Green hydrogen is produced via a process called water electrolysis. During electrolysis water is split into oxygen and hydrogen.

Artificial photosynthesis aims to produce fuels from solar energy using chemical processes. In semi-artificial photosynthesis, a hybrid approach is taken using both chemical and biotechnology approaches. We aim to develop hybrid systems between light-harvesting nanoparticles and redox-enzymes (oxidoreductases)…

After studying Life Science and Technology, David Louwrier conducted his PhD research at LUCAS about bioart and societal debates around biotechnology. Now that his PhD thesis has been submitted, David is developing educational material about the societal aspects of the biobased economy.

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

The research that is united in the Liveable Planet programme, touches upon a wide range of aspects of human life. The goal is to deepen and expand the scope and to connect more researchers. The following case studies are examples of current research projects.

Are you engaged in society and interested in social issues? Study the Bachelor's in Public Administration in The Hague and learn how to analyse and solve complex challenges such as the housing crisis and energy transition, right in the administrative heart of the Netherlands.

Ludo Block wrote the eleventh chapter of the book 'Post-Crimea Shift in EU-Russia Relations: From Fostering Interdependence to Managing Vulnerabilities'. His chapter 'Business as Usual? Police Cooperation under a Cloud of Political Animosity' can be found on page 204 of the book.

Leiden has a strong tradition in theoretical physics, thoroughly linked with experimental disciplines.

Are you eager to dive into a cutting-edge approach to innovation? Do you want to explore how frugality and frugal innovation can drive sustainability? And are you up for an international, real-life challenge? If so, this Leiden-Delft-Erasmus (LDE) minor on frugal innovation is for you!

Can bacteria be engineered to convert methanol into valuable chemicals with high efficiency?

Understanding how nature captures and transfers solar energy is essential both for elucidating biological photosynthesis and for guiding the design of artificial light-harvesting systems.

The Europe Hub network currently spans over 60 researchers across 4 faculties at Leiden University. We especially foster thematic interfaculty research collaborations on a wide variety of societal challenges facing Europe. Here, you can read more about the four core thematic areas.

The adsorption of D2 and CO2 on catalyst surfaces is studied using a molecular beam in ultra-high vacuum.

The Leiden Science Run is a 5 km charity run at the Bio Science Park Leiden. It is a relay race organized by Leiden University in collaboration with the University Sports Centre.

Fearing a trade-off with economic growth, countries feel discouraged to cut their CO2 emissions. But do the two really not go together? Environmental scientist Ranran Wang and her colleagues investigated the relationship between economic growth and CO2 emissions in 73 countries from 1970 to 2016. Wang:…

Researchers at Leiden Observatory study the fundamental physics that creates structure in the Universe. These processes collect matter into galaxies and gas into stars. With the use of powerful telescopes and advanced calculations and computer simulations, Leiden astronomers seek to understand the origin,…

How might we include circularity into the models often used in IPCC reporting (in technical language, how can IAMs, dMFA models and CGE models be integrated?) What are possible futures for global resource use and what are the consequences for greenhouse gas emissions in these scenarios?

An accurate description of reactive scattering of molecules on metal surfaces often requires the modeling of energy transfer between the molecule and the surface phonons. Although ab initio molecular dynamics (AIMD) can describe this energy transfer, AIMD is at present untractable for reactions with…

Photocatalysis has emerged as a powerful tool for enabling challenging transformations in organic synthesis. This thesis explores the development of several photocatalytic reactions designed to form carbon-heteroatom bonds from less-functionalized precursors.

The electrochemical hydrogenation reaction is an alternative approach for the transformation of unsaturated bonds without the use of flammable dihydrogen gas.

This thesis highlights the significant role of surface geometry and oxidation state in determining CO adsorption behavior on copper surfaces.
