Journal ArticleDOI
Raman spectra of synthetic sapphire
TL;DR: In this paper, three types of Raman spectra were measured on Sample 1 in the wave number range 100-800 cm −1. In the spectra from the central part of the sample, seven bands were observed, which are in good agreement with a spectrum of natural sapphire.
Journal ArticleDOI
Hydroxylation and dehydroxylation at Cu(III) surfaces
TL;DR: X-ray photoelectron spectroscopy has shown how both chemisorbed oxygen present at a Cu(III) surface and nitric oxide introduced into the gas phase can induce hydroxylation of the surface from an adlayer of molecularly adsorbed water at 80 K.
Journal ArticleDOI
Identification of carbon phases and analysis of diamond/substrate interfaces by Raman spectroscopy
TL;DR: In this article, a method is proposed and experimentally verified for a contactless measurement of the actual substrate temperature by Raman spectroscopy, which is employed to characterize thin diamond and diamond-like carbon films deposited by hot filament chemical vapour deposition (HFCVD).
Journal ArticleDOI
The growth of carbon nanotubes on montmorillonite and zeolite (clinoptilolite)

TL;DR: In this article, the synthesis of carbon nanotubes is described based on activation of methane in a hot filament CVD reactor and subsequent creation of nanostructures on a catalyst pre-treated polished surface of silicon.
Journal ArticleDOI
Study of thorium advanced fuel cycle utilization in light water reactor VVER-440
TL;DR: In this paper, the authors evaluated the results obtained from the spectral code for thorium-based fuel and showed that the fuel cycle with an inert-matrix fuel was the best cycle for minimizing the production of Pu in the VVER-440 reactors.
