We report on the development of a simple and efficient method to predict the structural transition and the bulk-to-nano transformation of spherical FCC and BCC solid nanoparticles using the surface atomic packing fraction (). For both structures, 's are maxima at radii equal to the nearest neig...
a. The bcc lattice has a packing fraction of 0.68. b. The fcc and hcp lattices have a packing fraction of 0.74. Packing Fraction: A unit cell contains several atoms depending on the crystalline struct...
The packing fraction of the crystal lattice can be determined by finding the volume of the atoms (spheres) and the volume of the cube. For this, we must known the number of the atoms present in the crystal lattice.An...
Results: Both, A-RTS and SEM, show that with the vertical convective self-assembly method, with the appropriate parameters of temperature of evaporation (60°C), volume fraction of the colloidal suspension (0.2% w/w) and acidity (pH=6), highly orderedclose packedface centeredcubic(fcc) SiO2...
