Horizontal low gradient magnetophoresis behaviour of iron oxide nanoclusters at...
Benelmekki, M.; Caparrós Vásquez, Cristina Maria; Montràs, A.; Gonçalves, Renato Ferreira; Lanceros-Méndez, S.; Martínez, Ll.In this work the use of Horizontal Low Gradient Magnetic Field (HLGMF) (<100T/m) for filtration, control and separation of synthesized magnetic nanoparticles (NPs) is investigated. The characteristics of the suspension, size and type of the NPs are considered and discussed. For these purposes, Fe2O3 silica coated nanoclusters of about 150 nm are synthesized by co-precipitation, monodispersion and silica coatin...
Study on oxidation layer of size controlled Nickel nanoparticles
Coutinho, Paulo J. G.; Xuriguera, E.; Benelmekki, M.; Segarra, M.; Martínez, Ll.Documento submetido para revisão pelos pares. A publicar em Nanoscale Research Letters. ISSN 1556-276X ; Research on morphology and structure of oxidation layer of Ni nanoparticles (NPs) is reported. Ni NPs were obtained by wet chemical solution method and their size controlled in the nickel nucleation step using a non-ionic surfactant. Particles were about 50nm in size and polycrystalline. Combining high-angl...
