BACKGROUND Titanium is an inert metal that does not induce osteogenesis and has no antibacterial properties; it is proposed that hydroxyapatite coating can enhance its bioactivity, while zinc can contribute to antibacterial properties and improve osseointegration. AIMS A nano-sized hydroxyapatite-zinc coating was deposited on commercially pure titanium using an electro-chemical process, in or...

Hierarchically structured mixture models are studied in the context of data analysis and inference on neural synaptic transmission characteristics in mammalian, and other, central nervous systems. Mixture structures arise due to uncertainties about the stochastic mechanisms governing the responses to electro-chemical stimulation of individual neurotransmitter release sites at nerve junctions. M...

The electro-optic properties of 1.3 mm self-assembled InAs=GaAs quantum dots grown by metal organic chemical vapour deposition are reported. The linear and quadratic electro-optic coefficients are 2.4 10 11 m=V and 3.2 10 18 m=V, respectively, which are significantly larger than those of GaAs bulk materials. Also, the linear electro-optic coefficient is almost comparable to that of lithium niob...

The recycling of sodium borohydride poses a huge challenge to the drive towards hydrogen economy. Currently, mechano-chemical, thermo-chemical and electrochemical are only reported methods metaborate into borohydride. Much attention has been devoted mechano-chemical reduction, but little focus methods. This review describes behaviour (BH4−) (BO2−) anions in alkaline solutions. BH4− is stabilize...

The present study reports synthesis of MOWS2 nanocomposite followed by its characterization using energy dispersive X-ray spectroscopy (EDS), X-Ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). Chronoamperometry (CHA), differential pulse voltammetry (DPV), and cyclic voltammetry (CV) have been used to examine electro-chemical behaviors of sulfite on MOWS2...
