A highly selective electrochemical sensor modified with CuFe2O4 nanoparticles and the ionic liquid was constructed for detection of vanillin. The could recognize vanillin from its analogs possible coexistent substances. response peak current concen­tration showed a good linear relationship in range 0.01 - 300.0 μM, sensitivity 0.0923 μA μM-1. limit 0.008 μM (S/N = 3). Besides, reproducibility s...

Copper ferrite films have been deposited on s100d MgO substrates by pulsed-laser deposition. The oxygen pressure used in deposition was varied from 1 to 120 mTorr with the substrate temperature fixed at 700 °C. Magnetization values are measured to increase with oxygen pressure, reaching a maximum value of 2480 G, which is a 42% increase over the bulk equilibrium value. Extended x-ray absorption...
