The electro-catalytic activity with respect to water oxidation to form molecular oxygen of iron oxyhydroxide thin films on iron support surfaces in aqueous base is described. A mechanism involving iron surfaquo groups is proposed in excellent agreement with the kinetic data. It is shown that the rate determining step of the oxygen evolution reaction depends strongly on the conditions under whic...

China is a country with vast territory, but economic development and population growth have reduced the usable land resources in recent years. Therefore, reclamation by pumping and filling is carried out in eastern coastal regions of China in order to meet the needs of urbanization. However, large areas of reclaimed land need rapid drainage consolidation treatment. Based on past researches on h...

The presented article addresses the electro-osmotic peristaltic flow of a couple stress fluid bounded in an inclined asymmetric micro-channel. viscous dissipation, Joule heating and chemical reaction effects are employed simultaneously analysis. Heat mass transfer have been studied under large wavelength small Reynolds number. resulting nonlinear systems solved numerically. influence various do...

This article describes fretting behavior of zirconia and silicon nitride balls on an electro-deposited coating. Fretting tests are performed using a ball-on-flat configuration. The evolution of the kinetic friction coefficient is determined, along with slip ratio. Experimental results show that the steady-state friction coefficient between ceramic balls (Si₃N₄ and ZrO₂) and an electro-deposited...

: The present study evaluated the effect of integration electro-kinetic (EK) oxidation with sonication degradation diesel in a hydrocarbon contaminated wastewater. operational parameters including initial pH (3 - 9), (100 300 W), voltage (0.5 3 V/cm), and reaction time (60 150 min) were studied consecutively. highest total petroleum (TPH) destruction rate 40% was achieved at 5. Also, increasing...

Adipose stem cells (ASCs) have recently emerged as a more viable source for clinical applications, compared to bone-marrow mesenchymal stromal cells (BM-MSCs) because of their abundance and easy access. In this study we evaluated the regenerative potency of ASCs compared to BM-MSCs. Furthermore, we compared the dielectric and electro-kinetic properties of both types of cells using a novel Diele...
