One of the multiple tasks of quantum chemistry is the rationalization of the bonding between atoms to form molecules. In this vein, two main aspects are clearly distinguished: i) the binding energy, or the energy gained by the molecule when two atoms are bonded; and ii) the bond order (how many bonds are the responsible […]
Scientific experiments using animals frequently involve the marking of animals that artificially changes their phenotype. For instance, penguins with flipper bands have been used to study climate change. However, as Saraux et al. show, this banding reduces penguins’ survival rate. Consequently the study may mix up the effects of banding with other changes in penguin […]
The wave nature of light expresses itself in the propagation all over space, showing an intrinsic limitation to be localized beyond the so-called diffraction limit which is of the order of half the wavelength of the photons propagating. However when interacting with matter, light often gets reflected, diffracted, scattered or absorbed depending on the interactions […]
