Surface Complexation and Its Impact on Geochemical Kinetics*
The weathering of rocks, the formation of soils, the alteration and dissolution of sediments are a consequence of surface reac-. tions. Furthermore, many redox processes such as the oxidation of V02+, Mn2+ and Fe2+, the ncn-biotic degradation of organic substances and photosensitized processes are catalyzed by surfaces. The electric double layer theory, despite its efficiency in quantifying cer...
متن کاملMolecular Dynamics Studies on Fundamental Molecular Surface Processes
In this contribution, we give examples of results recently obtained in fundamental molecular dynamics studies and DFT electronic structure calculations performed on prototype surface processes due to the interaction of atomic and molecular oxygen, nitrogen, hydrogen, C on substrates of different nature. The discussed systems are known to be among the most important heterogeneous systems relevan...
متن کامل2D Analytical Modeling of Magnetic Vector Potential in Surface Mounted and Surface Inset Permanent Magnet Machines
A 2D analytical method for magnetic vector potential calculation in inner rotor surface mounted and surface inset permanent magnet machines considering slotting effects, magnetization orientation and winding layout has been proposed in this paper. The analytical method is based on the resolution of Laplace and Poisson equations as well as Maxwell equation in quasi- Cartesian coordinate by using...
متن کاملThe Effect of Siliconizing and Borosiliconizing Processes on Microstructure and Morphology of Carbon Steel Surface Layers
A study for optimizing of siliconizing and borosiliconizing processes on carbon steels has been carried out. The process parameters, i.e, time and powder mixture, were considered for optimization of the case depth, surface quality and the hardness profile. Time and temperature of the processes were 4 hr and 950˚C, respectively. Powder mixture in siliconizing process was 2.5% ferrosilicon, 2.5%...
