The Coefficient Of Friction

The friction coefficient of tribology pair between silicon nitride ceramic and stainless steel was researched with bovine serum albumin, saline and water lubricants. The coefficient of friction of silicon nitride in bovine serum albumin is lower than those in saline and water. Using digital microscope, the worn surfaces of silicon nitride and stainless steel were viewed. The groove depths of worn stainless steel surface were measured. The depth with bovine serum albumin is shallower than those in saline and water. The results showed that ceramic in bovine serum albumin has good tribological characteristic. This research provides the reference for the development of ceramic artificial joint.

D Value

Objective:To evaluate the lethality profile of an infrared radiation (IR) prototype sterilizer.Method:Simulated use and D value tests were conducted with Bacillus subtilis spores American Type Culture Collection–9372. A spore suspension (1.06 ± 0.03 × 106) in 5% bovine serum albumin was air dried on stainless steel instruments. IR cycles were completed and the instruments were immersed in tryptic soy broth for 120 hours at 37°C. Direct enumeration of survivors was performed to evaluate IR death. Instrument loads contained carriers laden with spores (1.06 ± 0.3 × 106). The spores were seeded on tryptic soy agar and survivors were counted after 120 hours of incubation at 37°C.Results:All instruments exposed to IR (n = 50) were culture negative. In contrast, all unprocessed instruments (n = 30) showed B. subtilis growth. The prototype's D value was 0.56, and the death rate's slope was -1.76 (r = -0.99741; P < .0001). The 10-6 sterility assurance level was reached after 8 minutes and 40 seconds of exposure, from cold start.Conclusions:IR destroys B. subtilis spores. Instrument sterilization with IR may provide another technology for infection control.
