among the most common types of problematic soils, are probably the expansive ones. one of the modern methods of strengthening and improving the soil in place is the use of electro-osmotic improving treatment. this paper presents the design of an apparatus suitable for electro-osmotic treatment. a soil sample of a high expansive potential was compacted and the effect of electro-osmotic treatment...

The electro-oxidation of methanol to formate is an interesting example the potential use renewable energies add value a biosourced chemical commodity. Additionally, can replace sluggish oxygen evolution reaction when coupled hydrogen or electroreduction other biomass-derived intermediates. But cost-effective realization these schemes requires development efficient and low-cost electrocatalysts....

Pd-based electro-catalysts are a key component to improve the methanol oxidation reaction (MOR) kinetics from alcohol fuel cells. However, performance of such catalysts is degraded over time. To understand microstructural/atomic scale chemical changes responsible for an effect, scanning (transmission) electron microscopy measurements and atom probe tomography were performed after accelerated de...

The effect of different parameters such as temperature, type catalyst and hydrogen peroxide (H2O2) concentration on the degradation pollutants in water by Fenton-like oxidation was studied using Box-Behnken design (BBD), an effective statistical model to experiments. Concerning heterogeneous catalysts, three bimetallic catalysts with lanthanum (La) iron (Fe) ion-exchanged into zeolites (NaY ZSM...

groundwater makes up an important part of global freshwater resources, though it is often threatened by overuse of natural resources along with abundant production of wastes in modern society. this study aims to investigate the removal of three heavy metals including nickel, cadmium, and lead from groundwater via electrocoagulation, a suitable method for treatment of water-soluble compounds, de...
