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...
BiVO₄-assisted photocatalytic ozonation for efficient cyanide degradation in synthetic silver post-leaching effluentsNARA Subscribed
Cyanide is extensively used in hydrometallurgical leaching due to its strong metal-chelating ability, yet its acute toxicity raises major environmental concerns. This study evaluates photoactivated BiVO₄ synthesized by the sol–gel method and combined with ozone for the degradation of metal–cyanide complexes in alkaline matrices (pH 10.5) containing silver, copper, iron, lead, and zinc, representative of effluents from silver l...
Net primary productivity but not its remote‐sensing proxies predict mammal diversity in Andean‐Amazonian rainforestsNARA Subscribed
Tropical forests are disappearing, but we have a limited understanding of the factors driving species coexistence in mammal communities of old‐growth forest ecosystems. The total energy that is bound by plants is assumed to be a key factor determining mammalian species richness, but accurately measuring energy flows in complex ecosystems is difficult, and most studies therefore rely on remote‐sensing‐based surrogates of net pr...
Enhanced Cyanide Oxidation to Cyanate via Photocatalytic Ozonation: Comparing Sol–Gel and Hydrothermal Synthesis of BiVO4 CatalystsNARA Subscribed
Bismuth vanadate has been reported as a promising active semiconductor for visible light harvesting. However, the rapid recombination of charge carriers has limited its photocatalytic properties. As an alternative route to treat contaminated water containing cyanide ions, photoactivated BiVO 4 in combination with ozone has been investigated. BiVO 4 photocatalysts were synthesized by microwave-assisted hydrothermal method, as w...
