Versatile is the word for this online monitor
Article Abstract:
Fraunhofer Institute for Chemical Technology in Pfinztal, Germany, has designed the Aqualine analyzer, an online monitor for over 20 different volatile substances in wastewater streams. The device that consists of a polytetrafluorothylene membrane filters and pumps water samples, which are cooled by at approximately 10 degrees celsius. The water samples are chilled by Peltier elements to lessen permeation of water vapor. The technology, with an accuracy rate of roughly 1%, has sensitivity ranging from 10 micro gram per liter for chlorinated hydrocarbons to about 10 mg per liter for ammonia.

A renewed boost for ethanol
Article Abstract:
The use of biotechnology has provided a way for ethanol to effectively compete with other fuels after being severely affected by the high prices of corn and low prices for oil. Genetically engineered bacteria are used to produce ethanol from biomass. One example of this process is the facility, to be owned and operated by BC International. Feedstocks for the plant will be bagasse, sugar cane waste from sugar refining, and rice hulls.

Reshaping clay
Article Abstract:
Kaolin and other clays are facing increasing competition from materials such as calcium carbonate. Still, kaolin is expected to benefit from the growing demand for functional fillers and high-performance coatings. In addition, smectite clays such as vermiculite, bentonite and montmorillonite will find increasing use as plastic fillers with as nano- scale clay particles were found to boost key performance parameters of plastics.
