Steric stabilization by polymers adsorbed on inorganic particle surfaces is gaining more and more attention in both industry and academia because it plays an important role in stabilizing colloidal dispersions. In this review, basic concepts and some related topics about steric stabilization are introduced. In addition the application of steric stabilization in dispersing ceramic particles in n...

The size-dependent metal to nonmetal transition in metal nanoparticles has been investigated using photoelectron and tunneling spectroscopic techniques. Metal nanoparticles capped by thiols are shown to organize into ordered 2D and 3D structures. Single-walled nanotubes and aligned carbon nanotube bundles have been synthesized by controlling the size of metal nanoparticles produced in situ duri...

The energetic χ-criterion is developed to parameterize difference in the origin of high-order optical non-linearity associated with metallic atoms (Cu, Ag, Au) embedded destructively in oxide- and chalcogenide glasses. Within this approach, it is unambiguously proved that covalent-bonded networks of soft semiconductor chalcogenides exemplified by binary As(Ge)-S(Se) glasses differ essentially f...

SiO(2)-CaO-P(2)O(5) ternary bioactive glass ceramic (BGC) nanoparticles with different compositions were prepared via a three-step sol-gel method. Polyethylene glycol was selected to be used as the surfactant to improve the dispersion of the nanoparticles. The morphology and composition of these BGC nanoparticles were observed by ESEM and EDX. All the BGC particles obtained in this method were ...

Chiral Ceramic Nanoparticles In article number 2206956, Hendrik Heinz, Nicholas A. Kotov, and co-workers describe how the chirality of V2O3 nanoparticles strongly changes when they intercalate Zn2+ ions, generating strong modulation f polarization rotation from ultraviolet to infrared range. High g-factors, synthetic simplicity, environmental robustness self-assembled composite films chiral pro...

automotive and aerospace industries are required to light materials which have high properties. this causes to reduce production cost and fuel consumption. one of these advanced materials that have been attracted at these decades is particulate metal matrix nanocomposites. these materials have a combination of ductile matrix alloy properties and ceramic reinforcement nanoparticles. powder metal...

Barium titanate, BaTiO3, nanoparticles (NPs) have been widely used as a ferroelectric/piezoelectric/ pyroelectric material in the electronic-optical ceramic industry. However, stability of BaTiO3 NP suspension is matter concern for their advanced applications wet-ceramic manufacturing, imaging, and electrorheological fluids. In this study, we investigated effect three different surfactants (sod...
