ABSTRACT Gadolinia-doped ceria (Ce0.9Gd0.1O1.95, GDC) electrolyte was fabricated by aqueous-based tape casting method for solid oxide fuel cells (SOFCs). The ceramic powder prepared by combustion synthesis was used with poly acrylic acid... more
ABSTRACT The impression creep behavior of the aging-treated Cu–6Ni–2Mn–2Sn–2Al alloy and its variants with separate additions of 0.3 wt.% Cr and 0.3 wt.% Zr was investigated in the temperature range 695–795 K and under constant punch... more
ABSTRACT Rare earth (RE) - doped ceria powders with a chemical composition of Ce1-x RExO2-x/2 (X: 0.1 and RE: Gd, Sm, Er, Pr, Nd and Y) were prepared by nitrate-fuel combustion method. The TG and DT analyses of the as-synthesized powders... more
ABSTRACT Multi-walled carbon nanotubes were homogenously dispersed into a magnesium alloy (AZ31) using friction stir processing. The microstructural features, mechanical behaviors such as microhardness and wear properties were... more
ABSTRACT La0.6Sr0.4Co0.2Fe0.8O3-Ce0.9Gd0.1O1.95 (LSCF–GDC) nanocomposite cathode material has been synthesized using a simple combustion process for intermediate and low temperature solid oxide fuel cells (SOFCs). The combusted cathode... more
ABSTRACT Size controlled cubic Fe3O4 nanoparticles in the size range 90-10 nm were synthesized by varying the ferric ion concentration using the oxidation method. A bimodal size distribution was found without ferric ion concentration and... more
ABSTRACT Fe3O4 nanoparticles were surface modified with Prussian blue (PB) and the nanoparticles were used for the removal of cesium (Cs) ion. The attachment of PB with the Fe3O4 and their morphology were explained based on the studies by... more
Abstract106Ru, 144Ce and 152+154Eu radiotracers sorption experiments (pH: 1–6) have been carried out with polycrystalline columnar/microcrystalline calcite and aragonite obtained from a stalagmite of Dharamjali cave, India. The different... more
The chemical synthesis of shape and composition controlled Fe based binary alloys has been challenging due to the highly oxidizing nature of Fe. Here, we report the physical properties of flower-like Fe50Co50 nanoparticles prepared by a... more
Rapid biosynthesis of silver nanoparticles from Gram +ve and Gram −ve bacterial strains and their hiogenicity dependent antibacterial and cytntoxicity.
Fast recombination of photoinduced charge carriers is a major problem in the case of semiconductor based photocatalysts, which must be solved for their potential application in photocatalysis. In this work, photostable CdS QDs/BiOI... more
