Fine particle suspensions of various materials in water were agglomerated with heptane in a modified blender to determine the agglomeration characteristics of the solids. The materials included Upper Freeport coal, oxidized Upper Freeport coal, two batches of Illinois No. 6 coal, graphite, and iron pyrite. The response of these materials to oil agglomeration varied over a wide range and seemed ...

A target of best dissolution improvement of poorly soluble drugs is a necessity for the success of formulation in industry. The present work describes the preparation, optimization, and evaluation of a new spherical agglomeration technique for glimepiride as a model of poorly soluble drugs. It involved the emulsification of a drug solution containing a dispersed carrier that tailors the crystal...

Further agglomeration tests were conducted in a series of tests designed todetermine the effects of various parameters on the size and structure of the agglomeratesformed, the rate of agglomeration, coal recovery, and ash rejection. For this series oftests, finely ground Pittsburgh No. 8 coal has been agglomerated with i-octane in a closedmixing system with a controlled amou...

BACKGROUND/PURPOSE To describe small hyper-reflective spherical bodies in sub-silicone oil-foveal depression (SSO-FD) space using spectral domain optical coherence tomography (SD-OCT) and its effect on visual outcomes in eyes undergoing silicone oil removal (SOR). METHODS This was a prospective interventional comparative study comprising 42 eyes undergoing SOR with clear media. All patients u...

In recent years many experimentalists have reported an anomalously enhanced thermal conductivity in liquid suspensions of nanoparticles. Despite the importance of this effect for heat transfer applications, no agreement has emerged about the mechanism of this phenomenon, or even about the experimentally observed magnitude of the enhancement. To address these issues, this paper presents a combin...

This study characterized and removed ash from waste-derived char to improve the quality of char as fuel. Municipal solid waste (MSW) and automobile shredder residue (ASR) were carbonized at 450 degrees C and at 500 degrees C, respectively, in a rotary kiln with a nitrogen atmosphere for 1h. MSW and ASR char were subjected to sieving and pulverization-sieving to screen incombustibles and the ash...

Previous work has shown that when aqueous dispersions of normal corn starch are jet-cooked under excess steam conditions, the properties of the final product depend on the manner in which the cooked dispersion is cooled. Phase separation of the component molecules of starch alters the final properties, and the extent of phase separation depends on the cooling conditions. Both irregular, amorpho...

In pharmaceutical industries, pellets are multiparticulate dosage form which was formed by the agglomeration of fine powdered excipient and drugs together that leads to the formation of small free flowing spherical or semi spherical particles. This technique is called as pelletization process. Pellets are typically varied between 500-1500 μm in size for pharmaceutical applications. It is of gre...
