Abstract The surface of epoxy composite material working in DC electric field for a long time is easy to accumulate charge and cause flashover, which seriously reduces its insulation level poses threat the safe operation electrical equipment. In this study, SiO x films were deposited on nano-SiO 2 /ER nanoparticles by atmospheric pressure dielectric barrier discharge plasma vapor deposition tec...

The fabrication and surface modification of a porous cell scaffold are very important in tissue engineering. Of most concern are high-density cell seeding, nutrient and oxygen supply, and cell affinity. In the present study, poly(L-lactic acid) and poly(L-lactic-co-glycolic acid) (70/30) cell scaffolds with different pore structures were fabricated. An improved method based on Archimedes' Princ...
