The purpose of this study was to characterize a poly(methyl methacrylate) bone cement that was loaded with the antibiotic gentamicin sulphate (GS) and lactose, which served to modulate the release of GS from cement specimens. The release of GS when the cement specimens were immersed in phosphate-buffered saline at 37 degrees Celsius was determined(More)
In the present investigation, the sliding wear behavior is described forAl2O3/ZrO2micro/nanocomposites andmonolithic alumina of similar grain size under defined conditions of a constant sliding speed and different loads (20–150 N). Nano ZrO2 particles (1.7 vol%) were observed uniformly distributing throughout the composites, and most of them were located(More)
Biomorphic silicon carbide stands as a new class of materials fabricated by reactive infiltration of molten silicon in carbonaceous preforms obtained from wood pyrolysis [1]. The basic material is a Si/SiC composite, in which the SiC forms a skeleton that replicates the wood microstructure and the unreacted Si fills the pores. Silicon can be removed from(More)
