This work reports on the investigation of nanosized CeO2-ZnO systems prepared by Pechini ́s method. The structural and morphological characterization of CeO2-ZnO systems as well as the characterization of CeO2 and ZnO separately, showed that the employed method result in powders with spheroidal particles whose size are in the range 30 200 nm, which is appropriate to provide homogeneous suspensio...

The relationship of the shape and structure of uniform colloidal particles to different mechanisms of formation by precipitation in homogeneous solutions is reviewed. Specifically, conditions leading to (a) amorphous spheres, (b) nonspherical crystals of different shapes, and (c) polycrystalline particles of different morphologies including spheres are distinguished. The last case is observed w...

Magnetotactic bacteria benefit from their ability to form cellular magnetic dipoles by assembling stable single-domain ferromagnetic particles in chains as a means to navigate along Earth's magnetic field lines on their way to favorable habitats. We studied the assembly of nanosized membrane-encapsulated magnetite particles (magnetosomes) by ferromagnetic resonance spectroscopy using Magnetospi...

NiO is a promising electrode material for supercapacitors. Herein, the novel vertically standing nanosized NiO encapsulated in graphene layers (G@NiO) are rationally designed and synthesized as nanosheet arrays. This unique vertical standing structure of G@NiO nanosheet arrays can enlarge the accessible surface area with electrolytes, and has the benefits of short ion diffusion path and good ch...

Poor aqueous solubility of lead drug candidates remains an obstacle for drug development in pharmaceutical industries. Drugs with dissolution rate limited drug absorption show low bioavailability due to poor aqueous solubility of the drug. To overcome these problems different formulations of nanosized drugs were developed recently. Pharmaceutical nanosuspensions consist of dispersed solid drug ...

We propose in this paper a generic model of a nonstandard aggregation mechanism for self-assembly processes of a class of materials involving the mediation of intermediates consisting of a polydisperse population of nanosized particles. The model accounts for a long induction period in the process. The proposed mechanism also gives insight on future experiments aiming at a more comprehensive pi...
