- Lutetium is a chemical element with symbol Lu and atomic number 71
-Origin of name of Lutetium is Lutetia, the ancient name of Paris.
- Lutetium is the last element in the lanthanide series, and is traditionally counted among the rare earths.
- Lutetium is a silvery white metal, which resists corrosion in dry, but not in moist air.
- Lutetium is not a particularly abundant element, although it is significantly more common than silver in the earth's crust.
- Lutetium is considered to be non toxic.
- Lutetium tarnishes slowly in air and burns at 150 oC to the oxide.
- Lutetium is the densest and hardest of the lanthanides.
- When present in compounds, lutetium exists usually in the trivalent state, Lu3+ Most of its salts are colorless.
- Lutetium oxide is used to make catalysts for cracking hydrocarbons in the petrochemical industry.
- 177Lu is used in cancer therapy and because of its long half-life, 176Lu is used to date the age of meteorites.
- Lutetium oxyorthosilicate (LSO) is currently used in detectors in positron emission tomography (PET). This is a noninvasive medical scan that creates a three-dimensional image of the body’s cellular activity.
- Lutetium is not found free in nature but is found in a number of minerals, mainly monazite

Hydroxyapatite Nanopowders and Their Applications

Hydroxyapatite, is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4 ) 3 (OH). Pure hydroxyapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis. Hydroxyapatite Nanopowder/Nanoparticles (50 nm, 99.95+%)  has been widely used as a biocompatible ceramic in many areas of medicine, but mainly for contact with bone tissue, due to its resemblance to mineral bone. In mammals, the skeleton presents a carbonated and partially substituted apatite, based on nanocrystal aggregates, and associated with collagen, building up 3-D structures present in various bone tissue conformations like trabecular or cancellous bone. There has been growing interest in developing bioactive synthetic ceramics that could closely mimic natural apatite characteristics. As mentioned before,  Hydroxyapatite Nanopowder  is the main inorganic constituent of bon...

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 ...
