Importance of surface oxygen vacancies for ultrafast hot carrier relaxation and transport in Cu_{2}O

Physical Review Research, Vol 3, Iss 4, p 043219 (2021)
Cu_{2}O has appealing properties as an electrode for photoelectrochemical water splitting, yet its practical performance is severely limited by inefficient charge extraction at the interface. Using hybrid DFT calculations, we investigate carrier capt

Defect chemistry, strain, and structural, magnetic, and electronic degrees of freedom constitute a rich space for the design of functional properties in transition-metal oxides. Here, we show that it is possible to engineer polarity and ferroelectric

In this study, we investigated whether the relative abundance of glutamate and glutamine in human proteins reflects the availability of these amino acids (AAs) dictated by the cellular context. In particular, because hypoxia increases the conversion

Notwithstanding the huge amount of detailed information available in protein databases, it is not possible to automatically download a list of proteins ordered by the position of their codifying gene. This order becomes crucial when analyzing common

The functional properties of transition metal perovskite oxides are known to result from a complex interplay of magnetism, polarization, strain, and stoichiometry. Here, we show that for materials with a cooperative Jahn-Teller distortion, such as La

Contradictory theoretical results for oxygen vacancies in SrTiO_{3} (STO) were often related to the peculiar properties of STO, which is a d^{0} transition metal oxide with mixed ionic-covalent bonding. Here, we apply, for the first time, density fun

Perovskite oxides are an extremely versatile class of materials in which functionality can, besides other routes, also be engineered via the deliberate introduction of defects. In this focused review, we will specifically look at mechanistic details

The functional properties of metal oxide semiconductors depend on intrinsic and extrinsic defects. The population of intrinsic defects is strongly affected by the synthesis method and subsequent treatments of the material, while extrinsic defects can

Vitamin D and TGF-β exert opposite effects on epithelial-mesenchymal EMT transition. Here we report a novel mechanism of action of TGF-β that promotes the counteracting activity of vitamin D; in two models of human epithelial-mesenchymal EMT transi
