The existential state of protein in complexes directly affects the performance and applications of the composite materials. The interlayer space changes of montmorillonite in the protein / montmorillonite (MMT) composite were identified by X-ray diffraction (XRD). And the interaction between protein and MMT were analyzed by Fourier transform infrared spectrometry (FT-IR) and UV/vis spectrophotometry. The loading amount of bovine serum albumin (BSA) onto MMT was calculated from the TG data. The types of adsorption isotherm of BSA onto montmorillonite were analyzed. From the above analysis, it can be concluded that the structure of proteins in the montmorillonite interlayers has been changed, and the hydrogen bond and Van der Waals force between the BSA molecules and montmorillonite crystal layers are intensified. The α-helix content of BSA molecules reduces while random coil increases. The protein shows a state of being squashed.

Good Biocompatibility

As a metallic biomaterial, titanium (Ti) exhibits excellent biocompatibility, but its osteoinductivity is limited. Therefore, to improve this property, an electrophoretic deposition (EPD) technique was used to coat the Ti surface with Ti3C2 MXene (Ti3C2), a new class of two-dimensional nanomaterial. Ti3C2 is known to have good biocompatibility and better osteoinductivity than graphene oxide. The coating layer was characterized by a particulate microstructure and exhibited X-ray diffraction and Raman spectroscopy peaks corresponding to the Ti3C2 phase. In vitro cell tests using human mesenchymal stem cells confirmed that the cell attachment and proliferation on Ti3C2-coated Ti were similar to that of bare Ti, and that the osteoinductivity was significantly enhanced compared with bare Ti.

Glass-ceramics are especially useful for the dental restorations because of their good biocompatibility, chemical stability, aesthetic, mechanical strength and wear resistance. The aim of this work was to obtain one mica glass-ceramic, which can be easily used for rapid machining into all-ceramic tooth with computer assisted design/computer assisted manufacture (CAD/CAM) devices. In the study, on the base of low melting machinable fluorosilicic mica glass ceramics, the effects of CeO2 and Fe2O3 in SiO2-B2O3-K2O-Na2O-Li2O-Al2O3-MgO-F system on color were studied. By orthogonal experimental design, the effects of crystallized parameters on the color, three point flexural strength and machinability of the glass ceramics were obtained, and the samples were analyzed by differential thermal analysis(DTA), X-ray diffraction (XRD) and scanning electron microscopy(SEM), respectively. Experimental results showed that the glass-ceramics with color close to the tooth can be obtained by adjusting the percentage of CeO2 and Fe2O3, and the glass-ceramics crystallized at 680°C for 2h have excellent mechanical properties and machinability.
