Electrocrystallization of hydroxyapatite (HAp) on titanium was achieved by cathodic polarization in solution containing calcium nitrate and ammonium dihydrogen phosphate. The composition and pH of the bath were found to significantly affect the nature and surface morphology of the deposit. The effect of bath temperature was also studied. X-ray diffraction(More)
The basic calcium phosphate mineral, hydroxyapatite (HAP) (Ca10(PO4)6(OH)2)), is the prototype of one of the major constituents of bone and teeth. Thin layers of HAP were coated on the surface of type 316L stainless steel by electrophoretic deposition (EPD) from a 2.5% suspension in isopropyl alcohol, and this was followed by vacuum sintering at 800uC for 1(More)
Body Area Network (BAN) is a network of wireless medical sensors, deployed on a person, for enabling pervasive, individualized, and real time health management. Securing inter-sensor communications within BANs is essential for preserving not only the privacy of health data but also for ensuring safety of healthcare-delivery. The proposed technique presents(More)
Surface modified ZnO nanomaterial is widely used in the field of bioimaging worldwide due to its optical properties, electronic characteristics and biocompatibility. Fluorescent enhanced, Polyquaternium-7(PQ7) capped, ZnO hexagonal nano disks (ZnO-PQ7) were synthesised by simple wet chemical method. The structural and optical properties of ZnO-PQ7 hexagonal(More)
Mentha piperita L. (Peppermint) is a perennial glabrous and strongly scented herb belonging to family Lamiaceae. The plant is aromatic, stimulant and used for allaying nausea, headache and vomiting. Its oil is one of the most popular widely used essential oils in food products, cosmetics, pharmaceuticals, dental preparations, mouthwashes, soaps and(More)
Nickel-tungsten alloys were electrodeposited on stationary working electrodes from a nickel sulfate, sodium tungstate, and tri-sodium citrate-based bath under different operating conditions. The microstructure of the deposits was studied by X-ray diffraction, the morphology by scanning electron microscopy and atomic force microscopy, and the approximate(More)
