(2018). Both types of SD were modified by mixing the pre-weighed amounts with the acid or base solution, for 4 h at room temperature and for 2 h at 60 °C, in the following sequence: (1) 10 wt% aqueous solution of o-phosphoric acid (H3PO4), (2) 20 wt% aqueous solution of...
influence pertinent to the ion valency, the hydration of the surfaces and ions and the interacting surfaces charges. Our results concur with some reports in the literature on the effect of cations on adsorption of proteins54and stearic acid55onto the mica surface. Figure6illustrates all the propo...
Ring opening of extremely hydrophobic epoxides with water, amines, sodium azide and thiophenol was realized in the mixture solvent of water and 1, 4-dioxane under reflux condition. Hot water was believed to act as a mild Brønsted acid catalyst in the epoxide-opening reactions. ...
There is a lack of literature in quantitative assessment of functional groups’ role in heavy metal ions sorption. Moreover, the current surface modification techniques demand high heat/pressure, strong acid/base, or intensive oxidation/reduction reactions. This complex preparation process makes the car...
Currently, water oxidation electrocatalysts consist of noble-metal oxides, such as IrO2 and RuO2, because of their high stability in acid, small overpotential, and low Tafel value.2,3 However, the application of precious-metal-based catalysts on an industrial scale is cost prohibitive. To make...

More importantly, we demonstrate that pH-switchability of crude O/W emulsions can be achieved using either acid or base. However, at higher biosurfactant concentrations, switching the crude O/W emulsions using a base is incomplete. Furthermore, we also studied in this work the on-demand ...
