Spherical agglomeration of aminophylline crystals during reaction in liquid by the spherical crystallization technique.

Comparative Tabletting behavior of Carbamazepine granules with spherical agglomerated crystals prepared by spherical crystallization technique

The aim of this study was to prepare Spherical agglomerates of Carbamazepine by Quesi-Emulsion Solvent Diffusion system (QESDS) with Ethanol-Chloroform-Water system. Granules were prepared by wet granulation method with different excipients.The prepared agglomerates were evaluated for flowability, compressibility, wettability, packability and solubility. Tablets were prepared and evaluated for ...

Liquid Crystals in Spherical Confinement

Ordered systems, such as liquid crystals, are dramatically affected by confinement and curvature. One of the main consequences is the presence of topological defects in the ground state of the liquid crystal. For instance, when a nematic liquid crystal is confined to a thin spherical shell, theory predicts a configuration with four defects arranged in a tetrahedral fashion. This prediction hold...

Spherical agglomeration pdf

Spherical crystallization of drugs.

Spherical crystallization of drugs is the process of obtaining larger particles by agglomeration during crystallization. The most common techniques used to obtain such particles are spherical agglomeration and quasi-emulsion solvent diffusion. Ammonia diffusion systems and crystallo-co-agglomeration are extensions of these techniques. By controlling process parameters during crystallization, su...

Spherical Oil Agglomeration (SOA)/ Colloidal Gas Aphrons (CGA) Flotation

The main aim of this experimental work was to develop a separation process using micro- bubbles less than 100 µm in diameter. Micro-agglomerates were produced using 10kg crude oil/tone feed coal treated compared to 250 kg/tone feed coal treated for conventional spherical oil agglomeration. These micro-agglomerates were separated from the unagglomerated minerals by micro-bubble flotation. Colloi...
