Density Functional Theory (Dft) Study On The Hydrolysis Behavior Of Degradable Mg/Mg Alloys For Biomedical Applications, Marjan Nezafati
Density Functional Theory (Dft) Study On The Hydrolysis Behavior Of Degradable Mg/Mg Alloys For Biomedical Applications, Marjan Nezafati
Theses and Dissertations
Magnesium-based (Mg and/or Mg alloys) materials possess many advantageous physicochemical/biological characteristics such as good biocompatibility and similarity of the mechanical properties to the human bone tissue, which renders this material a promising candidate for the biomedical and implant applications. One of the most attractive features of Mg-based materials is the degradability in the physiological environment. With the burst of research on the biodegradable materials for the healthcare device applications, Mg and its alloys attracted a strong attention in the bioengineering field in recent years. However, the major limitation of applying Mg-based materials to biomedical applications is the fast degradation/corrosion rate …

System For Detection Of Defects In Cables Of Bridge Structures, Emad Ismail Abdel Salam
Theses and Dissertations
Over the last 75 years, many cable-supported bridges have been built in America, Europe, Asia and other parts of the world. However, over the years these bridges have aged and been exposed to environmental conditions such as rain, snow, de-icing and harmful chemicals. These conditions cause various levels of deterioration in bridges, particularly corrosion. Corrosion causes a loss of cross-section in the steel, adversely affecting the bridge's capacity to carry its service loads, and can possibly cause bridge failures. Although many methods have been attempted to inspect these bridges, most have offered limited success. In the recent years, it has …
