GRAIN SIZE EFFECT ON PHOTOCATALYTIC PROPERTIES OF NANOCRYSTALLINE ZnO
The aim of this study represents the synthesis, characterization and photocatalytic activity determination of ZnO nanopowders synthesized using modified Pechini method. The obtained powders were characterized in what concerns their composition using X-ray diffraction, morphology using scanning electron microscopy and transmission electron microscopy and in what concerns the photocatalytic activ...
متن کاملInverse grain-size effect on twinning in nanocrystalline Ni.
A long-standing controversy exists between molecular dynamics simulations and experiments on the twinning propensity of nanocrystalline (NC) face-centered-cubic metals. For example, three-dimensional molecular dynamics simulations rarely observed twins in NC Ni, whereas experiments readily observed them. Here this discrepancy is resolved by experimental observation of an inverse grain-size effe...
متن کاملEffect of Grain Size and Hydrogen Passivation on the Electrical Properties of Nanocrystalline Silicon Films
The properties of mixed-phase (nanocrystalline/amorphous) silicon layers produced by reactive RF-sputtering are described. The chemical composition and nanostructure [i.e. nanocrystal (NC) size and volume fraction] of the films were studied by Rutherford backscattering spectroscopy (RBS) and micro-Raman spectroscopy, respectively. Samples with different fractions of the nanocrystalline phase an...
متن کاملMicrostructure and its effect on field electron emission of grain-size-controlled nanocrystalline diamond films
Nanocrystalline diamond films were grown by microwave plasma assisted chemical vapor deposition using N2 and CH4 as precursors. The microstructure of the films such as the diamond grain size, graphite content, and N incorporation, was controlled by introducing a small amount of hydrogen gas ~0–10 sccm! in the growth. Effects of the growth parameters on the film microstructure were investigated ...
متن کاملGrain size effect on the R-phase transformation of nanocrystalline NiTi shape memory alloys
This study investigated the effect of nanograins size on the R-phase transformation of a nanocrystalline Ti-50.2at%Ni alloy. The nanometric grain size was created by severe cold deformation and low temperature anneal. It was found that in the recrystallized state, nanograin sizes (<100 nm) was effective in suppressing the B2→B19’ martensitic transformation and revealing the B2↔R transformation....
