Iron(III) oxide - Wikipedia

2019-5-13 · Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare; and iron(II,III) oxide (Fe3O4), which also occurs naturally as the mineral magnetite. As the mineral known as hematite, Fe2O3 is the main source of iron for the

Lead (Pb) - Chemical properties, Health and …

Lead pipes bearing the insignia of Roman emperors, used as drains from the baths, are still in service. Alloys include pewter and solder. Tetraethyl lead (PbEt 4) is still used in some grades of petrol (gasoline) but is being phased out on environmental grounds. Lead is a major constituent of the lead-acid battery used extensively in car batteries.

Anthracene - Wikipedia

2019-5-11 · Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C 14 H 10, consisting of three fused benzene rings. It is a component of coal tar. Anthracene is used in the production of the red dye alizarin and other dyes. Anthracene is colorless but exhibits a blue (400–500 nm peak) fluorescence under ultraviolet radiation.

However, the [110] oriented SiCNWs could be interesting for appliions in microelectronics due to its peculiar symmetry which is similar to a nanotube. This work studies the effects of hydrogen and Oxygen in the electronic band gap of Silicon Carbide Nanowires (SiCNW) grown in [110] direction by means of Density Functional Theory.
