[Single cell gel electrophoresis of a magnesium alloy coated with beta-tricalcium phosphate].

Objective: To evaluate the genotoxicity of a magnesium alloy coated with beta-tricalcium phosphate (beta-TCP).

Methods: Four groups were designed. In the first group, AZ31B magnesium alloy surface was coated with beta-TCP using chemical bath deposition, and in the second group magnesium alloy was tested.

[Weibull analysis and flexural strength of glass-infiltrated alumina composite machined by CAD/CAM].

Purpose: To explore the structural reliability of machined infiltrated ceramic made from ultrafine alumina powder for dental CAD/CAM by means of flexural strength together with Weibull analysis.

Methods: Ultrafine grain-sized alumina powder made from ammonium aluminum sulfate was sintered into one kind of porous machined ceramic block. After being infiltrated by lanthanum glass powder, a glass infiltrated alumina composite was produced.
