Intra-source provenance study on Monte Arci (Sardinia) obsidian by pXRF: Role of the data acquisition and analysis tools

Autor: Valentina Mameli, Marco Sanna Angotzi, Emanuele Farinini, Riccardo Leardi, Carlo Lugliè, Carla Cannas

Publikováno v: Heliyon, Vol 9, Iss 3, Pp e13958- (2023)

In this work, a detailed study of Monte Arci obsidian sub-sources using the increasingly accessible technique of pXRF is presented based upon a large dataset of 68 geological samples, for the development of X-ray fluorescence-based analytical standar

Germination and early seedling development of Helichrysum microphyllum Cambess. subsp. tyrrhenicum Bacch., Brullo & Giusso in the presence of arsenates and arsenites

Autor: Maria Enrica Boi, Marco Sanna Angotzi, Marco Porceddu, Elodia Musu, Valentina Mameli, Gianluigi Bacchetta, Carla Cannas

Publikováno v: Heliyon, Vol 8, Iss 9, Pp e10693- (2022)

Arsenate, As(V), and arsenite, As(III), are the most available arsenicals present in the soil solutions, in particular in mine polluted substrates, and cause several symptoms of toxicity in plants (like inhibition of seed germination and reduction of

Hard–Soft Core–Shell Architecture Formation from Cubic Cobalt Ferrite Nanoparticles

Autor: Marco Sanna Angotzi, Valentina Mameli, Dominika Zákutná, Fausto Secci, Huolin L. Xin, Carla Cannas

Publikováno v: Nanomaterials, Vol 13, Iss 10, p 1679 (2023)

Cubic bi-magnetic hard–soft core–shell nanoarchitectures were prepared starting from cobalt ferrite nanoparticles, prevalently with cubic shape, as seeds to grow a manganese ferrite shell. The combined use of direct (nanoscale chemical mapping vi

As(III, V) Uptake from Nanostructured Iron Oxides and Oxyhydroxides: The Complex Interplay between Sorbent Surface Chemistry and Arsenic Equilibria

Autor: Marco Sanna Angotzi, Valentina Mameli, Alessandra Fantasia, Claudio Cara, Fausto Secci, Stefano Enzo, Marianna Gerina, Carla Cannas

Publikováno v: Nanomaterials, Vol 12, Iss 3, p 326 (2022)

Iron oxides/oxyhydroxides, namely maghemite, iron oxide-silica composite, akaganeite, and ferrihydrite, are studied for AsV and AsIII removal from water in the pH range 2–8. All sorbents were characterized for their structural, morphological, textu

Self-Limitations of Heat Release in Coupled Core-Shell Spinel Ferrite Nanoparticles: Frequency, Time, and Temperature Dependencies

Autor: Shankar Khanal, Marco Sanna Angotzi, Valentina Mameli, Miroslav Veverka, Huolin L. Xin, Carla Cannas, Jana Vejpravová

Publikováno v: Nanomaterials, Vol 11, Iss 11, p 2848 (2021)

We explored a series of highly uniform magnetic nanoparticles (MNPs) with a core-shell nanoarchitecture prepared by an efficient solvothermal approach. In our study, we focused on the water dispersion of MNPs based on two different CoFe2O4 core sizes
