Non-aqueous Li- and Na-O2 batteries: Study and analysis of electrochemical processes
(2016-12-14)
Las baterías M-oxígeno, siendo M un metal alcalino, son conocidas por su extraordinaria densidad energética teórica. En esta tesis se estudian en detalle las reacciones que tienen lugar en las baterías de litio y de sodio ...
High voltage cathodes for Na-ion batteries: Na3V2O2x(PO4)2F3-2x system
(2014-07-14)
Batteries are one of the most promising energy storage devices. Among them, sodium-ion batteries are presented as the best alternative to lithium-ion batteries especially in the field of stationary energy storage due to ...
Ionothermal Synthesis of Cadmium Coordination Polymers: Ionic Liquid Effects on the Synthesis, Structural, and Thermal Characterization
(MDPI, 2019-11-09)
Ionothermal synthesis is a little used method for the preparation of coordination polymers. By this method, two cadmium compounds were synthesized, 1, with formula Cd-3(ox)F-2(Ina)(2) (Ina = isonicotinate) and 2, Cd(NO3)(2)(4,4 ...
Slow Magnetic Relaxation and Luminescent Properties of Mononuclear Lanthanide-Substituted Keggin-Type Polyoxotungstates with Compartmental Organic Ligands
(American Chemical Society, 2022-02-07)
The reaction of mid to late lanthanide ions with the N,N'-dimethyl-N,N'-bis(2-hydroxy-3-formyl-5-bromobenzyl)ethylene-diamine organic ligand and monolacunary Keggin type [alpha-SiW11O39]8- anion affords a series of ...
Synthesis, Structural Features and Physical Properties of a Family of Triply Bridged Dinuclear 3d-4f Complexes
(MDPI, 2021-02-05)
New dinuclear MII-LnIII complexes of general formulas [Cu(µ-L)(µ-OAc)Ln(NO3)2]·CH3CN·H2O (LnIII = Gd (1), Tb (2), Dy (3) and Er (4)), [Ni(CH3CN)(µ-L)(µ-OAc)Ln(NO3)2]·CH3CN (LnIII = Nd (5), Gd (6), Tb (7), Dy (8), Er (9) ...
An in solution adsorption characterization technique based on the response to an external magnetic field of porous paramagnetic materials: application on supramolecular metal–adenine frameworks containing heterometallic heptameric clusters
(Royal Society of Chemistry, 2023-01-18)
Herein we explore the opportunities arising from combining magnetic properties and porosity in metal–organic materials. In this sense, we have prepared an adenine based homometallic wheel-shaped heptameric [Cu7(μ-adenina ...
Antitumor magnetic hyperthermia induced by RGD-functionalized Fe3O4 nanoparticles, in an experimental model of colorectal liver metastases
(Beilstein-Institut, 2016-10-28)
This work reports important advances in the study of magnetic nanoparticles (MNPs) related to their application in different research fields such as magnetic hyperthermia. Nanotherapy based on targeted nanoparticles could ...
Natural and recyclable alginate hydrogels as extracting media for recovering valuable metals of spent lithium-ion batteries from a deep eutectic solvent
(Elsevier, 2023-09-07)
With the aim of achieving carbon neutrality, new policies to promote electric vehicle (EV) deployment have been announced in various countries. As EV sales gain market-share, the demand for batteries is growing very rapidly, ...
Adenine nucleobase directed supramolecular architectures based on ferrimagnetic heptanuclear copper(II) entities and benzenecarboxylate anions
(Elsevier, 2019-10-05)
Two planar organic anions, benzoate and benzene-1,4-dicarboxylate (terephthalate), have been selected as potential π-stacking intercalators among ferrimagnetic [Cu7(μ-adeninato)6(μ3-OH)6(μ-H2O)6]2+ heptameric discrete ...
Highly packed graphene–CNT films as electrodes for aqueous supercapacitors with high volumetric performance
