The aim of this facility is to accelerate biomedical research by providing access to advanced light and electron microscopy and by sharing expertise about sample preparation, imaging modalities, data storage and image analysis.

The CMCB brings together a diverse range of unique expertise in microbial cell biology. Members of the CMCB investigate both model and non-model organisms, bacteria and archaea, pathogens and non-pathogens.

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.

With the powerful electron microscopes at NeCEN we study abnormalities in cells of blood vessels in cardiovascular disease, the interaction between pathogens and hosts in infectious diseases, molecular processes that cause cancer and the interaction between drugs and target proteins.

The principal aim of this research is to explore the confrontation between voice and electronics. These are often seen as being radically different from one another and many characteristics seem to be in opposition between them. However, they also have characteristics in common and they can influence…

This thesis revolves around the electronic spectroscopy of molecules in the laboratory and the search for the carriers of the diffuse interstellar bands (DIBs).

Materials with strongly correlated electrons show some of the most mysterious and exotic phases of quantum matter, such as unconventional superconductivity, quantum criticality and strange metal phase.

With tomography it is possible to reconstruct the interior of an object without destroying.

For the first time, physicists have visualized the ‘melting’ of electrons inside a special class of insulators. It allows electrons to move freely and turns the insulator into a metal and possibly later into a superconductor. Publication in Nature Physics.
