Background: Corrosion control of magnesium for biomedical applications can be achieved by two means: deposition of protective coatings that isolate the surface from aggressive human body environment, and alloying the base metal with biocompatible elements that stabilize the surface against deterioration. Objective: This contribution reviews recent research towards efficient corrosion protection of magnesium and its a Read More

Background: The nature of graphene makes it a highly sought after material for transparent and non transparent electrodes and double electrode designs for supercapacitors. It has been well documented that graphene can be used for transparent electrodes in flat panel displays, tough screens, and solar cells. In this case of supercapacitors, transparency is less important than energy storage capacity. However, even in t Read More

Background: Raw natural gas, one of the most important fuel sources worldwide, contains high level of CO2, which must be removed to avoid problems like pipeline corrosion, compression cost and reduction of heating value. The three main technologies used to separate CO2 from natural gas include cryogenic distillation, amine absorption and membranes. Membrane technologies have various advantages especially for off Read More

Background: Exposure of newly synthesized biomaterials and drugs to humans needs a strict monitoring to minimize or prevent the after effects. One of the commonly used tests in ensuring the safety of new products is cytotoxicity testing. Cytotoxicity testing enables to observe cell growth, viability and morphological effects of biomaterials in vitro. Considering the advantages of the cytotoxicity tests, researchers employ this Read More

Background: Bismuth sulfide (Bi2S3) has many smart physical and chemistry properties and potential advantages in optical and electrical applications. To further enhance the application property, many studies had been performed. Objective: This work explained the manufacturing and potential application of the Bi2S3 materials with various cation dopings in recent literature and patent and then focused on the depositio Read More

Background: Research in the field of orthopedics is trying to evaluate the materials for an artificial joint with minimum wear volume loss, so as to extend the life. Various material combinations are proposed to overcome this issue. Silicon nitride (Si3N4) is non-oxide ceramic suggested as a new alternative for hip/knee joint. Objective: In this paper, an attempt has been made to evaluate the optimum proportion of load and % vol Read More

Background: Hydrogen energy is a solution for the energy crisis. As it is known, the result of hydrogen combustion is water vapor. This means that there is no pollution. Objective: This study investigates hydrogen production of pure aluminum (Al) and aluminum -silicon alloy (Al-Si). The investigation has been processed in the presence of 10% and 15% of sulphuric acid (H2SO4) at room temperature50°C. Methods: Weigh Read More
