evolution explained is not boring at all she finds a way to make it actually fascinating. Another interesting chapter is the first chapter in the book. It is about a man who training for a marathon. Through his exercising he takes a lot of vitamin and iron supplements. Towards the end of his regiment he starts feeling sick. But he is stubborn and refuses to go to the doctor‚ he claims he will kick it soon. Finally his wife convinces him to be checked out by a professional. The doctor comes to the conclusion

Rust is the name given to the common compound (Fe2O3) when iron combines with oxygen to form iron oxide. Rusting is known as corrosion of iron and its alloys such as steel or cast irons. Rust can be found on cars‚ metal pipes‚ aircrafts and anywhere with iron‚ copper and aluminium. Corrosion can be concentrated locally to form a split or crack‚ or it can extend across a wide area which causes corroding on surfaces. Because corrosion is a diffusion-controlled process‚ it occurs mainly on exposed surfaces

Engineering Materials Msc. Shaymaa Mahmood Introduction to Eng. Materials : Since the earliest days of the evolution of mankind ‚ the main distinguishing features between human begins and other mammals has been the ability to use and develop materials to satisfy our human requirements. Nowadays we use many types of materials‚ fashioned in many different ways‚ to satisfy our requirements for housing‚ heating‚ furniture‚ clothes‚ transportation‚ entertainment‚ medical care‚ defense and all the

anode. My experiment is aimed at testing the corrosion of 2 different types of nails in a certain molar solution of salt water in anticipation of determining which of the two would be more suitable for beachside residencies. I hypothesized that the iron nails would almost double in content of rust as the molarity of the solution they’re soaked in increases. The galvanized nails hopefully will end up with limited amounts of rust in all solutions. The activity series plays a major role in corrosion

Fribourg‚ Perolles‚ CH-1700 Fribourg‚ Switzerland ´ ´ Abstract Carbon nanotube composite materials were produced by catalytic decomposition of gaseous carbon sources Žsuch as carbon monoxide or hydrocarbons. on nanometer-size metal clusters of iron‚ cobalt and nickel embedded in matrices of inert metal oxide particles. The resulting multiwalled carbon nanotubes are several micrometers long with tube diameters ranging from 5 to 20 nm. A fluidised bed reactor was developed for a large-scale synthesis

either ferrous or non-ferrous. So what is the difference between ferrous and non-ferrous metals? It is the most frequently asked questions. Shortly speaking‚ ferrous metals and alloys contain iron while non-ferrous materials do not. Ferrous metals include mild steel‚ carbon steel‚ stainless steel‚ cast iron‚ and wrought iron. These metals are primarily used for their tensile strength and durability‚ especially mild steel which helps hold up the tallest skyscrapers and the longest bridges in the world. Besides

FePO4 is widely recognized as iron phosphate. It has a great similarity to quartz that has trigonal lattice structure‚ space group P3121 (group no. 152). When the condition is under 980K‚ FePO4 becomes α-FePO4 that has trigonal lattice structure too and space group P3121 (group no. 152). In this form‚ phosphate‚ iron‚ and oxygen take up Wyckoff position 3a‚ 3b‚ and 6c correspondingly. Every phosphate or iron atom is united to four oxygen atoms‚ composing corner-connected FePO4 and PO4 tetrahedral
