...audience startled and gasping when Professor A. B. Lamb G'03, director of the chemical laboratory, presented the chemist's viewpoint of heat at the fourth symposuim held in the Union Living Room last night. Performing experiments that ranged from simple illustrations of the effect of oxygen and nitrogen on flame to breath-taking feats that approached necromancy, Professor Lamp kept the audience in a continual flurry of excitement...
...crystalline substance, Vitamine D, which he prefers to call by the name of "bios" first used by Professor Wildiers, of the University of Louvain, Belgium, in 1900. It was extracted from a solution of autolyzed (self-digested) yeast. It is an organic chemical structure composed of 43% carbon, 25% nitrogen, 8% hydrogen and 24% not yet completely analyzed...
...complaint that things can't be run on air is thoroughly exploded. Chemists have for years been making some most important compounds out of the raw material of air. "Free" oxygen and nitrogen in the air, for instance, can be "fixed" by a gigantic electric arc into nitric oxide, from which nitric acid and nitrates (valuable fertilizers) are made...
Then in 1914 Fritz Haber, clever German necromancer, found that nitrogen gas can be captured in another way-by combining it with hydrogen to form ammonia. Instead of electricity, the Haber process makes use of an agent called a "catalyst," which is a substance that by its mere presence causes the union of two other elements. Efficient catalysts, or as Dr. E. E. Slosson calls them, the "good mixers" of chemical society, are expensive. Haber used uranium, platinum or some other rare and finely divided metal. When the nitrogen and hydrogen, after being elaborately purified, mixed in proper proportions, compressed...
Chemists of all nations have been seeking to improve the existing methods of nitrogen fixation. Last week the most important discovery since Haber's was announced from the fixed nitrogen research laboratory of the Chemical Warfare Service of the U. S. Army, at Washington, by Dr. Arthur B. Lamb, director of the laboratory, and professor of chemistry at Harvard University. A new catalyst has been found to unite the atoms of nitrogen and hydrogen into the molecule of ammonia. It yields 14% of ammonia, twice the amount given by the Haber process. The nature of the catalyst...
