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...

...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 was not announced, but it has far greater durability, and will make possible explosives and fertilizers both more effective and much cheaper than any now existing...

...divert public interest from helium. Asserting that electrical sparks twelve to eighteen inches in length were seen on the helium-filled Shenandoah on the night of its great adventure (TIME, Jan. 28) and that these sparks would have set it on fire, had it been filled with hydrogen, Dr. Howe-through the pages of his journal-demanded to know why this important fact has been overlooked in official and press discussions. "What is back of this obvious effort to have the American people forget helium...

...Alaska- where mooring masts and other equipment have to be carefully prepared- but in a five-day non-stop flight of 6,000 miles from Lakehurst straight to the Pole and back. And this at 24 hours' notice. But it would be possible only with the lighter hydrogen gas. "With hydrogen, we could make the trip to the Pole and back easily and safely. With helium it is necessary to have mooring masts, where the ship can be tied up because she could not carry enough fuel for the round trip...

...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...
