“…The transformation of these TNTs to LNTs was done by heating at 600 0 C for one hour. The method of preparing TNPs by rapid break down anodizing (RBA) method is described in detail by (Reem et al, 2020). The Ti foil (0.1 mm thick) with a rectangular form (1 x 2 cm) was submerged in 0.1 M HClO 4 electrolyte after being cleaned with alcohol.…”

“…In current work, there is different titania morphology after heat treatment, as the following paragraphs show. There are numerous studies that demonstrate the bioactivity of titanium oxide (Mustafa et al, 2020;Sang et al, 2007;Chun et al, 2012), but none that demonstrate this activity for lobed nanotubes (LNTs) and deposit TNPs on the LNTs. The purpose of this post is to test the bioactivity of nano titanium oxide in two different forms: LNTs and deposited TNPs on the LNTs.…”

An anodizing method was used to produce TiO2 nanotubes (TNTs) on Ti metal bases. These tubes were transformed into lobed nanotubes (LNTs) by heating at 6000C as scanning electron microscopy (SEM) images showed. A rapid break down anodizing (RBA) technique was utilized to produce TiO2 nanoparticles (TNPs). These particles were deposited on LNTs by the electrophoretic deposition (EPD) method. An X-ray diffraction (XRD) test revealed the polycrystalline composition of the formed LNTs and the amorphous structure of TNPs. The bioactivity of LNTs and the deposited TNPs on the LNTs were tested by immersing them in simulated body fluid (SBF) for one month. For the two samples, XRD patterns showed the appearance of small peaks of hydroxyapatite (HAp), which indicates the bioactivity of these samples. SEM images show that the HAp layer on LNTs was in the form of protrusions, while on TNPs it was in the form of crossed filaments.

“…This method transfers the metal to its oxide with the same element's nanoparticles. Using the RBA approach, nanooxides were created for a variety of applications, including photocatalytic decolorization, sensors, and bioactive materials [8][9][10]. This technique offers a straightforward way to create various nanooxides that are deposited on different bases and have diverse shapes and compositions.…”

The rapid breakdown anodizing method was used to produce (Bi, Bi2O3), (Pb, PbO2), and WO3 nanoparticles. These particles are utilized to fabricate gamma-ray shielding. The X-ray diffraction test displayed polycrystalline structures for all samples. Scanning electron microscope images illustrated the formation of (Bi, Bi2O3) and (Pb, PbO2) nanoplates and WO3 semi-sphere particles. Pressures of 318, 477, and 636 MPa were applied to reduce vacancies within the prepared powders and increase their densities. Cylindrical samples with a diameter of 14 mm and different thicknesses were formed. Utilizing gamma rays produced by sources like Am-241 (59.54 keV), Cs-137 (661.6 keV), Co-60 (1173 keV), and Co-60 (1332 keV), the shielding characteristics of the manufactured samples were studied. The linear attenuation coefficient, mass attenuation coefficient, and half-value layer were determined after the gamma flux was measured using a NaI(Tl) detector. The two attenuation coefficients were functions of the source energy, and they had the highest values for (Pb, PbO2) and the lowest for the WO3 sample. The atomic numbers of the elements used and the size of the voids inside the prepared powders played the greatest role in determining the values of the shielding parameters.

In a single process, the surface of Ti was transformed into titanium oxide nanowires (TNWs) at room temperature. The rapid breakdown anodizing method (RBA) of producing deposited spherical nanoparticles was modified. Instead, TNWs attached to the Ti metal base were formed. To slow down the reactions of these processes, 25,50, and 75wt % glycerol were added separately to the anodizing solution of RBA. The results of the X-ray diffraction (XRD) tests revealed the amorphous structure of the formed TNWs for all samples. The produced TNWs had the shape of micro bundles with nanowires. Their diameters were less than 50 nm, as shown by scanning electron microscope (SEM) images. The prevalence of titania bundles was more intense when a lower amount of glycerol was used. The tallest length of the nanowires decreased from 32μm to 8μm with the increase of glycerol; so by using a suitable electrolyte solution, the anodizing process can be effective for controlling the size of TNWs. The decrease in atomic percent oxygen with increasing glycerol was confirmed by energy dispersion X-ray (EDX) spectra.
