Palmitic Acid Sophorolipid Biosurfactant: From Self-Assembled Fibrillar Network (SAFiN) To Hydrogels with Fast Recovery [PDF]
, 2021 Nanofibers are an interesting phase into which amphiphilic molecules can self-assemble. Described for a large number of synthetic lipids, they were seldom reported for natural lipids like microbial amphiphiles, known as biosurfactants. In this work, we show that the palmitic acid congener of sophorolipids (SLC16:0), one of the most studied families of ...

High-Efficiency Separation of Mg2+/Sr2+ through a NF Membrane under Electric Field
Membranes, 2021 The efficient separation of Sr2+/Mg2+ through nanofiltration (NF) technology is a great challenge because Sr2+ and Mg2+ ions are congeners with the same valence and chemical properties.
