Super absorbent polymer may be used on oil spills

RATE THIS! +6

As the Deepwater Horizon disaster showed us, we need to develop better ways of cleaning up oil spills. While many ideas have been put forth, scientists from Pennsylvania State University have come up with something that particularly shows promise – a polymer that soaks up 40 times its weight in oil.

 

When applied to a water body where an oil spill has occurred, the Polyolefin Oil Superabsorbent Polymer reportedly transforms the floating crude oil into “a soft, solid oil-containing gel.” The scientists claim that one pound (453 grams) of the polymer can soak up around five gallons (19 liters) of oil, without absorbing any water. The gel can subsequently be collected, transported, and refined to recover the trapped oil.

 

More traditional oil-absorbing materials such as corn cobs and straw reportedly only absorb about five times their weight in oil, plus they also absorb water.

In modern times the old ways of opera madly emotional sopranos and tenors bawling undying love at each other have lost their conviction. "By 1945," the authors write, "operas great undertow the expressive power inherent in the melodic arc, as performed by a human voice was demanding a faith that for many composers was beginning to look blind." They offer a melancholy recitation of the many contemporary operas that have been launched with great fanfare and then sunk without trace. The message of the book, by the end, is a gloomy one: operas glory days are over; weve lost the faith in the voice; all thats left to us is an ever-more sophisticated recycling of the great operas of the past. Thus the books title%3 Reply
