Three kinds of MnO₂/Ni foam composite electrode with hierarchical meso-macroporous structures were prepared using potentiodynamic (PD), potentiostatic (PS), and a combination PS PD(PS + PD) modes electrodeposition. The electrodeposition mode markedly influenced the surface morphological, textural, supercapacitive properties electrodes. performance obtained via PD(MnO₂/Ni)) was found to be superior those electrodes PD PS, respectively. Moreover, an asymmetric supercapacitor device, activated...

The titanium dioxide (TiO 2 ) photocatalysts were synthesized by a solvothermal process in highly alkaline 70 : 30 water ketone solutions with TiO ‐P25 precursor and calcined at different temperatures. solvents, such as acetone methyl ethyl (MEK), had low boiling points (<100°C). as‐prepared samples characterized XRD, TEM, FTIR, UV‐vis Raman spectroscopy. effects of the solvents on nanostructure, morphology, photocatalytic performance products investigated. Nanotubes formed water‐MEK,...
TiCl4 or titanium isopropoxide reacted with citric acid to form a titanyl citrate precipitate. Barium strontium solutions were then added the reaction gels. These gels dried and calcined (Ba,Sr)TiO3 powders. The powders characterized by DSC/TGA, IR, SEM XRD analyses. results showed that, at 500 °C, decomposed Ba,Sr carbonate TiO2, followed formation of (Ba,Sr)TiO3. onset perovskite occurred 600 was nearly complete 1000 °C. Traces SrCO3 still present. cation ratios titanate powder prepared in...
The effect of activation temperature on the structural properties and electrochemical performance KOH-activated carbon xerogel was investigated in range 700 to 1000°C. At a high (1000°C), chemical regenerated more crystalline network structure activated xerogels, which observed by Raman, XRD, TEM images. Additionally, SEM images, BET, BJH, <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:mi>t</mml:mi></mml:mrow></mml:math>-plot were used study xerogels. sample...
Titanate nanotubes were synthesized by a hydrothermal method using commercial TiO 2 powder and then used as photocatalyst. The titanate varying the temperature from 110°C to 180°C. morphological changes phase transformation of analyzed X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM). particles’ scattering behavior was investigated Raman studies, surface area determined Brunauer, Emmett, Teller (BET) analysis. Comparative studies show that increases with...
We have synthesized the characteristics of seismogenic zone in east Los Angeles basin by analyzing earthquake data recorded during past 30 years .The seismicity is distributed along Whittier fault, with majority earthquakes located adjacent to south side, depth range from 0 9 km, b value 1:1 0:05 and mostly normal strike-slip faulting.Within 9-12 scattered uniformly across region, 1:0 0:05, all three faulting styles are present.At deepest depths (12-18 km), sparse primarily limited a few...
The faujasite framework structure and the morphological properties of Co 2+ -exchanged NaX zeolite were maintained when samples treated at a temperature ≤600℃, but distorted higher temperature. cobalt (II) exchange thermal treatment processes significantly improved H 2 S adsorption capacity highest values 4.24 mg g −1 for 0.10-CoX-600 4.42 0.15-CoX-600. Moreover, first-order kinetic showed relatively good fit applied to experimental data process.
