Cathodic corrosion is a relatively unknown phenomenon that can severely etch metallic electrodes at cathodic (negative) potentials.

Cathodic corrosion for producing nanoparticles was (re)discovered when trying to control the electrochemical etching of a scanning tunneling microscopy (STM) tip.

An indian stepwell on a nanoscale. That is what postdoc Nakkiran Arulmozhi calls the pattern he saw when he corroded a special kind of platinum crystal. The unique images show the destructiveness of the process, but also show how predictable it is.

This work describes several studies into the electroreduction of carbon dioxide (CO2RR), both regarding mechanistical aspects and catalyst stability considerations. Mechanistic insights into carbon-carbon bond formation on a silver catalyst are described in Ch 2, were we find an acetaldehyde-like surface…

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.

This dissertation explores how Large Language Models (LLMs) can effectively and responsibly contribute to complex decision-making processes. By combining AI and human intelligence, Hybrid Intelligence (HI) emerges, allowing the strengths of both humans and machines to be utilized.

This dissertation advances automated negotiation by developing agents that can learn and adapt across diverse negotiation settings through three increasingly sophisticated approaches: automated algorithm configuration, portfolio-based strategy selection, and end-to-end reinforcement learning with graph…

Tin electrodeposition applications have rapidly evolved in the past 25 years.

Leiden University has developed a radically different method for large scale production of diverse nanoparticles and their alloys.

Hybrid Intelligence (HI) is the combination of human and machine intelligence, expanding human intellect instead of replacing it. HI takes human expertise and intentionality into account when making meaningful decisions and perform appropriate actions, together with ethical, legal and societal values.…

From surface science towards industrial practice using high-pressure scanning tunneling microscopy.

On 18 April, Alexandre Tavadian defended the thesis 'The International Civil Service: Redefining Its Independence'. The doctoral research was supervised by Niels Blokker and Brian McGarry.

The central theme of Rik Mom’s research group is to identify what the electrode-electrolyte interface looks like when electrocatalysis is taking place. Using specialized forms of Raman and X-ray spectroscopy, we study the chemical state and bonding environment of the electrode surface and near-surface…

Some examples of AI-research done at Leiden.

The Dick Stufkens Prize 2019 for the best PhD thesis of the Holland Research School of Molecular Chemistry (HRSMC) will be awarded to Thom Hersbach. In his thesis, Hersbach presents a thorough analysis of cathodic corrosion. His comprehensive research, on which he graduated with the distinction cum…

An overview of awards and prizes granted to our staff and students in 2019, as well as special appointments and royal distinctions.

The aim of ANCIENT CHARM was to develop neutron-imaging techniques and the associated equipment, and help establish neutron imaging as a mainstream archaeological analytical technique. In particular, one of the goals was a new imaging technique which called neutron resonant capture imaging combined…

Both Leon Jacobse and Thom Hersbach from Marc Koper's research group obtained their PhDs cum laude. They both investigated changes on the surface of a platinum electrode. Jacobse studied this at a positive voltage, Hersbach at a negative voltage. Platinum has the potential to convert renewable energy…

Human AI is where artificial intelligence and machine learning meet philosophy, cognitive science, and the creative arts. Examples of research questions in this domain are: 'Can an algorithm be creative by human standards?', 'Can creative processes, such as composing music or writing poetry, be modelled?',…

SAILS likes to occasionally organise workshops about topics that relate to our programme. On this page you can find more information about previous workshops.

Intelligent machines are going to make ethical decisions too. Should a self-driving car be allowed to slam into pedestrians to save its passengers from a head-on collision? Should a negotiation app be able to detect stress in your opponent’s voice? And who makes these decisions: the user, the system’s…

On October 14, the first symposium of the university-wide initiative SAILS took place. Scientists from Leiden University and other Dutch universities came together to share their enthusiasm and expertise in the field of Artificial Intelligence in a festive symposium, in the atmospheric Museum of Eth…

Past objects offer a wealth of information about life in earlier times. Loe Jacobs is an expert in making earthenware objects, using the same methods and means used in earlier times.

The Secular Outlook describes what moral and political secularism means. It paints the image of a world view in which state and religion are kept well separated.

Computers are capable of making incredibly accurate predictions on the basis of machine learning. In other words, these computers can learn without intervention once they have been pre-programmed by humans. At LIACS, we explore and push the borders of what a revolutionary new generation of algorithms…

Leiden University, Delft University of Technology and Erasmus University Rotterdam are important players in the world of self-learning machines that can work together with people. Moreover, the three have close ties in the field of AI and hope to further strengthen this collaboration in the future.…

Marie Curie once said: I have no dress except the one I wear every day. If you are going to be kind enough to give me one, please let it be practical and dark so that I can put it on afterwards to go to the laboratory.

Water damage, old restorations and copper corrosion in some illustrations. De Materia Medica has been through a lot over the centuries. The manuscript dates from 1083 AD and is one of the oldest illustrated Arabic manuscripts in the world. Due to intensive use, De Materia Medica was no longer in good…

In 2022, many of our staff and students won fantastic prizes and were awarded important research grants.

Artificial Intelligence is likely to have far-reaching consequences for all actors in the realm of academic publishing, including authors, editors, researchers, and readers. This symposium aims to foster the conversation about the various ways in which we evaluate, enrich, and disseminate academic knowledge,…

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.

Leiden University is involved in five new NWO Gravitation projects. Two relate to mental disorder and the remaining three to a healthy lifestyle, the combination of human and artificial intelligence, and the special relationship between plants and microbes.

Lecture

‘Our health is the area that stands to gain most from artificial intelligence.’ The three universities in Zuid-Holland are helping make these gains. Three researchers talk about their collaborative research into AI for health, drug discovery and healthcare in the AI knowledge cluster in Zuid-Holland.…

Disinformation has become a popular subject of study and debate. A plethora of publications and policies have emerged, aiming to analyse and curb the negative consequences of unwanted communication.
