    “…Therefore, this manuscript introduced a new type of Pt(3)Ni@C composite material as cathode working electrode based on the principle of volcanic catalytic curve. Through symmetric battery test, CV, polarization curves and impedance test, it was found that Pt(3)Ni@C composite material had good catalytic activity of lithium polysulfide to improve electrochemical kinetics. …”

    “…The aim of this paper was to study the simultaneous adsorption of heavy metals (Cu, Cd, Cr, Ni, Zn and Pb) from aqueous solutions using the zeolitic volcanic tuffs as adsorbents. The effect of thermal treatment temperature, particle size and initial metal concentrations on the metal ions sorption was investigated. …”

    “…We apply our injection model to Interferometric Synthetic Aperture Radar (InSAR) data from the ongoing unrest episode at Laguna del Maule (Chile) volcanic field that started in 2007. Using a grid search optimization, we minimize the misfit to the InSAR displacement data and vary the three parameters governing the analytical solution: the characteristic timescale τ (P) for magma propagation, the maximum injection pressure, and the inflection time when the acceleration switches from positive to negative. …”

    “…We provide the dataset associated with the research article “(40)Ar/(39)Ar ages of alkali feldspar xenocrysts constrain the timing of intraplate basaltic volcanism” Matchan et al. [1]. This dataset contains major element data for 15 large anorthoclase xenocrysts (‘megacrysts’) collected from six Pleistocene eruption centres (Mount Leura, Mount Shadwell, Mount Noorat, Mount Franklin, Lake Keilambete and The Anakies (East Cone)) in the basaltic Newer Volcanic Province of south-eastern Australia. …”
