Conversion and alloying type negative electrodes attracted huge attention in the present research on lithium/sodium-ion batteries (LIBs/SIBs) due to high capacity delivered. Among these, SnO2 is investigated intensively LIBs cyclability, low reaction potential, cost-effectiveness, environmental friendliness. Most of LIB are explored SIBs too expected similar electrochemical performance. Though several electrode materials successfully worked SIBs, bare shows very poor performance SIB. The...
The mobility, bioavailability and toxicity of mercury in the environment strongly depend on chemical species which it is present soil, sediments, water or air. In mining districts, differences mobility mainly arise from different type mineralization ore processing. this work, synchrotron-based X-ray absorption near-edge spectroscopy (XANES) has been taken advantage to study speciation geological samples three largest European districts: Almadén (Spain), Idria (Slovenia) Asturias (Spain)....
Problem statement: Metal mining; together with mineral smelting and processing, have contaminated the environment surrounding mine areas throughout world exceeding natural background concentration. Approach: These processes introduce metal contaminants into through gaseous particulate emissions, waste liquids solid wastes. The principal objective of this study was to investigate soil water contamination in vicinity kettara abandoned located South Morocco. Results: High total concentrations...
To evaluate the efficacy, safety, pain perception and health-related quality of life (QoL) percutaneous ethanol injection treatment (PEIT) as an alternative to thyroid surgery in symptomatic cysts. Thirty consecutive patients (46 ± 10 years; 82 % women) with benign cysts relapsed after drainage were included. In all cases, cytology prior treatment, maximum cyst diameter volume determined. PEIT was conducted using established procedure, fluid removed perceived by patient assessed. each...
We have investigated the local structure of differently charged NaxCoO2 cathode material as a function temperature by Co K-edge X-ray absorption fine (EXAFS) measurements. found that charge/discharge process has direct effect on bond characteristics in Na-ion batteries. The results reveal Co–O bonds get softer, while Co–Co hardly show any change during discharge (sodiation). present study underlines key role atomic displacements diffusion and reversibility ions cathodes for batteries points...
The present study represents a first insight into the Draa Lasfar mine (Marrakech) to assess possible diffusion of heavy metals and predict risk their mobility in surroundings area.The edaphologic parameters pH, electrical conductivity (EC), loss on ignition (LOI) CaCO 3 were measured according standard methods, whilst concentration was determined by FP-XRF.Concentration enrichment ratios (CER) calculated order estimate anthropogenic contribution target pollutants determining As, Cu, Pb Zn...
We demonstrate the use of commercially available fused silica capillary and fittings to construct a cell for operando X-ray absorption spectroscopy (XAS) study heterogeneously catalyzed reactions under high pressure (up 200 bars) temperature 280 °C) conditions. As first demonstration, was used CO2 hydrogenation reaction examine state copper in conventional Cu/ZnO/Al2O3 methanol synthesis catalyst. The active component catalyst shown remain metallic supercritical conditions, at bars up 260...
Nanomaterials of ZnO-PLLA nanofibers have been used for the adsorption Cr(VI) as a prime step purification water. The fabrication and application flexible nanofiber nanocomposite functional materials in this well-developed architecture achieved by growing ZnO nanorod arrays chemical bath deposition on synthesized electrospun poly-L-lactide nanofibers. material has tested removal regeneration Cr(IV) aqueous solution under “continuous flow mode” studying effects pH, contact time, desorption...
Study of the effect Ag-NPs stripes in Nafion: evaluation chemical, electrochemical and mechanical properties.
We have investigated the nanostructuring effects on local structure of V2O5 cathode material by means temperature dependent V K-edge X-ray absorption fine measurements. found that largely affects V-O and V-V bond characteristics with a general softening bonds. The obtained strengths correlate specific capacity shown different systems, higher corresponding to softer atomic pairs. present study suggests key role displacements in diffusion storage ions cathodes for batteries, providing...
Abstract The feasibility of three commercial extractants (DEHPA, Cyanex 272, and Ionquest 290) has been assessed for the recovery Zn from an acidic mine effluent. Less than 5 min are required to reach equilibrium studied extractants. Regarding selectivity, DEHPA extracted efficiently Zn, Ca, Mn, Al, although Al remained in solvent extract after stripping, hindering reuse. Neither 290 nor 272 Cu, or Ca significantly. is 5–10% higher 272. In addition, 20%(v/v) produces recoveries 40%(v/v)...
Nominal ${[\mathrm{Fe}(t)/\mathrm{Ir}({t}^{\ensuremath{'}})]}_{n}$ (M/M type), ${[\mathrm{FeOx}(t)/\mathrm{IrOx}({t}^{\ensuremath{'}})]}_{n}$ (O/O), and ${[\mathrm{Fe}(t)/\mathrm{IrOx}({t}^{\ensuremath{'}})]}_{n}$ (M/O) multilayers have been prepared by magnetron sputtering at room temperature. Composition, structure, magnetic behavior analyzed. In the M/M samples, Fe Ir phases are identified as bcc fcc, respectively. The magnetism evolves from bulklike iron to granular thickness of layers...
The study aims at a first approach to university students in relation the group/collective anchors they had, during COVID 19 pandemic, and made viable continuity of their career, instead abandoning it. Two main objectives current research are: To know resilient strategies that possible educational Social Work Political Science pandemic. describe social favored such continuity. methodology implemented is based on an exploratory descriptive study, whose triangulation qualitative quantitative...
To exploit LIBs to their maximum applications, innovative electrode materials should be developed and existing improved. As negative are needed in excess comparison with positive (in terms of specific capacity) a lithium-ion battery, it is important reduce amounts so as the cell size production cost [1] . Moreover, material classes delivering high capacity offering fast Li diffusion kinetics developed. Parallel this, research alternative low energy storage systems became more intensive. Due...
