The Late Glacial (14 700–11 700 cal BP) is a key climate period marked by rapid but contrasted changes in the Northern Hemisphere. Indeed, regional climate differences have been evidenced during the Late Glacial in Europe and the northern Mediterra

International Journal of Nanotechnology, Inderscience, 2012, 9 (3/4/5/6/7), pp.204. ⟨10.1504/IJNT.2012.045327⟩

The adsorption capacity of a natural nanostructured clay (sepiolite) for the inorganic species: Ni2+ and As(V) has been studied using a batch method. The different parameters affecting sorption such as the mass of adsorbent, contact time, sorbate con
