Copper (Cu), chemical element, a reddish, extremely ductile metal of Group 11 (Ib) of the periodic table that is an unusually good conductor of electricity and heat.Copper is found in the free metallic state in nature. This native copper was first used (c. 8000 bce) as a substitute for stone by Neolithic (New Stone Age) humans.Metallurgy dawned in Mesopotamia as copper was cast to shape in
Researchers first cover a small silicon wafer with a thin layer of water-soluble organic film and deposit pentacene molecules upon it until a layer about 50 nanometers thick has formed. Then, by irradiation with low-energy electrons, the topmost three to four levels of pentacene molecular layers are crosslinked.

SIMS Analysis of Nitrogen in Silicon Carbide Using Raster Change Technique. WHITE PAPER. ABSTRACT. Today’s state of the art silicon carbide (SiC) growth can produce semi-insulating crystals with a background doping around 5×10 15 atoms/cm 3 or lower. It is essential to have an accurate measurement technique with low enough detection limit to
Carbon''s wiki: Carbon (from Latin: carbo "coal") is a chemical element with syol C and atomic nuer 6. It is nonmetallic and tetravalent —making four electrons available to form covalent chemical bonds.It belongs to group 14 of periodic table .Three isotopes occur naturally, 12C and 13C being stable, while 14C is a radionuclide, decaying with a half-life of about 5,730 years.
Indeed, boron nitride might be the hardest known substance. Both compounds have high melting points: for boron carbide 2,350°C (4,300°F) and for boron nitride more than 3,000°C (5,400°F). The above-mentioned properties make boron carbide and boron nitride valuable as abrasives and refractories. A grating is a fine material used to polish or
