“…XRD analyses were conducted in the 2θ range from 3.03 to 89.91 • with steps of 0.06 • . Narrow peaks identified within the scan range were confirmed using previously published literature [30,31,34,45,46]. …”

“…3b the bands related to Si-O-Si asymmetric and symmetric stretching modes are observed at approximately 1080 and 450 cm −1 , respectively. A typical absorption band observed in silica gel is located at 1640 cm −1 and is attributed to the deformation mode of adsorbed molecular water in the pores [34][35][36][37]. The presence of PVA and other polymers in hybrids significantly reduces the possibility of drying and ageing the systems at temperature above 40 • C. Also, the vibrational band at 950 cm −1 has been credited to the presence of silanol groups (Si-OH) usually found in silica synthesized via sol-gel method.…”

The phosphosilicate for planar waveguides fabrication by using sol-gel, and particularly erbium-doped waveguide amplifiers, is reviewed. In particular, efforts to use sol-gel to improve molecular homogeneity in Er-doped phosphosilicate-based monolith and thin films will be discussed. A variety of material studies was carried out to investigate and optimize the sample preparation condition for such application. These include X-ray diffraction, the Fourier transform infrared and optical transmittance, absorption and refractive index calculation. The erbium nitrate precursors use is shown to alter the Er 3+ ions doping in the prepared samples thermally treated in the final monolith glass form, in comparison to the use of thin film phosphosilicate sol-gel sample. Excess heat treatment is used to force prepared samples crystallization, moreover resulting photoluminescence analysis is used to detect the co-operative-up-conversion sample properties before and after heating.

“…Hong et al [34] used a similar technique to produce 50wt% HA in PCL scaffolds and showed similar cell viability for rat bone marrow stromal cells, but with increased cell differentiation for the HA-PCL scaffolds than the non-reinforced PCL scaffolds. Costa et al [35,36] foamed polyvinyl alcohol (PVA) reinforced with 20 to 40wt% of 58%SiO 2 -33%CaO-9%P 2 O 5 to produce porous scaffolds. After morphological, chemical and mechanicacharacterisation the scaffolds were cultured with cells from the VERO line.…”

One of the major challenges of bone tissue engineering is the production of a suitable scaffold material. In this review the current composite materials options available are considered covering both the methods of both production and assessing the scaffolds. A range of production routes have been investigated ranging from the use of porogens to produce the porosity through to controlled deposition methods. The testing regimes have included mechanical testing of the materials produced through to in vivo testing of the scaffolds. While the ideal scaffold material has not yet been produced, progress is being made.
