CERA (CErtification of RAw Materials) is a four-year project that will develop a standardized certification scheme ensuring environmental, social and economic sustainability in extraction, processing, trading and manufacturing of all mineral raw materials. It will guarantee traceability of certified…

Where and how are critical materials currently used and how can this information be used to develop scenarios about their future demand.

Wat is mechanica van zachte materialen (o.a. schuim, zand)?

Can we develop a platform for raw materials intelligence?

A sustainable resource management is an essential aspect to satisfy the current human needs without compromising the needs of future generations.

Examining if large scale application of new energy pathways can be constrained by materials and emissions.

De wereldbevolking is in de afgelopen eeuw exponentieel gegroeid, en daarmee ook onze behoefte aan energie en materialen. Willen we in de toekomst ook in welvaart leven, dan zullen we onze economie en consumptie radicaal anders moeten inrichten. Wetenschappelijk onderzoek laat zien hoe dat kan.

Geometric phases lead to a nontrivial interference result when an electron's different quantum mechanical paths choices encircle a magnetic coil in an Aharonov-Bohm experiment.

The expanding population and economic activity are driving up global energy consumption. Simultaneously, there is an urgent need to transition from fossil fuels to renewable sources to mitigate the climate crisis, primarily caused by fossil fuel combustion.

An account of the total of material flows going in, out and through Amsterdam.

How can prospective LCA be streamlined in a way that its practical application in research and technology development increases?

Some examples of research questions include: What framework of circular strategies should local practitioners use? How should practitioners organize their monitoring of the circular economy activities in the region of interest? What are the main products that have the most circular potential in the…

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…

The role of material production as a driver of environmental impacts is increasing, which calls for a better understanding of global material flows. This thesis explores the role of in-use stocks of products, buildings and infrastructure as a key driver of global material demand and discusses the implications…

This dissertation investigates the energy and material related impacts of the transition towards a low-carbon heating system in the Netherlands, in the context of its 2050 climate and circular economy policy goals.

Self-assembly is an abundant process in nature and is vital to many processes in living organisms.

In this thesis, time-lapse fluorescent microscopy plays a pivotal role in investigating functional materials within living cells as well as the migratory behaviour of neural progenitor cells.

1) Assess the trends in supply and production status of these critical minerals and mineral products worldwide and Europe’s dependence including on intermediate products such as permanent magnets, RE based super alloys, batteries, polishing compounds, phosphors, catalysts etc. 2) Trace the entire value…

The studies in this thesis are focused on the physical effects in the flat band materials. The results contain the discovery of strong enhancement of RKKY spin-spin interactions with specific geometric arrangement and dynamical generation of excitonic order parameter with high magnitude.

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

What are the flows of C&DW (e.g. bricks, concrete, gypsum and wood) in the case study countries ? How to define the specification for each material to be quantified? What indicators should be used to identify the pattern of each C&DW management system? How to interpret the MFA results in relation…

In the current global context, there is a pressing need to address sustainable energy supplies to safeguard our Planet and its ecosystems. The choices made by human society have a significant impact on genetic evolution and climate.

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.

Minister Dekker kondigde een wetsvoorstel aan om de voorwaardelijke invrijheidsstelling aan te passen. Nu komen gedetineerden in aanmerking voor vrijlating na tweederde van hun straf. Als het aan Dekker ligt wordt die periode maximaal 2 jaar. Pauline Schuyt denkt dat deze wet alleen maar verliezers…

Ter herinnering aan de Leidse (ESO-)vergadering van het eerste uur onthult staatssecretaris Sander Dekker in het Academiegebouw van de Universiteit Leiden een plaquette op dinsdag 3 maart.
