The metal-non-metal transition in VO2: X-ray photoemission and resistivity measurements The semiconductor-metal transition in VO2 has been investigated by means of XPS measurements. The band gap in the semiconducting region is found to be temperature-dependent with a room temperature value of Eg=...

Mixtures of metal/nonmetal nitrates with alkyl esters may explode because of the formation of alkyl nitrates; mixtures of nitrate with phosphorus, tin (II) chloride or other reducing agents may react explosively [Bretherick 1979. p. 108-109]. An explosion of guanidine nitrate demolished an auto...
Does silver metal possess electrical conductivity? Explain. Describe the bonding in metals and discuss how this explains high electrical conductivity. Explain why copper possesses a high electrical conductivity. Is silicon a conductor or semiconductor? Explain. A nonmetal is usu...
When an element whose nucleus has 115 protons is synthesized, which type of element will it be: a metal, a nonmetal, or a metalloid?What are the 7 mystery elements on the periodic table?Which elements in the periodic table constitute the alkali metals?
Synthetic of inorganic nonmetal/metal oxide White powder 3-25u Can mix glaze/pigments,or singlely Screen printing/spary/brush(mix liquid medium) On glass/ceramic surface ,or mix in body to melt Firing up to the working temperature,to low down the firi...
In similar way, lead forms a series of relatively insoluble compounds, many of which are strongly adherent to the metal surface. Thus, in conditions where a stable continuous film can form, further reaction is often prevented or greatly reduced. The generally good corrosion resistance of lead res...

1. Introduction As a part of investigations of the metal-nonmetal transition using metal-gas films, lead-argon films were prepared. Besides the investigation of the metal-nonmetal transition [1], the effect of argon content on the superconducting transition temper-ature was studied. The ...
Due to their immutable nature, metals are a group of pollutants of much concern. As a result of human activities such as mining and smelting of metallifero
