Abstract: This paper reports a novel solid freeform fabrication process, Nanoparticle Additive Manufacturing (NAM), for dispersing nanoparticles into molten matrix for improved mechanical properties. In ...

Abstract: Carbon nanotubes were synthesized in an atmospheric chamber by irradiating a metal-catalyst containing graphite target with a 2 kW continuous wave CO2 laser and capturing the soot in flowing ...

Abstract: Hydroxyapatite, a calcium phosphate ceramic, is chemically similar to bone mineral and one of the few materials able to produce direct-bonding osteogenesis. Nanostructured hydroxyapatite coating ...

Abstract: Surface defects generated by grinding deteriorate the flexural strength of the silicon nitride (Si3N4) ceramic. In this paper, CO2 laser surface processing was applied to eliminate the grinding-induced ...
