In more ordinary circumstances, burning of sulfur—usually not directly but as a part of fossil fuels—does anything but “cleanse all pollution”: combustion of coal and oil products, and also processing of hydrocarbons and smelting ofHAUNT 发表于 2025-3-24 01:06:56
R. Friedrich,V. K. Jirsa,H. Haken,C. Uhlin water—upon dehydration, about 45% of it, a share much higher than that of any other element, is carbon. Even in the biosphere taken as a whole, with its enormous stores of ocean water, carbon accounts for one-quarter of all atoms and shares second place with oxygen (hydrogen atoms are, obviously, most abundant).Munificent 发表于 2025-3-24 05:11:32

At the same time, in the second half of the 1960s, I was introduced by a friend, an engineer working in analytical chemistry and biochemistry, to some of the mysteries of enzymes;
