For load-bearing or bone-contacting applications, including renovation of congenital skeletal abnormalities, joint and tooth replacement, and fracture healing, metallic implants have gained extensive use and acceptance. Cathodic electrodeposition from zinc sulfate-based electrolytes containing gelatin was carried out to prepare composite coatings of zinc and nano-sized yttriastabilized zirconia (YSZ) particles. Through immersion in simulated body fluid and cell proliferation performed separately several times, the apatite precipitation of the YSZ-coated Ti was studied to measure its biocompatibility and bioactivity. It can be seen that the developed YSZ-Ti showed decreased inflammatory response compared to bare Ti implants due to its excellent tissue attachment features, apatite formation capacity, and biocompatibility.

A sub-micron spherical powder material-micro bead, which has good water reduction, filling and enhancement effect, could be used as active mineral admixture in high-strength concrete. The affection of micro bead on the hydration temperature rise, mechanical properties, and shrinkage properties of high-strength concrete were studied, and the results showed that: micro bead could reduce the highest temperature peak of concrete, and at the low water-cement ratio, its small dosage could develop the compressive strength of concrete, and after instead of silica fume with suitable dosage, it could reduce the shrinkage of high-strength concrete.
