“…Remarkably, the band at 574.7cm -1 similar to that reported by Takase and Tani as originating from Si-N vibrations attributed to α-silicon nitride [12]. The absorption band at 1110.0 cm -1 is attributed to Si-O-Si bonding while the characteristics stretching vibration band of silicon nitride were observed at 669.3 cm -1 [9,11]. The broad peak at 791 cm -1 show an overlap of Si-C in addition to Si-O and Si-N vibration observed at 464.6 cm -1 .…”

“…The absorption band at 470.6 cm -1 is attributed to Si-N (stretching), at this wave-number, there is overlap of Si-O with Si-N, implying amorphous phase [9]. A weak band at 671.2 cm -1 which is characteristic of a silicon nitride Si-N-Si stretching vibrations was observed [11]. The bands at 803.3 cm , due to the overlap, can assume that it may be present in amorphous phase and covered by Si-O bonding [9].…”

Silicon nitride (Si 3 N 4 ) SNA, SNB, SNC and SND were synthesized by hydrothermal process at temperature of 100 Based on their infrared spectra, for SNA absorption band at 470.6 cm-1 is attributed to Si-N (stretching), which were also observed with SNB, SNC and SND, a weak band at 671.2 cm -1 which is characteristic of a silicon nitride Si-N-Si stretching vibration was observed, for SNC, peak at 574 cm -1 attribute to α-silicon nitride, as temperature increases the spectrum becomes sharper. X-ray diffraction pattern indicates that SNA material contained 64.6% α-phase and 27.8% β-phase silicon nitride. Therefore, rice husks and sugarcane bagasse have great potential as a raw material for producing Si 3 N 4 , by the hydrothermal method

“…Si 3 N 4 is a bioinert ceramic that has been reinforced with BG to improve its biocompatibility. In addition to bioactivity improvement, BG aids in the sintering process of Si 3 N 4 . Frajkorová et al combined Si 3 N 4 with sol‐gel derived BG (10 and 30 wt %) by free sintering at 980°C in a nitrogen atmosphere.…”

Bioglass® 45S5 (BG) has an outstanding ability to bond with bones and soft tissues, but its application as a load-bearing scaffold material is restricted due to its inherent brittleness. BG-based composites combine the amazing biological and bioactive characteristics of BG with structural and functional features of other materials. This article reviews the composites of Bioglass in combination with metals, ceramics and polymers for a wide range of potential applications from bone scaffolds to nerve regeneration. Bioglass also possesses angiogenic and antibacterial properties in addition to its very high bioactivity; hence, composite materials developed for these applications are also discussed. BG-based composites with polymer matrices have been developed for a wide variety of soft tissue engineering. This review focuses on the research that suggests the suitability of BG-based composites as a scaffold material for hard and soft tissues engineering. Composite production techniques have a direct influence on the bioactivity and mechanical behavior of scaffolds. A detailed discussion of the bioactivity, in vitro and in vivo biocompatibility and biodegradation is presented as a function of materials and its processing techniques. Finally, an outlook for future research is also proposed. © 2017 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 105A: 3197-3223, 2017.

“…Os biomateriais vêm ganhando espaço na produção dos scaffolds (BARUD et al, 2015;FRAJKOROVA et al, 2015;MARTEL-ESTRADA et al, 2015;NGADIMAN et al, 2015). Ao longo das duas últimas décadas, um meticuloso trabalho foi realizado para explorar biomateriais e superfícies para a engenharia de tecidos (BURG , PORTER e KELLAM, 2000;PARK et al, 2015;SUH e MATTHEW, 2000a).…”
