A full overview of BPOC/SSNMR PhD theses.

At the largest scales, two ingredients dictate the distribution of matter in the Universe. The first is dark matter, acting as an invisible scaffolding held together by gravitational forces.

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.

The gas prices now exceed 300 euros per megawatt hour – a record. The transition from fossil (natural gas, coal, oil) to renewable energy is needed and soon. But how do you get a society (and its citizens) to switch to sustainable energy?

CML-researcher Rene Kleijn has spoken about metals scarcity in relation to the energy transition in a new Dutch popular scientific TV show called

A radical reduction in the amount of meat, dairy and other products sourced from animals is possible in the coming decades, as people turn to an increasing variety of alternatives. This would unlock vast amounts of land that we could use to produce energy and remove carbon from the atmosphere. Leiden…

HomininSpace is an agent based modelling and simulation system in which fluctuating carrying capacity is the key attractor for hominin dispersal. A parameterized and spatially explicit reconstructed palaeo-environment models available energy in the form of secondary biomass using reconstructed climate…

A century ago, it was unclear whether the stars in the sky were clustered in groups, or widely spread in the universe.

Decarbonizing the building stock is critical for realizing the climate-neutral target for the Netherlands.

A packaging-free shop, small mobile homes, solar panels on all Leiden's roofs… Jeroen Schrama, alumnus of Public Administration, is a creative world improver. ‘If we really want to save the world, we have to make much more radical choices.’

How can rare and expensive materials be used more efficiently to produce cleaner and cheaper fuel? Under the guidance of Marc Koper, Professor of Catalysis and Surface Chemistry, international teams of scientists have published 3 articles in Nature Communications.

The month of October saw LUGO host an active Green Morning to celebrate the opening of the largest green solar roof of the Benelux (located on the rooftop of the Snellius building!).

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

Over the past years it has been discovered that the population of extra-solar planets is large and diverse.

The west side of the campus square is occupied by the Lecture Hall, known as ‘the dish’. This building houses the largest lecture halls of Leiden University, which welcome hundreds of students every day. It also has Leiden’s largest solar panel roof, with 1241 solar panels.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

Greenhouse gasses in the atmosphere and fertilizers in the groundwater have negative consequences for our environment. With an electrochemical process they can be transformed to more valuable and useful substances like fuel and alcohol. Chemistry PhD candidate Elena Perez Gallent discovered how this…

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:…

Digitalisation can make a huge contribution to a greener future, but it must also be as sustainable as possible. To make significant progress, more collaboration and national leadership will be needed. Leiden University has therefore signed the Digital Sustainability Manifesto, which was presented on…

It’s become somewhat of a tradition at Leiden University: the strategic conference at the end of June each year. About a hundred staff including the faculty boards, academic directors, directors of the expertise centres and Administration and Central Services, the representative councils and student…

Can astronomers mitigate climate change? This is what Leiden astronomer Leonard Burtscher and his colleagues discussed at the annual meeting of the European Astronomical Society. For the second year in a row, the meeting was online. And according to Burtscher, it should stay that way. During a special…

Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…

Photosynthesis is the origin of life on earth, but it is a phenomenon that is still barely understood. Take, for example, the extremely efficient mechanism of electron transport. Leiden researchers demonstrate for the first time where one particular cause of this might be found.

Over 170 SUNRISE’s stakeholders gathered on June 17-18 at the Academy Palace of Brussels, in connection with the EU Sustainable Energy Week, as one of the Energy Days. Renewable energy experts from Academia, Industry and Policy addressed the current state of the initiative and its priority research…

Astronomers want to understand the Universe, from the Big Bang to the present day, and what the future will hold. In Leiden they focus on two key questions: ‘How did stars and planets originate’ and ‘How were galaxies and black holes formed in the young Universe?’ A new generation of telescopes – just…

How to contribute to a quantum leap of eco-industrial symbiosis in China?

Diverse types of exoplanets such as gas giants on close-in orbits (hot Jupiters) and young massive giants on wide orbits (super Jupiters), with no analogs in the Solar System, pose challenges but also opportunities to our understanding of planet formation and evolution.

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

For the first time, Leiden University has made it to the top 10 of the UI Green Metric, a global sustainability ranking for universities. Of the 780 participating universities, Leiden has taken seventh place.

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars (exoplanets). They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems. This way they address…

The first direct detection of gravitational waves opened the possibility of mapping the Universe via this new and independent messenger.

The thesis explores how interstellar chemistry evolves as a function of time and changing physical architectures during the formation of stars.

This thesis contributes to studying primordial cosmology theories and their detectability in future observations.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.
