        Magnetic properties of acicular ultrafine iron particles 

        Universidade Estadual Paulista (Unesp); Universidade de São Paulo (USP); Inst Ciência Mat; Univ Antwerp (Institute of Electrical and Electronics Engineers (IEEE), 2002-09-01)
        Magnetic properties of acicular (similar to60 and similar to200 nm) iron particles, obtained by reduction of alumina-coated goethite particles, are reported. X-ray diffraction and Mossbauer spectroscopy showed that the ...

        Magnetic properties of acicular ultrafine iron particles 

        Varanda, L. C.; Goya, G. F.; Morales, M. P.; Marques, RFC; Godoi, RHM; Jafelicci, M.; Serna, C. J. (Institute of Electrical and Electronics Engineers (IEEE), 2014)

        MAGNETIC-PROPERTIES AND GIANT MAGNETORESISTANCE IN MELT-SPUN CO15CU85 ALLOYS 

        YU, RH; ZHANG, XX; TEJADA, J; KNOBEL, M; TIBERTO, P; ALLIA, P (Iop Publishing LtdBristolInglaterra, 1995)

        Ultrafine-grained Al composites reinforced with in-situ Al3Ti filaments 

        Krizik, Peter; Balog, Martin; Nosko, Martin; Castro Riglos, Maria Victoria; Dvorak, Jiri; Bajana, Oto (Elsevier Science Sa, 2016-01)
        Ultrafine-grained (UFG) Al matrix composites reinforced with 15 and 30vol% in-situ Al3Ti filaments were fabricated by extrusion of Al-Ti powder mixtures followed by solid-state reactive diffusion. Fine Al powder particles ...

        On the thermal stability of ultrafine-grained Al stabilized by in-situ amorphous Al2O3 network 

        Balog, Martin; Hu, Tao; Krizik, Peter; Castro Riglos, Maria Victoria; Saller, Brandon D.; Yang, Hanry; Schoenung, Julie M.; Lavernia, Enrique J. (Elsevier Science Sa, 2015-11)
        Bulk Al materials with average grain sizes of 0.47 and 2.4μm, were fabricated by quasi-isostatic forging consolidation of two types of Al powders with average particle sizes of 1.3 and 8.9μm, respectively. By utilizing the ...

        Age Hardening in Ultrafine-Grained Al-2 Pct Fe Alloy Processed by High-Pressure Torsion 

        Cubero-Sesin, Jorge; Horita, Zenji (Springer Boston, 2015-06)
        A cast Al-2 wt pct Fe alloy was processed by high-pressure torsion (HPT) at room temperature and then subjected to artificial aging at temperatures of 373 K and 473 K (100 °C and 200 °C). The aging behavior was studied by ...

        Estudo de aproveitamento econômico das lamas de uma mineração de ferro, através de concentração por flotação catiônica reversa 

        Luciano Rocha (Universidade Federal de Minas GeraisUFMG, 2008-02-22)
        High grade deposits were mined in the early stages of the activity. No attention was paid to maximizing the use of the deposits. Even nowadays, millions of tons of useful minerals are disposed every year into tailings ...

        Alcohol induced ultra-fine dispersion of Pt on tuned morphologies of CeO2 for CO oxidation 

        Meher, Sumanta Kumar; Cargnello, Matteo; Troiani, Horacio Esteban; Montini, T.; Ranga Rao, G.; Fornasiero, Paolo (Elsevier Science, 2013-02)
        Controlling the structures of supports and supported phases is important for catalytic applications where synergic effects can play a main role. In this context, we present versatile methods for suitable microstructurization ...

        Atmospheric particulate pollution in South American megacities 

        la Colla, Noelia Soledad; Botté, Sandra Elizabeth; Marcovecchio, Jorge Eduardo (National Research Council Canada-NRC Research Press, 2021-04-15)
        Air pollution is one of the major problems caused by urban growth, and both industrial and automobile emissions have been the main causes of air quality deterioration in cities since the beginning of the 20th century. ...
