Abstract The interfacial microstructure and hardness of cladding plates produced by explosive welding between magnesium alloys having different aluminum concentrations A6005C alloy were investigated. Further, measurements residual stress at the interface performed. In all plates, bonding had a wavy shape. Adiabatic shear bands formed on side deformation twins appeared due to impact welding. Mic...

The spatial redistribution of the charged point defects under direct-current (DC) biasing can have significant implications for electroceramic device performance and lifetime [1,2]. The transport behavior of point defects is regulated by the boundary conditions of the electrodes, which can block ion transfer across the interface to varying degrees. When the electrodes are impermeable to mass tr...

Alcohols, including branched and straight ones, have been used extensively in industrial processes to enhance the interface effect. Amongst these, methyl isobutyl carbinol (MIBC) is particularly popular due to the superior performance in mineral flotation. The interfacial behavior of MIBC at the air/liquid interface has been investigated employing foaminess, thin aqueous film and zeta-potential...

An evanescent wave variant of broadband cavity enhanced absorption spectroscopy using a supercontinuum light source has been used to detect electrogenerated species at the silica-water interface. In proofof-concept experiments [IrCl6] was produced by electro-oxidation of [IrCl6] in a thin layer electrochemical cell. Diffusion of the Ir(IV) across the cell to a silica interface was monitored yie...

Batch foam separation has been employed to separate Saccharomyces carlsbergensis cells from their broth without the use of any external surface-active agent. A model has been developed to predict the foamate cell concentration as well as the variation of cell concentration in the bulk liquid in the foam column as a function of time. The model assumes a linear equilibrium relation between the ce...

A parametric finite element approximation of incompressible two-phase flow with soluble surfactants is presented. The Navier–Stokes equations are coupled to bulk and surfaces PDEs for the surfactant concentrations. At the interface adsorption, desorption and stress balances involving curvature effects and Marangoni forces have to be considered. A parametric finite element approximation for the ...

Surface light scattering (SLS) by capillary waves was used to investigate the adsorption behavior of non-ionic sugar surfactants at the air/liquid interface. SLS by the subphase (water) followed predictions from hydrodynamic theory. The viscoelastic properties (surface elasticity and surface viscosity) of monolayers formed by octyl beta-glucoside, octyl alpha-glucoside, and 2-ethylhexyl alpha-g...

Variable-density groundwater flow models are often used to understand the complex nature of coastal groundwater systems. Hydrodynamic dispersion is a difficult process to represent with a model because of spatially varying hydraulic conductivity and temporally varying hydrologic boundary conditions. Temporal variations in water levels, for example, that occur in the field are often averaged int...

Thick oxides deposited on 4H-SiC epilayers to form Metal-Oxide-Semiconductor capacitors have been studied by Capacitance-Voltage (C-V) and Thermally Stimulated Ionic Current (TSIC) measurements. The very negative flatband voltage VFB in regards the theoretical value indicates presence oxide of a large number positive charges. Positive mobile charges are responsible for part this unusual VFB, as...

A stable growth mode of a single dendritic crystal solidifying in an undercooled ternary (multicomponent) melt is studied with allowance for forced convective flow. The steady-state temperature, solute concentrations and fluid velocity components are found two- three-dimensional problems. stability criterion the total undercooling balance derived accounting surface tension anisotropy at solid-m...
