    - Advanced Energy Materials - Rok 2015

    ZnFe2O4 (ZFO) Li-ion batteries (LIBs) represent a reliable, affordable, and safe energy storage technology for use in portable application. However, current LIB active materials (graphite, lithium/transition metal spinel or layered oxides, olivine structures) can store only limited energy since they rely on insertion storage based on solid-state host-guest interactions. Moreover, performances and durability of the cells are strongly...

    - JOURNAL OF ALLOYS AND COMPOUNDS - Rok 2023

    Bulk and nanostructurized lanthanum-cobalt spinels have attracted a lot of interest from researchers, due to their unique physical and chemical properties as well as functionalities, which are interesting for biomedical and electronic industries. In this manuscript we show that introducing small lanthanum (La3+) content can tune magnetic, electronic and cytotoxic properties of the CoFe2− xLaxO4 system (x ≤ 0.1). The mechanisms...

  • The XAS spectra of O-K edges, M-L edges and Ce-M edges in Ce0.9M0.1O2

    Dane Badawcze
    embargo - seria: Ceria

    The dataset consists of XAS spectra of O-K edges, M-L edges of Ce0.9M0.1O2 (where M=Mn, Fe, Co, Ni, Cu) synthesised by reverse microemulsion method. XAS spectra were collected at PIRX beamline in SOLARIS National Synchrotron Radiation Centre. Measurements were perfomed under ultra high vacuum in total electron yield (TEY) mode.
