Polyvinyl chloride (PVC) is one of the popular materials that extensively used in different areas, so scientists are trying to investigate its characteristics formats, such as blends and composites, improve properties. Due distinctive nano particles’ properties, polymer-based nanocomposites can offer new pure polymers widen their applications areas. In this study, we added compositions silicon ...

Electrical cable sheaths are the most abundant fire load in nuclear power plants, mainly rooms that kept under slight pressure. This configuration leads fires to grow under-ventilated and vitiated conditions. Assessing threat involves characterizing heat released, responsible for growth, smoke evolved, which may interact with sensitive components area. For purpose, a revisited controlled-atmosp...

the polysulfone-based membrane has been used in hemodialysis (hd) and it is continuously developed to maintain its sustainability on the subject of biocompatibility. during the polysulfone-based membrane development, several parameters should be considered to improve the membrane performances, such as excellent biocompatibility, appropriate ultrafiltration rate, and effective clearance of the t...

The classical penetration theory was corrected and then applied for the semi-theoretical prediction of mass transfer coefficients kLa in a slurry bubble column operated in the homogeneous regime. The gas-liquid contact time was expressed as a ratio of bubble surface to the rate of surface formation. These terms were defined for the case of oblate ellipsoidal bubbles formed under homogeneous flo...
