Multifunctional Dy Complexes with Triphenylmethanolates: Structural Diversity, Luminescence, and Magnetic Relaxation.

The coordination environment of magneto-luminescent Dy-based Single-Molecule Magnets (SMM) is a crucial factor influencing both magnetic and luminescent properties. In this work, we explore how triphenylmethanolate (PhCO), in combination with other ligands, can modulate the structure and, therefore, the magnetic properties of Dy-based SMM. Using triphenylmethanolate in combination with THF and pyridine (Py) as co-ligands, we synthesized a series of mononuclear -[Dy(OCPh)(THF)][BPh]·(2,6-MeCHN) (), -Dy(OCPh)(THF) (), -Dy(OCPh)(py) () and dinuclear [(PhCO)Dy(THF){(μ-Cl)Li(THF)}μ-Cl] () complexes where the Dy ion presents five- or six-coordinate geometries.

Influence of the Structure of Hydrothermal-Synthesized TiO Nanowires Formed by Annealing on the Photocatalytic Reduction of CO in HO Vapor.

The present study investigates the photocatalytic properties of hydrothermally synthesized TiO nanowires (NWs) for CO reduction in HO vapor. It has been demonstrated that TiO NWs, thermally treated at 500-700 °C, demonstrate an almost tenfold higher yield of products compared to the known commercial powder TiO P25. It has been found that the best material is a combination of anatase, TiO-B and rutile.

Giant ultrafast dichroism and birefringence with active nonlocal metasurfaces.

Switching of light polarization on the sub-picosecond timescale is a crucial functionality for applications in a variety of contexts, including telecommunications, biology and chemistry. The ability to control polarization at ultrafast speed would pave the way for the development of unprecedented free-space optical links and of novel techniques for probing dynamical processes in complex systems, as chiral molecules. Such high switching speeds can only be reached with an all-optical paradigm, i.

Impact of Hydroxyapatite on Gelatin/Oxidized Alginate 3D-Printed Cryogel Scaffolds.

Fabrication of scaffolds via 3D printing is a promising approach for tissue engineering. In this study, we combined 3D printing with cryogenic crosslinking to create biocompatible gelatin/oxidized alginate (Gel/OxAlg) scaffolds with large pore sizes, beneficial for bone tissue regeneration. To enhance the osteogenic effects and mechanical properties of these scaffolds, we evaluated the impact of hydroxyapatite (HAp) on the rheological characteristics of the 2.
