The comparison of the mean Raman spectrum of worn and unworn (unused) cutting inserts showed that the intensities of the aluminum oxide and titanium nitride bands were decreased, whereas the titanium carbide band at 672 cm(-1) was increased, as a result of the wear effect. Moreover, the ...
Comparing the Raman spectrum of the two irradiated samples with another non-irradiated sample, it was possible to verify that the sample irradiated during 14 days had the greatest values of peak intensity and peak area, indicating a higher concentration of aluminum hydroxide when compared to other ...
The oxide-coated IRE crystal in contact with pure toluene (no PMMA in solution) is used as the background spectrum. The interface spectra are presented in Fig. 1 with increasing adsorption time during the first 24 h after the inlet of the polymer solution. The spectra show a peak at ...
In the current work, the cellular response of compression molded UHMWPE upon reinforcement of bioactive multiwalled carbon nanotubes (MWCNTs) and bioinert aluminum oxide (Al2O3) is investigated. The phase retention and stability were observed using X-ray diffraction, Raman spectroscopy and Fourier ...
Olefin dismutation: Reactions of olefins on cobalt oxide-molybdenum oxide-alumina A study of the conversion of n-butenes into olefins of lower and higher carbon number ("dismutation") on catalysts containing cobalt, molybdenum, and aluminum oxides has shown that the product spectrum is markedly aff...

The profile in the inset (at the right corner of Fig. 2e) exhib- its that the chemical state of Al mainly exist in the form of Al metal and oxide, while the Al oxide should be mostly attributed to the surface oxidation of Al nanoparticles in air atmosphere environment. The XPS ...
By the visual observation of the TEM image (Fig.2b) of nZVAl particles, it could be observed that the particles are semi-spherical, and the majority of the nanoparticles range in size less than 100 nm. Moreover, previous studies reported that the aluminum oxide might represent the outer thi...
Raman spectra were obtained using JobinYvon Micro–Raman Spectroscopy (RamLab–010), equipped with a holographic grating of 1800 lines/mm and a He–Ne laser (633 nm, spot size ∼ 1 μ m) as excitation source. Fourier transform infrared spectrum (FT–IR) measurements were ...
(λ = 532 nm) through the coverslip. By comparing the intensities of Raman signals measured in the bulk electrolyte and measured when aluminum anode was excited, we estimate the Enhancement Factor to be EF = 11.5. The intensity of Raman signals strongly depends on the intensity of...
