Aerogel, a futuristic-sounding lightweight solid sometimes referred to as "frozen smoke," could one day mop up oil spills like one this week in the Irish Sea and filter wastewater because of its super-absorbent, sponge-like qualities.
Nanogel, a branded aerogel made of modified, water-repellent silica, soaked up oil faster and in greater quantities than other materials that are typically used in wastewater filtration, according to a study in the latest issue of the biweekly journal Industrial & Engineering Chemistry Research. Boston-based Cabot Corp., which makes Nanogel, helped pay for the research and supplied the product.

Is your neighborhood using? Researchers from Oregon State University and the University of Washington have devised technology that analyzes what’s been flushed down the toilet to measure how many speed freaks and coke heads you’ve got living down the street.
A report published in the Dec. 15 edition of the American Chemical Society journal Environmental Science & Technology describes a new test that uses standard chemical analytical methods to look at what stuff makes its way through the municipal sewer systems to wastewater treatment plants. There, the test can measure levels of drugs including illegal substances like crystal methamphetamine. Unlike previous methods, the technique does not require expensive and time-consuming sample preparation, making it a practical for comparing drug use in different regions.
