Late Quaternary lake filling and drying in northern Australia's largest freshwater lake
Journal of Quaternary Science, EarlyView.ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...

Micellar and Solubilization Properties of Biological Surfactant Surfactin
Journal of Surfactants and Detergents, EarlyView.ABSTRACT We studied aqueous solutions of surfactin in the concentration range of 0.001–200 g/L using NMR diffusometry, tensometry and optical microscopy methods. According to tensometry data, the system forms monolayers of surfactant molecules at the water‐air phase boundary at C = 0.02 g/L.
