Facial trauma, bone resection due to cancer, periodontal diseases, and bone atrophy following tooth extraction often leads to alveolar bone defects that require bone regeneration in order to restore dental function. Guided bone regeneration using synthetic biomaterials has been suggested as an alternative approach to autologous bone grafts. The eff...
A stepped-plate transducer (SPT) uses an extensive radiating plate to produce highly-directional ultrasound beams. In this paper, we present an improved analytical model for designing the polymer-composite stepped-plate transducer (PCSPT). The polymer-composite features the lightweight and flexible properties, and there can be little change in the ...
In order to improve the oxidation resistance of SiC in its ceramic matrix composites (CMCs), monolithic SiC ceramics doped with various proportions of TaB2 were prepared, isothermal and non-isothermal oxidation was investigated in detail as well. It was found that even a small proportion addition of TaB2 can effectively alleviate the intense oxidat...

Preparation of high-entropy carbides in bulk quantities and in powder form via simple methods at relatively low temperature is challenging. Here, we report the first synthesis of (ZrTiTaNbMo)C high-entropy carbide (HEC) powders via magnesiothermic reduction process. In this, a mixture of individual metallic oxides, graphite and magnesium is treated...

Si2N2O ceramic, an emerging functional and structural material, has a wide range of applications. However, the preparation of pure-phase Si2N2O powder remains challenging due to the mass transfer resistance and unde-sirable side reactions in the conventional methods. Herein, a novel molecular approach combined with the decomposition process has bee...
