- Abstract:
- ... The self-assembly of platy clay particles is influenced by anisotropic surface charging properties of the particles. The Stern potentials of particle surfaces are controlled by solution pH. Consequently, the energy-favorable particle association varies with pH, leading to different self-assembly structures. Therefore, it should be possible to form desired nanostructure of final clay product throug ...

- Abstract:
- ... A variety of oil sorbents with good hydrophobicity and oil-absorption capacity have been reported. However, their practical application is severely hindered by complex preparation process, high application cost and non-biodegradability. Here, Calotropis gigantea fiber (CGF) from plant fibers and polylactic acid (PLA) from renewable resources were utilized to construct a biodegradable foam-like oil ...
