Nerve agents and chemicals include, but are not limited to, VX nerve gas, Tabun gas, Sarin, Soman, and the marker chemicals zinc cadmium sulfide, and QNB.

Large zinc – air batteries, with capacities up to 2, 000 ampere – hours per cell, are used to power navigation instruments and marker lights, oceanographic experiments, and railway signals.

In February 1801, Oersted did manage to experiment with physical apparatus and reported experiments made with a voltaic battery of 600 plates of zinc and silver and of later experiments with a battery of 60 plates of zinc and lead.

Examples of substitutional alloys include bronze and brass, in which some of the copper atoms are substituted with either tin or zinc atoms.

In the Middle East, people began alloying copper with zinc to form brass.

The zinc, which is higher than both copper and hydrogen in the electrochemical series, reacts with the negatively charged sulfate ( SO < sub > 4 </ sub >< sup > 2 −</ sup >).

This process coats iron structures ( such as fencing ) with a coating of zinc metal.

Brass Dice | die, along with zinc and copper samples.

Brass is an alloy of copper and zinc ; the proportions of zinc and copper can be varied to create a range of brasses with varying properties.

* Alpha brasses with less than 35 % zinc, are malleable, can be worked cold, and are used in pressing, forging, or similar applications.

* Beta brasses, with 45 – 50 % zinc content, can only be worked hot, and are harder, stronger, and suitable for casting.

* Cartridge brass is a 30 % zinc brass with good cold working properties.

* Low brass is a copper-zinc alloy containing 20 % zinc with a light golden color and excellent ductility ; it is used for flexible metal hoses and metal bellows.

The term may also refer to certain types of nickel silver alloys as well as Cu-Zn-Sn alloys with high proportions ( typically 40 %+) of tin and / or zinc, as well as predominantly zinc casting alloys with copper additive.

Although forms of brass have been in use since prehistory, its true nature as a copper-zinc alloy was not understood until the post medieval period because the zinc vapor which reacted with copper to make brass was not recognised as a metal.

Brass was produced by the cementation process where copper and zinc ore are heated together until zinc vapor is produced which reacts with the copper.

They show no signs of slag or metal prills suggesting that zinc minerals were heated to produce zinc vapor which reacted with metallic copper in a solid state reaction.

Such payments shall be made to small domestic producers of zinc as long as the market price for prime western zinc at East Saint Louis, Illinois, as determined by the Secretary, is below 14-1/2 cents per pound, and such payments shall be 55 per centum of the difference between 14-1/2 cents per pound and the average market price for the month in which the sale occurred as determined by the Secretary.

As long as the zinc remains intact, the iron is protected from the effects of corrosion.

Other metals long known to form binary alloys with zinc are aluminium, antimony, bismuth, gold, iron, lead, mercury, silver, tin, magnesium, cobalt, nickel, tellurium and sodium.

Green: Combination of zinc sulfide with copper, the P31 phosphor or ZnS: Cu, provides green light peaking at 531 nm, with long glow.

Mineral makeup is noncomedogenic ( as long as it doesn't contain talc ), and it offers a mild amount of sun protection ( because of the titanium dioxide and zinc oxide ).

The 1954 movie Salt of the Earth, directed by Herbert J. Biberman, a member of the blacklisted Hollywood Ten, portrays a year-and-a-half long strike by New Mexico zinc miners who belonged to Mine, Mill ; many of the actors were rank-and-file members of that union.

Lightning arresters built for power substation use are impressive devices, consisting of a porcelain tube several feet long and several inches in diameter, typically filled with disks of zinc oxide.

Here we erected a pole, high, on the top of which was a cylindrical cap of zinc, long and diameter.

Internal construction is different from other concertinas in that the action more closely resembles that of an accordion, and that the reeds are of steel ( rather than brass ) and are often fixed in groups of twenty or more to long zinc or aluminum plates, rather than to individual frames.

They are rich in zinc and protein — both supportive for the immune system and long bone growth in reversing stunted height, while protein also contributes to muscle development.

The Apollo service modules used as crew ferries to the Skylab space station were powered by three silver – zinc batteries between undocking and SM jettison as the hydrogen and oxygen tanks could not store fuel cell reactants through the long stays at the station.

Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, That the Secretary of the Interior is hereby authorized and directed to establish and maintain a program of stabilization payments to small domestic producers of lead and zinc ores and concentrates in order to stabilize the mining of lead and zinc by small domestic producers on public, Indian, and other lands as provided in this Act.

The Belgians were interested primarily in the economic development of the Congo, which is rich in copper, tin, cobalt, manganese, zinc, and uranium, and cotton and palm oil.

Brass is an alloy made from copper and zinc.

Also, the power of the cell diminishes over time because the hydrogen gas is not released, accumulating instead on the surface of the zinc electrode and forming a barrier between the metal and the electrolyte solution.

The resultant current ensures that the zinc coating is sacrificed but that the base iron does not corrode.

Owing to the complete absence of mountain building and glaciation since the Permian ( in many areas since the Cambrian ) ages, the outback is extremely rich in iron, aluminium, manganese and uranium ores, and also contains major deposits of gold, nickel, iron, lead and zinc ores.

Selenium and zinc are commonly referred to as antioxidant nutrients, but these chemical elements have no antioxidant action themselves and are instead required for the activity of some antioxidant enzymes, as is discussed below.

* Prince's metal or Prince Rupert's metal is a type of alpha brass containing 75 % copper and 25 % zinc.

* Alpha-beta brass ( Muntz metal ), also called duplex brass, is 35 – 45 % zinc and is suited for hot working.

* Common brass, or rivet brass, is a 37 % zinc brass, cheap and standard for cold working.

An alloy of 95 % copper and 5 % zinc, gilding metal is typically used for ammunition bullet " jackets ", e. g. full metal jacket bullets.

* High brass contains 65 % copper and 35 % zinc, has a high tensile strength and is used for springs, screws, and rivets.

* Muntz metal is about 60 % copper, 40 % zinc and a trace of iron, used as a lining on boats.

* Naval brass, similar to admiralty brass, is 40 % zinc and 1 % tin.
