In this paper synthesis and characterization of a bioactive calcium phosphate glass-ceramic is presented, synthesized using a facile method. The glass-ceramic samples are synthesized with heat treating the parent glass at appropriate temperatures, where different calcium phosphate crystalline phases are grown in the parent glass samples during the heat treatment. The amounts of elements a...
In preceding papers (3, 4, 5) I have discussed various aspects of the problem of the ascent of sap, of how water goes up a tree, and I wish in this paper to carry the discussion forward another step. First, however, I wish to express certain convictions, the fruits of observation, experiment: and reflection, under climatic conditions of considerable variety. I. If one conceive the living body -...
Objective(s): The aim of this study was to synthesis new dental nanocomposites reinforced with fabricated glass nanoparticles and compare two methods for fabrication and investigate the effect of this filler on mechanical properties. Materials and Methods: The glass nanoparticles were produced by wet milling process. The particle size and shape was achieved using PSA and SEM. Glass nanoparticle...
