concrete | Definition, Composition, Uses, & Facts

Concrete that has been hardened onto iedded metal (usually steel) is called reinforced concrete, or ferroconcrete.Its invention is usually attributed to Joseph Monier, a Parisian gardener who made garden pots and tubs of concrete reinforced with iron mesh; he received a patent in 1867.The reinforcing steel, which may take the form of rods, bars, or mesh, contributes tensile strength.

Isotope analysis - Wikipedia

2019-4-13 · Isotope analysis can be used by forensic investigators to determine whether two or more samples of explosives are of a common origin. Most high explosives contain carbon, hydrogen, nitrogen and oxygen atoms and thus comparing their relative abundances of isotopes can reveal the existence of a common origin.

Electrode potentials [SubsTech]

Standard electrode potentials are measured relatively to the standard hydrogen electrode, potential of which is defined as 0 volt: E 0 = E 0 R - E 0 (H/H 2) = E 0 R When a standard electrode potential is measured the electrode is connected to the positive terminal of the voltmeter and the standard hydrogen electrode is connected to the negative
