Theorists have recently made substantial progress in simulating reactive molecule-metal surface scattering but still face major challenges. The grand challenge is to develop an approach that enables accurate predictive calculations of reactions involving electronically excited states with potential…

Nonadiabatic energy transfer from the translational motion (T) of a molecule impinging on metal surface to the metal’s electrons may determine whether the molecule can lose enough energy to adsorb or react.

In most applications, electrocatalysts exhibit a large surface area to volume ratio, for example using nanoparticles.

It's pretty hard to spot a single 5 nanometer particle. Leiden physicists pulled it off by turning a 120 nm gold rod into a detector.

We, as LUGO, believe that with simple everyday actions we can prevent large amounts of single-use plastic water bottles from entering our oceans.

The “harpe organisée”, 1720-1840: Rediscovering the lost pedal techniques on harps with a single-action pedal mechanism, is the title of Maria Christina Cleary's PhD thesis. This is the first monographic study on harp pedal techniques, tracing the historical way to pedal on the early pedal harps with…

The way genes are folded determines their activity in our body. Leiden biophysicists are now the first to unravel this structure molecule-by-molecule. Publication on December 1st in Nature’s Scientific Reports.

Light can be used to apply forces on single cells. Focused lasers have been used by physicists to tweeze particles and to manipulate them. These so called “optical tweezers” can be used as mechanical phenotyping tools for characterising the mechanics of materials and living objects.

Leiden physicists have managed to detect a single molecule called dibenzoterrylene in a new crystal, and found that it is a candidate component for a quantum network. Future quantum computers will need such a network to work together while maintaining their advantages. Publication in ChemPhysChem jo…

In this thesis, the focus lies on studying glucocorticoid receptor dynamics in living cells with the aim of understanding how this transcription factor finds its DNA target sites to regulate transcription.

Viral hemorrhagic fever (VHF) is a group of acute diseases caused by highly infectious viruses including Ebola, Lassa, Dengue viruses. Its high mortality rate poses high risk to public health, however, studies on VHF have been hampered due to the non-availability of proper models and incomplete knowledge…

Apart from his activities as coordinator of the Academy of Creative and Performing Arts, Rogier Schneemann is co-founder, guitarist and composer of the Dutch-Italian group Azure Hiptronics, originally formed in 2006.

A group of single-celled organisms organises its DNA in a similar way to higher organisms such as plants, animals, and fungi. However, the way packaged DNA is read out differs between the two related groups, Bram Henneman discovered. PhD defence on 5 December.

Individual molecules are extremely hard to see through feeble fluorescence. Tiny gold nanorods serve as new antennas to intensify their signal 500 times. Publication on 24 February in Angewandte Chemie.

Single-celled organisms have stiffer DNA than multicellular lifeforms like humans and rice. Theoretical physicists managed to simulate the folding in full genomes for the first time to reach this conclusion. Publication in Biophysical Journal on February 7.

Ferritin is a spherical metalloprotein, capable of storing and releasing iron in a controllable way. It is composed of a protein shell of about 12 nm and within its cavity, iron is stored in a mineral form.

Dear friends of the NVIC

During my PhD research, I studied the photon statistics of light emitted by a microcavity that contains a single quantum dot (QD) on resonance.

Paleobotanist Menno Booi discovered that 250 previously described fossil tree species are objectively not distinguishable; they belong to only one single species.

Healthy aging is one of the prime goals in today's society and atherosclerosis is among the greatest causes of morbidity in elderly. Cardiovascular disease patients receiving treatment are often of advanced aged and have an aged immune system, which limits translating experimental findings to the pa…

Chemical reactions go hand-in-hand with an energy exchange with the environment in which they take place. Surfaces offer a variety of energy dissipation channels, constituted by the nuclear and electronic degrees of freedom of the atoms at the interface. Aiming at an improved future harvesting of energy,…

Michiel Hogerheijde has been appointed temporary programme director of the Astronomy master's programme from 1 January to 1 September 2024. He takes over the duties of Harold Linnartz, who unexpectedly passed away at the end of December. Hogerheijde combines the position with his duties as programme…

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

All life on earth contains DNA, which is used to store biological information. Organisms compact their DNA in order for it to fit inside their cell(s).

Heterogeneous catalysis is essential to many industrial applications. These catalysts are often comprised of supported nanoparticles, which contain various different surface sites.

The research presented in this thesis makes use of small molecules (as H2 , D2 and O2 ) on well-defined single crystal surfaces (flat Pt(111), flat Cu(211) and curved Pt(111)) to elucidate the role of surface structure and degrees of freedom in the reactant in specific surface reactions.
