The use of magnetite nanoparticles for implant-assisted magnetic drug targeting in thrombolytic therapy.
Henrik Kempe,Maria Kempe +1 more
TL;DR: In vitro evaluation in a flow-through model proved that the nanoparticles were captured efficiently to the surface of a ferromagnetic coiled wire at the fluid velocities typical for human arteries.

Organic/Inorganic Composite Latexes: The Marriage of Emulsion Polymerization and Inorganic Chemistry
TL;DR: A review article describes recent advances in the synthesis and properties of waterborne organic/inorganic colloids elaborated through conventional emulsion polymerization, a well-established technology as discussed by the authors, which can be defined as aqueous suspensions of composite latex particles made up of organic and inorganic domains organized into well defined core-shell, multinuclear, raspberry-like, multipod-like or armored morphologies.

Characteristics of flocculated silica dispersions
M Chen,William B. Russel +1 more
TL;DR: In this article, the effect of particle interactions in a flocculated dispersion by measuring the elasticity mechanically and determining the network dimensionality by static light scattering has been investigated, showing that the dispersion changes from fluid to solid within a narrow temperature range, defining a gel transition boundary.

Silica-Protection-Assisted Encapsulation of Cu2O Nanocubes into a Metal–Organic Framework (ZIF-8) To Provide a Composite Catalyst
Bo Li,Jian-Gong Ma,Peng Cheng +2 more
TL;DR: In this article, a template protection-sacrifice (TPS) method was used to encapsulate metastable NPs such as Cu2 O into metal-organic frameworks (MOFs) to form composite materials.
Journal ArticleDOI
Effect of interparticle interactions on size determination of zirconia and silica based systems - A comparison of SAXS, DLS, BET, XRD and TEM.
TL;DR: The size of amorphous SiO2 nanoparticles coincides for different test methods for different measurement methods, and the use of complementary methods is favourable.

Electron Microscopy of Monodisperse Latexes
E. B. Bradford,J. W. Vanderhoff +1 more
TL;DR: In this article, a series of monodisperse polystyrene latexes has been prepared by carefully controlled emulsion polymerizations. The particle diameters of three of these latexes were determined by electron microscopy.
