With the reaction of PAS, the change of chromium gluconate on hepatic glucogen of diabetic mice induced by alloxan was observed.

Microdetermination of Chromium in Ultrabasic Rock and Steel;

Elinvar is a trademark for a kind of nickel-chromium steel used for watch springs because its elasticity is constant over a wide range of temperatures.

In order to strengthen its antifriction property, the material nature of the boards chooses a special formula of high molybdenum, high chromium and nickelic.

J.K. Dennis, T.E. Such, 1993, Nickel and chromium plating, Woodhead Publishing Ltd, England.

The preparation methods of dimethylamine hydrochloride/chromium trioxide oxidation reagent and the selective oxidation reaction of cyclohexenol to cyclohexenone with this catalyst are studied.

If total chromium is to be determined, it is necessary to oxidize the Cr(Ⅲ) to Cr(Ⅵ) by potassium permanganate before reacting with diphenylcarbazide.

At present, trivalent chromium electroplating process has became one of the mostimportant techniques to taking place of the seriously pollutional hexvalent chromiumelectroplating process.

This paper has introduced the green-protection zincum-chromium coat, i n ianther word, it is "DACROMET" coat, it is one kind of liquid that confected from zincum flake alumimium flake chromate flake.

Pyridine can react with halogens,nitronium fluoroborate, sulfur trioxide, boranes and chromium trioxide to form some useful organic reagents which are introduced briefly in the paper.

Some common troubles such as poor throwing power,burnt deposit on rim,dull gray coating,piebaldism,blue film,hazy deposit,spongy surface and roughness in decorative chromium plating were summarized.

Electrotechnical products - Determination of levels of six regulated substances (lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers

One thing which is strange is the total chromium contained in the paddy plants.

These metals included zinc, chromium, nickel and cadmium.

" Stainless steel" is a metal that has another metal mixed with it called " chromium" (chromium).

Unfortunately, some of these contain cancer-causing cadmium, lead, chromium, and mercury.

The e-liquid or the aerosol can also contain metallic particles like chromium, cadmium and lead.

He was huddled in the corner under the two shining faucets, and water dripped slowly on his chest, from the chromium showerhead.

Some sneaker tops are made from natural sources like leather, but tanning this material relies on chromium; a carcinogenic chemical that can damage freshwater ecosystems.

The fog had cleared off outside and the stars were as bright as artificial stars of chromium on a sky of black velvet.

Firstly, too much turbidity, trace organic compounds, or high-density heavy metals like arsenic, chromium, or lead, mean that the water is unsuitable for consumption.

The shower curtain was green and white oiled silk and it hung on shiny chromium rings and it was drawn across the shower opening.
