The electrochemical oxygen reduction reaction (ORR) is an essential half-reaction for the utilization of hydrogen as a sustainable fuel, via the conversion of hydrogen to electrons and protons facilitated by the ORR. In the most common fuel cells, the ORR is requires high loadings of non-abundant platinum…

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…

Leiden University Library holds two drawings and in the region of a hundred prints by Rembrandt, as well as works by his pupils and the staff of his studio. That explains why this self-portrait etching dating from 1631, his Leiden period, can be seen on the façade of the University Library.

Jasper de Bruin, Guus Besuijen, Hans Siemons & Jeroen van Zoolingen (2012). De romeinse nederzetting bij het tegenwoordige Goedereede heeft waarschijnlijk een belangrijke functie gehad in de overslag en distributie van diverse goederen, waaronder keramiek en voedingsgewassen. De opgraving van deze nederzetting…

For three millennia, carved sculptures were ubiquitous among ancient peoples in the Americas. Sculpted in stone, metal or wood, they developed into the well-known totem poles, colossal Olmec heads, royal Maya stelae and golden Inca statues.

1) Assess the trends in supply and production status of these critical minerals and mineral products worldwide and Europe’s dependence including on intermediate products such as permanent magnets, RE based super alloys, batteries, polishing compounds, phosphors, catalysts etc. 2) Trace the entire value…

This project aims to further understand the molecular details related to the biosynthesis and function of Galf containing glycoconjugates in fungal Aspergillus spp.

How do nanoparticles bioaccumulate and biodistribute in organisms?

In 2013, Sylvestre Bonnet received an ERC Starting Grant to kill cancer with molecules that can be activated by light. Two postdocs and three PhD students later, the end approaches of his so far successful project.

A catalyst: normally a substance that speeds up a chemical reaction, without adding molecules to this reaction. Scientists from the group of Prof. Marc Koper of Leiden University and Prof. Yang Shao-Horn of MIT now discovered that in specific reactions that need oxygen, catalysts called metal oxides…

On Thursday November 15th, Leiden University organizes its Physics & Astronomy Ladies' Day for female high school students. To mark this festive day, we put the spotlight on five female researchers, who talk about their experiences working in science.

The Hydrogen network brings together leading researchers from different disciplines and sectors with a combined expertise that maximises the chance of achieving scientific breakthroughs in production and storage of hydrogen, while guaranteeing the successful training of a new generation of scientists…

As a venue, Leiden University is a fitting setting for recognising the outstanding achievements of the award winners and celebrating the inspiration that they bring as role models for encouraging a fairer society by motivating one individual at a time.

Lecture

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…

Leiden physicists use a new method to measure so-called surface plasmons. Researching these particles could lead to new light-based technology, including faster internet.

Measurements on a superconducting material show an abrupt transition between a normal metal and a 'strange' metal. The really strange thing, however, is that this abruptness disappears when the temperature falls. 'We don't have any theoretical machinery for this', says theoretical physicist Jan Zaanen,…

Using N2 dissociation on Ru(0001) as a representative showcase (for catalysts employed in the Haber-Bosch process), we have shown for the first time that non-adiabatic effects can substantially reduce a molecule’s dissociation probability on a metal surface. These effects are currently completely unaccounted…

Situated on the west coast of modern Turkey, the site of Ephesus is one of the largest excavations in Turkey and one of the most visited tourist attractions. Only one tenth of the city has been exposed until now although the Austrian Archaeological Institute in Vienna (ÖAI) has been excavating here…

The project’s main aim was to build a reconstruction of a prehistoric house plan, without using any metal tools. How effective are tools made of stone, flint, bone, antler and wood? What are the constraints imposed by the various building materials? How much labour do we need and how much knowledge…
