I will give a general introduction to the field of molecular electronics, its history, methods and challenges. I will also introduce the subject of my investigation and provide a brief outlook to the remainder of our thesis.

Leiden Physicists have developed a new technique to visualize electrical conductance in sheet-like nano materials. It shows great promise for devices based on a new family of materials—the ‘Van der Waals materials’. The physicists, who won the 2015 Dutch Vacuum Society prize for their work, present…

This thesis presents the results of a study on the interfaces of insulating oxides with and without the insertion of a magnetic layer.

Solute carrier (SLC) transporters are a large and diverse class of relatively understudied transmembrane proteins.

The Leiden Institute of Chemistry (LIC) is to be joined by a further two talented young chemists. Bela Bode and Michele Pavanello have each won a Marie Curie subsidy. Bode will be studying electron transport in photosynthesis and Pavanello will be using computer models to study charge transport in large…

Majorana fermions in superconductors are the subgap quasiparticle excitations that are their own antiparticles.

Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

Multicellular giant algae Chara species have been widely used in physiological studies for decades.

How are carbohydrates processed by the immune system? Can carbohydrates be used to trigger T-cells against other conjugated antigens? Can they be used as adjuvants?

1. What is the exact role of PIN proteins in PAT? 2. How is PIN polarity established, and how is it modulated by AGC kinase-mediated phosphorylation? 3. What is the role of the AGC kinase, as modulators of PAT, in translating environmental signals, such as gravity, light or mechanical stress, to plant…

The availability of complete plant genome sequences together with the ever increasing amount of data on the molecular, cellular and physiological mechanisms of plant development require mathematical and computational models to obtain a complete overview of and generate new insights into the quantitative…

The PID-directed shift in PIN polarity has been broadly accepted as one of the essential mechanisms for the regulation of auxin transport polarity.

Relevant safety issues are associated with hazardous materials transportation, especially when transport routes cross populated areas. This article for the Journal of Loss Prevention in the Process of Industries analyses a 2015 accident with a freight train in Tilburg, comparing it to the Viareggio…

This thesis describes a study from both a theoreticaL and an experimental point of view.

What is the role of the rebound effect in achieving environmental savings from transport eco-innovation? Are traditional definitions of the rebound effect adequate in the context of transformative innovations and multidimensional environmental issues?

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.

In this thesis, classes of strongly interacting quantum field theories, have been studied.

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

Aviation safety is of global concern. Yet 43% of countries worldwide lack the expertise and administrative capacity to ensure effective safety oversight of the aviation activities for which they are responsible under international law.

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

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

Eco-innovations like more economical cars do not generate the environmental benefits predicted by the manufacturers. This is the result of the so-called rebound effect, concludes Leiden industrial ecologist David Font Vivanco on the basis of new algorithms. PhD defence 3 March.

The territories that would make up what is today the Republic of Zambia officially became British in 1891. However, this did not equate to an on-the-ground presence of colonial authority capable of affecting the destiny and daily lives of people.

Over the past decades within the European Union (EU), economic proliferation and globalisation have resulted in an increase in transboundary waste transportation. Although waste trading can often have positive economic and environmental impacts by repurposing natural resources within industrial sectors,…

Barend Barentsen, Professor Labour Law, talked about the local public transportation strikes in the Netherlands with Omroep Gelderland.

The quantum nature of matter and light has grown into a broad and fruitful research field for theorists and experimentalists alike. It combines foundational research with toward applications, the most well known of which is the quantum computer.

Leiden physicists found a surprising interaction between electrons and a resist layer. The resist appears to charge and discharge due to incoming electrons. Publication in Physical Review Letters.

On September 10th 2019 Bart Custers, professor of Law & Data Science at eLaw, was invited by the Committee for Infrastructure and Water Management of the Dutch parliament. In a round table discussion, this committee of the House of Representatives wanted to discuss the access to public transport data…

On 6 December 2022, the International Air Transport Association (IATA), which represents around 260 airlines in the world, released its Economic Outlook & State of the Industry, projecting that globally airlines would return to profit in 2023.

For one week, regional public transport drivers will go on strike. At least, that is what Dutch trade unions FNV and CNV are calling for. According to the employers’ association WVOV, half the busses will still be running.

Artificial photosynthesis has recognised potential to produce green and sustainable fuels from earth-abundant resources such as water, carbon dioxide (CO2), and sunlight.

In unconventional high temperature superconductors, supercurrent vortices are known to spoil the Landau levels. In this thesis the emergence of Landau levels is studied in different types of superconductors: Weyl superconductors, and the Fu-Kane heterostructure.

Meeting in person is crucial to higher education. It would therefore be inadvisable only to allow students to use public transport between 11:00 and 15:00. This is what the rectores magnifici of the Dutch universities say in a joint letter in ScienceGuide.

A novel mathematical model describes spatial-temporal drug distribution within one or more brain units, which are cubic representations of a piece of brain tissue with brain capillaries at the edges.
