When we study for the first time the structure of the atom in high school we encounter for the first time the concept of quantum excitation. We learn that excitation is the process in which a nucleus, electron, atom, ion, […]

Proteins were traditionally described as immobilized objects and classified according to the chemical composition (amino acid sequence) or the three-dimensional structure. However, in the seventies, with the idea that “If nothing can move, nothing can function”, Perutz first described the […]

Enediynes are organic compounds containing two triple bonds and one double bond. The enediyne groups in those compounds are often called warheads. Why this name? Because, many of these compounds are capable of undergoing Bergman cyclization or, in other […]

What is the closest two beryllium atoms in the electronic ground state can be in a molecule? Well, we may think that that is a relatively easy question to answer. If you know some chemistry it is likely you […]

An international team with the participation of the Center for Materials Physics in San Sebastián (CSIC-UPV/EHU) and Donostia International Physics Center (DIPC) have created the smallest lens in the world, capable to concentrate light down to dimensions of an atom. […]

Graphene nanoribbons (GNRs), are strips of graphene with ultra-thin width (<50 nm). Graphene ribbons were introduced as a theoretical model by Mitsutaka Fujita and coauthors to examine the edge and nanoscale size effect in graphene. GNRs are very interesting […]

The importance of water is paramount. Life, as we know it, would be unthinkable without it. Not only that, the geology of our planet, and those of other planets, can not be properly understood without a knowledge of how […]

Among the astonishing properties of graphene, a high mobility of the charge carriers has placed this material into the focus of intensive research efforts, aimed at developing high-speed graphene-based electronic devices. The first device of this family, a graphene […]

A chemical compound or molecule consisting of two identical simpler molecules is a dimer. If one of the simpler molecules is excited while the other is in its ground, non-excited, state we talk about excimers. They are excited dimers which […]

Everybody knows the force that is required to activate a light switch on a wall – a finger is enough. But how much force do you need to apply if the device was dramatically reduced to the “nanoscale world”, that […]
