Study Of Spilled Oil Behavior On The Topsoil Induced By Thermal Diffusion, Nirmala P. Ratchagar, S. V. Hemalatha
Applications and Applied Mathematics: An International Journal (AAM)
The fate and transport of oil spilled in soil has long been a focus for experimental and theoretical research in subsurface hydrology. Oil transport in the soil is affected by a large number of physical, chemical and microbial processes; and the properties of the media. This study is a two layer problem containing horizontal oil layer overlying the subsurface topsoil region saturated with oil and water (native fluid). To explain the method by which the convective flow in the oil region affect the transportation of oil, modeling is carried out in two regions (oil and topsoil). The two dimensional, transient …
Study Of Fe3o4 Nanoparticles Degradation Process, A. Kozlovskiy, D. Tuleubayeva, K. K. Kadyrzhanov
Study Of Fe3o4 Nanoparticles Degradation Process, A. Kozlovskiy, D. Tuleubayeva, K. K. Kadyrzhanov
Eurasian Journal of Physics and Functional Materials
The purpose of this work was to study the oxidation and destruction processes of Fe3O4 nanoparticles. As a result, dynamic changes in structure and phase composition of Fe3O4 nanoparticles in various pH media was set. The acidity and time dependence of degradation degree on the pH medium was established. It was associated with the appearance of amorphous regions which is due to the presence of hydroxide compounds. By understanding of the nanoparticles degradation rate and degree it becomes possible to clarify the residence time for the nanoparticles, which in turn makes them potential materials …
