We compare the electronic structure of differently fluorinated copper phthalocyanines (CuPC, CuPCF4, and CuPCF16) using x-ray photoemission spectroscopy valence-band ultraviolet spectroscopy. Whereas ionization potential (IP) is increased by more than 1 eV as a function degree fluorination, further properties such optical gap or composition highest occupied molecular orbital lowest unoccupied remain nearly unchanged. This fact renders these compounds an ideal tool for investigation influence...
We report a detailed experimental and theoretical study on the electronic optical properties of highly boron-substituted (up to $15\phantom{\rule{0.3em}{0ex}}\text{at.}%$) single-wall carbon nanotubes. Core-level electron energy-loss spectroscopy reveals that boron incorporates into lattice structure tubes, transferring $\ensuremath{\sim}1∕2$ hole per atom derived unoccupied density states. The charge transfer calculated Fermi-energy shift in doped nanotubes evidence simple rigid-band model...
Abstract Electron inelastic mean free paths (IMFP) have been estimated for Ti, TiC, TiN and TiO 2 energies between 250 2000 eV. The IMFP values derived from the respective energy‐loss function (i.e. Im{−1/ ϵ }) on basis of model developed by Yubero Tougaard quantitative analysis using reflection electron spectra (REELS). IMFPs analysed in terms Bethe equation scattering compared with predicted TPP‐2M equation. We distinguished λ REELS ( E 0 ) ∞ ), whereby first takes into account surface...
We report on electron energy-loss spectroscopy studies of the electronic properties multiwall boron nitride nanotubes, in terms $\mathrm{B}1s$ and $\mathrm{N}1s$ excitation edges q-dependent function. The dielectric function shows a strong dispersion momentum \ensuremath{\pi} $\ensuremath{\sigma}+\ensuremath{\pi}$ plasmons indicating that they are spatially delocalized along tube axis as expected according to their characteristic two-dimensional graphiticlike structure, nondispersing...
We report the infrared (IR) response of bulk samples multiwalled boron nitride nanotubes, produced by a substitution reaction from single walled carbon which is dominated two characteristic BN-vibrations at 800 and 1372 cm-1.
The sewage sludge dewatering produced by wastewater treatment plants (WWTP) is a multifaceted process due to the presence of colloid fractions. Electro-osmosis could be suitable technique reduce water content final sludge. Electric fields 10, 15, and 20 V/cm have been studied for electro-osmosis tests under pressure static or rotating piston, obtaining dry solids up 40–45%, with respect 25–30% obtained mechanical methods. In order optimize process, corrosion behavior wear anodic material...
The application of surface treatments that incorporate silver or copper as antibacterial elements has become a common practice for wide variety medical devices and materials because their effective activity against nosocomial infections. Ceramic tiles are choice cladding the floors walls operation rooms other hospital spaces. This study is focused on deposition biocide physical vapor (PVD) coatings glazed ceramic tiles. objective was to provide surfaces without worsening mechanical...
Structural properties of calcined ${\mathrm{ZrO}}_{2}$ nanopowders having various sizes were investigated by Raman spectroscopy, x-ray diffraction, and high-resolution transmission electron microscopy. For grain the order a few nanometers spectrum is typical an amorphous material as corresponding diffractogram. As size grains increases, spectra progressively evolve towards that crystallized sample, furthermore, two regimes growth, vitreous crystalline, are evidenced. opposed to acoustical,...
