Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

Freshwater and brackish water ecosystems are arguably the most vulnerable ecosystems on earth, due to concentrated human developments in and around them. The Pontocaspian (PC) region located at the border of Europe and Asia contains a variety of brackish water ecosystems and unique inhabitants, known…

Exploring linkages between energy and material use and implications for sustainable development.

This thesis focusses on the temperature structure in protoplanetary disks. The relation between structures seen in the dust and gas-phase molecules is investigated.

Description of Development of a low cost technology for in-situ treatment of groundwater for potable and irrigation purposes (TiPOT) (2004 - 2007)

Op termijn zullen alle gebouwen een duurzame manier verwarmd en gekoeld worden, waardoor gas niet meer nodig is.

Io is één van manen van Jupiter, de grootste planeet in het zonnestelsel. Jupiter heeft wel negentig manen. Vier daarvan zijn veel groter dan de andere, en van die vier staat Io het dichtst bij Jupiter. Van de andere manen staan er maar vier nog dichter bij Jupiter.

Join the Pipe is een project dat zich inzet om plastic afval te verminderen en mensen zowel in het Globale Zuiden als in het Globale Noorden van drinkbaar water te voorzien.

Mars is de vierde planeet vanaf de zon en soms aan de hemel te zien als rode stip. De afstand tot de zon is ongeveer 228 miljoen kilometer. Een rondje om de zon duurt 687 aardse dagen. Een dag duurt bijna net iets langer dan op aarde, 24 uur en 40 minuten.

Multicopper oxidase, laccase, can efficiently reduce oxygen to water and are mostly used in the enzymatic biofuel cells.

Venus is de tweede planeet vanaf de zon en staat op 108 miljoen kilometer. Een jaar op Venus is korter dan op aarde en duurt maar 225 dagen. Doordat Venus heel langzaam om haar as draait, duurt een dag juist langer, wel 117 aarddagen! Op Venus is je alien dus elke twee dagen jarig.

Een techniek om CO2 om te zetten in brandstoffen en andere nuttige producten, is elektrolyse. Om dit efficiënt en op grote schaal te kunnen doen, moeten we wel precies begrijpen hoe elektrolyse werkt. Hoogleraar Marc Koper is expert op dit gebied.

How were the Russians, under early modern conditions, able to incorporate this distant, undeveloped and, because frequent nomadic attacks, dangerous territory? And what role did the Kolyvan-Voskresensk plants play in this process?

Het belangrijkste doel van dit onderzoek is om de steden van het Romeinse Nabije Oosten in de keizertijd in kaart te brengen, met een focus op locatie, stadsgrootte en stedelijke kenmerken, om de vorm van het stedelijke systeem en de niveaus van integratie te bestuderen.

Do e-waste workers display enhanced effects of adverse health effects due to informal e-waste processing in Nigeria? Is there a difference between the health outcomes of the exposed and the control groups? Are there difference in health effects within and between job groups (collectors, dismantlers,…

Taxonomy as a science has accumulated data and knowledge for more than 250 years.

This ecological community has long been known to affect host biology, and their diverse roles have been further clarified in recent years following numerous studies of animal:microbiota interactions in diverse systems.

This thesis revolves around the electronic spectroscopy of molecules in the laboratory and the search for the carriers of the diffuse interstellar bands (DIBs).

The main object of study in this thesis is an Arakelov inequalitywhich bounds the degree of an invertible subsheaf of the direct image ofthe pluricanonical relative sheaf of a semistable family of curves.

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

Where does the urge to collect come from? What are the explicit or underlying reasons for gathering large amount of objects?

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

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

Polycyclic aromatic hydrocarbons (PAHs) are the most abundant class of organic compounds in space. The PAH field evolves from the constant interaction between experimentalists, theorists, modellers and observers. While laboratory research and quantum chemical calculations together set up the molecular…

HEPGAME is a research project that combines the world’s fastest computer algebra system for High Energy Physics equations, FORM, with insights from artificial intelligence. The name combines High Energy Physics and Games.

Plant diversity is essential for us and our planet as it sustains the stability of our ecosystems, provides vital materials and food to us and supports many ecosystem services.

Heterogeneous catalysis is essential to many industrial applications. These catalysts are often comprised of supported nanoparticles, which contain various different surface sites.

Given the accelerating appearance of antimicrobial resistance, there is an urgent need for more fundamental research into novel antibiotic strategies. The work in this thesis helps to address this global problem by developing new antibiotic compounds, inspired by the antibacterial mechanisms of the…

This thesis is about the study of hydrocarbons via infrared spectroscopy.

This dissertation is about Bayesian learning from data. How can humans and computers learn from data?

This thesis provides explicit expressions for the density functions of absolutely continuous invariant measures for general families of interval maps, that include random maps and infinite measure transformations, not necessarily number systems.

In this thesis we study bistable reaction-diffusion equations on lattice domains.

Quantum computing is an emerging technology, which holds the potential to simulate complex quantum systems beyond the reach of classical numerical methods.Despite recent formidable advancements in quantum hardware, constructing a quantum computer capable of performing useful calculations remains challenging.In…
