This paper presents a comprehensive analysis of the lithic assemblage from Level G1 of El Cierro Cave (northern Spain), attributed to the Cantabrian Lower Magdalenian. The study comprises 2,829 items, including 2,800 knapped artefacts, six macrolithic tools and 23 unmodified pebbles. Lithic procurement is dominated by flint, followed by quartzite and minor amounts of quartz. Eleven flint types have been identified, with local...
Design and application of a TiO2/clay/Ag hybrid nanocomposite for environmental remediation of cytotoxic pharmaceuticalsNARA Subscribed
The contamination of water by cytostatic drugs poses a significant ecological risk. This study presents a novel TiO 2 /clay/Ag catalyst, synthesized through a simplified sol–gel method, and applied for the efficient removal of etoposide (ETP) from aqueous environments. A thorough characterization of the catalyst’s structural and morphological properties was carried out using various analytical techniques (XRD, FTIR, SEM, EDX,...
