    “…At 1 M concentrations in the subphase, the identity of the anion is shown to have a remarkable influence on the charging behavior and degree of deprotonation of the monolayer, with ions ordering in the sequence I(–) > SCN(–) > Cl(–) ≈ Br(–). The same trend is observed at both pH 6 and pH 9 when the monolayer is intrinsically more charged. …”

    “…The experimental results are complemented by density functional theory calculations showing that C(60)Br(24) in contact with SWCNTs induces localized hole doping in the nanotubes, which is increased further when H(2)S adsorbs on C(60)Br(24) but decreases in the regions, where direct adsorption of H(2)S on the nanotubes takes place due to electron doping from the analyte. …”

    “…Here, we demonstrate that Cd(2+) doping simultaneously improves both the linear (higher photoluminescence quantum yield, larger exciton binding energy, reduced trap states density, and faster radiative recombination) and nonlinear (higher two- and three-photon absorption cross-sections) optical properties of CsPbBr(3) NCs. Cd(2+) doping results in a two-photon absorption cross-section, reaching 2.6 × 10(6) Goeppert-Mayer (GM), which is among the highest reported for CsPbBr(3) NCs.…”

    “…[Image: see text] The reaction of the uranium(IV) halides UCl(4), UBr(4), or UI(4) with ethyl acetate (EtOAc) leads to the formation of the complexes [UX(3)(EtOAc)(4)][UX(5)(EtOAc)] (X = Cl, Br) or [UI(4)(EtOAc)(3)]. Thus, both UCl(4) and UBr(4) show self-ionization in ethyl acetate to a distorted pentagonal bipyramidal [UX(3)(EtOAc)(4)](+) cation and a distorted octahedral [UX(5)(EtOAc)](−) anion. …”
