oxidize

It’s full of metallic iron, rather than the oxidized type of iron that plants can use.

The researchers found that zapping the material with electricity to oxidize the surface will trigger it to change its surface tension and thus, the shape of the liquid metal.

Beta cells have low levels of antioxidants and are susceptible to attack by metabolic and dietary oxidized free radicals and AGEs.

As the groundwater seeped into the lake, the iron became oxidized and precipitated out as goethite particles.

The methane produced in the soil is being transported from the roots all the way up rather than being oxidized in the soil.

Of course, this causes the nail clippers to oxidize and the water turns rusty, but it boils.

They oxidize organic materials, changing them to compounds that can be absorbed by plants and used in building protoplasm.

My purpose in slackening my heat as soon as the pig-iron was melted was to oxidize the phosphorus and sulphur ahead of the carbon.

The purpose now is to oxidize the carbon, too, without reducing the phosphorus and sulphur and causing them to return to the iron.

Just as alcohol vaporizes at a lower heat than water, so sulphur and phosphorus oxidize at a lower heat than carbon.

Chromic and nitric acids oxidize it to oxalic acid and carbon dioxide.
