Synthesis of hollow NiCo2O4 nanospheres with large specific surface area for asymmetric supercapacitors
TL;DR: Electrochemical measurements show that hollow NiCo2O4 nanosphere electrode is a promising electrode material for the future application in high performance supercapacitors.

Functional assessment of metal oxide nanoparticle toxicity in immune cells.
TL;DR: The varying immune cell response following exposure to nonporous SiO(2) andNonporous TiO( 2) indicates that the nanoparticle-cell interactions are also modulated by surface chemistry.

A NMR technique for the analysis of pore structure: Application to materials with well-defined pore structure
TL;DR: In this article, the authors used NMR spin-lattice relaxation measurements of water contained in porous solids for the determination of pore size distributions, based on the two-fraction, fast-exchange model.

Effects of heat treatment on the aggregation and charging of Stöber-type silica.
TL;DR: This study reports a very different behaviour for Stöber-type silica heated at 800 degrees C, as these particles follow DLVO theory quantitatively, and suspects that the suspension stability of the unheated particles is influenced by the presence of a hairy-layer of polysilicilic acid chains on the surface.

Emerging Techniques for Submicrometer Particle Sizing Applied to Stöber Silica
TL;DR: A comparative study of emerging and established techniques to size submicrometer and nanometer sized particles, evaluating their sizing precision and relative resolution, and demonstrating the variety of physical principles upon which they are based is presented.
