...point of printing its annual report in newspapers rather than sending copies to almost 475,000 shareholders. The company also stepped up and centralized its research, which has pioneered in weed killers, growth stimulants for plants, antimalarial drugs, improved aviation gas and a cheaper method of producing ammonia...
...Napoleon brought with him to establish a cultural institute in Alexandria. The assembled scientists interspersed papers like "Observations on the Wing of the Ostrich'' and "Analysis of the Slime of the Nile" with studies on capillary attraction, the treatment of smallpox and bubonic plague, the formation of ammonia and the nature of light...
...capsule is far from a practical factory, but Aerojet is now building a pilot plant that will circulate a mixture of ammonia and uranium oxide through a nuclear reactor. If Aerojet calculations are correct, the plant should produce hydrazine, which now costs $1.50-$2 per lb., for as little...
Aerojet scientists mixed liquid ammonia (NH3) with powdered uranium oxide, sealed the mixture in a capsule and stuck the capsule in a nuclear reactor at Livermore Laboratory. When neutrons from the reactor hit uranium atoms in the capsule, they caused the atoms to fission, or split. The atomic fragments shot apart with enormous energy (200 million electron volts per fission), splintering ammonia molecules and knocking them in every direction. The fragments recombined at once. Some formed gaseous hydrogen (H2) or nitrogen (N2). But about half the ammonia that reacted formed the much-desired hydrazine (N2H4...
Students of ancient life believe that billions of years ago the newly formed earth was covered by an atmosphere that had no free oxygen in it. Instead it had methane, ammonia, carbon dioxide and other gases that cannot be breathed by modern animals. Lightning flashes, so the theory goes, forced these gases to form complicated chemicals that dissolved in sea water. There the chemicals reacted with each other and the water, forming bigger and bigger molecules. After millions or billions of years of this process, a single molecule-perhaps a nucleic acid-was formed that had the ability to grow...
