With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

Phosphorylation affects all four major biomolecules – proteins, lipids, carbohydrates and nucleic acids – and plays a pivotal role in the most fundamental cellular functions.

Molecular materials have been a subject of interest in fundamental research and applications for decades, and have been studied as bulk crystals, (thin) films and as individual molecules, due to the large variety in their properties. This dissertation explores pentacene crystals near the two-dimensional…

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

This research delves into a region of space known as the interstellar medium (ISM), which is essentially the area between the stars filled with gas and dust.

Kan het gif van slangen, schorpioenen en andere dieren leiden tot nieuwe antibiotica?

The research described in this thesis has, using the zebrafish as a model system, shed new light on the intricate relationship between TB and DM2, in particular on the role of leptin, SHP-1 and glucocorticoids.

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

This thesis presents the first synthetic peptides ADP-ribosylated on serine, threonine, tyrosine, arginine and cysteine.

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

Een team van Leidse en Delftse studenten Life Science&Technology (LST), Nanoscience en Bio-informatica werkt hard aan een bacterie-estafetterace waarmee het de strijd aanbindt in de iGEM-competitie.

Pas sinds maart dit jaar werkt Sander Wezenberg in Leiden, maar hij heeft nu al een Vidi-beurs van NWO binnen weten te halen. Geïnspireerd door de natuur wil Wezenberg synthetische moleculen tot leven wekken en ze leren communiceren. Maar wie is Wezenberg precies en wat drijft hem?

An Active Galactic Nucleus (AGN) is a highly luminous region at the center of a galaxy, powered by the accretion into a supermassive black hole and emitting energy from radio waves to gamma rays, often outshining the host galaxy.

The explosive radiation and diversification of the advanced snakes (superfamily Colubroidea) was associated with changes in all aspects of the shared venom system. Morphological changes included the partitioning of the mixed ancestral glands into two discrete glands devoted for production of venom ormucous…
