Uses of Iron (Fe) Nanoparticles

Properties:
Iron is a chemical element with atomic number 26. Iron is a metal in the first transition series. Iron is one of the most common elements in the world. Iron is found in much of inner and outer core of Earth. Pure iron has a silver color and it conducts electricity and heat well. Iron readily reacts with many other elements, so Iron is hard to find its pure form. Iron naturally occurs as iron ores, such as magnetite, siderite, hematite.
One of the remarkable traits of the iron is that it is highly magnetic. In a strong magnetic field any part of iron can be easily magnetized. Iron is also believed that the earth’s core holds around 90 percent of iron.
Iron is a crucial element for all living things and is nontoxic. Iron is the fourth most abundant element.
The bad side of the iron’s properties is that Iron has a tendency to rust. However, if coated with other elements such as zinc, it becomes a pretty effective material. The most effective method is the use of steel.

Applications:
Iron is used in manufacturing steel that is utilized in civil engineering (girders, reinforced concrete) and in manufacturing. Steel has many types and each type holds different properties, making it useful in even broader area of applications. Alloy steels are carbon steels with additives like nickel, chromium, etc., that are stronger than carbon steels and are used in applications including electricity pylons, bicycle chains, bridges, cutting tools, gun barrels. Stainless steel does not rust and if alloyed with other metals such as nickel it is readily used in architecture, cutlery bearings, jewelry, surgical instruments. Cast iron is used for pipes, pumps and valves. Magnets can be made of iron alloyed with other elements. Iron can also be used as a catalyst (Haber process for making ammonia...).

Improving Dialysis Process with Graphene

Researchers from Mechanical and Electrical Engineering Departments of MIT recently showed that graphene is a powerful material candidate for use in the dialysis systems (such as hemodialysis machines in medical institutes for filtering human blood). In order to prepare graphene as a dialysis material, researchers used a procedure opposite to the general treatments that nanotechnology people use. Dialysis is a process of filtering different solutions such as human blood by a membrane in order to remove waste molecules, drugs, chemical residues from the solution. In some cases, the process can be used for purification of chemicals or isolation of different molecules for medical diagnosis. It is an essential process for scientists especially in the medical operations.

Rundown about Silicon Oxide Wafer

The main insulating material used in micro-technology is Silicon Dioxide, which in chemical symbols is written as SiO2. In semiconductor technology, SiO2 thin film layers are mainly used as dielectric material film in transistors, capacitors (DRAM) or flash-memories. Silicon Oxide Wafers are produced using crystallization, solid state and other ultra-high purification processes such as sublimation. This process forms a cylindrical ingot, which is then sliced and polished to form wafers. Thermal oxide is a kind of "grown" oxide layer, compared to CVD deposited oxide layer, it has a higher uniformity, and higher dielectric strength, it is an excellent dielectric layer as an insulator . In most silicon- based devices, thermal oxide layer play an important role to pacify the silicon surface to act as doping barriers and as surface dielectrics. The simplest way to produce an insulating silicon oxide layers (SiO2) on silicon wafers is to oxidize silicon with oxygen, which ...
