A quantum dot is a nanometric crystalline structure of semiconductor materials. In a quatum dot electrons are confined in a region of space, thus creating a well defined structure of energy levels that depends very much on the size and […]
Imagine a military regiment in formation. That we will call symmetry. Now imagine the same regiment when it is dismissed by the commanding officer: at once the soldiers disperse and tend to form domains (groups) or pairs. Hence, we can […]
Author: Mónica Carril is an Ikerbasque Research Associate at the Biophysics Institute CSIC-UPV/EHU.
When nanoparticles (NPs) get in contact with biological fluids such as blood, proteins present in it will adsorb on the surface of those NPs forming what is […]

Few materials have drawn as much attention as graphene, it fascinating attributes such as one-atom thickness and relativistic electrons, and its technological properties […]
Mobile phones and computers are currently responsible for up to 8% of the electricity use in the world. This figure has been doubling each past decade but nothing prevents it from skyrocketing in the future. Unless we find a way […]
The ability to examine the vibrational spectra of liquids with nanometer spatial resolution will greatly expand the potential to study liquids and liquid interfaces. After all, modern technology, including many manufacturing processes, and science depend on understanding the detailed interactions […]
“What would happen if we could arrange the atoms one by one the way we want them?” Richard Feynman
Fabrication of matter atom by atom remains a long-standing dream and ultimate goal of nanotechnology, following the famous challenge by Feynman […]
Imagine that we have a conductor or a semiconductor through which a current is flowing. Then we apply a strong transverse magnetic field. As a result, we can measure a potential difference at right angles to both the current and […]
Chemists have a range of different spectroscopic techniques to study organic molecules. All of these techniques are based on spectra generated by a range of electronic transitions and vibrations, key excitations in matter, the study of which provides information about […]
The properties of bismuth have long defied classification, placing it in a category of its own. Now, as if it was not enough, it turns out its electronic structure has higher-order topology. This has been shown by an international team […]
