We report a simple method for the micro-nano integration of flexible, vertically aligned multiwalled CNT arrays sandwiched between a top and bottom carbon layer via a porous alumina (Al(2)O(3)) template approach. The electromechanical properties of the flexible CNT arrays have been investigated under mechanical stress conditions. First experiments show highly sensitive piezoresistive sensors wi...

Blending ultrafine-grained microstructure with other added reinforcement elements that can provide good strength-microstructural integrity is the primary metallurgical target for any developed composite to exhibit its maximum strength at reduced cost and energy in aerospace application. Such nano-reinforced aluminium alloy composites are processed through addition of nano alumina using powder m...

Carbon fiber composites have become popular in aerospace structures and applications due to their light weight, high strength, and high performance. Recently, scientists have begun investigating hybrid composites that include fibers and particulate fillers, since they allow for advanced tailoring of mechanical properties, such as improved fatigue life. This project investigated a hybrid carbon ...

In this study, hydrothermal synthesis was used to prepare α-Ni(OH) 2 , which is a steady-state photocatalytic material. Furthermore, ball milling for the 1:1 loading of with nano-alumina (Al O 3 ), hexagonal boron nitride (h-BN), and activated carbon (AC). The performances these four materials in degradation fracturing flowback fluid were investigated under synergistic catalytic effect ozone. r...

<p>The amount and type of waste are increasing due to population growth. Many harmful materials have been in the atmosphere for a very long times. This causes crisis disposal thereby contributes environmental issues. Recycling concrete manufacturing not only offers resource producing top standard but also aids correctly addressing issue disposal. Due leftover ceramic powder's high resista...

highly sinterable alumina nano-powders have been synthesized by a sol-gel combustion method with glycine asfuel. the preparation involved the thermal decomposition of a chelating agent (fuel)-nitrate gel and theformation of amorphous precursors. the nanopowders calcined at 1100°c were characterized by x-ray powderdiffraction (xrd) and scanning electron microscopy (sem). it was found that the ch...
