A step toward ridding register receipts of BPA

Although the U.S and other countries have banned or restricted the use of bisphenol A (BPA) because of environmental and health concerns, it is still used in thermally printed receipts and labels. Now researchers report in ...

Using polymeric membranes to clean up industrial separations

There are scores of promising technologies under development that can reduce energy consumption or capture carbon in fields including biotech, computer science, nanotechnology, materials science, and more. Not all will prove ...

Coming round to stable self-assembly

Nanostructures that assemble themselves from polymer molecules could prove to be useful tools in chemistry and industry. However, it is difficult to develop structurally robust self-assembling materials because they are often ...
