“…Following Tournassat et al [52], we focus on smectites because these ubiquitous clay mineral nanoparticles play important roles in soil chemistry [55,56], soil mechanics [57], fault friction [58,59], materials chemistry [60], landfill and contaminated site isolation [61,62], high-level radioactive waste storage [63,64], CO 2 sequestration [65,66], and gas hydrate stability in marine sediments [67,68]. Their adsorption properties for small inorganic ions have been extensively studied using macroscopic [55,56,69], spectroscopic [24,25], and MD simulation techniques [18,35,37,45,49,52].…”
