As a starting point, a new 3D porous framework with the {CoL·0.5DMF·H
O}
chemical formula (where L = 3-amino-4-hydroxybenzoate) is described. Its performance as a single molecule magnet was explored. ...The study of magnetic properties reveals that Co-MOF shows no frequency-fdependant alternating current (
) signals under zero direct current (
) magnetic field, whereas single-molecule magnet behaviour is achieved when Co
ions are diluted in a Zn
based matrix. Interestingly, this strategy renders a bifunctional Co
Zn
L
material that is also characterized by a strong photoluminescent emitting capacity.
Helix sense selection: Tuning the conformational equilibrium of the pendants of poly(phenylacetylene)s allows selection of the helicity of the polymer in a reversible way. Complexation with ...appropriate metal cations (e.g. Ba2+) or changing the polarity of the solvent permits the reversible selection of the desired helix sense. A full picture of the mechanism explaining this phenomenon is presented.
Peripheral venous catheter-associated bloodstream infections (PVC-BSIs) lead to prolonged hospitalization, morbidity and increased costs. The impact of infection-prevention measures on the rate of ...PVC-BSIs in a university hospital in Spain was assessed. An active surveillance programme was initiated in 2015, which revealed a high PVC-BSI incidence ratio (0.48/1000 patient-days). A bundle aimed at nurses, medical staff and patients was implemented, and a Catheter Infection Team (CIT) was set up. The intervention achieved a decrease in PVC-BSI rate: 0.34 in 2016, 0.29 in 2017, and 0.17 in 2018. The decline was greatest for Gram-negative PVC-BSIs (67.6% in 2015, 35.3% in 2018).
In this work a family of multidimensional (2‐(1H‐tetrazol‐5‐yl)ethyl) amino acid coordination compounds have been synthesized and thoroughly characterized. For this purpose, glycine, valine, ...phenylalanine and tyrosine have been selected as starting amino acids and Mn2+, Zn2+ and Cd2+ as metallic nodes. From one side, for Mn2+ based dimer magnetic resonance imaging studies have been conducted, prompted by the number and disposition of the coordinated water molecules and taking into consideration the promising future of manganese‐based coordination compounds as bio‐compatible substitutes to conventional Gd based contrast agents. From another side, d10 block metal‐based complexes allowed exploring photoluminescence properties derived by in situ synthesized ligands. Finally, amino acid preserved structural chirality allowed us to examine chiroptical properties, particularly focusing on circularly polarized luminescence.
A family of multidimensional coordination compounds have been synthesized based on glycine, valine, phenylalanine and tyrosine. Magnetic resonance imaging studies and chiroptical properties have been explored.
