in this paper, the photochemical degradation of azure-b by cu2+/s2o82− process has beenpresented. cu2+ as photocatalyst and s2o82− ion as photooxidant used in this process. atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.the influence of various parameters on the performance of the treatment process has beenconsidered, such as ph, concentration o...

We have measured the concentration dependence of the transmission conduction electron spin resonance linewidth of copper doped with Li, Zn, Ga, Ge, As, Ni, and Ti. In each case, we find a linear concentration dependence which allows us to determine a spin-flip cross-section, 03C3sf, for each impurity. These crosssections, together with those deduced from linewidth data previously published for ...

This paper proposed a fractional model for the flow rate and characteristic of the impurity of order α, β(0<α, β≤1) respectively, which describes one dimensional dynamical flows of electrically conducting fluid. In this model fractional derivatives are described in the Caputo sense. The beauty of the paper is residual analysis which shows that our approximate solution converges very rapidly to ...

ICRF provides Alcator C-Mod with up to 3.5 MW of power at 80 MHz using two double-strap antennas. By varying the magnetic field and the mix of ion species, a variety of heating regimes have been studied. To investigate electron heating regimes, mixtures of He3 and H were used in plasmas at 6.5T. Efficient ( < 80%) direct electron heating has been observed in this scenario and is attributed to m...

During the leaching process of ionic rare earth ore (ICREO), ion-exchangeable phase calcium (IEP-Ca) and aluminum (IEP-Al) are leached along with earth, which causes many problems in enrichment process, such as increasing precipitant agent consumption loss, etc. The agitation kinetics column mass transfer IEP-Ca IEP-Al were studied to understand behavior impurity ICREO, provides guides for adju...

The paper presents a coupled isothermal model at the initial stage of a solid surface treatment with particle beams. Mechanical stresses arising due to the interaction of particles with the surface affect the redistribution of the implanted impurity. Vacancies in the metal surface and their generation under stress are also taken into account. The kinetic law is formulated on the basis of thermo...

In subsonic tokamak pedestals the radial scale of plasma profiles can be comparable to the ion poloidal Larmor radius, thereby making the radial electrostatic field so strong that the E × B drift has to be retained in the ion kinetic equation in the same order as the parallel streaming. The modifications of neoclassical plateau regime transport – such as the ion heat flux, and the poloidal ion ...
