Main objective of this paper is to investigate comparative analysis of Copper-water and Copper Oxide-Water nanofluids flow due to a stretchable plate. Magnetic field is applied in transverse direction. Energy equation contains impacts of viscous dissipation and Joule heating. Appropriate dimensionless ...
Using the Langmuir constant, KL, obtained from single-site Langmuir model16, and Blanchard’s32 original proposed equation (see the Supporting Information), we determined that the Gibbs free energy of copper ion adsorption by ZIOS is −27.23 kJ mol−1, indicating that uptake is also ...
A good correlation was found between the stripping signals and predictions based on the Levich equation for deposition at a rotating disk electrode and the De Vries and Van Dalen equation for stripping from a thin film electrode. The effect of sample acidity was examined and it was concluded ...
In the end, the regression equation about the time-averaged Nusselt number is obtained as parameters of the solid volume fraction and the oscillating area.doi:10.1016/j.csite.2015.07.001Han, XilianSchool of Civil Engineering, Lanzhou University of Technology, Lanzhou 730050, PR China;College of ...
According to the Arrhenius equation, the lifespan of an electronic device is cut in half when its temperature increases by 10 °C11,12. Therefore, it is necessary to develop heat sinks that can immediately release the heat generated by electronic devices. One of the properties required for ...
Based on the chemical equation (N2 + CO2 + 6H + + 6e– → CON2H4 + H2O), six electrons are needed to produce one urea molecule [5]. Thus, the FE can be calculated using Eq. 1: FE=QureaQ=6×F×V×CureaMurea×Q (1) The rate of formation of ...

The calibration graph is linear in the range 1-90 μmol dm-3 of copper, correlation coefficient is 0.993, the regression equation is I = (0.0455±0.0015)c + (0.4611±0.0671), I is relative signal decrease in μA and c is concentration in μmol dm-3. Relative standard deviation for ...
The monolayer adsorption capacity determined from the Langmuir adsorption equation has been found as 111.1 mg/g. Kineticmeasurements suggest the involvement of pseudo-second-order kinetics in adsorptions and is controlled by a particle diffusion process. Adsorption of Cu(II) on adsorbents was found ...
Real-solution stability diagrams for copper-ammonia-chloride-water system Abstract A comprehensive thermodynamic model, which combined the Helgeson-Kirkham-Flowers (HKF) equation of state for standard-state thermodynamic properties of all species with realistic activity coefficient model developed by BROMLEY,...
