A multiparticulate chitosan-dispersed system (CDS), which is composed of the drug reservoir and the drug release-regulating layer, was developed for drug delivery. The drug release-regulating layer is a mixture of water-insoluble polymer and chitosan powder. The drug is released from CDS pellets in all regions of the gastrointestinal tract (from the stomach to the colon). CDS pellets containing...
The purpose of this study is to develop a novel liquisolid technique to enhance the dissolution rate of poorly water soluble drug Carvedilol, a BCS class II drug, which is a β-blocker, by using different excipients. The main components of a liquisolid system are a non volatile solvent, carrier and coating materials and a disintegrant. Liquisolid system refers to the formulations that are formed...
Deployment of a suspension feedstock has been known to alleviate problems associated with using sub-micron and nanosized powder for thermal spraying monolithic as well powder-suspension ‘hybrid’ composite coatings. However, hybrid never previously used in high-velocity air-fuel (HVAF) spraying. In this work, the very first time, chromium carbide (Cr3C2) co-sprayed along an Inconel-625 (IN-625) ...
The goal of the present study is to prepare a room temperature cured hydrophobic and self-cleaning nano-coating for power line insulators. As a result, the installed insulators operating in power lines can be coated without being removed from the circuit and without the need to cut off power. For this purpose, hydrophobic silica nanoparticles were synthesized by sol-gel method using TEOS and HM...
