- 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

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 ...

New Way of Deaf-Mute Communication with 3D Graphene

Image retrieved from: http://blogs.rsc.org/cc/2016/09/01/3d-graphene-adds-dimension-to-deaf%E2%80%93mute-communication/ Chinese scientists have developed wearable electronic device with conductive 3D graphene structure to translate sign language into written text. This technology can be applied by injecting graphene ink from a syringe under printed electronic field. For medical field, such as adhesive patches which determine heart, brain signal and neural activity, wearable and bio-integrated medical devices are very important. Due to noticeable properties of cast graphene, for example a 2D honeycomb lattice, excellent mechanical and electrical behaviors, Graphene has an important material in warble technology. However, it is difficult to preserve advantages of Graphene material in a 3D material which has an information about forces from every angle. Yanlin Song  and co-workers at the University of the Chinese Academy of Sciences, Beijing, and Shenyang Jianzhu University...
