cotio3-clay nano-composites were synthesized via a conventional sol-gel method; the gel was calcinated at 500 - 800°c for 2 hours. the presence of rhombohedra phase of cotio3 in clay matrix was confirmed by xrd, ftir, sem. cobalt titanate-clay nano-composites were prepared with 5-20%(w/w) by sol-gel method. the spectra results were investigated at 20% (w/w) concentration .the optimum condition ...
Recently, large-scale agriculture has led to increasing crop production. To increase productivity in cropping systems, attempts have been made make nano-fertilizers and deliver them the crops by extension of nanotechnology. Hence, might be defined as nanoparticles that may directly assist supplying essential nutrients for productivity. Seed germination is first most susceptible stage plant’s gr...
ABSTRACT. At various calcination temperatures 450, 550 and 650 °C, zinc oxide nanoparticles were produced. Calcinated ZnO has high surface area as the BET was 119.12 m2g–1 average particle radius calculated to be 1.16 nm. The dimension of crystallites straining in nanoparticles' diffraction peaks remained measured. Williamson–Hall (W–H) technique besides size–strain approach stayed used. For ea...
Calcinated egg shell (Egg-CaO), of which the main component is calcium oxide, was evaluated in the forms of powder and aqueous solutions for their efficacies as disinfectants against avian influenza virus (AIV), Newcastle disease virus (NDV), infectious bursal disease virus (IBDV), Salmonella Infantis and Escherichia coli. Egg-CaO powder inactivated these viruses within 3 min in the presence of...
Batch-type experiments were used to study competitive As(V) and P sorption on various soils and sorbent materials. The materials assayed were a forest soil, a vineyard soil, pyritic material, granitic material, coarsely and finely ground mussel shell, calcinated mussel shell ash, pine sawdust and slate processing fines. Competition between As(V) and P was pronounced in the case of both soils, g...
