“…It indicates that the effect of Al on enhancing thermal stability and controlling crystal growth of anatase TiO 2 cannot be neglected. The improved thermal stability is useful to improve the photocatalytic activity, because the higher level of TiO 2 crystallinity can be obtained by annealing at higher temperatures without forming the rutile structure of low photocatalytic activity 14 .…”

“…Moreover, Varghese reported that the transformation from anatase to rutile was observed at 430 °C 13 . It is significant to improve thermal stability of anatase in order to enhance the photocatalytic activity, because a higher level of crystallinity can be obtained by annealing titania at high temperatures without forming the rutile phase, which is responsible for the low photocatalytic activity of TiO 2 14 . In addition, TiO 2 has some disadvantages such as large band gap and high recombination rate of charge carriers 14 .…”

“…15,27,28,30 Considering that the concurrent observation of bone defects and implantation frequently occurred in clinical practice but lacked experiment evidence, this study attempted to develop a wall of bone-defect model of a Ti implant with a TNT-targeting micelle surface in the middle tibia region of normal and ovariectomized rats to probe the biological effects in vivo. Thus, the bone-targeting Ti implant-bone interface in vivo was constructed.…”

“…The anodizing voltage varied from 0 to 25 V with an increasing rate of 500 mV/s and was maintained at 25 V for 1 h. The prepared TNTs were then annealed in air at 450°C for 4 h to form a steady anatase crystal phase and improve the interfacial structure between the TNT film and Ti substrate. 28,29 The surface morphology of the TNTs was examined by field-emission scanning electron microscopy (SEM; ZEISS ULTRA55; Carl Zeiss Company, Oberkochen, Germany) at an acceleration voltage of 20 kV.…”
