The article reveals for the first time features of nanoparticle morphology, phase compositions, and their changes when heating FePt CoPt nanoalloys. Nanoparticles were obtained by co-reduction precursor solution mixtures with hydrazine hydrate. found a complex methods X-ray diffraction (in situ XRD scattering), TEM HR, cyclic voltammetry. In addition, adsorbometry results obtained, stability different nanocluster structures was calculated molecular dynamics method. There only FCC solid...
Herein, nanostructured composites (NSCs) based on multiwalled carbon nanotubes (MWCNTs) filled with the individual (IH) and mixed (MH) Ni/Co hydroxides nanoparticles are prepared an influence of NSC morphology texture their electrical capacitance is considered. It found that MWCNTs have a channel diameter (2−5 nm), external (18−23 wall width (2−12 nm). In NSCs obtained by precipitation from chloride aqueous solutions in alkaline medium, filler particles formed as nanocrystallites inside...
Calculations of the total energy Fe-Pt nanoclusters, corresponding in phase diagram to compositions FePt, FePt3 intermetallics and possessing either characteristic structures L10 L12, respectively, or non-characteristic disordered structure A1, as well various particle habits (cuboctahedra, icosahedra) are carried out by molecular dynamics for first time. The dependences cluster stability on their size temperature plotted, along with schemes transformations morphology dependence melting...
The formation of paramagnetic centers in potassium picrate under irradiation at low temperature was investigated. heating irradiated 77 K crystal to room results - 2,6-dinitro-para-quinone radicals, ortho- and para-iminoxyl radicals atomic oxygen. These products are formed temperature.
In this work, the thermal stability of FePt nanoclusters different habitus is considered using molecular dynamics method with multiparticle interaction potential MEAM-2NN. Three variants determining temperatures structural disorder/melting these are presented: by normalised per atom total energy clusters from temperature, approximation curves linear sections, intersection points which were used to determine disorder temperatures; second mean-square displacement atoms; third visualisation...
