Road crews pit chemistry against ice
Seattle Post Intelligencer
It’s clear that applying pressure to ice makes it slippery the UW scientist said because the increased pressure lowers the melting point and creates a water layer. But he said this doesn’t explain why skis which distribute and reduce the weight pressure of a skier also seems to make snow or ice more slippery. ne way you can get rid of ice black or white is to fight its weird chemistry with more weird chemistry. That’s what state Department of Transportation road crews are doing right now. They are experimenting with a novel de-icing concoction made from Darigold’s cheese-making wastewater some “de-sugared” molasses and calcium chloride. “It’s been really successful” said Melanie Coon a spokeswoman for the Transportation Department. Nearly 20 percent of the state agency’s budget goes to winter snow and ice control she said and much of that money used to go for buying expensive anti-icing chemicals.

Subscriptions for national and foreign scientific magazines cost a considerable amount of money. Given the choice between paying the salaries or paying for the subscriptions to these scientific publications employees often favored the subscriptions in the name of science. The Institute of Petroleum Chemistry of Russian Academy of Science had 400 employees prior to “perestroika. ” They had a design bureau laboratory facilities and a manufacturer of trial samples. Afterwards there was hardly anything left of these processes and the number of scientific research specialists fell by 30 percent. The chemical industry received a serious blow as institutes focusing on development and research in the areas of petroleum production and processing basically ceased to exist. For instance there used to be cellulose ester production in Russia but not anymore as the only plant has been shut down completely.
