Temperature Sensitivity of Composite Propellants Containing Novel Nano-Additive Catalysts

Studies on the Internal Ballistics of Composite Solid Rocket Propellants Incorporating Nano-Structured Catalysts

This paper deals with the analysis of burn rate using various catalysts of Iron Oxide and determining which gives the higher burn rate with low pressure variation. The Ammonium Perchlorate (AP) was obtained and ground into fine powder with the particle size ranging from 63 to 125 μm. The propellant strands were prepared with proportions by mixing AP with the binder (Hydroxyl Terminated Polybuta...

Temperature Sensitivity of the Diphtheria Containing Vaccines

Vaccine management is basically all the actions related to handling of vaccines at the country level from the moment they arrive until the moment they are used. These include arrival and acceptance procedures, appropriate temperature monitoring, ensuring sufficient storage volume, maintaining standards of buildings, equipment and vehicles, effective stock management, vaccine delivery systems as...

EFFECT OF NANO SiC ADDITIVE ON MCMB-SiC COMPOSITE FABRICATION VIA MOLTEN SILICON INFILTRATION

C-SiC composites with carbon-based mesocarbon microbeads (MCMB) preforms are new type of highpreformance and high-temperature structural materials for aerospace applications. In this study MCMB-SiC composites with high density (2.41 g.cm-3) and high bending strength (210 MPa,) was prepared by cold isostatic press of mixed mesophase carbon powder derived from mesophase pitch with different amoun...

Nano-BaSO4: a novel antimicrobial additive to pellethane

Hospital-acquired infections remain a costly clinical problem. Barium sulfate (BaSO4, in micron particulate form) is a common radiopacifying agent that is added to catheters and endotracheal tubes. Due to the recently observed ability of nanostructured surface features to decrease functions of bacteria without the aid of antibiotics, the objective of this in vitro study was to incorporate nano-...
