| Some materials commonly used as unreactive anodes are platinum and graphite. |
|
| Once the active fluorine is chemically bound the resulting molecule is generally stable and unreactive. |
|
| Foodstuffs that are oxidized by molecular oxygen during respiration are quite unreactive with oxygen before ingestion. |
|
| At least 1 2 percent of DOC in surface waters occurs as lipids and 20 25 percent as relatively unreactive humic substances. |
|
| They are either reduced by glutathione peroxidases to unreactive fatty acid alcohols or they react with metals to produce epoxides, aldehydes, etc. |
|
| Some unreactive metals react only very slowly, such as copper and lead. |
|
| Nonmetals with eight valence electrons are chemically unreactive. |
|
| Cooling molten silica below the melting point results in fused silica, a rigid, transparent substance, chemically unreactive to the vast majority of substances. |
|
| The most dense gas known, radon is colorless and chemically unreactive. |
|
| An atom with this stable set of electrons is a very unreactive species. |
|
| Napoleon III had the money to try using aluminium which, although mostly unreactive because of a protective oxide layer, discolours easily. |
|
| Both SO4 and NO3 are largely unreactive in the mineral soils and therefore play a dominant role in controlling cation mobility. |
|
| Thus, a relatively unreactive particle could become highly combustible when it is encountered at nanometric dimensions. |
|
| It was comatose and unreactive, lying unmoving and inert, and had purplish skin. |
|
| The gas used by BERGER in this type of device is the nitrogen, this unreactive gas avoids any toxic risk. |
|
| Sodium sulfate is very stable, being unreactive toward most oxidizing or reducing agents at normal temperatures. |
|
| Studies are also conducted on the eventual transformation of relatively unreactive chemicals, such as polychlorinated biphenyls and some pesticides. |
|
| Thermoplastic polyesters are the type of polyesters in which the polyester backbones are saturated and hence unreactive. |
|
| On a relative scale, Di-t-butyl peroxide is a relatively unreactive material while benzoyl peroxide is quite reactive. |
|
| Although global emissions are largely of the unreactive form, the sheer volume and increasing proportion of the global mercury balance warrants attention. |
|
|
|
| This may indicate that lignin-modifying enzymes in vivo are not able to depolymerise PSS, and perhaps also do not efficiently decompose other unreactive synthetic polymers. |
|
| The halons are unreactive in the lower atmosphere, giving them time to float up to the stratosphere, where they release their ozone-destroying bromine. |
