets in our Milky Way. Despite their high numbers, our understanding of their atmospheres remains limited, and it is unknown if they possess atmospheres at all.

The external tissues of plants and animals are colonized by microbial communities termed microbiota. When organisms are exposed to environmental pollutants, these substances will therefore encounter microbiota at the exposure interface.

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.
