“…11 FA glass-ceramics have been commercially available for use as inter-vertebral spacers and ossicles of the middle ear since the early 1990s. 12 FA has been used as a coating on metallic implants and direct bone apposition was observed at the interface between the FA coating and bone. 13 It has been found that the crystallinity and microstructure of the FA coating could be more easily modied compared to a HA coating.…”

The development of a bioactive nanocomposite for bone replacement has gained much interest in the field of bone grafting. In this study, a nano fluorapatite (n-FA)-poly(butylene succinate) (PBS) bioactive composite was fabricated using a co-solution method. The results showed that the n-FA-PBS composite had improved hydrophilicity, compressive strength and an elastic modulus, which were obviously higher than those of PBS alone. In addition, the n-FA-PBS composite could inhibit bacterial attachment, with the number of viable bacteria on the composite obviously lower than on pure PBS, indicating good antibacterial ability. Moreover, the attachment and proliferation of human mesenchymal stem cells (hMSCs) on the n-FA-PBS composite was significantly higher than on PBS, and the alkaline phosphatase (ALP) activity of hMSCs on the composite was expressed at significantly higher levels compared to PBS. Furthermore, the hMSCs showed intimate contact with the composite surface and the cells spread and grew significantly better on the composite compared to PBS. Therefore, incorporation of n-FA into PBS is a good way to prepare an inorganic-organic bioactive composite of a nano ceramic and a polymer, which supports cell attachment, proliferation and differentiation. The implantation of the n-FA-PBS composite into the femoral bone of rabbits confirmed that the new bone tissue could form on the composite surfaces, and the composite combined directly with the natural bone tissue without fibrous capsule tissue, showing good osteoconductivity. In short, the n-FA-PBS bioactive composite has good biocompatibility and bioactivity, and has potential application in bone regeneration.

“…The results are consistent with investigations performed on oxynitride glass. [19][20][21][22][23] These studies reveal that the replacement of oxygen with nitrogen improves physical properties such as fracture toughness, microhardness, refractoriness, and chemical durability.…”

“…However, further increases in the heat-treatment temperature to over 1550 C led to a sharp decrease in the mechanical strength of the uorescent oxynitride glass. [19][20][21][22][23][24] In this study, novel exible SiO 2 -based uorescent nanobelt membranes (FNMs) were fabricated via electro-spinning combined with gas-reduction nitridation. The current ndings strongly indicate the great potential of the engineered uorescent inorganic membranes as uorescent materials in exible display technologies and the remote packaging of LED.…”

On the Use of Infrared Thermography and Acousto—Ultrasonics NDT Techniques for Ceramic-Coated Sandwich Structures

et al. 2019

Ceramic-coated materials used in different engineering sectors are the focus of world-wide interest and have generated a need for inspection techniques that detect very small structural anomalies. Non-destructive testing is increasingly being used to evaluate coating thickness and to test for coating flaws. The main pros of non-destructive testing is that the tested object remains intact and available for continued use afterward. This paper reports on an integrated, non-destructive testing approach that combines infrared thermography and acousto-ultrasonics to evaluate advanced aerospace sandwich structure materials with the aim of exploring any potential for detecting defects of more than one type. Combined, these two techniques successfully detected fabrication defects, including inclusions and material loss.
