Quantum critical metals at vanishing fermion flavor number.

The current production of a number of critical metals is insufficient for the large-scale transition to electric vehicles. This is the conclusion of a report by environmental scientist Benjamin Sprecher and organisations Copper8 and Metabolic. As a solution, they advocate more electric car-sharing,…

Accumulation of metals in economy and environment and its associated risks, within the Netherlands and the EU.

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…

Can we provide the Dutch government with an integrative framework, wherein the various policies can be placed and the need for further measures can be identified?

Central in coordination and organometallic chemistry is the synthesis of new chelating ligands, the synthesis and characterization of metal complexes with these ligands, and the study of their properties. An important goal in my research is to create understanding of the relation between the structures…

Galaxies are environments where gas coalesces, cools, and is converted into stars. However, it remains unclear the exact mechanisms through which galaxies acquire, redistribute and lose their gas.

The dissociative chemisorption of a molecule on a transition metal surface represents a rate-limiting step in many heterogeneously catalyzed processes, whereby most chemicals are made. In spite of the importance of this reaction, an accurate first principles approach to modeling it does not yet exist.…

The aim is to discover where differently shaped metal nanoparticles distributes in Danio rerio, linking the distribution with genomic responses and so come up with a Mode of Action.

Coordination chemistry is the chemistry of metal atoms

In the last decade, the redox interconversion between metal thiolate and disulfide compounds has been extensively investigated for copper, but not for other transition metal ions.

In-use stocks of products can be considered as intermediaries between human needs and the physical world.

We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

The Heritage Sector at a Crossroads: The way of Intersectionality. This project investigates how heritage institutions can achieve inclusion and accessibility within their organization, collection, and exhibition spaces that meets the breadth of demands placed by today’s “critical visitors.” Fifteen…

It is estimated that approximately 30% of all proteins require a metal to function. Investigating the relationship between metal-binding and peptide/protein folding allows us to uncover fundamental rules for creating metallo-peptides and proteins, which in turn leads to the creation of new structures,…

This thesis aimed to investigate the impact of exposure dynamics, relative contributions of ENPs(particle) and ENPs(ion), and dosing regimens on the toxicity of ENPs varying in different physico-chemical properties, on the composition and functioning of soil microbial communities.

This thesis focuses on the synthesis, characterization and performance towards CO2 electroreduction of mono and bi-metallic particles based on p-block metals

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

The rapidly increasing commercial application of metallic nanoparticles within products will inevitably enhance the amount of NPs being released into soil.

The research described in this thesis focused on the preparation of S/N functionalized carbene ligands and their transition metal complexes, and the exploration of their application as electrocatalysts for proton reduction.

Conference

Leiden Centre for Continental Philosophy is pleased to announce a symposium called: 'Critical Phenomenologies. The intertwinement of structural inequities and embodied experience.'

This research focuses on the (Quantum) Dynamics (QD) of the reactive scattering of H2 from metal surfaces.

Describe and identify what dosimetry parameters are of importance to interpret dose-response relationships (eg., mortality, sub-lethal, growth or reproduction inhabitation, DNA damage and reactive oxygen species, etc. ) for metal-based nanoparticles? How to develop quantitative models that enable to…

Leiden University and VU Amsterdam are developing a joint research project for a digital platform on which you can compose and share storylines with the use of images. Such interactivity will make a boring high school history lesson much more exciting and personalized. Furthermore, it will stimulate…

These four volumes offer students and researchers a rich collection of published works on the history of slavery works by some of the most preeminent scholars in the field.

Doctoral research on recent developments in museological practices by “critical” curators, interventionist artists, and personnel initiatives, focusing on ‘queering’ as an entrance point to broader intersectional issues; resulting in a report on the ‘Queer Baseline’ (to be launched in 2020), a popular…

Mathilde Mechling defended her thesis on 28 january 2020.

In the fall of 2021, Cleveringa professor Roméo Dallaire and world experts shared their thoughts about PTSD, children’s rights, war crimes, humanitarian law, and peacekeeping in a series of conversations about leadership and moral dilemma during times of conflict and crisis.

The study by Tahir Abbas and Liselotte Welten reveals a structural and nuanced understanding of how the question of Salafism in the Netherlands has become an increasingly discussed phenomenon and the types of threats that ought to give genuine concern to security, intelligence and policing services.

How can the concept of Critical Making be expanded into a general approach that ties the critical methodology of artistic research, and the established concepts of artistic autonomy, together with contemporary creative-technological development?
