In a recent report, Xundu Feng and colleagues at the interdisciplinary departments of chemical and environmental engineering, biomolecular engineering, chemistry and the center for advanced low-dimension materials in the U.S., France, Japan and China, proposed and demonstrated a new approach to prevent the existing challenges. In the study, they explored size-selective transport in the water-continuous medium of a nanostructured polymer template formed using a self-assembled lyotropic H1 (hexagonal cylindrical shaped) mesophase (a state of matter between liquid and solid). They optimized the mesophase composition to facilitate high-fidelity retention of the H1 structure on photoinduced crosslinking. /news/2019-08-self-assembled-membrane-water-continuous-pathways-precise.html Polymers Materials Science Wed, 21 Aug 2019 09:30:05 EDT news485504419 The world is a big place, but it's gotten smaller with the advent of technologies that put people from across the globe in the palm of one's hand.
