Lavoisier also found that the weight of the gas released by heating mercury oxide was identical to the weight lost by the mercury oxide, and that when other elements react with oxygen their weight gain is identical to the weight lost from the air. This enabled Lavoisier to state a new funda...

On my Noble Rack page I have all the pictures collected, along with pictures of arcs I made in my other collection of noble gas flasks. This oxygen tube is not installed in the table, because it's so dim you couldn't really see it, and it's said to not last very long. So I ...
0.264 nm, inset of Fig. 1d, Supplementary Fig. 9)20,31. Elemental mapping images of SGO (Fig. 1e) prove that the homogeneous distribution of all elements, including Sn, Ge and O, in the material. Energy dispersive X-ray spectroscopy (EDS) indicates the atomic ratio of Ge: Sn in...
19c). Intermetallic libraries of small nanoparticles composed of 46 combinations of platinum with 16 other metal elements were synthesized and used to study the dependence of electrocatalytic oxygen reduction reactivity on alloy composition and platinum skin strain. The intermetallic libraries have high...
our understanding of the composition and activity of microbial communities inhabiting these hidden aquatic ecosystems is still patchy, often developed from samples of a few select wells or a single aquifer. In particular, the geochemical and ecological processes that shape groundwater microbial communitie...
The energy dispersive spectroscopy (EDS) mapping revealed the uniform distribution of O, Fe, Ni, and Mo elements in MoNiFe (oxy)hydroxide (Fig. 1h). MoNiFe-x% (oxy)hydroxide samples with other Fe contents exhibited very similar structure characteristics (Supplementary Fig. 6). All the MoN...

Lipid oxidation and formation of oxygen radicals are important elements of arterial plaque formation and atherosclerosis, and are involved in the pathophysiology of cardiovascular disease. Several potential mechanisms have been suggested to play a potential role in the antiatherogenic and cardioprotective eff...
Uses:Oxygen was the atomic weight standard of comparison for the other elements until 1961 when the International Union of Pure and Applied Chemistry adopted carbon 12 as the new basis. It is the third mostabundant elementfound in the sun and the earth, and it plays a part in the carbon-n...
