Lanthanum: It's Applications and Uses

Humankind has been performing the use of metals in a diverse area and applications. Earlier times, humanity used these metals for producing hunting weapons and defending oneself. Nowadays applications extend their use in industrial area, multiple robotic equipment, defense ammo, etc. Therefore, we encounter use of lanthanum in many areas.
Lanthanum is one of the rare earth elements. It is a soft, ductile, silvery-white metallic chemical element with symbol La and atomic number 57. Lanthanum was first found by the Swedish chemist Carl Gustav Mosander. When we examine benefits of lanthanum, we encounter interesting area.

* Lanthanum element does not have commercial uses, but its alloys are so popular. Lanthanum is used in large quantities in nickel metal hydride rechargeable batteries for hybrid automobiles. Today, a Toyota Prius hybrid car on the road carries with it about 4.5 kg of lanthanum. These cars have nickel-lanthanum hydride batteries. Also, these batteries are about twice as efficient as the standard lead-acid car battery.

* The best-known use for mischmetal alloy of Lanthanum is; as a ‘flints’ for cigarette lighters.

* Lanthanum has application in glass and ceramic manufacturing. It is used in making special optical glasses, such as infrared absorbing glass. Because of its high refractive index and low dispersion indices Lanthanum is used as doping agents in camera and telescope lenses.

* Lanthanum is also used in alloys such as high strength alloy steels

* In catalysis Lanthanum is used in petroleum cracking and has also catalytic applications in chemical industry.

*Lanthanum is used in some pool products to reduce the level of phosphate nutrients that feed algae.

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 ...
