“…To graft FT NPs onto the AC surface, 0.1 g of functionalized AC and 0.4 g of FT NPs were dispersed and mixed in 100 mL of distilled water under stirring at room temperature for 30 min according to the method described by Ashkarran et al. 24. The prepared FT/AC composite was dried at 100 °C and calcined at 300 °C for 1 h.…”

Fe2O3/TiO2/activated carbon (FT/AC) nanocomposites supported on silica gel beads were synthesized using a sonochemical method and fully characterized. The response surface method was applied to optimize the removal of Pb(II) ions by nanocomposites under visible light. The experiments were conducted by adjusting three parameters, i.e., initial concentration of Pb(II) ions, dosage of Fe2O3/TiO2 (FT) photocatalyst, and pH. The FT/AC nanocomposite showed higher efficiency for Pb(II) ion removal in comparison with FT due to the synergistic effect of activated carbon combined with Fe2O3/TiO2.

“…According to Ashkarran et al, they have prepared CNT-TiO2 using three different simple mixing methods: (i) simple mixing of CNTs with TiO2 nanoparticles, (ii) simple mixing of CNTs with TiO2 nanoparticles followed by heat treatment and (iii) simple mixing of CNTs with TiO2 nanoparticles followed by UV illumination. From the TEM image, they have found that TiO2 nanoparticles are well decorated on the CNTs surface in all three simple mixing methods [36].…”

The shortage of worldwide clean water and the increasing water demand are now ubiquitous problems around the world. Thus, efficient water treatment is an important research topic, of which phocatalysis is known as simplest and efficient technique utilized in the photocatalytic degradation of all major water pollutants, including heavy metal ion, organic and inorganic pollutants. In this context, the use of one- dimensional carbon nanotubes-based nanocomposites in water treatment have been widely demonstrated to be capable of removing persistent organic compounds due to their unique physical and electronic properties, large surface area, tunable morphology, biocompatible and chemical-environmental-thermal stability. This chapter begins with the discussion of the importance and properties of carbon nanotubes, and then briefs about the types and methods of preparation of carbon nanotubes-based nanocomposites in detail. The next section emphasizes the fundamentals of photocatalysis phenomenon and its proposed mechanism for the photocatalytic degradation of pollutants. The last section highlights the recent development in the carbon-based nanocomposites as photocatalyst in water treatment systems, supported by comprehensive literature account. Finally, the remaining challenges and perspectives for using carbon nanotubes-based nanocomposites are discussed.

“…Nanostructured TiO 2 has a positive effect on the performance of bone cells. TiO 2 is available in the form of nanocrystals [ 535 ], nanofibers [ 536 ], nanoparticles [ 537 ], also immobilized on nanotubes [ 538 ]. TiO 2 nanotube coating on any substrate enhances hydroxyapatite formation in SBF [ 539 ].…”

One of the most important ideas ever produced by the application of materials science to the medical field is the notion of biomaterials. The nanostructured biomaterials play a crucial role in the development of new treatment strategies including not only the replacement of tissues and organs, but also repair and regeneration. They are designed to interact with damaged or injured tissues to induce regeneration, or as a forest for the production of laboratory tissues, so they must be micro-environmentally sensitive. The existing materials have many limitations, including impaired cell attachment, proliferation, and toxicity. Nanotechnology may open new avenues to bone tissue engineering by forming new assemblies similar in size and shape to the existing hierarchical bone structure. Organic and inorganic nanobiomaterials are increasingly used for bone tissue engineering applications because they may allow to overcome some of the current restrictions entailed by bone regeneration methods. This review covers the applications of different organic and inorganic nanobiomaterials in the field of hard tissue engineering.
