Last week Radio Corp. of America demonstrated a sub-thimble-size radioactive battery that is somewhat more efficient. A film of Strontium 90 is spread on a wafer of silicon. When its beta particles shoot into the silicon, each of them releases 200,000 fresh electrons, which are collected as an electric current by a spot of silicon-antimony alloy...
Hopper Helper. A new freight car for bulk shipments of dry powdered commodities (feed, chemicals), which formerly had to be transported in containers, was put into production by General American Transportation Corp. The car contains bins with slanted sides lined with a porous, silicon-treated fabric. To unload the car, air is blown at low pressure under the fabric, breaking up hard-packed cargo so that it flows like water through hatches under...
...West Point chemistry class one day in 1854, Cadet James Abbot Whistler was asked to discuss silicon. He began: "Silicon is a gas." "That will do, Mr. Whistler," said the professor-and shortly thereafter Cadet Whistler was handed his discharge papers. In later years, when he had made himself one of the finest painters of his day, he liked to say: "If silicon had been a gas, I would have been a general...
Rochow received the Bakeland Medal for outstanding work on compounds of silicon. A research chemist for general Electric for 13 years, Rochow was made an associate professor...
Professor Rochow, an industrial chemist before he joined the Harvard faculty in 1948, is an international authority on silicon compounds. This year he will investigate ways of preparing organic silicon compounds which are the base of carborundum, next to diamonds the hardest material known, and in another form free flowing oils which stay find at low temperatures...
