The novel ultrasound-assisted co-precipitation method was successfully applied for the synthesis of NiFe2O4 catalyst, which offered advantages lower particle size and better crystalline structure without affecting phase planes. Furthermore, efficacy synthesized catalysts evaluated using catalytic degradation Chrysoidine R dye. study designed to evaluate effect different parameters, such as pH, ...

The temperatures and pressures influencing the formation mechanism of passive film corrosion products, as well passivation performance 2205 duplex stainless steel (DSS), were systematically studied via immersion tests, electrochemical measurements, various advanced surface techniques. results indicate that at 150 °C was an amorphous structure, while products comprised nano-polycrystalline FeCr2...
