Solar energy is used by photosynthetic organisms to drive energy required cellular processes. Is absorbed by two groups of pigments, located in the LHCs.

De strijd om het presidentschap van de Verenigde Staten wordt vaak afgeschilderd als een nek-aan-nekrace. De twee belangrijkste kandidaten, Hillary Clinton en Donald Trump, lijken even populair (of impopulair) en media laten niet na te benadrukken hoe klein de marge is tussen winst en verlies. Dat is…

In the thesis we demonstrated an 85% state transfer efficiency between two mechanical modes coupled to a common optical mode via stimulated Raman adiabatic passage (STIRAP) in the classical regime. We also showed possibilities to manipulate quantum states of the mechanical modes via STIRAP.

Op 23 september jl. vond in het Hof van Saksen in Nooitgedacht (gemeente Aa en Hunze, provincie Drenthe) het jubileumcongres plaats ter gelegenheid van het honderdjarig bestaan van de Vereniging van Drentse Gemeenten.

In this thesis, I targeted the orchid genus Lepanthes, one of the six genera of angiosperms that surpasses 1,000 species in the Neotropics, as a study model to investigate the evolutionary processes that promoted species diversifications.

Niels van Willigen (Instituut Politieke Wetenschap, Universiteit Leiden) plaatst de Nederlandse deelname aan VN vredesmissies in een historische context. Hij bekijkt de redenen voor een afname van de Nederlandse inbreng na 1990 en verkent de obstakels en mogelijkheden voor een ‘Nederlandse terugkeer’…

Met de NMR faciliteit doen we onderzoek naar de synthese van paramagnetische moleculen om kennis te vergaren over de structuur en dynamiek van eiwitten. Deze kennis kan dienen als basis voor een medicijn dat zich hecht aan een eiwit of voor de ontwikkeling van vaccins. Medicijnontwikkeling is één van…

Op 1 juni 2022 verdedigde Tom Herrenberg het proefschrift 'Prosecutorial Discretion in International Criminal Justice'. Het promotieonderzoek is begeleid door prof.dr. P.B. Cliteur en prof.dr. B.R. Rijpkema.

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

The main aim of this project is to reveal and unravel the invisible histories of the UN, transcending the dominant Western perspective to recover the historical agency of Global South actors. The research will investigate how the UN has both facilitated and limited their role in shaping global order…

What holds people together and what makes them willing to fit within larger political structures? Our project examines this question in the practices of dynastic rulership in Eurasia ca. 1300-1800.

The Economics and Governance specialisation of the Master in Public Administration teaches you to formulate problem-solving approaches to concrete policy issues found at the intersection between economics and public administration. This specialisation is a unique joint offering of the Department of…

Op 18 september 2019 verdedigde Huw Llewellyn zijn proefschrift 'An Institutional Perspective on the United Nations Criminal Tribunals: Governance, Independence and Impartiality'. Het promotieonderzoek is begeleid door promotoren prof.dr. N.M. Blokker en prof.dr. L.J. van den Herik.

This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process.

This thesis presents insights from our study of various correlated electron systems with a scanning tunneling microscope (STM). In ordinary metals, electron-electron interactions exist, but get substantially screened due to the sheer number of electrons.

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.

During my PhD research, I studied the photon statistics of light emitted by a microcavity that contains a single quantum dot (QD) on resonance.

The aim of the research presented in this thesis was to develop new methods forchallenging systems in liquid-state NMR using paramagnetic effects generated by thetwo-armed probe CLaNP-5.

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

The way organisms develop from the initial single-cellular state to a complex final assembly like the human body, and how the final body is maintained throughout life, is one of the greatest mysteries and it’s understanding one of the biggest scientific challenges.

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

This thesis described the development of novel scanning tunneling microscopy techniques to investigate strongly correlated electronic states in quantum matter.

Kidney transplantation is a major advance of modern medicine. This course will give you state of the art updates about what used to be an experimental, risky, and very limited treatment option more than 50 years ago and is now routinely performed in many countries worldwide.
