Sentence examples for trace of impurity from inspiring English sources

The XRD spectrum of the nanoparticles shown in Fig. 1d confirms the formation of pure NiO without any trace of impurity.

X-Ray Diffraction (XRD) patterns revealed tetrahedrite as the main phase, whereas for the compounds with x = 0, 0.5 a trace of impurity phase Cu3SbS4 was observed.

The main diffraction peaks matched well with the kesterite CZTS from the XRD patterns, confirming that the major phase of the sample should be kesterite structure although a little trace of impurity CuS was found.

Especially, in the sample synthesized in the high-concentration TA solution (CZTS TA = 1 8), it is hardly to find any trace of impurities.

The surface chemical composition of all the three ZnO nanowire arrays have been characterized by means of XPS to detect any trace of impurities in the samples and to assess the vertical compositional homogeneity, as shown in Figure 2. The insets are the high resolution spectra recorded for the Zn and O regions.

This step was applied to remove the remaining trace of impurities from earlier step.

No traces of impurity phases have been revealed (Fig. 2).

s-IPNs exhibit remarkable stability towards lithium metal and no traces of impurity are detected while testing their oxidation stability (4.7 V vs. Li/Li+) towards anodic potential.

The nucleation and growth kinetics the governing processes in this operation can often be profoundly influenced by mere traces of impurity in the system; a few parts per million may alter the crystalline product beyond all recognition.

It is seen that all the diffraction peaks for the bare SrTiO3 particles and the composites can be index to the cubic structure of SrTiO3, and no traces of impurity phases are detected.
