In the Aarts lab we combine or structure materials, mostly in thin film form, in such a way that the hybrid has different and novel properties or functionalities.

Pharmacologist Amanda Foks is one of the ten talented scientists who received a Dekker grant from the Hartstichting. She receives €427,000 to find a way to rejuvenate immune cells to prevent infarcts. Foks was nominated as Discoverer of the Year in 2016.

This thesis investigates reactive interfaces in surface science across three domains: heterogeneous catalysis, environmental nanoplastics, and two-dimensional materials.

State Secretary Sander Dekker of Education, Culture and Science received the national research agenda Nature4Life on 31 January. This research agenda, in which Leiden University is involved, focuses on research on biodiversity, ecology and evolution.

Over the past century, the world population has grown exponentially, as has our need for energy and raw materials. If we wish to continue to live prosperously in the future, we have to radically restructure our economy and consumption. Scientific research shows us how to do this.

Perception of material culture, design and digital knowledge applications

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…

The Faculty of Archaeology's own home-grown journal Inter-Section has released a new volume. Inter-Section offers students and PhD candidates the unique chance to publish in a peer-reviewed journal. The new volume focuses on the materials that shape our world.

RAWCLIC’s main goal is to develop knowledge on the future raw materials (RMs) demand, supply and associated environmental impacts induced by the energy and digital transitions in the EU, and to support fact-based industry- and policy- decision-making enabling these transitions.

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…

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

Promotor: E. Bouwman, Co-Promotor: S. Bonnet

The group of Dr. Roxanne Kieltyka designs and synthesizes molecules that self-assemble into polymeric materials using specific non-covalent interactions. These substrates can be used for numerous applications in medicine ranging from disease detection to cell delivery depending on the (bio)molecular…

The identification of the material of prehistoric arrowheads as human bone led to interest from the media. Research Master's student Jan Dekker, the principal researcher, was interviewed by NewScientist, Smithsonian Magazine, and several Dutch news agencies.

The goal is to develop educational materials for Dâw, Hupd’äh, and Nadëb Indigenous peoples (Naduhup family; Middle and Upper Rio Negro; Brazilian Amazon). In order to achieve this, first of all, the fieldwork data collected during a collaborative project among anthropologists and linguists (2017-2020)…

In our lab, we investigate the physics and material properties of low-dimensional systems.

Coordination chemistry is the chemistry of metal atoms

This thesis focuses on developing wafer-scale two-dimensional (2D) materials by combining synthesis, transfer, characterization, and device integration of graphene, hexagonal boron nitride (h-BN), and BN-doped amorphous carbon.

Innovating objects in a Eurasian center of the Late Hellenistic period.

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.

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.

1) The in-use construction material stocks of the BRI projects and their temporal and spatial distribution. 2) Environmental impacts (e.g. carbon emission and biodiversity loss) of constructing BRI projects. 3) Socio-cultural impacts of the BRI projects.

NTER-SECTION is a peer-reviewed, open-access journal focusing on contributions from junior archaeological researchers at Leiden University. The journal offers an accessible platform for the publication of individual research by undergraduate and graduate students. The Editorial Board consists of PhD…

On Wednesday morning, 14 March, Sander Dekker, Minister for Legal Protection, gave a guest lecture to the students of the Master Crisis and Security Management as part of the course Crisis Management. Dr. Sanneke Kuipers presented propositions based on theory to Minister Dekker. After each proposition,…

How can the Safe and Sustainable by Design (SSbD) framework developed in the SSbD4CheM project facilitate the creation of safer and more sustainable chemicals and materials across various industries?

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.

This project examines the notion of sacred fertility and sacred landscapes, associated rituals and material culture, both archaeological and ethnographic manifestations in the Horn of Africa.

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.
