in order to fabricate transparent tio2 nanotube dye-sensitized solar cells, anodically growth nanotube membranes are detached from ti substrate by a re-anodization method. the membranes are transferred on fto glass by two different methods. at the first one, 100mm ti-isopropoxide is used to make tio2 nanoparticles for adhering tio2 nanotube membranes to fto and in the second one a commercial ti...

In this work, we present a novel fabrication process of lateral porous silicon membranes with tunable pore size and porosity for microfluidic applications. Our proposed method relies on the fact that the formation of porous silicon by anodization is highly dependent on the dopant concentration (Fig. 1) [1]. Here, we use ion implantation to manipulate the local dopant concentration in order to c...

The purpose of this paper is to evaluate the characteristics corrosion protection stainless steel substrates coated with silica by electrophoresis pulsed direct current (PDC) and constant (CDC) anodization. Electrophoresis was carried out using sol from sodium silicate solution as an electrolyte solution. Stainless functioned anode carbon a cathode electrode distance 2 cm. amplitude, duty cycle...

We combine electron beam lithography and masked anodization of epitaxial aluminium to define tunnel junctions via selective oxidation, alleviating the need for wet-etch processing or direct deposition dielectric materials. Applying this technique Josephson in proximity induced superconducting Al-InAs heterostructures, we observe multiple Andreev reflections transport experiments, indicative a h...

TiO2 based photonic materials (TiO2 PMs) with hierarchical top-nanonet/bottom-nanotube structures were fabricated by a facile two-step electrochemical anodization method. The TiO2 PMs demonstrated multiple band light trapping activity not only in the ultraviolet and visible regions, but also in the near infrared region.

A novel nanocomposite TiO(2) film consisting of a bamboo leaf-like nano TiO(2) layer on a nanotubular TiO(2) arrays surface is synthesized by electrochemical anodization with wet chemical pretreatment; it shows almost three times higher activity as compared to that of nanotubular TiO(2) arrays alone.

A continuous process for the preparation of structurally well-defined uniform alumina (Al2O3) nanotubes was developed. The present nanofabrication approach is based on pulse anodization of aluminum by using sulfuric acid and provides unique opportunity for a facile tailoring of the length of nanotubes by controlling the pulse duration.

In the presented work the dynamic simulation of a silicon anodization process is performed. Two mechanisms of etch form development (diffusion in electrolyte, current flow) are considered and simulated. Influence of electrolyte conductivity and radius of the opening in the masking layer is discussed.

Nb-doped TiO(2) nanotube (with C(Nb) < 1 wt%) layers were successfully fabricated by self-ordered electrochemical anodization of Ti-Nb alloys. When used in dye-sensitized solar cells the efficiency enhanced by up to 30% compared to non-doped TiO(2) nanotubes. IMVS measurements indicate the beneficial effect to be due to lower recombination losses.

The highly ordered titanium dioxide nanotube coatings were produced under various electrochemical conditions on the surface of titanium foil. The anodization voltage changes proved to be a main factor which directly affects the nanotube morphology, structure, and wettability. Moreover we have noticed a significant dependence between the size and crystallinity of TiO2 layers and the adhesion/pro...
