Progress in developing spray-drying methods for the production of controlled morphology particles: From the nanometer to submicrometer size ranges
TL;DR: In this paper, an aerosol-assisted self-assembly technique, with a spray-drying method as a representative of it, is thoroughly reviewed, and the performance of various particle morphologies is also demonstrated.
Journal ArticleDOI
Preparation of nanoparticles via spray route
Kikuo Okuyama,I. Wuled Lenggoro +1 more
TL;DR: In this article, a simple, rapid and generalizable aerosol decomposition (spray pyrolysis) process for the continuous synthesis of nanoparticles with adjustable sizes, narrow size distribution, high crystallinity and good stoichiometry is described.
Journal ArticleDOI
Correlation between particle size/domain structure and magnetic properties of highly crystalline Fe3O4 nanoparticles
TL;DR: The coercivity of cube-like Fe3O4 NPs increased to a maximum of 190 Oe at the critical size, which suggests strong exchange interactions during spin alignment, and sphere-like NPs have lower magnetic coercivity and remanence values, which is caused by the different orientations of their polycrystalline structure.
Journal ArticleDOI
Synthesis of spherical mesoporous silica nanoparticles with nanometer-size controllable pores and outer diameters
TL;DR: In this article, spherical mesoporous silica particles with tunable pore size and tunable outer particle diameter in the nanometer range were successfully prepared in a water/oil phase using organic templates method.
Journal ArticleDOI
Correlations between Crystallite/Particle Size and Photoluminescence Properties of Submicrometer Phosphors
TL;DR: In this article, the relationship between crystallite/particle size and the luminescent characteristics of submicrometer phosphors was investigated, and the results revealed that the PL properties were strongly dependent on crystallite size, particle size, surface chemistry, and distribution of europium inside the phosphor particles.
