Low energy electron transmission through layered materials and chiral organic films
In this Ph.D. thesis we study the interaction of low energy electrons with thin materials, namely layered materials (graphene, hexagonal boron nitride, molybdenum disulfide) and organic films. At these low energies the quantum mechanical wavelength of the electron wave function is in the order of a…

Play by the rules? : coordination of EU sustainable development policies and the importance of the politico-legal context
There is an increasing amount of attention on EU and its Member States contributions to implementation of two landmark agreements: the Paris Climate Agreement and the UN Agenda 2030 with Sustainable Development Goals (SDGs). Absent from the current literature is an analysis of the political effect of…

Satellite remote sensing of plant functional diversity
Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

Column Rob Visser: Kabinetsformatie ‘mislukt’? Geef het de tijd
Direct na de vorige fase in de kabinetsformatie werd het wijd en zijd geroepen: het is mislukt, wij zijn weer terug bij af. Voor de partijen die niet bij die formatiefase waren betrokken, is dat een begrijpelijke debat-truc. Door dat zo te zeggen, wordt geïmpliceerd dat de onderhandelende partijen onverantwoordelijk…

Column Rob Visser: Vrijheid van meningsuiting, ambtenaren en demonstreren
Terwijl de kabinetsformatie gewoon doorgaat en ons via de media bezighoudt, gaat ook de rest van de wereld door. Dat is voor sommigen, velen zelfs, aanleiding om daar aandacht voor te vragen. Ook ambtenaren laten zich daarin horen. Voor de ingang van het ministerie van Buitenlandse Zaken worden zelfs…

Column: Crisis, Kiezen en Formeren
De verkiezingen komen er weer aan. Het gevolg van een kabinetscrisis. Politici en media wijzen uitgebreid op 'de issue' waar het om ging. De oorzaak van de breuk wordt breed uitgemeten. Maar is dat wel de oorzaak?

Column Rob Visser: De veerkracht van de Rechtsstaat
Het is weer zover. Het proces van kabinetsformatie is weer voor enige tijd verplaatst naar een mooi landgoed. Zou het daardoor echt beter gaan? Laten we het hopen. Maar of het nu in Den Haag of elders in het land gebeurt, waar het om gaat is dat er een stevige basis wordt gelegd voor goed bestuur in…
