Kinetics of Adsorption The kinetics of adsorption of dye by CAC, RAC, CSC and SDC have been studied by testing the applicability of the first order kinetic equations proposed by Natarajan – Khalaf [38], Lagergren – as cited by Pandey et al [39] and Bhattacharya and Venkobachar[40].

The high Al content is used to stabilize ferrite and obtain a consistent mixture of ferrite matrix, bainite and retained austenite.

One of the possible reasons is that the nitrogen of shielding gas diffuses into melt at cooling and precipitates together with Al, and it is unable to diffuse so quickly into the partially unmelt HAZ.

Chen et al. describes the laser-ablation plume into three regimes, 1) elastic scattering regime that is described by drag model close to the target, 2) a reactive collision regime that is described by blast wave model, and 3) a sound wave regime (free diffusion model) [23].

Soares et al. (2014) have simulated the mobilization of residual oil ganglia by the magnetic stresses generated in a ferrofluid.
Ryoo et al. (2012) use ferrofluid made of iron oxide nanorods that is sufficient to produce measurable displacement of the interface between fluid and a ferrofluid when exposed to an oscillatory magnetic field [11].
After double-annealing process at 1000°C and 1200°C for 2 hours, almost pure YIG nanoparticles formed as similar to the finding in Ristic et al. (2003) although a different chemical route was used in this work [17].
