Titanium oxide (rutile, TiO2) and zircon (ZrSiO4), known insoluble ceramic materials, are commonly used for coatings of implant materials. We investigate the release of zirconium, titanium, aluminum, iron, and silicon from different micron-sized powders of 6 powders of natural rutile (TiO2) and zircon (ZrSiO4) from a surface perspective. The investigation includes five different synthetic body ...

A versatile and convenient way to produce bioactive poly(lactic acid) (PLA) and poly(ε-caprolactone) (PCL) electrospun nanofibrous scaffolds is described. PLA and PCL are extensively used as biocompatible scaffold materials for tissue engineering. Here, biobased nano graphene oxide dots (nGO) are incorporated in PLA or PCL electrospun scaffolds during the electrospinning process aiming to enhan...

A novel brush-like electrode based on carbon nanotube (CNT) nano-yarn fiber has been designed for electrochemical biosensor applications and its efficacy as an enzymatic glucose biosensor demonstrated. The CNT nano-yarn fiber was spun directly from a chemical-vapor-deposition (CVD) gas flow reaction using a mixture of ethanol and acetone as the carbon source and an iron nano-catalyst. The fiber...

The tetragonal to monoclinic (t ! m) phase transformation during low temperature ( 100 8C) degradation (LTD) of yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) sintered in air at different temperatures was investigated. It is found that the sintering temperature affected the density, crystalline phase and microstructure of the sintered body, as well as the LTD behavior. Also, the ons...

Hafnium and zirconium oxide films were prepared by atomic layer deposition (ALD) from dialkylamido precursors. Water was used as the oxygen source. Nanolaminates of hafnium, zirconium and aluminum oxide were also prepared. Atomic force microscopy was used to characterize the surface morphology of 10–100 nm thick films grown from 501C to 3001C. X-ray diffraction was used to characterize the film...

Using electrospinning technique, well-aligned poly(azo-ether-imide) (PAEI) nano-fibers and PAEI/multiwalled carbon nanotube (MWCNT) nano-fibers were developed in this effort. Afterwards, polystyrene-b-poly (ethylene-ran-butylene)-b-polystyrene (SEBS) and polyimide-based nano-fiber films were casted. The as-prepared electrospun nanofibers acted as homogeneous reinforcement to enhance the tensile...
