Journal ArticleDOI
Synthesis and TEM study of nanoparticles and nanocrystalline thin films of silver by high pressure sputtering
TL;DR: In this paper, the authors discuss the conditions necessary for the synthesis of nanocrystalline silver both in the thin film and powder forms, and the growth pattern and morphology of the sputter-deposited nano-grains were studied in detail using transmission electron microscopy and atomic force microscopy.
Journal ArticleDOI
Phase separation in immiscible silver–copper alloy thin films
TL;DR: In this paper, the columnar grains of the as-deposited Ag-Cu films were shown to be composed of nanocrystalline grains of a single alloyed face-centered cubic (fcc) phase.
Journal ArticleDOI
Preparation of ultrafine high density gamma ferric oxide using aerosol OT microemulsions and its characterization
TL;DR: In this paper, it has been observed that the product is always a mixture of alpha and gamma ferric oxides which were characterized by TGA, DTA and XRD studies.
Journal ArticleDOI
Dielectric properties of oriented thin films of PbZrO3 on Si produced by pulsed laser ablation
Soma Chattopadhyay,Pushan Ayyub,V. R. Palkar,Manu Multani,S. P. Pai,S. C. Purandare,R. Pinto +6 more
TL;DR: In this paper, a single phase, perfectly c-axis oriented thin films of PbZrO3 were deposited on Si(100) substrates by pulsed laser ablation at 700°C and the growth conditions (substrate temperature, ambient oxygen pressure, and laser energy density) were optimized and the morphology of the films studied by scanning electron microscopy and atomic force microscopy.
Journal ArticleDOI
Efficient photocatalytic degradation of rhodamine B dye by aligned arrays of self-assembled hydrogen titanate nanotubes
TL;DR: In this article, an aligned array of hydrothermally grown, multiwalled hydrogen titanate (H2Ti3O7) nanotubes, anchored to both faces of a metallic Ti foil, was used as an efficient photocatalyst.
