A monoclinic zirconia coating with a nanostructural surface was prepared on the Ti-6Al-4V substrate by an atmospheric plasma-spraying technique, and its microstructure and composition, as well as mechanical and biological properties, were investigated to explore potential application as a bioactive coating on bone implants. X-ray diffraction, transmission electron microscopy, scanning electron ...

The elemental and structural features of the nitride nanostructured coating produced by vacuum arc evaporation from high-entropy cathode TiHfVNbZr were studied. Using of the complementary methods of elemental analysis (RBS, SIMS and GDMS) allowed to carry out a comprehensive analysis of the elemental composition, namely to determine the chemical composition of the surface layer, to establish th...

A composite of graphene and carbon nanotubes has been synthesized and characterized for application as supercapacitor electrodes. By coating the nanostructured active material of Co(OH)2 onto one electrode, the asymmetric supercapacitor has exhibited a high specific capacitance of 310 F g-1, energy density of 172 Wh kg-1 and maximum power density of 198 kW kg-1 in ionic liquid electrolyte EMI-T...

This study was conducted to evaluate the bioactivity of manganese-incorporated TiO2 (Mn-TiO2) coating prepared on titanium (Ti) plate by plasma electrolytic oxidation (PEO) technique in Ca-, P- and Mn-containing electrolytes. The surface topography, phase and element compositions of the coatings were investigated using scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispe...

The reflection of light at interfaces limits the performance of optical components. An anti-reflection (AR) coating layer is often applied to improve the optical transmittance. Besides the commonly used singleor multi-layer coatings reducing the reflection, subwavelength nanostructures have gained more attention as an effective AR feature. A wide choice of materials can be nanostructured withou...

The realization of next-generation portable electronics and integrated microsystems is directly linked with the development of robust batteries with high energy and power density. Three-dimensional micro- and nanostructured electrodes enhance energy and power through higher surface area and thinner active materials, respectively. Here, we present a novel approach for the fabrication of hierarch...

The detection of photons underpins imaging, spectroscopy, fibre-optic communications and time-gated distance measurements. Nanostructured materials are attractive for detection applications because they can be integrated with conventional silicon electronics and flexible, large-area substrates, and can be processed from the solution phase using established techniques such as spin casting, spray...

Heterostructured powders composed of microcrystalline (mc-) BaTiO3 and SrTiO3 cores coated with nanostructured (ns-) TiO2 shells were prepared using a solegel method. The influences of annealing temperature, coating thickness, cocatalyst loading, and core size on photocatalytic hydrogen production were experimentally determined. The amount of hydrogen produced depends on the annealing temperatu...
