Sepiolite--an inexpensive, resourceful, fibrous yet inoffensive mineral--made DNA transformation rapid, simple and efficient but the mechanism for DNA transformation was still unclear. Through RNA competition test, we proposed the different transforming mechanisms from the previous report. Meanwhile, we optimized the

We have investigated the effect of mesoscopic fillers on the polymerization induced viscoelastic phase separation of thermoplastic modified thermosets at near- and off-critical concentrations using optical microscopy, time-resolved light scattering, dynamic mechanical analyses, and rheological instrument. Mesoscopic fillers including sepiolite
