A superoxide anion radical (O[Formula: see text] nonenzymatic electrochemical sensor based on PtRuCu ternary alloy nanoparticles/electrochemically reduced graphene oxide (ERGO) composite modified glassy carbon electrode (PtRuCu/ERGO/GCE) was developed. ERGO and PtRuCu/ERGO composites were characterized by scanning electron microscopy. The prepared PtRuCu/ERGO/GCE showed remarkable performance toward the electrocatalytic reduction of (O[Formula: see text]. The sensor possessed a high sensitivity of 1725[Formula: see text]A[Formula: see text][Formula: see text][Formula: see text]mM[Formula: see text][Formula: see text]cm[Formula: see text], a wide linear range of 7.5–330[Formula: see text][Formula: see text]M ([Formula: see text]0.993) and a low detection limit of 0.7[Formula: see text][Formula: see text]M ([Formula: see text]/[Formula: see text]), as well as excellent selectivity, reproducibility and stability, which can be attributed to the synergistic effect of ERGO and PtRuCu ternary alloy nanoparticles. Therefore, the prepared sensor is promising for electrochemical determination of O[Formula: see text].

The structure and the magnetic state of ordered Fe65Al35-xMx (Mx = Ga, B; x = 0; 5 at.%) alloys are investigated using X-ray diffraction, Mössbauer spectroscopy, and magnetic measurements. The behavior of the magnetic characteristics and Mössbauer spectra of the binary alloy Fe65Al35 and the ternary alloy with gallium addition Fe65Al30Ga5 is explained in terms of the phase separation into two magnetic phases: a ferromagnetic one and a spin density wave. It is shown that the addition of boron to the initial binary alloy Fe65Al35 results in the ferromagnetic behavior of the ternary alloy.
