The objective of this work was to examine osteoblast-like cell attachment and morphology in vitro to osteoceramic materials with three different surface morphologies. Osteoceramic composite disks were fabricated from tricalcium phosphate and magnesium-aluminate spinel (MgAl2O4) in a 50 vol% ratio....

A new class of gold nanostructures has been fabricated on the (100), (111), and (110) surfaces of lattice-matched MgAl(2)O(4) substrates. The nanostructures were fabricated through a synthesis route where a thin gold film dewets, liquefies, and then slowly self-assembles. The...
