Making polyurethane waste degradable gives its components a second life

27-Aug-2019 - Polyurethane waste is piling up in landfills, but scientists have a possible solution: They have developed a method to make polyurethane degradable. Once the original product's useful life is over, the polymer can easily be dissolved into ingredients to make new products such as superglue. These ...

Ozone recovery may be delayed by unregulated chemicals

29-Jun-2017 - Recent increases in an unregulated ozone-depleting substance, could delay recovery of Antarctic ozone levels by 5-30 years, depending on emissions scenarios. The findings suggest that a previously ignored chemical called dichloromethane may now be contributing to ozone depletion and should be ...

The chlorinated solvents market went down primarily in the second half of 2008 under the grip of the economic ...

Chlorinated solvents industry regrets most widely used solvent in paint stripping will be partly banned

20-Jan-2009 - The European chlorinated solvent industry, represented by ECSA, regrets the EU Parliament backs the ban on Dichloromethane in paint stripping. This ban will not necessarily enhance the safer use of paint strippers because the alternative substances have not yet been submitted to an adequate risk ...

Chlorinated solvents market down again after one year of stabilisation

16-Jun-2008 - After one year of stabilisation in 2006, European sales of chlorinated solvents were down again in 2007. The decline of trichloroethylene (TRI) sales continued after the more stringent carcinogenicity classification for trichloroethylene introduced in 2002. The ECSA Member companies and the ...

Rings Made of Little Rods

Water droplets as templates: gold nanorods self-assemble into rings

14-Mar-2007 - Rod-shaped nanocrystals normally arrange themselves parallel to each other. Researchers at Rice University in Houston, Texas now report in the journal Angewandte Chemie completely unexpected behavior of nano-objects: the spontaneous self-assembly of polymer-coated metallic nanorods into ...
