This study explores the intricate chemical processes at the interface between the topological insulator BiSe and deposited Au. The study mainly focused on room-temperature interactions that can cause the aging of, e.g.

We describe the use of 10 prioritised WHO-Standard-based Quality Measures to assess QOC for children with acute diarrhoea (AD) in Italy.
Methods: In a multicentre observational study in 11 paediatric emergency departments with different characteristics and geographical location, we collected data on 3061 children aged 6 months to 15 years with AD and no complications.
Bismuth produces different types of ordered superstructures on the InAs(100) surface, depending on the growth procedure and coverage. The (2 × 1) phase forms at completion of one Bi monolayer and consists of a uniformly oriented array of parallel lines of Bi dimers. Scanning tunneling and core level spectroscopies demonstrate its metallic character, in contrast with the semiconducting properties expected on the basis of the electron counting principle.

By using angle- and spin-resolved photoemission spectroscopy and ab initio calculations, we show that the intercalation of Eu in the graphene/Ni(111) interface gives rise to a gapped freestanding dispersion of the ππ^{*} Dirac cones at the K[over ¯] point with an additional lifting of the spin degeneracy due to the mixing of graphene and Eu states. The interaction with the magnetic substrate results in a large spin-dependent gap in the Dirac cones with a topological nature characterized by a large Berry curvature and a spin-polarized Van Hove singularity, whose closeness to the Fermi level gives rise to a polaronic band.
