The roughening of a platinum electrode
Smooth platinum electrodes roughen and wear when subjected to repeated cycles of oxidation and reduction, which causes nanometer-scale mounds to grow. Leiden chemists Leon Jacobse and Marc Koper, together with physicist Marcel Rost, discovered the exact details, using a unique tunneling microscope.

Lowlands as lab: virtual trips in the name of science
While tens of thousands of visitors dance to deafening music, a team of Leiden psychologists are trying to collect data for their research at Lowlands. How do festivalgoers experience a virtual trip? And what role do factors such as too little sleep and whether they have experience with psychedelics…

Experience one hundred years of astronomy at the Old Observatory
How big is the universe? How do stars form and evolve? And does life exist elsewhere in the Universe? These main questions in astronomy are the themes of the new exhibition Above & Beyond, which was created in honour of the hundredth anniversary of the International Astronomical Union (IAU). The exhibition…

New technique for Imaging Charge Transport in a Graphene Layered Cake
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…

The magic of liquid helium: this person makes ice-cold research in Leiden possible
White clouds of ice-cold gas flowing across the floor. Magical, but be careful not to freeze your fingers off. We are of course talking about liquid nitrogen and helium. You may have seen the spectacular Freezing Physics science show by the student organisation Rino. But did you know that this commodity…

Third time's a charm: ERC Advanced Grant for Marc Koper
Electrochemist Marc Koper has been awarded an ERC Advanced Grant of 2.5 million euros for research into chemical reactions driven by electrodes and electricity. He hopes that new insights will make it into the textbooks and help design green processes, such as making fuel from greenhouse gas.

ERC Advanced Grant for Carlo Beenakker to ‘braid’ Majorana fermions
Theoretical physicist Carlo Beenakker has been awarded a €2m Advanced Grant by the European Research Council (ERC). He will use this to try to create the ideal building blocks for a quantum computer: ‘braided’ Majorana fermions. An ambitious project that may just lead to a major breakthrough.

Two cum laude distinctions for storing renewable energy
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…

Assessing total environmental impact is becoming even more important
Life cycle assessment (LCA) reveals the total environmental impact of products or production processes, and EU rules are going to make this even more important.

The healing power of light
Light makes us flourish – in this respect we humans are just like a rose or an azalea. Light can also be used to treat people who are ill. In Leiden, Sylvestre Bonnet and Esther Habers are working – each in their own discipline – on new applications of light in a clinical context.

Leiden physicists image lumpy superconductor
High-temperature superconductivity is one of the big mysteries in physics. Milan Allan’s research group used a Josephson Scanning Tunneling Microscope to image spatial variations of superconducting particles for the first time, and published about it in the journal Nature.

Four Leiden Scientists: 'Environmental risks of new pesticides with nanoparticles insufficiently examined'
The environmental risks of new pesticides containing nanoparticles are inadequately researched, according to four Leiden scientists in the scientific journal Environmental Science & Technology. They call for an examination of the long-term and environmental effects of pesticides containing nanoparti…

PhD Research || Re-discovery of the Italian salterio
It was her original Salterio from 1725, built by Michele Barbi, which Franziska Fleischanderl could coincidentally acquire in 2014 that ignited her passion for this special string instrument. Before, she was focussed on contemporary music with modern Hackbrett.

The quest for the magic angle
Stack two layers of graphene, twisted at slightly different angles to each other, and the material spontaneously becomes a superconductor. Science still can't explain how something so magical can happen, but physicists use special equipment to reveal what is taking place under the surface.

How a Dutchman contributed to the rapid development of Singapore
In 1960, Albert Winsemius started to help the city state of Singapore achieve its rapid rise out of economic misery. He helped the Singaporean government understand how the Netherlands had managed to rebuild so quickly after the Second World War, with the help of the American Marshall Plan. PhD defence…

John Mydosh and the mystery of the Hidden Order
A 35-year-old uranium crystal will not disclose its secret: what causes a dramatic phase transition at 17.5 Kelvin? Thanks to a new artificial intelligence approach, half of the possible explanations are excluded, but the definitive answer remains to be found. 'It is very frustrating', says physicist…
