In this paper, an electrospraying technique was applied to prepare polycaprolactone (PCL) polymer particles with a different microstructure. The PCL particles can be controlled to have a porous microstructure by tailoring the evaporation of solvents during the electrospraying process. The effect of various concentrations on the morphology and microstructure of PCL particles was investigated. Th...

Background: Multifunctional core-shell magnetic nanocomposite particles with tunable characteristics have been paid much attention for biomedical applications in recent years. A rational design and suitable preparation method must be employed to be able to exploit attractive properties of magnetic nanocomposite particles. Objectives: Herein, we report on a simple approach for the synthesis of m...

The preparation of size-controlled CdS nanoparticles in block copolymer micelles and formation of composite particles of CdS nanoparticles and polymers are described in this paper. Uniformly sized CdS nanoparticles with different emission wavelengths were successfully synthesized. In addition, composite Janus particles, unidirectionally stacked lamellae particles and onion particles were formed...

Synthesis of BaFe12O19 magnetic nano particles via precipitation in different pH conditions have been reported. The certain molar ratio of Fe/Ba = 12 selected and sodium hydroxide was used as a precipitant agent. X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and vibrating sample magnetometer (VSM) were used to consider the structural, morphological and magnetic properties of bariu...

We investigate the effect of confinement on particle dynamics in mixtures of colloidal particles and non-adsorbing depletant polymers that serve as models for attractive suspensions. Holding the volume fraction of particles and the polymer concentration constant, the dynamics of the particles become increasingly slow as the suspensions are confined in thin wedgeshaped cells. Confocal micrograph...

Multilayered films starting with silica or polymer particles in the micron-size range have been prepared using the Langmuir-Blodgett technique. The polymer particles made of highly cross-linked cores and hydrophilic shells were elaborated through a precipitation polymerization method that allows formation of particles with a low polydispersity. The influence of the surface function, the differe...
