(AMER PHYSICAL SOC, 2012-01-04)We study discrete surface solitons in semi-infinite, one-dimensional, nonlinear (Kerr), quasiperiodic waveguide arrays of the Fibonacci and Aubry-Andre types, and explore different families of localized surface modes, as ...
-
(Elsevier, 2015)The (110) surface of iron fluoride (FeF2) is especially relevant to the understanding of the exchange bias phenomenon, which has important applications in the sensor industry, and has been extensively explored, both ...
-
(Elsevier, 2002)A complete assignment of the infrared spectra of the title macrocycles was carried out on the basis of well-documented references and a normal coordinate analysis based on a simplified molecular model. The structure of the ...
-
(Royal Society of Chemistry, 2022)In this study, we investigate chromium-doped spinels (CDSs) and their characteristic red photoluminescence (PL) due to the strong crystal field and octahedral coordination geometries of the Cr3+ ions. An increase in the ...

Surface-enhanced Raman scattering and density functional theory studies of bis(4-aminophenyl)sulfone (2010)Raman and surface-enhanced Raman scattering (SERS) spectra of dapsone by using colloidal silver nanoparticles have been recorded. Density functional theory was used for the optimization of ground state geometries and ...

Surface-enhanced Raman scattering and theoretical study of the bilichromes biliverdin and bilirubin (Taylor and Francis Inc., 2016)© 2016, Copyright © Taylor & Francis Group, LLC. The surface-enhanced Raman scattering spectra of biliverdin and bilirubin were obtained and analyzed; a physical silver ligand interaction was inferred. The structural ...
-
(2009)Surface-enhanced Raman scattering (SERS) spectra of tryptophan (Trp) were obtained. A unique SERS spectrum of Trp, corresponding to the most stable conformation and orientation on the metal surface, is observed after a ...
-
(American Chemical Society, 2000)The surface-enhanced Raman scattering (SERS) spectra for phthalimide (PIMH) vacuum evaporated, cast onto silver island films, and from colloidal silver are clearly identified with the formation of a phthalimide-silver ...
-
(2001)The FT-Raman spectra and surface-enhanced Raman scattering (SERS) on silver colloid of the azabipiridyl ligand and its Co(II), Ni(II) and Cu(II) complexes are reported. A resonance Raman (RR) study of the solids and a ...
-
(2003)We analysed the residual resistivity data for more than 40 films of COSi2 reported by different groups using the available quantum theories of size effects in metal films. We found that the predictions of the model of ...
-
(1999)We report an extension of the theory of Sheng, Xing and Wang (SXW) (Sheng L, Xing D Y and Wang Z D 1995 Phys. Rev. B 51 7325), which permits the calculation of size effects from the statistical properties that characterize ...
-
(2002)We have extended the modified formalism of Sheng, Xing, and Wang [J. Phys.: Condens. Matter 11 L299 (1999)] to allow the calculation of the conductivity of a thin metallic film bounded by a rough fractal surface. We utilized ...

-
(1999)We performed in situ experiments during the summer of 1995 and 1996 to assess the potential effect of solar ultraviolet B (UVB) radiation (290-320 nm) on the survival of Cyclops abyssorum tatricus Kozminski and Boeckella ...
-
(Universidad de Chile., 2018)La Septicemia Rickettsial Salmonídea (SRS) es una enfermedad que afecta a las especies salmónidas, causada por la bacteria Piscirickettsia salmonis, y que causa pérdidas de millones de dólares en la industria salmonera ...
-
(Universidad de Chile., 1984)Esta tesis consiste en poner en funcionamiento la técnica experimental para medir susceptibilidades magnéticas al variar la temperatura.
-
(Pontificia Universidad Catolica de Chile, Facultad de Agronomia e Ingenieria Forestal, 2018)Canes obtained from one-year-old stems of the grapevine cultivars Cabernet Franc, Malbec, Merlot, Sauvignon Blanc and Syrah (all non-grafted) were used as models to test their susceptibility to Diplodia seriata and ...
-
(1973)We have investigated the susceptibility of the Mattis Hamiltonian by means of Green's-function techniques and using a functional-integral formulation. It turns out that it is not possible to obtain an exact solution for ...
