...Professor Vigard, of the University of Christiania, Norway, claims he has discovered another and better reason. Just outside the earth's atmosphere, he says, is a wall of crystalline particles of nitrogen. This is what makes the sky blue. It also explains, he thinks, why radio waves follow the contour of the earth, instead of flying off from it at a tangent. This would seem to indicate that radio communication with other planets will always be impossible...
Production of nitrogen compounds from the air has been made far more economical and efficient by an important chemical discovery, according to a statement made yesterday by Professor Arthur B. Lamb, of the Department of Chemistry of Harvard University...
...process owes its success to the developed of a new contact material, or catalyst, as it is called, which causes the nitrogen in the air to combine with other substances, especially hydrogen, with greater case and efficiency than has hitherto been the case. Where the catalysts used in other processes will produce 7 or 8 percent of ammonia, this new compound will yield 14 percent, and it has been run continuously for six months without deterioration...
Professor Lamb was director of the Fixed Nitrogen Research Laboratory at Washington, where the catalyst was developed, during and after...
...earth, these become harmless through microbic activity. These upper layers of the soil are the ancestral home of the bacteria, where they are concentrated most thickly. Germs which break down organic matter in the soil are frequently attached to the roots of legumes (beans, peas, clover), and act as " nitrogen-fixers" for the vegetable kingdom...
