2012/4/1· Introduction Total hip joint replacement is one of the most commonly performed orthopedic operations. 1 A total hip joint replacement has an average life span of about 15 years. 2 Implant failures can be due to several factors but one of the most critical is release of wear particles from the bearing surface of the implant. . Accumulation of wear particles at the implant has been linked to

Effective optimization of surface passivation on porous …

Porous silicon carbide (B–N co-doped SiC) produced by anodic oxidation showed strong photoluminescence (PL) at around 520 nm excited by a 375 nm laser. The porous SiC samples were passivated by atomic layer deposited (ALD) aluminum oxide (Al 2 O 3 ) films, resulting in a significant enhancement of the PL intensity (up to 689%).
