Journal ArticleDOI
Structural, optical and EPR studies on ZnO:Cu nanopowders prepared via low temperature solution combustion synthesis
A. Jagannatha Reddy,M.K. Kokila,H. Nagabhushana,R.P.S. Chakradhar,C. Shivakumara,J.L. Rao,B.M. Nagabhushana +6 more
TL;DR: In this paper, powder X-ray diffraction (PXRD) analysis, scanning electron microscopy (SEM), Transmission electron microscope (TEM), Fourier transformed infrared (FTIR) spectroscopy, photoluminescence (PL) and Electron Paramagnetic Resonance (EPR) measurements were used for characterization.
Journal ArticleDOI
Effect of wettability and surface roughness on ice-adhesion strength of hydrophilic, hydrophobic and superhydrophobic surfaces
TL;DR: In this article, the anti-icing properties of hydrophilic, hydrophobic and super-hydrophobic surfaces/coatings were evaluated using a custom-built apparatus based on zero-degree cone test method.
Journal ArticleDOI
Combustion synthesis, characterization and Raman studies of ZnO nanopowders
A. Jagannatha Reddy,M.K. Kokila,H. Nagabhushana,J.L. Rao,C. Shivakumara,B.M. Nagabhushana,R.P.S. Chakradhar +6 more
TL;DR: Spherical shaped ZnO nanopowders (14-50 nm) were synthesized by a low temperature solution combustion method in a short time <5 min and SEM micrographs reveal that the particles are spherical in shape and the powders contained several voids and pores.
Journal ArticleDOI

R. Hari Krishna,R. Hari Krishna,B.M. Nagabhushana,H. Nagabhushana,N. Suriya Murthy,S.C. Sharma,C. Shivakumara,R.P.S. Chakradhar +7 more
TL;DR: In this article, the effect of calcination temperature on the structural, photoluminescence (PL), and thermoluminecence (TL) properties of nanophosphors has been investigated.
Journal ArticleDOI
Effect of Li+-ion on enhancement of photoluminescence in Gd2O3:Eu3+ nanophosphors prepared by combustion technique
N. Dhananjaya,N. Dhananjaya,H. Nagabhushana,B.M. Nagabhushana,B. Rudraswamy,C. Shivakumara,R.P.S. Chakradhar +6 more
TL;DR: In this paper, Li+-doped Gd2O3:Eu3+ nanophosphor was synthesized by low-temperature solution combustion technique in a short time.
