Applying Nanocomposite Coatings To Improve Orthopedic Alloys By Using Multiple Flame Spray, Shahad Jabbar, Niveen Abdulkader, Payman Ahmed
Engineering and Technology Journal
Due to their excellent mechanical and biocompatibility characteristics, CoCr-based alloys are frequently employed in orthopaedic implant applications. It is necessary to maximize their general characteristics, corrosion resistance, and ion release. Despite several benefits, coating with torch flame spray has weaker adherence. As a result, powder metallurgy was employed to combine Si and Nb elements with CoCr alloys. CoCrNb and CoCrSi alloys were sprayed with multiple torch flames to apply two different kinds of Nano-coatings (A: 75% HAP+ 25% SiC, and B: 75% Zeolite+ 25% ZrO2). In two samples, alloying elements Nb and Si were added at a concentration of 5 …

Clathrate-Based Recovery Of Sulfuric Acid From Spent A Cid, Najlaa Lazim, Riyadh Almukhtar
Clathrate-Based Recovery Of Sulfuric Acid From Spent A Cid, Najlaa Lazim, Riyadh Almukhtar
Engineering and Technology Journal
Recently, the applications of hydrate phenomena in industrial processes have been increasing. A clathrate or hydrate is a solid, ice-like compound that forms when water/guest is mixed under certain conditions. Hydrogen water molecules bond with the guest molecules to form a crystal lattice. Different guests can form the Clathrate (e.g., gases or liquids). Dilute Sulfuric acid is usually generated at different industrial plants, and these dilute acids are considered waste because they cannot be reused again. Many treatment processes handle this environmental problem, like electrochemistry, precipitation, adsorption, membrane filtration, and ion exchange. Although such processes have significant operational advantages, their …

Artificial Neural Network-Based Transmission Power Control For Underwater Wireless Optical Communication System, Omar Mohammed Salim, Salah Adnan, Ammar Mutlag
Artificial Neural Network-Based Transmission Power Control For Underwater Wireless Optical Communication System, Omar Mohammed Salim, Salah Adnan, Ammar Mutlag
Engineering and Technology Journal
Several scientists have proposed using an underwater wireless optical communication system (UWOC) to deliver high-speed data services using the abundant optical spectrum. However, wireless optical signal propagation faces an antagonistic environment when using undersea channels due to various factors like scattering, absorption, turbulence, and optical link misalignment between the transmitter and the receiver. These factors will attenuate the optical signal and lead to degrading system performance. To reduce these factors impact on the communication system's performance, transmitted optical power (OTP) should be increased. Since the UWOC system is battery-powered, increasing OTP will consume more electrical power. Therefore, it is necessary …

Engineering and Technology Journal
The coherent oscillation of electrons at contact among a dielectric and metal when the metal is exposed to incoming plasmon is known as “surface Plasmon resonance”. To achieve the best surface plasmon resonance (SPR) signal, several aspects must be considered, including the excitation wavelength, the sort of metals used, and the thickness of the metal layer. The modification of the surface plasmon resonance (SPR) depending on the thickness of metallic gold was investigated in this study. The reflection spectrum is determined as a function of metal thickness and dielectric medium (air), which is fixed in this case, and measuring the …

316L stainless steel alloys are extensively used in orthopedic applications for the fixations and substitutions of defective bone tissues in the human body because of their excellent combination of mechanical and biological behavior. However, just like other metallic implants, they tend to release some toxic ions that may lead to serious health issues. Therefore, this study attempts to increase the alloy's resistance against corrosion while maintaining its good mechanical properties by applying a modified coating layer of PMMA-based composites titanium carbide as reinforcement material using dry electrostatic spray deposition (ESD) under constant conditions (25 kV, 15-20 cm distance, compressed air …
