Cubic copper ferrite CuFe2O4 nanopowders have been synthesized via a hydrothermal route using industrial wastes. The synthesis conditions were systematically studied using statistical design (Box–Behnken Program) and the optimum conditions were determined. The results revealed that single phase of cubic copper ferrite powders can be obtained at different(More)
Organisational transformation can be used interchangeably with terms like Organisational Restructuring, Business Process Reengineering (BPR), Business Process Improvement, Process Innovation, Business Transformation Cycle, Organisational Learning, and Total Quality Management (TQM). Transformation is a change of form, shape, character, condition, or nature.(More)
In this present work, zinc oxide (ZnO) nanostructures were successfully grown on titanium dioxide (TiO<sub>2</sub>) seed layer. To prepare a suitable site for ZnO nanostructures to grow, the TiO<sub>2</sub> seed layer was pre-coated on glass substrate by sol-gel spin-coating. The coated TiO<sub>2</sub> thin films were heated at different annealing(More)
TiO<sub>2</sub>:ZnO nanostructures thin films have been fabricated on glass substrates via sol-gel spin-coating technique for deposition of TiO<sub>2</sub> seed layer and solution-immersion method for growth of ZnO nanostructures. The layer of TiO<sub>2</sub> were annealed at various temperatures ranging from 350 to 500&#x00B0;C for 2 hours to examine the(More)
In this work, we report an optimisation of ultrasonic irradiation time on the synthesis of ZnO thin films to the photoluminescence (PL), surface morphologies and structural properties of ZnO on gold-seeded Si substrate. Surface morphology of the thin films was studied using field emission scanning electron microscope (FESEM). The photoluminescence and(More)
This Zinc Oxide (ZnO) nanorods films was synthesized with various Aluminum (Al) doping percentage deposited on ZnO seed layer using two step process sol-gel spin coating and immersion method. The Al doping was varied at different percentage from 0.6 at.% Al to 1.2 at.% Al. The morphology and electrical properties of ZnO nanorods were characterized using(More)
