What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

Light-Harvesting Complex II (LHCII) is responsible for light absorption and excitation energy transfer in plants and photosynthetic algae, while in high light it undergoes conformational changes by which it quenches excitations to prevent photodamage.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

This thesis studied in depth the energy use and CO2 emissions of the industrial sector in China.

Has the industrial sector in China effectively been decarbonizing in recent years, across different regions and subsectors, and is it plausible that it will reduce its CO2 emissions in conformity with national and internationally pledged emission goals?

De 3D-spectrograaf Multi Unit Spectroscopic Explorer (MUSE) is met succes geïnstalleerd en in gebruik genomen op de Very Large Telescope op Cerro Paranal, Chili. MUSE heeft tijdens zijn eerste waarnemingsperiode gekeken naar verre sterrenstelsels, heldere sterren en andere testobjecten. De Sterrewacht…

Deze week ging de documentaire ‘Einstein’s Light’ tijdens het Leiden International Film Festival (LIFF) in première.

Het Story of Light festival dat plaatsvindt van 14 tot 18 januari 2015 in Panaji, Goa in India, is een initiatief van Jaya Ramchandani, alumnus van de masteropleiding Astronomy and Science Based Business. Het festival valt onder ‘The International Year of Light’, een project van de VN om de wetenschappelijke…

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.

In this thesis, bioorthogonal chemistry is combined with correlative light-electron microscopy to selectively label and study pathogenic intracellular bacteria within the host immune cell.

This thesis discusses the discovery potential of Intensity Frontier experiments.

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

Metal-based prodrugs based on ruthenium(II) polypyridyl complexes have proven to be very suitable for application in both photodynamic therapy (PDT) and photo-activated chemotherapy (PACT).

In this thesis the combinatorial use of bioorthogonal labelling and Electron Microscopy (EM)-based imaging techniques is explored to enable observations of specific molecular targets in their ultrastructural context within the cell.

In photoactivated chemotherapy (PACT), a biologically active compound is caged by a light-cleavable protecting group.

Gold nanoparticles show surprisingly strong interactions with light in the visible range, which can be divided into scattering, absorption, and photoluminescence.

Decentralized plug and play systems for energy production are the future picture of our society. Artificial photosynthetic systems are used for this purpose.

When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

A remarkable population of short period transiting rocky exoplanets with equilibrium temperatures on the order of 2,000 K has recently been discovered.

The field of exoplanet research is rapidly advancing through the development of new technology, observing techniques, and post-processing methods.

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

Surface plasmons (SPs) are surface waves at the interface between a dielectric and a good metal, and are formed by the interaction between light and the free electrons at the metal-dielectric interface. They provide strong field confinement for optical fields, opening new possibilities for enhanced…

In this thesis we have discussed several parameters that affect the electrochemical conversion of enviromentaly harmful molecules such as nitrates and carbon dioxide to more valuable and less deleterious compounds, in order to cast light onto the mechanism of the reaction to achieve an efficient and…

This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…

This thesis has shed light on some of the ways in which the local electrolyte composition can differ from the bulk and how these changes in the local reaction environment can determine the activity and/or selectivity of two important electrocatalytic reactions, namely, electrochemical CO2 reduction…

For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.
