DOI: 10.1016/j.colsurfa.2018.03.001
Abstract: Abstract The adsorption of corn starch at high purity hydrophobic minerals, HOPG and talc, was found to be due to hydrophobic interaction. These results suggest that the previous thinking, in which acid-base interactions between hydroxylated… read more here.

DOI: 10.1016/j.watres.2019.115240
Abstract: Advanced oxidation treatment processes used in various applications to treat contaminated soil, water, and groundwater involve powerful radical intermediates, including hydroxyl radicals (•OH). Inefficiency in •OH-driven treatment systems involves scavenging reactions where •OH react with… read more here.
