Abstract
The advanced ceramic ZTA (biolox) is used in artificial joints. ZTA (biolox) was synthesized and modified by using (0.25, 0.5, 0.75, and 1) wt. % of CaF2 and MgO. The sol-gel technique was utilized to make a nanocomposite powder using aluminum, zirconium, strontium, and chromium salts. The characterization, physical, mechanical, and biological properties were studied. The results show that CaF2 improved the mechanical properties of ZTA except for hardness, which decreased with increasing CaF2 concentration from ~16.84 to 14.50 GPa. However, MgO has two effects on ZTA properties depending on its concentration: below 0.75 wt.%, the effect enhances ZTA properties, but above this concentration, the effect reverses and causes a significant reduction in properties.

Abstract
In this study, different laminated composite materials were suggested for modifying the prosthetic socket in order to increase its life and make it more comfortable for its user. Seven laminated composite materials were prepared by using the vacuum molding technique. The matrix material is Lamination80:20 (PMMA) and reinforced by (hemp, Carbon, Glass, Kevlar, and Perlon) fibers with different numbers of layers. The experimental work included mechanical, physical, and miscibility tests. After comparing between laminated composites, hybrid lamination consisting of (4hemp plus 2carbon) is considered to have best mechanical and physical properties such as tensile strength, modulus of elasticity, flexural strength, flexural modulus, max. shear stress, compression strength, impact strength, fracture toughness, and hardness. In addition, it has a lower percent elongation and creep strength than the hybrid laminations made of (4hemp plus 2kevlar) and (4hemp plus 2glass).

Abstract:
Merging membrane technology with the photocatalytic activity of nanomaterials is a promising approach towards minimizing membrane fouling consequences. In this work, nanocomposite membranes were synthesized by non-solvent induced phase inversion process, by immobilizing Tungsten Oxide (WO2.89) nanoparticles (NPs) in polyether sulfone matrix. The results showed that membrane's properties and pollutants' rejection, flux recovery ratio, and flux were improved after NPs addition. It was also found that after exposing the samples to UV light irradiation, the flux recovery ratio was improved for the NPs modified membranes compared to neat membranes. It was found that the flux value at longer time for the NPs modified membranes after irradiation were higher compared to the modified membranes with same NPs loading without irradiation.

Abstract
This thesis lies in two main parts; experimental and analytical work. In the first part, an analytical model was prepared to analyze and calculate the dynamic behavior of the random copolymer polypropylene pipe (PP-R) conveying fluid, using Integrated Transformation Techniques (ITT). In the second part, a semi-active control system was designed using Proportional-Integral-Derivative (PID) controller, by employing the shape memory alloy (SMA) wires, made of nickel titanium alloy (Nitinol), to mitigate the vibration of the pipes caused by the fluid flowing inside them. The results demonstrated that there was a large increase in pipe deflection and a significant decrease in natural frequency with increasing temperature and aspect ratio under different fluid velocities. The results manifested that there is a reduction in the level of vibration (about 75%) was obtained by thermal activation of the shape memory wires which leads to alter the dynamic response of the pipe.

Abstract
This work treats the transverse vibration for a polypropylene random copolymer (PP-R) pipe, conveying fluid. The pipe was placed at different support angles and subjected to variant temperatures. It was revealed that the thermal effects in the pipe are a very important factor and more significant in comparison with the internal fluid velocity and the inclination angle has a larger impact on vibration characteristics at a higher aspect ratio.

"Dynamic response of inclined pipe conveying fluid under thermal effect"
Abstract
This work is aimed at studying the dynamic response of polypropylene random-copolymer (PP-R) pipes caused by fluid flow inside them. The results demonstrate that there is a significant increase in pipe deflection with increasing temperature and aspect ratio. and fluid velocity, while a decrease in the deflection value is observed with an increase in the angle of inclination in the range of 0-90°.

The MXene was employed to enhance the ZnO nanoparticles and for the synthesized heterostructured photocatalyst to photodegrade harmful pharmaceuticals under simulated sunlight. The MXene was hydrothermally prepared from a MAX phase (Ti3AlC2) by utilizing NH4HF2 as an etchant, followed by chemical synthesis of a ZnO/TiO2 MXene photocatalyst. XRD, FTIR, FESEM, UV-vis DRS, TEM, and BET analysis were used to analyze the prepared photocatalysts. The results showed that ZnO-TiO2 MXene had excellent performance in the elimination of the ceftriaxone sodium and carbamazepine compounds, with an evaluated efficiency of 99.4% and 99.6%.
