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.

Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

In this thesis, we develop a novel technique called Optical Near-field Electron Microscopy (ONEM), which aims to combine the advantages of both optical and electron microscopy: the high resolution of electron microscopy and the low sample damage of optical microscopy.

The thesis describes terrestrial field trials aimed to detect side-effects of pesticides within the framework of pesticide registration procedures. Field trials were developed using vascular plants Brassica napus and Poa annua, caterpillars Pieris brassicae and effects on decomposition were studied…

Het Solar Fish-project van hoogleraar biofysische organische chemie Huub de Groot, krijgt een plaats in het Llowlab op popfestival Lowlands.

Make more fluid: In condensed matter systems, electrons can acquire unusual properties from their interaction with the atomic lattice.

In this work we describe three methods to improve the performance of Quantum Field Theory calculations.

This thesis describes the implementation and on-sky demonstration of high-resolution integral-field spectroscopy for extreme adaptive optics systems that are used to find and characterize exoplanets.

The solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

This thesis investigates the relations between metabolism and anatomy through the use of Magnetic Resonance Imaging (MRI).

The redox-conversion reaction of metal-disulfide and metal-thiolate complexes are important, as they may shed light on electron-transfer reactions that often occur in Nature.

On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

The Honours Class From Solar to Fuel with Bio bestond vrijwel geheel uit de workshop Solar Biofuels from Microorganisms die eind maart/begin april ruim tachtig specialistische onderzoekers naar het Lorentz Center trok. De studenten Erica Wenker (scheikunde) en Jasper van Dobben de Bruijn (rechten) schreven…

In this thesis, we show that we can use Shimura’s CM theory to explicitly compute the Hilbert class field of any primitive quartic CM field.

Hoogleraar getaltheorie Manjul Bhargava heeft een Fields Medal gekregen, ook wel de ‘Nobelprijs voor de wiskunde’ genoemd. Dat is woensdag 13 augustus 2014 bekend gemaakt. Bhargava is hoogleraar in Princeton en daarnaast sinds 2010 Stieltjes hoogleraar in Leiden. 'Alles wat hij aanraakt verandert in…

Scattering of light in the presence of nano-structured materials, i.e. with features in the order of the wavelength of the light or smaller, reveals details of how light interacts with matter at the nanoscale.

With increasing carbon dioxide levels in the atmosphere and their detrimental effect on the global climate, modern society needs to push for more renewable energy sources. Storing widely accessible and abundant solar energy in chemical bonds in the form of molecular fuel via artificial photosynthesis…

The energy system is at the heart of two of the greatest challenges of the 21st century: decreasing CO2 emissions to meet the ambitions of the Paris agreement while fulfilling the growing energy demand associated with the economic aspirations of a growing world population.

In this thesis, classes of strongly interacting quantum field theories, have been studied.

Archeoloog Mike Field besteedde zijn vakantie in augustus aan de zwaarste paardenrace ter wereld, de Mongol Derby: duizend kilometer in tien dagen over de Mongoolse steppe, de postbodes van Dzjengis Khan achterna. Field werd drie keer uit het zadel geworpen maar haalde de finish.
