Twee onderzoekers uit de onderzoeksgroep Plant ecology and Phytochemistry van het Instituut Biologie Leiden hebben beurs gekregen van de Stichting Technologische Wetenschappen.

Plant architecture has distinct forms in different plant species, but also within a species the finalarchitecture of a plant is determined by its gradual development and changes therein induced by environmental conditions during the plant’s life cycle.

Almost all bacteria are enveloped by a cell wall that provides cellular protection.

In this thesis new methodologies are developed for the detection and systematic study of radio sources in the early universe. This allows us to gain a deeper understanding of the formation and evolution of galaxies, the activity of supermassive black holes, and the final phase transition of our universe:…

Supramolecular polymers are class of materials that are formed by non-covalent interactions such as hydrogen bonding, π-π interactions, electrostatic interactions and the hydrophobic effect.

Cardiovascular disease is the leading cause of death worldwide.

This thesis is largely an experimental study on the formation of solid-state simple and complex organic molecules in the H2O-rich and CO-rich ice phases of dense interstellar clouds and dark cores.

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…

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

2.240 plantenextracten van 1.299 verschillende plantensoorten van Nederlandse bodem. Dat is de collectie van de Dutch Extract Library, die onlangs is overgebracht naar het Instituut Biologie Leiden. Voor Pingtao Ding, plantenbioloog en contactpersoon van deze bibliotheek, is dit een ware schatkamer.…

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…

Tracing the evolution of the molecular gas content in galaxies is critical for a complete understanding of galaxy formation and evolution, as it provides the direct fuel for star formation. Studies of high-redshift (z>1) molecular gas reservoirs, most commonly traced by carbon monoxide (CO), have seen…

Invasive lobular carcinoma (ILC) is the second most common type of breast cancer.

The applications of studying the early development of insects range from agriculture to material science.

This work describes several studies into the electroreduction of carbon dioxide (CO2RR), both regarding mechanistical aspects and catalyst stability considerations. Mechanistic insights into carbon-carbon bond formation on a silver catalyst are described in Ch 2, were we find an acetaldehyde-like surface…

Welke stoepplanten groeien waar en waarom? Hoe maken we de stad groener? En hoe genezen we plantenblindheid? Het antwoord op deze vragen zoekt Nienke Beets, PhD kandidaat stadsflora en citizen science, samen met de nieuwsgierige burgers van Nederland.

De tentoonstelling Beschermde planten in de Hortus botanicus laat het belang van biodiversiteit zien aan de hand van verhalen over beschermde planten. Geert de Snoo, decaan van de faculteit der wiskunde en natuurwetenschappen en hoogleraar Conservation Biology, opende de tentoonstelling op 22 mei 2015,…

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

Op donderdag 17 oktober organiseerde de masteropleiding Crisis and Security Management (CSM) een informatief alumni-panel met vijf afgestudeerden uit verschillende cohorten. Het panel bood huidige studenten de kans om te luisteren naar professionals die hun eigen weg hebben gebaand in crisis- en vei…

What are the global relationships between environmental conditions and abundance of distinct types of mycorrhizal fungi in soil and plant roots?

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.

Within this thesis the central stage is taken by the discovery and investigation of transglycosylation of sterols. First, investigation focuses on the development of a method to accurately detect and quantify glucosylated metabolites in biological materials.

Dr. Remko Offringa is met ingang van 1 september 2016 benoemd tot Opleidsingsdirecteur van de masteropleiding Biology. Hij volgt daarmee Johan Memelink op.

In de Hortus botanicus heeft de penisplant Amorphophallus decus-silvae korte tijd in bloei gestaan. Na twee dagen was de bloei voorbij en is het stuifmeel, dat de mannelijke bloempjes hebben geproduceerd, verzameld. Voor zover de plantenexperts in de tuin kunnen nagaan, was dit pas de derde keer dat…
