microencapsulation has become a common technique in the production of controlled release dosage forms. many results have been reported, concerning the use of alginate beads as controlled release drug formulations. alginate has a unique gel-forming property in the presence of multivalent cations, in an aqueous medium. ibuprofen is an excellent analgesic and antipyretic, non-steroidal anti-inflam...

Graphene nanomaterials have great potential applications in treating wastewater containing pharmaceutical residues due to their extraordinary physicochemical and adsorption properties. Despite being present minute amounts the aquatic environment, can cause various health environmental risks owing non-biodegradability, bioaccumulative toxicity features. Hence, it is extremely vital control conce...

Chitosan with excellent biodegradable and biocompatible characteristics has received attention as an oral drug delivery vehicle for controlled-release formulations. In this study an enteric-coated capsule containing theophylline-chitosan beads based on 23 factorial designs was prepared as a colon drug delivery system. The theophylline-chitosan gel beads were formulated by adding the drug-contai...

Water shortage has risen severely in recent years, confronting mankind with a worldwide challenge, especially as the accessible water resources are further limited by diverse contamination. The most widespread industrial process for treatment is activated sludge process, which, however, excessive production become an enormous environmental problem worldwide. To overcome this problem, hydrogels ...
