FTIR spectra shows basic characteristics IR band of CoO at 570 cm−1, which indicate presence of CoO vibration and a broad band around 3,440 cm−1 indicative the presence of –OH groups on the nanoparticle surface.
The test may also indicate presence of MM.
The latter could indicate presence of fracturing and weathering at 71 m depth.
Three horizontal lines are shown to indicate presence of the 1F, 2F and 3F traces.
Mineralogical analyses indicate presence of tephra fallout and its impact on fossil diatom communities.
X-ray diffraction (XRD) and magnetization measurements indicate presence of maghemite (γ-Fe2O3) in composite particles.
Obtained results indicate presence of the iron oxide and are found to be in a good agreement with theoretical expectations.
Both SAED and XRD analyses indicate presence of nanoparticles exhibiting structure consistent with that of an f.c.c.
Indeed, the XRD data (Fig. 1, curve 2) indicate presence of both of nickel oxide and pure nickel at this stage of the thermochemical treatment.
Reddy et al. (2004)) stated that low values of stream frequency Sf indicate presence of a permeable subsurface material and low relief.
However, Rask stated that the presence of congenital osseous defects of the lumbosacral spine should indicate presence of nerve root anomalies [24].
