introduction: the aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. methods: three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. results: larger nodules and poros...

Abstract Chitin has proven to have a good mechanical and electrical properties be used in making piezoelectric thin films. However, due the restriction solubilizing chitosan many solvents, there is increasing interest exploring of producing Chitosan, compared chitin, can easily solubilized certain dilute acids. Chitosan that been extracted from fungal biomass for fabrication biomaterial There a...

The bioadhesive buccal film drug delivery technology that increases the safety, effectiveness, and stability of active pharmaceutical ingredients is main focus current article. cutting-edge since it offers a better way to maximise treatment effectiveness. medications are used increase bioavailability have high first-pass metabolism ideal for this strategy. Rolling, hot-melt extrusion, solid dis...

This study was aimed at assessing the potential use of electrospun fibers as drug delivery vehicles with focus on the different diameters and drug contents to control drug release and polymer fiber degradation. A drug-loaded solvent-casting polymer film was made with an average thickness of 100 microm for comparative purposes. DSC analysis indicated that electrospun fibers had a lower T(g) but ...

This work demonstrated the importance of pre-formulation studies and proposed a generalised scheme for excipient screening in early stage amorphous solid dispersion(ASD) system development by profiling excipients’ capability to solubilise, amorphisise, stabilise chosen active pharmaceutical ingredient (API) an effort rank their suitability. Lumefantrine, antimalarial compound with both poor sol...

Hot-melt pressure-sensitive adhesive (HMPSA) is an environmentally benign which typically processed without solvent in industries. However, casting solution method commonly used for experimental purposes the lab convenience. Therefore, seven types of with different polarities, including toluene as most solvent, were investigated this work to study feasibilities. Quick bond strength and holding ...

practical applications of conducting polymers such as polyaniline as membranes are particulary limitedbecause of their poor mechanical properties. however by mixing polyaniline with some conventional insulatingpolymers such as nylon and preparation composite films through solvent casting or blending, it seems to be asuitable way in order to increase the mechanical properties of the conducting p...
