TL;DR: In this article, electron paramagnetic resonance (EPR) spectra were used to study the properties of N-atom impurities in TiO2 under irradiation with visible light and showed that the Nb centers are responsible for visible light absorption with promotion of electrons from the localized N-impurity states to the conduction band or to electron scavengers.
Abstract: Nitrogen doped titanium dioxide is attracting a continuously increasing attention because of its potential as material for environmental photocatalysis In this paper we review experimental and theoretical work done on this system in our groups in recent years The analysis is largely based on electron paramagnetic resonance (EPR) spectra and on their interpretation based on high-level ab initio calculations N-doped anatase TiO2 contains thermally stable single N-atom impurities either as charged diamagnetic Nb- centers or as neutral paramagnetic Nb centers (b stays for bulk) The N-atoms can occupy both interstitial or substitutional positions in the solid, with some evidence for a preference for interstitial sites All types of Nb centers give rise to localized states in the band-gap of the oxide, thus accounting for the related reduction of absorption band edge The relative abundance of these species depends on the oxidation state of the solid In fact, upon reduction, oxygen vacancies form and transfer electrons from Ti3+ ions to the Nb with formation of Ti4+ and Nb- EPR spectra measured under irradiation show that the Nb centers are responsible for visible light absorption with promotion of electrons from the localized N-impurity states to the conduction band or to electron scavengers like O2 adsorbed on the surface These results provide an unambiguous characterization of the electronic states associated with N-impurities in TiO2 and a realistic picture of the processes occurring in the solid under irradiation with visible light

TL;DR: Understanding the neural bases of the non-conscious perception of emotional signals will clarify the phylogenetic continuity of emotion systems across species and the integration of cortical and subcortical activity in the human brain.
Abstract: Many emotional stimuli are processed without being consciously perceived. Recent evidence indicates that subcortical structures have a substantial role in this processing. These structures are part of a phylogenetically ancient pathway that has specific functional properties and that interacts with cortical processes. There is now increasing evidence that non-consciously perceived emotional stimuli induce distinct neurophysiological changes and influence behaviour towards the consciously perceived world. Understanding the neural bases of the non-conscious perception of emotional signals will clarify the phylogenetic continuity of emotion systems across species and the integration of cortical and subcortical activity in the human brain.
