“…Sreekantan et al [167] developed TNT using different kinds of CEs such as iron, carbon, stainless steel, and aluminum. They found that the TNT produced using stainless-steel cathode is short and having thin (5-10 nm), non-uniform walls thickness, and their diameter seems to vary non-uniformly at the top and bottom, which results in conical shaped TNT.…”

“…Since sintering is an activated process involving mass transfer process, a higher annealing temperature and/or prolonged annealing process favor more sintering, which led to complete destruction of TNT structures [198]. In other words, the change in the morphology of TNT with annealing temperature could be associated with the excessive Ti ion diffusion along the tube walls, which induces the oxidation, and thus thickens the tube wall thickness [167,199].…”

“…In addition, annealing at higher temperature leads to the formation of barrier layer between the tubes and the underlying Ti substrate [211]. In other words, decrease in the lateral spacing of TNT with annealing temperature could be associated with the excessive Ti ion diffusion along the tube walls, which induces the oxidation, and thus thickens the tube wall thickness, i.e., decreases the lateral spacing [167]. Besides, the distance between the WE and CE also influences the inter-tubular spacing, which was already discussed in the previous section (Sect.…”

“…44,45 Further, remarkably, the self-ordering anodization approach is not only limited to Ti and Ti-based alloys but can also be applied to a large range of other transition metals or alloys to form highly ordered nanoporous or nanotubular oxide layers for potential biomedical applications. [46][47][48][49][50] For these reasons, this review focuses on up-to-date research that describes the synthesis of these nanotubular structures and the factors that influence the degree of self-ordering, tubular geometry, and crystal structure.…”

Due to increased awareness and interest in the biomedical implant field as a result of an aging population, research in the field of implantable devices has grown rapidly in the last few decades. Among the biomedical implants, metallic implant materials have been widely used to replace disordered bony tissues in orthopedic and orthodontic surgeries. The clinical success of implants is closely related to their early osseointegration (ie, the direct structural and functional connection between living bone and the surface of a load-bearing artificial implant), which relies heavily on the surface condition of the implant. Electrochemical techniques for modifying biomedical implants are relatively simple, cost-effective, and appropriate for implants with complex shapes. Recently, metal oxide nanotubular arrays via electrochemical anodization have become an attractive technique to build up on metallic implants to enhance the biocompatibility and bioactivity. This article will thoroughly review the relevance of electrochemical anodization techniques for the modification of metallic implant surfaces in nanoscale, and cover the electrochemical anodization techniques used in the development of the types of nanotubular/nanoporous modification achievable via electrochemical approaches, which hold tremendous potential for bio-implant applications. In vitro and in vivo studies using metallic oxide nanotubes are also presented, revealing the potential of nanotubes in biomedical applications. Finally, an outlook of future growth of research in metallic oxide nanotubular arrays is provided. This article will therefore provide researchers with an in-depth understanding of electrochemical anodization modification and provide guidance regarding the design and tuning of new materials to achieve a desired performance and reliable biocompatibility.

“…A particular, convenient method for the formation of nanotubes is the nano-anodization of Ti [5,6]. The use of TiO 2 nanotubes generated by this approach for photocatalysis applications was demonstrated by several authors [7,8]. Here we report on recent studies of the photocatalytic activity (PCA) of TiO 2 nanotubes grown on Ti bulk material at different electrolytes and compare the data with respect to the standard reference material Pilkington Activ™ [9].…”

TiO 2 is well known as a low-cost, highly active photocatalyst of good environmental compatibility. Recently it was found that TiO 2 nanotubes promise to enable for high photocatalytic activity (PCA). In our experiments, we studied the photocatalytic activity and spectroscopic properties of TiO 2 nanotube arrays formed by the anodization of Ti. The PCA efficiency related to the decomposition of methylene-blue was measured. To obtain reliable data, the results were calibrated by comparing with standard materials like Pilkington Activ™ which is a commercially available self cleaning glass. The studies included a search strategy for finding optimum conditions for the nanotube formation and the investigation of the relationship between PCA and annealing temperature. TiO 2 nanotubes of different shapes and sizes were prepared by an anodization of Ti foil in different electrolytes, at variable applied voltages and concentrations. The photo-dissociation of methylene-blue was detected by UV-VIS spectroscopy. For the optimized material, an enhancement factor of 2 in comparison to the standard reference material was found. Furthermore, femtosecond-laser induced photoluminescence and nonlinear absorption of the material were investigated. Possibilities for a further enhancement of the PCA are discussed.
