Nanotubes have significant portions of their atoms located at the surfaces and represent the future of biological devices. With such small dimensions, sensitivities and applications previously impossible are being made real. Not all nanomaterials are currently at the same level of proficiency, however. Carbon nanotubes are a mature, easily grown and controlled nanostructure, but boron nitride a...

We reported the optical and wettability properties of aligned zinc oxide micro/nanotube arrays, which were synthesized on zinc foil via a simple hydrothermal method. As-synthesized ZnO micro/nanotubes have uniform growth directions along the [0001] orientations with diameters in the range of 100-700 nm. These micro/nanotubes showed a strong emission peak at 387 nm and two weak emission peaks at...

Abstract In the last decades, increasing interest in piezoelectric material has opened new horizons electronic industries and alternative energy fields. this study, a (ZnO NSs–Na 2 Ti 6 O 13 ) were prepared from Zinc Oxid Nanosheets NSs) Disodium Hexa titanate (NTO). The dielectric, harvester performance, pyroelectric effect of ZnO NSs – NTO explored experimentally. Under different experimental...

In this study, a novel and facile approach for the synthesis of ternary boron carbonitride (B-C-N) nanotubes was reported. Growth occurred by heating simple starting materials of boron powder, zinc oxide powder, and ethanol absolute at 1150 degrees C under a mixture gas flow of nitrogen and hydrogen. As substrate, commercial stainless steel foil with a typical thickness of 0.05 mm played an add...

The potential of modified multiwallcd carbon nanotubes, as a solid-phase extraction sorbent for the simultaneous separation and preconcentration of zinc and thallium has been investigated. Zinc and thallium were adsorbed quantitatively onto modified multiwalled carbon nanotubes in the pH range of 3 6.5. Parameters influencing the simultaneous preconcentration of Zn(II) and Tl(I) ions such as pH...

A facile electrochemical method is developed to synthesize p-type Zn-doped α-Fe2O3 nanotube arrays that demonstrate excellent photoelectrochemical properties for water splitting.

Dye sensitized solar cell (DSSC) is the only solar cell that can offer both the flexibility and transparency. Its efficiency is comparable to amorphous silicon solar cells but with a much lower cost. This review not only covers the fundamentals of DSSC but also the related cutting-edge research and its development for industrial applications. Most recent research topics on DSSC, for example, ap...

Structure toxicity relationship analysis was conducted using principal component analysis (PCA) for a panel of nanoparticles that included dry powders of oxides of titanium, zinc, cerium and silicon, dry powders of silvers, suspensions of polystyrene latex beads and dry particles of carbon black, nanotubes and fullerene, as well as diesel exhaust particles. Acute in vitro toxicity was assessed ...
