...first textile made from a vegetable protein.* Mr. Ford was presented with a tasteful necktie one-third of which was woven from the soybean fabric, the rest of silk and wool. Protein is extracted from soybean meal in saline solution, then mixed with other chemicals to make a viscous liquid, which is squirted into hair-sized filaments. The spun thread has a pleasant feel, fairly good tensile strength, takes dyes readily. Its intended use: automobile upholstery...
...virus molecule's diameter is just under the visibility limit of the most powerful microscopes. Dr. Langmuir made a molecule that anyone could see with the naked eye by adding acetic acid to a dilute solution of sodium silicate. After a while the solution became viscous and turned into a jelly. The molecules had combined to form bigger ones, the process speeding along in geometrical ratio until one super-giant molecule filled the entire container...
...underlying mechanism. After radioactivity was discovered, Joly of England and others hit on the concept of thermal pulsation: radioactivity in the solid, or nearly solid, sub-crust of Earth causes heat to be stored there until the sub-crust melts. The continental masses sink deeper into this dense, viscous pool, which in turn moves sideways, bulging and rifting ocean floors, allowing heat to escape. Then the cycle begins again. Wegener of Germany proposed that two great continents, Gondwanaland in the Southern Hemisphere and Eurasia in the Northern, cracked and sundered, slid like cakes of ice over the hot sub-crustal...
Heavy water is only 10% heavier than ordinary water, slightly more viscous, boils at 214½° F. instead of 212°. Guppy fish, tadpoles and flatworms die in it, but mice fed with it seem to get tipsy. It has been found in slightly higher than normal concentration (one part in 4,500) in the Dead Sea, the Great Salt Lake, the sap and wood of willow trees, borax deposits. The hydrogen of honey, coal benzene and kerosene was found comparatively rich in D. But in the Sun's atmosphere only one atom...
...making rayon by the viscose process, cellulose is first reduced to a viscous mass. For Sniafiocco the stuff is passed through a fine-mesh screen; the threads are coagulated, cut, finished. They are then ready for the spinner. Snia Viscosa loudly protests against labeling Sniafiocco a synthetic or substitute cotton. It is superior to cotton, say the Italians, in that the staple length of its fibre is precisely even and can be given any length wanted by the spinner, and that it is free of dirt and leaves which contaminate raw cotton. Thus although Sniafiocco fibre costs more than cotton...
