Hydrothermal synthesis of Mn2+ doped titanate nanotubes: Investigation of their structure and room temperature ferromagnetic behavior
(Elsevier Science Bv, Amsterdam, 2019)
Hydrothermal synthesis of Mn2+ doped titanate nanotubes (TNTs), which exhibited room temperature ferromagnetism (RTFM), is reported. Dispersions of 1 and 5 at.% Mn2+ doped anatase TiO2 nanocrystals were used as precursors. ...
Polyphosphate glass as fertilizer for plant seedlings / Efekat primene polifosfatnog stakla u supstratima za gajenje cveća i povrća
(Inženjersko društvo za koroziju, Beograd, 2019)
Due to the dissolution properties the phosphate glasses can be promising materials for the development of new ecologically safe fertilizers. The complex polyphosphate glass with a molar ratio (M2O + MO)/P2O5 >1 and addition ...
Chamomile Floricolous Downy Mildew Caused by Peronospora radii
(Amer Phytopathological Soc, St Paul, 2019)
Floricolous downy mildews (Peronospora, oomycetes) are a small, monophyletic group of mostly inconspicuous plant pathogens that induce symptoms exclusively on flowers. Characterization of this group of pathogens, and ...
Comparative morphological and crystallographic analysis of copper powders obtained under different electrolysis conditions
(Elsevier Science Bv, Amsterdam, 2019)
