In dit artikel doen Bart Schuurman en Sarah Louise Carthy onderzoek naar de oorzaken van terrorisme door verschillen en overeenkomsten tussen links-, rechts- en jihadistische extremisten te vergelijken.

Politicologen Rebekah Tromble en Michael Meffert (Universiteit Leiden) analyseren waarom sommige media frames aanhouden, terwijl andere frames snel in de vergetelheid geraken. Zij ontwikkelen een methode die is ontleend aan event-history. De casus die Tromble en Meffert bekijken, is de verslaglegging…

Marine sponges are important members of reef ecosystems, as they play ecological roles that are essential for the health of the reef.

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

The adenosine receptors are proteins that reside in the extracellular membranes of cells. Activation of adenosine receptors plays a role in many physiological and pathological processes, such as immune responses and cancers.

This thesis combines field and laboratory studies to address some of the most pressing questions in the field of microplastic research.

A difficulty of studies on chemical kinetics are the reaction time scales and detection of their intermediates.

How to make a quantitative assessment of the relative contribution to toxicity of ions and particles? Is the toxicity of nanoparticles related to their size or shape? Which physicochemical property of nanoparticles is an appropriate dose metric of nanoparticles?

Plant exudates appeared long time ago in the history line of life in the early Devonian. They are typical saps produced by specialized cells.

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.

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

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.

Is er sprake van een tanende legitimiteit van het recht en bestuur in een veellagige rechtsorde en welke betekenis heeft (afnemende) legitimiteit voor de effectiviteit van het recht?
