Abstract
Researchers investigated new body armor technologies in response to the development of new weaponry. This research aims to create a hybrid composite and test it experimentally and theoretically under ballistic impact. Body armor is designed with multiple layers. The first design consisted of rubber/ceramic/ (Al2O3) rubber/20 layers of UHMWPE reinforced epoxy/rubber. Where rubber and ceramics represent the first line of protection against lead, followed by the intermediate compound. Then rubber was used for the back layer. The second design consisted of ceramic (Al2O3)/10 layers of UHMWPE reinforced epoxy/steel/ceramic (Al2O3)/10 layers of UHMWPE reinforced epoxy/steel. Where the area of both armor was 900 cm2 and an AK-47 bullet was fired at a distance of 15 m at a speed of 730 m/s, and another 9 mm pistol bullet was fired at a distance of 5 meters and a speed of 310 m/s against both armors. Where the results of the ballistic examination showed that the first and second armor were punctured and penetrated by an AK-47 bullet, while the second armor stopped the 9 mm pistol bullet without a hole, ANSYS Autodyn R21 was used to simulate the ballistic effect..

Abstract
The present study provides an experimental study for producing geopolymer paste and examines metahalloysite-based geopolymer with two types of alkaline solutions: sodium hydroxide (NaOH) and potassium hydroxide (KOH) mixed with sodium silicate. The nanomaterials were then added to reinforce the geopolymer by weight of metahalloysite (1%, 2%, and 3%) of these three types. The nanomaterials used are nano clay, Multi-walled carbon nanotubes, γ-Al2O3 and Hybrid. After aging for 28 days, the samples were tested under compression, hardness (shore D), Field Emission Scanning Electron Microscopy, Energy-dispersive X-ray spectroscopy, X-ray Diffraction, Fourier transform infrared spectroscopy, and Differential Scanning Calorimetry. Nano-hybrid exhibited the highest compressive strength and hardness. The morphology was homogeneous and without pores due to additives of nanomaterials that act as fillers in the matrix.

Abstract
This study aimed to enhance the biocompatibility and corrosion resistance of commercially pure titanium substrate using the most modern deposition technique utilized for biomedical applications, Electrostatic Spray Deposition (ESD). To construct the bio composite-polymer base coating, different percent’s (2, 6, and 10) wt.% of Hydroxyapatite (HAP), Nickel Oxide (NiO), and Niobium Oxide (Nb2O5) powder were combined with (98, 94, and 90) wt.% of polymethyl methacrylate (PMMA) powder coating. And, the hybrid coatings groups were constructed by combining different percents of (NiO with HAP) and (Nb2O5 with HAP) with 90 wt.% of PMMA. The FESEM, EDS mapping, XRD, FTIR, contact angle, and anti-bacterial tests demonstrated that the coating layer was consistent, crack-free, hydrophilic, and had good inhibition of bacterial growth. While the in vitro experiments prove that in simulated body fluid for 30 days at 37°C, the coating layers exhibited a significant capacity for forming apatite crystals on their surfaces indicating high osseoconductivity and the immersion test showed high corrosion resistance. Also, Vickers microhardness and scratch hardness showed that the ceramics particles improve the polymeric coating hardness and adhesion.

Abstract:
This research aims to manufacture two types of contact lenses (hard and soft), study the effect of adding aloe vera gel on the composition and properties and know the effect of covering the lenses with a thin layer of colloidal silver. A hard lens was prepared from poly methyl methacrylate and a soft lens was prepared by polymerization of many monomers to form a hydrogel. Samples were mixed with different weight percentages of aloe vera gel. Several tests were performed on the resulting lenses before and after adding aloe vera gel and also before and after covering them with colloidal silver. All samples showed great resistance to Staphylococcus aureus, and the effect of aloe vera was strongly observed. Adding aloe vera gel to contact lenses helps enhance their performance, as the degree of homogeneity is very high.

Abstract
The thesis aimed to study the mechanical properties and microstructure of welded tubes (similar and dissimilar welding).(T22-T22),(T91-T91),(T91-T22) by using different filler metals (ER90S-B3,ER90S-B9,ERNiCr-3) used in steam boilers in electric power plants. The welding process (GTAW) was carried out for the pipes, taking into account the heat treatment before welding and after welding and the (purging process for root pass only) by argon gas. Also, six tests were conducted to examine the microstructure, mechanical properties and effectiveness of the weld, which include: radiography, optical microscopy, electron microscopy (SEM), energy dispersive spectroscopy (EDS), hardness test (HV), tensile test at high temperature ( 550) degrees Celsius to simulate the real conditions of the pipes inside the boiler. The results of the work in the similar welding (T22-T22) showed that when using the filler metal (ER90S-B3), the highest tensile strength (419 MPa) was obtained with elongation (20%) compared to the other sample when using filler metal (ERNiCr-3), tensile strength (379 MPa) with elongation (21%) was obtained. The highest hardness value (230 HV) was obtained in (HAZ of T22) in dissimilar welding when using filler metal (ER90S-B3) compared to other samples when using filler metal (ERNiCr-3) was obtained (205 HV), and when using filler metal (ER90S-B9) was (206 HV). Also, the tensile test showed that the fracture site of the samples it varies with the filler metals used. The efficiency of the welded samples was also extracted, and the efficiency was (100%) for all welds with similar and dissimilar welding.

Abstract
This research aims to prepare PVA/NiTi composite nanofibers by electrospinning technique, using a new method to produce NiTi nanoparticles (by assaying the NiTi alloy produced by sintering using a vacuum furnace )by laser, as NiTi nanoparticles were used in the electrospinning process. . The resulting NiTi nanoparticles were analyzed by X-ray diffraction (XRD), (SEM), these fibers were added to Portland cement and the compressive and bending properties were examined and it was noted that the addition of fibers led to a positive improvement in the compressive strength of the cement.
