“…Figure 3b gives the FTIR spectra of the obtained CQDs/TiO 2 particles, which reveal the composition and functional group information of the tested materials. The peak at 565 cm −1 generated by the role of Ti-O in TiO 2 , which confirms the existence of TiO 2 in the CQDs/TiO 2 composites [31,33]. The corresponding peak of 1400 cm -1 is assigned to the C-O bond, and the vibration peak at 1625 cm −1 is ascribed to the unsaturated C = C bond.…”

The design and optimal synthesis of functional nanomaterials can meet the requirements of energy and environmental science. As a typical photocatalyst, TiO2 can be used to degrade dyes into non-toxic substances. In this work, we demonstrated the in-situ hydrothermal synthesis of carbon quantum dots (CQDs)-modified TiO2 (CQDs/TiO2) particles, and the subsequent fabrication of three-dimensional (3D) graphene oxide (GO) foam doped with CQDs/TiO2 via a facile strategy. By making full use of the up-conversion characteristics of CQDs, the synthesized CQDs/TiO2 exhibited high catalytic activity under visible light. In order to recover the photocatalyst conveniently, CQDs/TiO2 and GO were mixed by ultrasound and loaded on 3D polyurethane foam (PUF) by the multiple impregnation method. It was found that GO, CQDs/TiO2, and PUF reveal synergistic effects on the dye adsorption and photocatalytic degradation processes. The fabricated 3D CQDs/TiO2/GO foam system with a stable structure can maintain a high photocatalytic degradation efficiency after using at least five times. It is expected that the fabricated 3D materials will have potential applications in the fields of oil water separation, the removal of oils, and the photothermal desalination of seawater.

“…Several studies have shown that nano TiO 2 could improve bioactivity and mechanical properties [39,40], when coated in a composite-like structure with, for instance bioglass, silk, and other polymers [[11], [12], [13], [14], [15], [16], [17], [18]]. Nevertheless, study on nano TiO 2 coating to other type of biopolymers, also its possibility to induce osteogenesis has yet to be elucidated thoroughly.…”

Highlights Chitosan hybridized with titanium dioxide nanoparticles improves its bone regeneration capability. Nano titanium dioxide addition to the matrix of chitosan sponges was done successfully, as depicted from an even distribution of nano titanium dioxide on the surface of the sponges. Chitosan – nanoTiO 2 scaffold results in significantly improved sponge robustness, biomineralization, and bone regeneration capability, as indicated by DMP1 and OCN gene upregulation in chitosan-50% nanoTiO 2 sample.

“…Tetraethyl Orthosilicate (TEOS), a widely used precursor was also used to synthesize bioactive glass [BG (TEOS)] as mentioned in our earlier reports. 22,23 Other than silica, orthophosphoric acid, calcium nitrate tetrahydrate, and sodium hydroxide were used for phosphorus, calcium, and sodium precursors. The chemicals were procured from Sigma Aldrich, India and used without further purification.…”

The sol‐gel route of synthesizing bioactive glasses of composition 45S5 has shown higher compatibility than the melt casting method. In bioactive glass synthesis, a major silica source is derived from the synthetic tetraethyl orthosilicate precursor. This work demonstrates the sol–gel‐derived bioactive glass prepared from rice husk and TEOS as silica sources. In this study, the effect of crystallization with respect to the silica source in bioactive glass composition was investigated to gain further understanding on the processes involved in the fabrication of bioglass. The in vitro biodegradation and apatite formation of the bioactive glass in simulated body fluid was investigated by spectroscopic and morphological studies. Both the bioactive glasses show a change in morphology toward nanostructured apatite formation after in vitro immersion studies. Further, the hemocompatibility of bioactive glass prepared using rice husk is similar to bioactive glass prepared from organic silica sources. This promises the possibility of synthesizing low cost and biocompatible bioactive glass 45S5 system for tissue engineering applications.
