Recently, the synthesis, properties, modifications, and applications of TiO2 nanomaterials have attracted much research attention. Here, based on extensive density functional theory calculations, we explored the stability, electronic structures and optical absorption properties of single-walled TiO2 nanotubes (SWTONTs) and TiO2 nanotube arrays (TONTAs), which are constructed from anatase TiO2(1...

TiO2 nanotube arrays were synthesized by anodization of Ti metal sheets followed by thermal annealing at elevated temperatures from 400 to 600 C. Scanning electron microscopic measurements showed that dense arrays of nanotubes were produced with the inner diameter about 100 nm, wall thickness 35 nm, and length about 10 lm. X-ray diffraction measurements showed that the as-prepared nanotubes wer...

Standard sacrificial template synthesis allows metal oxide nanotubes to be produced from ZnO nanowires. In spite of their high interest in several technological fields, the low surface area of these nanotubes is a drawback for most applications. Here we report for the first time the sacrificial template synthesis of stainless steel wire-mesh (SSWM) supported metal oxides of high technological i...

Studies of carbon nanotube (CNT) based composites have been unable to translate the extraordinary load-bearing capabilities of individual CNTs to macroscale composites such as yarns. A key challenge lies in the lack of understanding of how properties of filaments and interfaces across yarn hierarchical levels govern the properties of macroscale yarns. To provide insight required to enable the d...

TiO2 has been investigated extensively as an active resistive switching (RS) material for resistive random access memory. In this letter, single-crystal anatase-TiO2 thin films fabricated on silicon by atomic layer deposition are used to realize highly stable and clean bipolar RS behavior with a record high ON/OFF ratio (∼107) and low leakage current in the highresistance state. The switching c...

Degradation of Acid Red 4 (AR4) by photocatalytic processes with TiO2 nanotube arrays (TNTs) of various dimensions was carried out in this study. TNTs was fabricated by the anodization of titanium foil in electrolyte containing fluoride. The dimension and the induced photocurrent of TNTs were determined by a field-emission scanning electron microscopy and a potentialstat/galvanostat, respective...

Metal oxide materials are widely used for gas sensing. Capable of operating at elevated temperatures and in harsh environments, they are mechanically robust and relatively inexpensive and offer exquisite sensing capabilities, the performance of which is dependent upon the nanoscale morphology. In this paper we first review different routes for the fabrication of metal oxide nanoarchitectures us...
