Journal ArticleDOI
Synthesis, characterization and humidity sensing properties of Sr(II)-added BaAl2O4 composites
TL;DR: In this paper, the authors used X-Ray diffraction, scanning electron microscopy (SEM), FT-IR spectroscopy and nitrogen adsorption/desorption isotherms at 77 K to identify the structural phases, surface morphology, vibrational stretching frequencies and surface area of the composites.
Journal ArticleDOI
Effects of Ba doping on structural, morphological, optical, and photocatalytic properties of self-assembled ZnO nanospheres
S. K. Jesudoss,J. Judith Vijaya,N. Clament Sagaya Selvam,K. Kombaiah,M. Sivachidambaram,T. Adinaveen,L. John Kennedy +6 more
TL;DR: In this paper, a simple low-temperature co-precipitation method was employed to synthesize pure and Ba-doped self-assembled ZnO nanospheres.
Journal ArticleDOI
Effect of Ce and Cu co-doping on the structural, morphological, and optical properties of ZnO nanocrystals and first principle investigation of their stability and magnetic properties
TL;DR: In this article, the stability and magnetic properties of Ce and Cu co-doped ZnO were probed by first principle calculations, which revealed that all the compositions are single crystalline.
Journal ArticleDOI
Utilization of strontium added NiAl2O4 composites for the detection of methanol vapors
TL;DR: The results revealed that the sensitivity in detecting methanol vapor increased with increase in temperature up to 175 degrees C for the composites NiSA1 and NiSA6 while for the other composites up to 150 degrees C and thereafter decreased.
Journal ArticleDOI
Synergy effect in the photocatalytic degradation of textile dyeing waste water by using microwave combustion synthesized nickel oxide supported activated carbon
TL;DR: In this article, the photocatalytic activity was tested by the degradation of textile dye waste water (TDW) under UV light irradiation, which exposed prolonged light absorption in UV light region and hold better charge separation capability, respectively, as compared to pure NiO.
