STUDIES ON PARTICLE SIZE CONTROL OF GELATION MICROSPHERES

Nanofibrous microspheres via emulsion gelation and carbonization.

Nanofibrous hydrogel microspheres are formed by pH gelation of perylene diimide derivatives in emulsion droplets. These microspheres are freeze-dried and subsequently carbonized to produce discrete N-doped nanofibrous carbon microspheres. The carbon microspheres show high performance as electrode materials for supercapacitors.

Particle Size Effects on Hydro-Cyclone Performance

The hydrocyclone has a very important roll in industrial separation. The consideration of its behavior is very important for design. In this investigation, behavior of water flow and particles trajectory inside a hydrocyclone has been considered by means of numerical and experimental methods, and results have been compared together. To have a numerical simulation, a CFD software was used, and f...

Preparation of Microspheres of Diclofenac Sodium by Ionotropic Gelation Technique

Diclofenac sodium is a non-steroidal anti-inflammatory drug used in the treatment of arthritis. Treatment with NSAIDs is observed to have gastro intestinal side effects and the formulation of Diclofenac sodium using biodegradable and biocompatible polymer in the form of microspheres is expected to decrease GI side effects. In the present study, different microsphere formulations of Diclofenac S...

Formulation and evaluation of captropril microspheres by ionic gelation technique

The development of oral sustained or controlled release dosage form of captopril has been an interested topic of research for a long period of time. Difficulties encountered on the fact that the drug is freely water soluble. Such drug is difficult to be delivered orally in a sustained or controlled release manner and, Due to its effectiveness and intensive use as a drug of choice in the treatme...
