    Abstract: The research into alloys, specifically titanium and aluminum alloys (Ti & Al), has rapidly growing technological importance. The combined research into Ti-Al alloys in the field of powder metallurgy has advanced the fabrication of a part with high compressive strength, low relative density and material properties in addition to being a cost-effecti...

    Abstract: The challenging issues in ceramic tiles are low mechanical strength, thermal discomfort and high production costs. And in most efforts to improve strength, emphasis has been placed on minimization of quartz content in the ceramic tiles formula. This is due to β-α phase inversion of quartz which occurs at 573°C during cooling resulting to the develo... Show More
  • Synthesis and Properties for Benzotriazole Nitrogen Oxides (BTzO) and Tris[1,2,4]triazolo[1,3,5]triazine Derivatives

    Abstract: Herein we first report a novel method of synthesis fused ring nitrogen-enriched compounds by intramolecular cyclization reaction. Some of them were characterized by IR, 1H and 13C NMR spectroscopy. Most of them exhibit outstanding positive heat of formation (155-376 kJ/mol). Densities of these compounds fall in the range between 1.7321-1.8847 Show More
  • Storage and Installation of Granite Plugs at the Intersection of the Corridors of the Cheops Pyramid

    Abstract: The article investigates the design of the intersection of the Descending and Ascending Corridors in the pyramid of Cheops. Until now there is no convincing indication of the storage location for the granite plugs, and an explanation of how they were delivered and installed. Also, the question remains, how the builders managed to install them so ti... Show More
  • Preparation and Characterization of Porous Scaffold Composite Films by Blending Carboxymethyl Chitosan and Gelatin for Tissue Engineering

    Abstract: In this research work, gelatin-carboxymethylchitosan (CMC) based biodegradable composites films were prepared by solution casting method. Chitosan from waste prawn shell was the basic raw materials of CMC synthesis. Five sets of CMC-gelatin composites (5-25 wt% CMC) along-with pure gelatin were prepared in solution casting method. Incorporation of ... Show More
