...from the apparatus, the sensitive little birds would collapse in time for the men to take action. Pacific, round-faced, gum-chewing Dr. Urey and his associates were not interested in poison, they were simply using the dangerous gases to make a harmless but scientifically important substance called "heavy carbon." An atom of heavy carbon weighs 13 units as compared with ordinary carbon's twelve...
...Sept. 20, 1937). Nitrogen is present in all proteins. Heavy nitrogen atoms can be distinguished from the common kind by mass spectrographic means, but in protein reactions they run along with their lighter fellows, and so serve as "tagged atoms" or chemical spies to show where the nitrogen goes. Carbon is a vital ingredient of all living substance, and by using heavy carbon atoms as tracers Dr. Urey expects physiologists to find out much more about carbon metabolism than is now known...
...Union Carbide & Carbon's directors approved the purchase of Bakelite Corp. (for some $15,375,000 worth of Carbide stock), thus adding a major plastics division to its big chemical business...
...butane molecule contains four atoms of carbon, ten of hydrogen. In the Egloff process, two atoms of hydrogen are first ripped out of the butane molecule at a temperature of 1,000° F. with the help of a catalyst (chemical activator). Then two more hydrogen atoms are torn out by repeating the same process. The molecule thus stripped is called butadiene gas. Another catalyst, and mild heat, then link up the molecule in long chains-and the tough, solid substance so formed is butadiene rubber...
...carbon copy, not a sequel, yet not entirely a fresh and uninfluenced cinema, Daughters Courageous has a coltish, unaffected charm, considerable wit, an ill-concealed admiration for its two picaresque but impossible male mainstays. Not calculated to stir up too much emotion, one scene in it will nevertheless bring goose-pimples to many a tough-bearded male. The scene: the girls, barbering their stepfather-elect, shaving downwards over his Adam's apple...
