We present the fabrication method for the nonspherical or macroporous particles such as binary colloidal aggregates or shape-anisotropic particles from water-in-oil emulsions as confining geometries for the self-organization. Here, the water droplets contained various combinations of two different colloids: monodisperse silica or polystyrene microspheres for larger particles and silica or titania...
Playing a dual role as a catalyst that destabilizes Fe nanoparticles to form soluble precursors in situ and as a catalytic center for nanorod growth allows Pd nanoparticles to transform Fe nanoparticles and a P source into Fe2P nanorods (see scheme). The diameter and length of the Fe2P nanorods can be fine‐tuned by means of the diameter of the Pd nanoparticles and the Fe/Pd ratio, respectively.
A colloidal dispersion of indium tin oxide (ITO) nanoparticles in an organic solvent was achieved using a milling process in which β-diketones or titanate coupling agents were used as a dispersing agent. Isopropyl tri(N-ethylenediamino)ethyl titanate and 2,4-pentanedione were found to be the most suitable dispersants for stabilizing ITO nanoparticles in a mixed organic solvent. The secondary particle...
