2011-4-18 · Optical microscopy, XRD, SEM/EDAX and EPMA techniques were used to characterise the coatings. The thermogravimetric technique was used to establish kinetics of corrosion. The structure of the as sprayed Cr3C2-NiCr coating mainly consisted of ¥ã-nickel solid solution with very low intensity peaks of Cr7C3 and Cr2O3 phases.

Consequently, FESEM, Hi-TEM, XRD, ICP-OES, CHNS, FTIR and UV–Vis analyses were done on the nanohybrids. The result of XRD analysis indied successful intercalation of the Gd and PA as well the adsorption of AuNPs. The UV–Vis release study showed 90% of the intercalated drug was released at pH 4.8, which is the pH of the cancer cells.


2012-1-4 · The anodic peaks of DA and ascorbic acid (AA) in their mixture can be well separated by the prepared electrode. Under optimum conditions linear calibration graphs were obtained over the DA concentration range 2.0 × 10- 6 to 5.0 × 10 - 5 M with a correlation coefficient of 0.998 and a detection limit of 9.0 × 10- 8 M (S/N = 3).

X-ray diffraction spectroscopy (XRD) The crystalline structure, size, and shape of the unit cell and the crystallite size of a material can be determined using X-ray diffraction spectroscopy (XRD). Usually, X-ray diffraction peaks were observed at 2θ = 38.00 , 44.16 , 64.40 , and 77.33 , which correspond to (111), (200), (220), and (311) Bragg

The plastic layer was observed to have a prevalence for increasing 500-1000 Da structures though this formed part of the larger molecular weight range. Resolidifiion of the plastic layer coincided with a rise in 4000 Da structures. The semi-coke spectrum had a series of repeating peaks separated by 24 Da extending from 1000 Da to 3000 Da.

The shape of XRD peaks is asymmetric owing to the stress between the substrate and the thin film. The electric conductivity of sample grown in low oxygen pressure is n-type semiconductor. However, the samples grown in high oxygen pressure were insulator.

FTIR-spectra of MHDA shows the line at 2500 cm-1 attributed to thiol group which is modified by presence of Au-NPs, suggesting the formation of bond between thiol group and gold. We also can observe the peaks originate from characteristic chemical group. A Raman spectrum of the same sample is also promising.

The samples are then ground and polished using a succession of silicon carbide papers and diamond suspensions, finishing with colloidal silica. Samples are then examined using SEM, TEM and EDX. 6

Amethyst: Mineral information, data and localities.

Amethyst is pleochroic (Haidinger, 1847; Pancharatnam, 1954; Raman, 1954): when the polarization of the light is changed from parallel to the c-axis to perpendicular to the c-axis, amethyst changes its color from blue-violet to purple.

Figure 4 shows XRD patterns of the strongest YSZ peak for YSZ scaffolds as a function of glucose:metals molar ratio. The crystallite size was calculated using these peaks and the Scherrer equation. The crystallite size decreased from 22 nm to 12 nm to 9 nm as the glucose:metals molar ratio was increased from 0:1 to 2.25:1 to 4.5:1.

The XRD pattern of the N-doped CSEINPs after being used in the recycling test is shown in Figure 14, which reveals that the phase composition includes graphitic carbon, Fe, Fe 3 C, Fe 3 O 4, and Austenite CFe 15.1. Compared with Figure 6, the peaks of the primary phases still exist, but the peaks of Fe 3 O 4 and amorphous carbon (ca. 23
