Abstract: High quality silver-iron titanate nanoparticles are synthesized using an ilmenite source. The silver-iron titanate nanoparticles were characterized using various analytical techniques. As compared to prior art methods, the disclosed methods provide for the simple, cost-effective synthesis of relatively high-quality silver-iron titanate nanoparticles. The silver-iron titanate nanoparticles can be used in a variety of important agricultural, industrial, and hygienic uses, including in the important area of plant tissue culture explant sterilization.

Abstract: A macronutrient sustained release composition for a plant locus having nitrogen containing macronutrient compound adsorbed on the surface of hydroxyapatite phosphate nanoparticles, and a process for preparation thereof. The macronutrient adsorbed hydroxyapatite phosphate nanoparticles are encapsulated within cavities present in wood such that the biodegradation of the wood releases the adsorbed macronutrient compounds in a slow and sustained manner to the soil. Further, the macronutrient particles are encapsulated within the cell cavities of wood and wood is coated with cellulose modified hydroxyapatite phosphate nanoparticles such that the rupture of the nanocoating initiates the nitrogen release followed by the biodegradation of the wood releases the rest of the adsorbed macronutrient compounds in a slow and sustained manner to the soil.

Abstract: A macronutrient sustained release composition for a plant locus containing a nanocomposite wherein a nitrogen containing macronutrient compound adsorbed on the surface of hydroxy apatite phosphate nanoparticles is intercalated within the interlayer spacing of a nanoclay. The nanocomposite containing the adsorbed macronutrient compounds is slowly released in a sustained manner when contacted with an acidic soil.
