Where sapphire gets its blue tint mainly from iron, rubies get their pink to blood-red hue from chromium. So [NightHawkInLight]’s recipe starts with aluminum oxide grit-blasting powder and ...

That chromium does oxidize by the way, just like the iron does, but instead of looking ugly and unsafe, that little layer of chromium oxide -- just a few nanometers thick, in some cases -- keeps that ...

Scientists are urgently searching for clean fuel sources—such as hydrogen—to aid in the move toward carbon neutrality. A ...

but also underwater — to create a "passive layer" of chromium oxide (Cr2O3) on the metal's surface. This layer prevents the oxygen from reaching iron in the steel to create rust, Collins explained.

[Frankie]’s explanation of the chemistry is that the surface layer of the stainless is a transparent chromium oxide. With the heat of the laser, the calcium and chromium swap dance partners.

This soft, natural matte foundation is made with skin-loving ingredients like Hyaluronic Acid, Vitamin E, and Moringa Seed ...

Many different metals have been used for the catalysis, and good water-splitting performances have been achieved with a light-absorbing chromium oxide system as the charge-transfer moiety coupled ...

The material the Nebraska team is studying—chromium oxide with a dash of boron—could help herald the emergence of digital memory and processors that consume far less power, while potentially ...

Chromium is a metal in group VIB of the periodic table with atomic number 24, an atomic weight of 51.996, and a density of 7.19. It has a melting temperature of 1875 C. The electronic configuration ...

A browse through images of chromium compounds on Wikipedia shows a whole spectrum of colours: dark red chromium(VI) oxide, orange-red lead chromate, bright yellow sodium chromate, brilliant chrome ...

A group of researchers from Tohoku University, Tokyo University of Science, and Mitsubishi Materials Corporation have made a ...

Researchers have developed a novel method using facet-selective, ultrafine cocatalysts to efficiently split water to create hydrogen -- a clean source of fuel.
