Studying the effect of Different wt % AL2O3 Nanoparticles of 2024Al Alloy / AL2O3 Composites on Mechanical Properties
Al-Khwarizmi Engineering Journal, 2019Co-Authors: Al-alkawi Hussain Jasim Mohammed, Abthal Abd Al Rasiaq, Mamoon A. A. Al JaafariAbstract:The nanocompsite of alumina (Al2O3) produced a number of beneficial effects in alloys. There is increasing in resistance of materials to surface related failures , such as the mechanical properties , fatigue and stress corrosion cracking .The experimental results observed that the adding of reinforced Nanomaterials Type Al2O3 enhanced the HB hardness, UTS, 0.2 YS and ductility of 2014 Al/Al2O3 nano composites . the analysis of experiments, indicated that The maximum enhancement was observed at 0.4 wt.% Al2O3. The ultimate improvement percentage were 15.78% HB hardness, 18.1% (UTS), 12.86% (0.2 YS) and 25.71% ductility. These enhancements in the above properties maybe to high dislocation density resulting in good bounding between Al2O3 and metal matrix.

Self-assembled Nanomaterials Type Layered Double Hydroxides Antibiotics Used as Drug Delivery Vectors
Revista de Chimie, 2017Co-Authors: Letitia Doina Duceac, Liviu Stafie, Elena Ariela Banu, Oana Paduraru, Gabriela Calin, Madalina Irina CiuhodaruAbstract:Due to their biocompatibility, Nanomaterials Type layered double hydroxides (LDHs) development has attracted many researchers attention especially in medical area using them as drug delivery vectors. Their efficiency is due to the drug controlled release from the interlayer space of LDHs matrices. The controlled drug delivery characteristic is due to the reduction of drug concentration variations and maintains the desired level of drug concentration for long time. Furthermore, this action limits adverse effects and reduces the therapy duration, enhancing bactericidal activity and leading to an effective treatment. This work highlights the synthesis and characterization of hybrid structures Type LDHs- tobramycin having application as antibacterial factor against Pseudomonas aeruginosa. The obtained self-assembled structures were morphologically characterized in order to point out the drug-interlayered products. Results indicate superior properties of MgAlLDHs and ZnAlLDHs behaving as host for a wide variety of molecules generally and, in our case, for tobramycin as guest.
