Vanadium pentoxide (V2O5) attracts considerable attention in electrochromism due to its multicolor aspects and high ion storage capacity for the counter electrode. In this work, pure Fe-doped V2O5 films are deposited by radiofrequency magnetron co-sputtering. The influence of Fe doping on structural electrochemical properties V2O5-based thin is investigated. Thin containing up 7.8 atom % obtained without phase impurities. Although detrimental electrochromic properties, a proper amount about...
Polyanionic positive electrode materials such as Na3V2(PO4)2F3 are renowned for their exceptional rate performance and long-term stability during cycling. However, they present low tap densities that penalize the volumetric energy density when it comes to practical applications. In this study, we successfully increased of carbon-coated by 40% through mechanical grinding dense particles previously obtained via solid-state reaction, resulting in an impressively high 1.4 g/cm3. Comprehensive...
Deep eutectic solvents (DES) are well-known as cost-effective and environmentally friendly "designer solvents" for controlling the size morphology of nanomaterials. In this study, we leverage DES not only a solvent topochemical synthesis Na3V2(PO4)2F3–yOy (0 ≤ y 2) but also precursor uniform thin carbon coating. After solvothermal in green deep composed mixture choline chloride, citric acid, water (3:1:3 molar ratio), XRD refinements FTIR, XPS, TEM analyses confirmed obtention pure phase...
Since its discovery, electrochromism, known as the modulation of optical properties under an applied voltage, has attracted strong interest from scientific community and proved to be significant utility in various applications. Although vanadium dioxide (VO2) been a candidate for extensive research thermochromic properties, intrinsic electrochromism scarcely reported so far. In this study, multi-electrochromism is described VO2 thick films. Indeed, opaque film, doctor bladed homemade...
Abstract Graphene in water is electrically charged most conditions. The level of charge can be large enough to stabilize single (or few) layer graphene colloidal dispersions water, without the need using any other additive. In this work, potentiometric titration, isothermal titration calorimetry, electrokinetic measurements, Density Functional Theory calculations, Raman Spectroscopy, and direct force measurements Atomic Force Microscopy investigate explore its origin are combined. body data...
Cobalt-doped zinc oxide nanoparticles (NPs) were synthesized using a modified sol-gel method. Thereafter, the obtained powder was deposited on Suprasil glass substrate by employing pulsed laser deposition (PLD) technique. X-ray diffraction analysis with Rietveld refinement confirmed hexagonal wurtzite ZnO phase belonging to P63 mc space group for both samples in NP and thin film forms. In particular, exhibited an intensive (002) XRD peak, indicating that it had preferred c-axis orientation...
Abstract The memory effect property, described as a reversible color persistence while the potential is withdrawn, of particular importance to reaching zero‐energy consumption electrochromic devices. Nevertheless, often observed in organic materials, it poorly studied oxides. In this study, tungsten oxide thin films are elaborated at different working pressures by radiofrequency magnetron sputtering. influence deposition pressure on electrochemical properties WO 3 well their investigated....

This article describes an approach to making highly stable copper nanowire networks on any type of substrates. These nanostructured materials are sought after for, among other applications, the development next-generation flexible electronics. Their high susceptibility oxidation in air currently limits their use real world. Here, we develop a multistep chemical method fabricate transparent electrodes (TEs) using Cu-based bimetallic NW various substrates at room temperature. First,...
A little is enough: ultrathin fluorous layers improve perovskite surface properties.
Among candidates at the positive electrode of next generation Li-ion technology and even beyond post as all-solid-state batteries, spinel LiNi0.5Mn1.5O4 (LNMO) is one favorites. Nevertheless, before its integration into commercial systems, challenges still remain to be tackled, especially stabilization interfaces with electrolyte (liquid or solid) high voltage. In this work, a simple, fast, cheap process used prepare homogeneous coating Al2O3 type modify surface LNMO: supercritical fluid...
The constant increase in current density electrical wires leads to increasingly significant heat losses due Joule effect. Therefore, reducing the resistivity of copper becomes necessary. To achieve this goal, development a composite material incorporating more conductive reinforcement, graphene, is promising way. design copper/graphene using powder metallurgy-based method presented. This synthesis allows for interface control through growth CuO(Cu) nanoparticles tightly bonded reinforcement....

In the general context of environmental air remediation, copper-oxide-based self-standing porous catalysts (MUB-103(x)) and their reduced homologues (Red MUB-103(x)) have been synthesized studied for thermoconversion CO to CO2. Catalytic experiments under dry conditions reveal that nonreduced catalysts, increasing Cu content diminishes light-off temperature T50 (corresponding 50% conversion). The catalytic performances exhibited by CuO phase dispersed in silica pores MUB-103(x) samples are...
