The endocannabinoid receptors CB1R and CB2R are involved in a plethora of processes, and consequently are involved in many pathological conditions. Their wide distribution makes the CBRs both an interesting therapeutic target and hard to study.

This thesis investigated miniaturized mass spectrometry (MS)-based analytical methods to address challenges in analyzing biomass-restricted biological samples.

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 thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

In this thesis we push the boundaries of high-resolution imaging at radio frequencies between 100 and 200 MHz. Using the International LOFAR Telescope that spans across Europe we achieve sub-arcsecond angular resolution.

This course explores international arbitration as one of the most common methods of international dispute settlement. You will gain an in-depth understanding of international arbitration through the analysis of its role as a mechanism of dispute settlement, its institutions, the fields of law it is…

This thesis examines the impacts and challenges of water use of electric power system. This thesis found that there are large differences in water use of electricity technologies, with hydropower and thermal power being two large water users.

Dit is een vergelijkende studie naar het proces van omzetting of herroeping van vrijheidsbeperkende sancties in 10 Europese landen.

Kevin speelt hedendaags repertoire dat zich onderscheidt doordat de lichamelijk handelingen die nodig zijn om deze muziek uit te voeren in de notatie van elkaar losgekoppeld zijn. Dit heet ook wel physical polyphonic notations, een unieke en relatief recente trend in de muziek waarbij naast de noten…

Songbirds as vocal learners learn their songs and song preference from social tutors⁠. Tutor choice for both song and preference learning are important to characterize for understanding individual learning performance and cultural transmission of song⁠.

Streptomyces are prolific producers of enzymes and secondary metabolites, including more than 50% of all clinical antibiotics. This makes them highly attractive for medical, biotechnological, and industrial purposes.

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…

The disease acute myeloid leukemia (AML) is characterized by fast progression and low survival rates.

This doctoral thesis is an effort to understand how lipid phase-separation induced by diacylglycerol analogues in lipid-based nanoparticles affects their in vivo behavior, leading to specific nanoparticle-protein communications and selective cell targeting.

This thesis advance our understanding and the application of molecular catalysts relevant to the reduction of oxygen as well as reduction of nitrite.

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

Like a mixture of oil and water, lipid membranes separate into two liquid phases.

Fundamental understanding of molecular reactions on metal surfaces is important for improving heterogeneous catalysis.

Electrocatalysis allows for storing electricity or converting it into chemical bonds, producing chemical building blocks and fuels using renewable resources.

The formation of stars and planets happens over multiple scales, which can interact. In particular, planet formation happens in the dense, complex environment of star forming regions.

Multicellular giant algae Chara species have been widely used in physiological studies for decades.

Malte Riemann onderzoekt de evolutie van het huurlingenconcept. Hij stelt dat het idee van de huurling in het 19e-eeuwse Europa ontstond.

Academici hebben op het gebied van inlichtingen geworsteld met de vraag onder welke voorwaarden internationale samenwerking op het gebied van inlichtingen plaatsvindt. De meeste richten zich op transactionele motieven en gegarandeerde opbrengsten, de zogenaamde ‘Quid pro Quo’. Tegelijkertijd wordt vertrouwen…

In dit artikel bespreekt Vanessa Newby, universitair docent bij het Instituut Security and Global Affairs, geloofwaardigheid in vredesoperaties. Het artikel betoogt dat geloofwaardigheid in vredesoperaties moet worden opgebouwd met het oog op zowel afschrikking als samenwerking.
