Magnetic Fe3O4@PANI@Au nanocomposites are fabricated through electrostatic self-assembly and seed growth methods. The rate constant Kapp is calculated to be 8.63×10−3 s−1 at room temperature for the reduction of 4-nitrophenol to 4-aminophenol with an excessive amount of NaBH4 as a model system showing outstanding catalytic efficiency and stability. For recyclable performance, the catalyst exhibits...
A porous scaffold utilizing hydrophobic protein zein was prepared by the salt-leaching method for tissue engineering. The scaffolds possessed a total porosity of 75.3–79.0%, compressive Young's modulus of (28.2±6.7)MPa–(86.6±19.9)MPa and compressive strength of (2.5±1.2)MPa–(11.8±1.7)MPa, the percentage degradation of 36% using collagenase and 89% using pepsin during 14 days incubation in vitro. The...
