“…Furthermore, highly porous Ti–Co alloys are recently being developed for biomedical applications [ 198 ]. Two methods are proposed for the combination of cobalt (II, III) oxides with TiO2 NTs; (i) the anodization of Ti foils to create TiO2 NTs followed by the deposition of cobalt (II, III) oxides via different approaches, and (ii) melting the Co and Ti into alloys and the formation of the MONs by electrochemical anodization [ 199 , 200 ]. In the first method, the cobalt (II, III) oxides were deposited onto the surface of TiO2, leading to agglomeration, shedding, and dissolution of the cobalt (II, III) oxides.…”

Nanomedicine has seen a significant rise in the development of new research tools and clinically functional devices. In this regard, significant advances and new commercial applications are expected in the pharmaceutical and orthopedic industries. For advanced orthopedic implant technologies, appropriate nanoscale surface modifications are highly effective strategies and are widely studied in the literature for improving implant performance. It is well-established that implants with nanotubular surfaces show a drastic improvement in new bone creation and gene expression compared to implants without nanotopography. Nevertheless, the scientific and clinical understanding of mixed oxide nanotubes (MONs) and their potential applications, especially in biomedical applications are still in the early stages of development. This review aims to establish a credible platform for the current and future roles of MONs in nanomedicine, particularly in advanced orthopedic implants. We first introduce the concept of MONs and then discuss the preparation strategies. This is followed by a review of the recent advancement of MONs in biomedical applications, including mineralization abilities, biocompatibility, antibacterial activity, cell culture, and animal testing, as well as clinical possibilities. To conclude, we propose that the combination of nanotubular surface modification with incorporating sensor allows clinicians to precisely record patient data as a critical contributor to evidence-based medicine.

“…The presence of oxygen vacancies has been ascribed to play a significant influence on the magnetic properties of several DMO [4,10,13]. For that reason, much recently, research of ZrO 2 -based DMOs has focused on the study of nanostructures [16,17,18,19,20,21] with large surface/volume ratio and thus a proper environment for oxygen vacancies.…”

We synthesized pure and Co-doped (6.25 -12.5% at.) ZrO 2 nanopowders in order to study their magnetic properties. We analyzed magnetic behavior as a function of the amount of Co and the oxygenation of the samples, which was controlled by low pressure thermal treatments. As prepared pure and Co-doped samples are diamagnetic and paramagnetic respectively. Ferromagnetism can be induced by performing low pressure thermal treatments to the samples, which becomes stronger as the dwell time of the thermal treatment is increased. This behavior can be reversed, recovering the initial diamagnetic or paramagnetic behavior, by performing re oxidizing thermal treatments. Also, a cumulative increase can be observed in the saturation of the Magnetization with the number of low pressure thermal treatments performed to the sample. We believe that this phenomenon indicates that cobalt segregation induced by the thermal treatments is the responsible for the magnetic properties of the ZrO 2 -Co system.

“…Effective degradation of these pollutants requires advanced oxidation processes (AOPs), which are based on the production of oxidizing radicals. [1][2][3][4][5] Among the various AOPs, photocatalysis has been studied extensively by several researchers to enhance the photocatalysis activity by modication of catalysts with transition metals (Fe-, Au-, Ag-, Mg-, Ni-, Au-) 6,7,[8][9][10][11][12][13] and rare-earth elements (Ce-, Er-, Yb-) 14,15 as well as non-metallic elements (N-and F-) 16,17 and 2D layered materials (such as graphene, MoS 2 etc.). 18 The more recent AOP of sonolysis has been used for degradation of wide variety of recalcitrant pollutants.…”

2In this paper, we have reported sonochemical synthesis and characterization of zirconium 3 ferrite (ZrFe 2 O 5 ), and its use as catalyst in advanced oxidation processes (AOPs) using 4 decolorization/ degradation of azo and non-azo dyes as model process. The efficacy of 5 ZrFe 2 O 5 for dye decolorization has been compared with the conventional catalyst TiO 2 6 synthesized using sonochemical sol-gel method. Sonochemically synthesized ZrFe 2 O 5 and 7TiO 2 have been characterized using PSD, XRD, FESEM, TEM, DRS, BET and TGA. ZrFe 2 O 5 8 is revealed to have lower band gap energy than TiO 2 . However, 2 3
