“…Given the goal of conferring biocide or biocolonisation prevention properties to the final product and the aforementioned biocompatibility of PDMS, it was necessary to introduce a third precursor in the formulation. Based on the antimicrobial properties of zirconium [ 28 , 29 , 30 ] and the group’s previous experience with Zr in PDMS–TEOS prepared by γ-irradiation, TPOZ was the choice of Zr precursor to be used.…”

Electron Beam Irradiation on the Production of a Si- and Zr-Based Hybrid Material: A Study by FTIR and WDXRF

Sol-gel production of hybrid materials has, to some extent, revolutionised materials’ engineering and the way science and technology perceive the creation of new materials. Despite that, the method presents some limitations that are circumvented by radiation processing. Electron beam irradiation was used to promote synthesis of hybrid structures while using silanol-terminated PDMS, TEOS and TPOZ as precursors. Evaluation of the method’s performance was executed by gel fraction determination, WDXRF and FTIR-ATR. Results showed that, although there is some pre-irradiation reactivity between precursors, radiolysis induces scission on multiple sites of precursor’s structures, which induces hybrid network formation to a greater extent. Characterisation allowed determining electron beam irradiation to be effective in the creation of Si–O–Zr bonds, resulting in the production of a Class II hybrid material.

Biomedical applications of zirconia nanomaterials were limited in biological systems. In this research, 8–15 nm size zirconia nanoflakes (ZrNFs) were fabricated and their nature, morphology, and biocompatibility were evaluated. The synthesis was carried out using Enicostemma littorale plant extract as an effective reducing and capping agent. Physiochemical properties of prepared ZrNFs were characterized using diverse instrumental studies such as UV‐vis spectrophotometer, Fourier‐transform infrared, powder X‐ray diffractometer, scanning electron microscope, transmission electron microscope (TEM), energy dispersive X‐ray, and cyclic voltammetry (CV). The XRD pattern confirmed the tetragonal phases of ZrNFs and the highest crystallite size of Zr0.02, Zr0.02, and Zr0.06 was 56, 50, and 44 nm, respectively. The morphology of samples was assessed using TEM. Electrophysiological effects of ZrNFs in the cellular interaction process were revealed by the slower rate of electron transfer results in CV demonstration. Biocompatibility of synthesized ZrNFs was studied on A431 human epidermoid carcinoma epithelial cells. The cell viability was increased with an increasing the concentration of nanoflakes up to 6.50–100 μg/mL. The cell viability and observed IC50 values (44.25, 36.49, and 39.62 μg/mL) reveals that the synthesized ZrNFs using E. littorale extract is found to be efficient toxic to A431 cancer cell lines.

The synthesis of yttria‐stabilized zirconia nanoparticles with a fine control on the chemical composition and the distribution of yttrium cations is of major interest to master the mechanical, optical or ionic conduction properties of the final material. However, a fine control of this chemical homogeneity within the particles, especially above 5 mol.% of yttria (Y2O3), is challenging with conventional synthesis routes. In the present study, for the first time the interest of using supercritical sol–gel like synthesis is demonstrated for the continuous production in a single step of high quality zirconia (ZrO2) nanocrystals of 7 nm stabilized with Y2O3 without post‐treatment. Three compositions are investigated, i.e., 1.5, 3, and 8 mol.% of Y2O3 and in‐depth physico‐ chemical characterizations such as X‐ray diffraction, total X‐ray scattering, High‐resolution electron microscopy, Raman and X‐ray photoelectron spectroscopy are performed to asses and thus prove the successful synthesis of these different compositions while keeping a good chemical homogeneity. This enables to confirm that this original process leads to a unique and fine structural control for such small yttria‐doped zirconia nanocrystals.
