Hybridization effects on the magnetic ground state of ruthenium in double perovskite LaZnRuTiO.

An exotic quantum mechanical ground state, i.e. the nonmagnetic= 0 state, has been predicted for higher transition metal tsystems, due to the influence of strong spin-orbit coupling (SOC) or in other words, due to unquenched orbital moment contribution.

Anticancer potential of copper(i) complexes based on isopropyl ester derivatives of bis(pyrazol-1-yl)acetate ligands.

In this paper, the isopropyl ester derivatives L and L of bis(pyrazol-1-yl)acetic acid and bis(3,5-dimethyl-pyrazol-1-yl)acetic acid were used as chelators for the preparation of new Cu(i) phosphane complexes 1-4. They were synthesized by the reaction of [Cu(CHCN)]PF and triphenylphosphine or 1,3,5-triaza-7-phosphaadamantane with L and L ligands, in acetonitrile or acetonitrile/methanol solution. The authenticity of the compounds was confirmed by CHN analysis, H-, C- and P-NMR, FT-IR spectroscopy, and electrospray ionization mass spectrometry (ESI-MS).

Anomalous lattice contraction and emerging topological phases in Bi-substituted SmIrO.

We demonstrate that substituting Bi for Sm in the pyrochlore Sm$_2$Ir$_2$O$_7$ induces an anomalous lattice contraction, with $\Delta a \sim -0.012$~\AA~observed at 10\% Bi substitution, where 'a' denotes the lattice constant. Beyond 10\% Bi substitution, the lattice expands according to Vegard's law.

Oxygen-Mediated (0D) CsPbX Formation during Open-Air Thermal Processing Improves Inorganic Perovskite Solar Cell Performance.

The desire to commercialize perovskite solar cells continues to mount, motivating the development of scalable production. Evaluations of the impact of open-air processing have revealed a variety of physical changes in the fabricated devices─with few changes having the capacity to be functionalized. Here, we highlight the beneficial role of ambient oxygen during the open-air thermal processing of metastable γ-CsPbI-based perovskite thin films and devices.
