The researchers say the carbon-iron-cobalt catalyst completed the conversion of hydrogen and oxygen into water, rather than producing large amounts of hydrogen peroxide.

研究者称碳铁钴复合催化剂能完全将氢气与氧气转化成为水，而不是产生大量双氧水的副产物。

Improve the ratio of carbon-iron can increase the metallization of the finished pellets, however, the lower carbon-iron ratio (0.32) still can get a relatively high rate of metallization.

提高碳铁比可以提高成品球的金属化率，但微波还原过程中较低的碳铁比(0.32)仍可以获得相对较高的金属化率。

When iron became highly oxidized, so did diamonds; that is, they vaporized into carbon dioxide.

当铁被高度氧化时，钻石也被高度氧化；也就是说，它们蒸发成二氧化碳。

This is because the atmosphere does not have an iron grip on the carbon-dioxide level in surface waters.

The iron-and-carbon-based ink used in one of the oldest Hebrew commentaries on the Old Testament is an example of this.
