Brief Note: Particle Size as a Factor in Thromboplastin Formation

MULLITE SYNTHESIS AND FORMATION FROM KYANITE CONCENTRATES IN DIFFERENT CONDITIONS OF HEAT TREATMENT AND PARTICLE SIZE

The process of mullitization of kyanite concentrate was studied at different conditions of heat treatment (1400– 1600 °C and 0.5 – 3.5 hours) and particle size of raw materials (38-300 ?m). Kyanite concentrate was obtained fromore-dressing of kyanite deposits of Mishidowan-Bafgh region at 100 km northeastern part of Yazd. The results ofmicrostructure (shape, distribution and size of the grains)...

PARTICLE SIZE CHARACTERIZATION OF NANOPARTICLES – A PRACTICALAPPROACH

Abstract: Most properties of nanoparticles are size-dependent. In fact, the novel properties of nanoaprticles do not prevail until the size has been reduced to the nanometer scale. The particle size and size distribution of alumina nanoparticle, as a critical properties, have been determined by transmission electron microscopy (TEM), photon correlation spectroscopy (PCS), surface area analysis ...

Investigating the effects of particle size and dosage of talc nanoparticles as a novel solid collector in quartz flotation

In this study, hydrophobic talc nanoparticles were applied as a novel class of solid flotation collector. The aim of this work was to understand the effect of talc nanoparticles size and dosage on the quartz flotation recovery. X-ray analysis, dynamic light scattering, and scanning electron microscopy were conducted. Flotation tests were performed in modified a Hallimond flotation cell. The Zet...

Fukushima symposium: a brief note.

Particle-size effects in the formation of bicontinuous Pickering emulsions.

We demonstrate that the formation of bicontinuous emulsions stabilized by interfacial particles (bijels) is more robust when nanoparticles rather than microparticles are used. Emulsification via spinodal demixing in the presence of nearly neutrally wetting particles is induced by rapid heating. Using confocal microscopy, we show that nanospheres allow successful bijel formation at heating rates...
