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 ...

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 ...

What drives ions through polymer membranes?

Ion exchange membranes are needed in (photo)electrolyzers, fuel cells and batteries to separate ions and enable the desired processes. Polymeric membranes such as synthetically produced compounds like NAFION are particularly ...
