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…

The marine shipping industry is one of the strongest emitters of nitrogen oxides (NOx), a pollutant detrimental to ecology and human health. Over the last 20 years, the pollution produced by power plants, the industry sector, and cars has been decreasing.

The class-imbalance problem is a challenging classification task and is frequently encountered in real-world applications. Various techniques have been developed to improve the imbalanced classification performance theoretically and practically.

Almost three years after receiving her honorary doctorate, Dr Graça Machel returned to Leiden University. Over the course of two days she spoke with students, researchers, and other interested persons, about human rights – particularly those of women and children – in a world in which these are continually…

Carbohydrates are present on the surface of bacteria making them suitable antigen candidates for vaccine development. This thesis deals with the synthesis of two carbohydrate-based components; the capsular polisaccharide of S. aureus type 5 and teichoic acids from staphilococci and enterococci speci…

Innovation plays an essential role in firms' competitiveness and long-term success. It varies from different types, ranging from run-of-the-mill innovation that brings incremental changes to existing technologies to radical innovation that breaks from existing trajectories.

The aim of this thesis is to expedite and ensure the systematic accuracy of clearance scaling from adults to paediatric patients, with a special focus on drugs undergoing hepatic metabolism.

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

Glycoconjugate vaccines are composed of microbial poly- or oligosaccharides covalently linked to a carrier protein.

This thesis focuses on two processes involved in fighting infections: metabolism and immune cell motility and navigation.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

In this thesis, we have studied cell images from two types of cells, including pollen grains and the immune cells, neutrophils. These images are captured using a bright field microscope and a confocal microscope.

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.

Onder welke omstandigheden beperken paramilitaire groepen hun gebruik van politiek geweld? Dit artikel onderzoekt het gebruik hiervan door de PIRA.

Ramesh Ganohariti onderzoekt de juridische identiteit in drie post-Sovjet aspirant-lidstaten en schetst in dit artikel vier veelvoorkomende scenario's.

Jaroslaw Kantorowicz and Rok Spruk onderzoeken de bijdrage van institutionele hervormingen aan economische groei.

This study seeks to analyse how job stress could be the result of performing administrative tasks

Om de klimaatcrisis het hoofd te bieden, kan een bepaalde nederigheid van de mens ten aanzien van de natuur van groot belang zijn. Tegelijkertijd kan nederigheid ook politieke overheersing in de hand werken. Hoe kunnen mensen zich op een bescheidener manier tot de natuur verhouden zonder hun vrijheid…

Dit artikel levert een bijdrage aan een groeiend aantal onderzoeken naar radicalisering. Het richt zich specifiek op het onderscheid tussen individuen die radicalisering en daardoor betrokken raken bij terroristisch geweld en individuen die radicaliseren maar niet betrokken raken bij geweld.

Op 30 september 2021 verdedigde Babette van Hazebroek haar proefschrift 'Understanding delinquent development from childhood into early adulthood in early onset offenders'. Het promotieonderzoek is begeleid door promotoren prof.dr. J.W. de Keijser en prof. dr. A. Popma (VUMC).

Dit artikel gaat in op de onderzoekskloof door te onderzoeken hoe deze instanties hun personeel zo kunnen inzetten dat ze maximale prestaties leveren met het personeel dat ze hebben.

The thesis explores how interstellar chemistry evolves as a function of time and changing physical architectures during the formation of stars.

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

Religion and ethnicity are inextricably linked in discourse within and about Central Asia. One common narrative suggests that as a result of differences between historically sedentary and nomadic populations, ethnic Tajiks and Uzbeks are naturally more religious and more likely to radicalise than their…

A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

In this thesis, we aim to shed light on the diverse and often opposing roles of integrin α3β1 in cancer.

The origin and evolution of galaxies are closely linked to many different physical phenomena.
