Schematically deciphering the electrochemical mechanism of electrochromic NiO<sub>x</sub> thin film based on Li<sup>+</sup>-ion electrolytes.
We report the first nanoindentation studies of well-ordered nanocrystal supercrystals composed 7 nm lead sulfide nanocrystals stabilized with oleic acid ligands as a model system. Their modulus and hardness were found to be similar hard polymers at 1.7 GPa 70 MPa, respectively, fracture toughness was 40 KPa/m1/2, revealing brittle nature these materials. The mechanical properties are dominated by organic capping agents surrounding inorganic cores. close-packed structure distributes stress...
An overview of the recent progress on plasma-assisted CO2 conversion in microwave discharges is given. Special attention devoted to results obtained using plasma catalysis, which are compared plasma-only decomposition cases. The effects operating conditions, catalyst preparation methods, nature activation gas, gas mixture, as well NiO content TiO2 surface and its energy efficiency discussed. A significant improvement with a NiO/TiO2 activated Ar plasma, when about 10 wt.%. characterization...
This work presents a simple, fast (20 min treatment), inexpensive, and highly efficient method for synthesizing nitrogen-doped titanium dioxide (N-TiO2) as an enhanced visible light photocatalyst. In this study, N-TiO2 coatings were fabricated by atmospheric pressure dielectric barrier discharge (DBD) at room temperature. The composition the chemical bonds of TiO2 characterized X-ray photoelectron spectroscopy (XPS) time-of-flight secondary ion mass (ToF-SIMS). results indicate that nitrogen...
An Ar plasma sustained by a surfaguide wave launcher is investigated at intermediate pressure (200–2667 Pa). Two 2D self‐consistent models (quasi‐neutral and bulk‐sheath) are developed benchmarked. The complete set of electromagnetic fluid equations the boundary conditions presented. transformation from local reference frame, that is, moving with or when gas flow zero, to laboratory accounting for flow, discussed. range extended down 80 Pa experimental measurements. electron temperature...
The oxidation kinetics of AlTiTaN hard coatings deposited at 265 °C by DC magnetron sputtering were investigated between 700 and 950 for various durations. By combining dynamic secondary ion mass spectrometry (D-SIMS), X-ray diffraction (XRD), transmission electron microscopy (TEM) investigations the different oxidized coatings, we able to highlight mechanisms involved. TEM cross-section observations combined with XRD analysis show that a single amorphous oxide layer comprising Ti, Al, Ta...
Dual source metal plasma immersion ion implantation and deposition was used to deposit TixCy films over a wide range of Ti:C composition. This technique is well adapted for this purpose allows one tailor the microstructure properties films. We investigated variation composition, bonding states, structure as functions conditions. Excess carbon contamination oxygen are incorporated in TiC lattice interstitially substitutionally, respectively. The wear mechanism stoichiometric film compared...
AlTiTaN coatings have been demonstrated to high thermal stability at temperatures up 900 °C. It has speculated that the oxidation resistance promotes an improved wear resistance, specifically for dry machining applications. This work reports on influence of temperature °C mechanisms hard coatings. DC magnetron-sputtered were obtained from Al46Ti42Ta12 target, keeping substrate bias −100 V and 265 The exhibited a single-phase face-centered cubic structure. sliding tests revealed predominant...
