Synthesizing a nanocomposite tungsten carbide-cobalt metal oxide

Al-Hazza A.A., Kuwait Institute for Scientific Research, KW

In this work a nanocomposite WC-Co metal oxide was synthesized by using a solid state mixing techniques. Certain metals oxide were used in this process (Al, Mg, Si, and Zr) to enhance the property of [...]

Microscopic Identification of Micro-Fractures and Deterioration In Arid Environments Of Pro-Oxidant Polyethylene (PE) Specimens Utilizing State of The Art Thermal and Morphological Experimental Protocols

Al-Salem S.M., Al-Hazza A.A., Al-Rowaih A.A., Al-Dhafeeri A.T., Kuwait Institute for Scientific Research, KW

Pro-oxidant filled polyethylene (PE) specimens in standard and internationally accepted dimensions and size, were exposed to arid natural and accelerated weathering conditions. The American Society for Testing and Materials (ASTM) protocols for weathering were followed, [...]

Synthesis of Titanium Nanoparticles with Controlled Size Variation by Physical Vapor Deposition

Alzubi F.G., Kuwait Institute for Scientific Research, KW

In this work, we were able to control the diameter of the formed Ti nanoparticles by varying the deposited film thicknesses to different values 2, 4, 6, 8, and 18 nm. Size, distribution, topography, and [...]

Effect of length and radius of singlewall carbon nanotube on its mechanical properties

Alzubi F.G., Cosby R., Kuwait Institute for Scientific Research, KW

A first principles atomistic calculations and analysis of Young’s modulus for short arm chair carbon nanotubes with different lengths and radii is]]are reported. The atomic forces and total energies were computed for the carbon nanotubes [...]

Nanomechanical and Morphological Characterizations of Spark Plasma Sintered WC- 5Co-1Cr-3MgO-0.7VC-0.3Cr3C2 Nanocomposite Powders Prepared by Solid-State Mechanical Mixing Technique

Sherif El-Eskandarany M., Al-Hazza A., Alduweesh A., Kuwait Institute for Scientific Research, US

WC-Co-based composites possess unique and useful properties that make them desirable materials for wide range of industrial applications such as tips for cutting and drilling tools, wear resistant parts in wire drawing, extrusion and pressing [...]

Synthesizing and Consolidation of Mechanically-Induced Solid-State Reacted Ti50C50 Nanopowders and Subsequent Consolidations

Sherif El-Eskandarany M., Al-Hazza A., Shaban E., Alduweesh A., Al-Rowayeh A., Kuwait Institute for Scientific Research, KW

In contrast to the industrial approach for preparing such important materials, we have succeeded to synthesize a single phase of Ti50C50 nanopowders, using high-energy ball milling technique. The ball milling procedure took place at ambient [...]
