Redox-switching of ternary Ni(ii) and Cu(ii) complexes synthesis, experimental and theoretical studies along with second-order nonlinear optical properties

Four new ternary Ni(ii) and Cu(ii) complexes of ONO tridentate Schiff base and pyridylmethylenepyran (PyMP) ligands [(R-ONO)M(PyMP)] (R = anisyl = An M = Ni 1, Cu 2; R = ferrocenyl = Fc M = Ni 3, Cu 4) have been synthesized under facile reaction…

Supraconductivité

An observable prerequisite for the existence of persistent currents

A classical model is presented for persistent currents in superconductors. Their existence is argued to be warranted because their decay would violate the second law of thermodynamics. This conclusion is achieved by analyzing comparatively Ohm's law…

Nitrogen impurities and fluorescent NVcenters in detonation nanodiamonds: identification and distinct features

We show that nitrogen is the main impurity contained in detonation nano-diamonds (DNDs), at a concentration of ~16000 ppm. The content of nitrogen-vacancy (NV-) centers in these DNDs is ~2.7 ppm, which is the largest of all known types of nano…

Burning TADF Solids Reveals their Excitons’ Mobility tototo

Thermally Activated Delayed Fluorescence (TADF) compounds contribute to the light emission of an optoelectronic device by harvesting both their singlet and triplet states. But quenching limits such benefits at high current densities. In the case of…

Out-of-plane modes in three-dimensional Fabry-Perot microlasers

Microlasers are involved in a broad range of devices for numerous research applications. However, the mode structures of three-dimensional microlasers without rotational symmetry are largely unexplored. Previous studies of such cavities revealed…
