The purpose of this study was to develop novel nanoscale biosensors using titania nanotubes (TNTs) made by anodization. Titania nanotubes were produced on pure titanium sheets by anodization at room temperature. In this research, the electrolyte composition ethylene glycol 250 mL/NH4F 1.5 g/DI water 20 mL was found to produce the best titania nanotubes array films for application in amperometri...

This paper presents titanium dioxide nanostructured surfaces prepared in organic electrolytes containing ammonium fluoride by anodic oxidation method. Two approaches were used for fabrication, one-step and two-step anodization. The obtained TiO2 surfaces have nanoporous structure. The morphology of anodized TiO2 nanostructures was characterized by scanning electron microscopy (SEM).

In this research, the CoZn alloy nanowire arrays were deposited in a porous aluminum oxide template by alternative current pulse electrodeposition. The was fabricated through two-step soft anodization of pure foils and its morphology determined using scanning electron microscope.In order to systematically study constructed sample, non-destructive ion beam analysis techniques used. Among these m...

A novel template synthesis of bone-shaped (dumbbell-shaped, dogbone-shaped) nanomaterials is demonstrated. Porous anodic alumina (PAA) templates with uniform nanochannels were fabricated using a four-step anodization process and used to form bone-shaped carbon nanostructures with stem and end diameters and lengths of 40 nm, 70 nm, and 5 μm, respectively. These nanomaterials, which we refer to a...

A new dealkylation reaction between organophosphate esters and Salen aluminum bromide compounds has been used to prepare three new aluminum salen compounds salen((t)Bu)AlOP(O)Ph2 (1) (salen = N,N'-ethylenebis(3,5-di-tert-butylsalicylideneimine)), [(MeOH)Alsalen((t)Bu)[OMePO2(O)]Alsalen((t)Bu)[OMePO2(O)]Alsalen((t)Bu)]Br (2), and [salpen((t)Bu)AlO]2[(BuO)2PO]2 (3) (salpen = N,N'-propylenebis(3,5...

introduction: the purpose of the present study was to determine the effect of 17% ethylene,di-amine, tetra-acetic acid (edta), 6% phosphoric acid and erbium: yttrium, aluminum, garnet (er:yag) laser in removing the smear layer by scanning electron microscopy. methods: in this study, 80 single-rooted human teeth were selected. instrumentation was done by use of hand files and step-back technique...
