Layered double hydroxides-indomethacin nanohybrids : intercalation, pH influence, stability and release properties
(2016)
In this work, three pH values (8, 9 and 10) were studied for the insertion of Indomethacin (Indo) molecules into Layered Double Hydroxides (LDHs). The obtained results showed that the LDH materials have been a good storage ...

Analysis of X-ray absorption spectra of the K and L 2,3 edges of GaN within the FP-LAPW method
(2016)
Gallium nitride, GaN, is a semiconductor material with several technological applications and therapeutic potential to inhibits the proliferation of tumor cells. In this work we performed all electron self consistent ...
Structure of the Ru, Ag and Te L X-ray emission spectra
(2016)
The emission of X-rays in atomic transitions from L-shell vacancy states of Ru, Ag and Te induced by electron incidence was studied. To this end, L X-ray spectra were measured with a wavelength dispersive spectrometer, and ...
One-dimensional singular problems involving the p-Laplacian and nonlinearities indefinite in sign
(2016)
Let Ω be a bounded open interval, let p > 1 and γ >, and let m : Ω → ℝ be a function that may change sign in Ω. In this article we study the existence and nonexistence of positive solutions for one-dimensional singular ...
Spectra of lens spaces from 1-norm spectra of congruence lattices
(2016)
To every n-dimensional lens space L, we associate a congruence lattice L in Zm, with n = 2m−1 and we prove a formula relating the multiplicities of Hodge-Laplace eigenvalues on L with the number of lattice elements of a ...
Efecto del itrio en las propiedades estructurales y magnéticas de la ferrita de cobalto
(2016-03)
Se estudian las propiedades magnéticas y estructurales de la ferrita de cobalto, con la inclusión de itrio en distintas concentraciones. Se observa y explica cómo cambian esas propiedades antes y después de realizar un ...
Proving correctness of a compiler using step-indexed logical relations
(2016)
In this paper we prove the correctness of a compiler for a call-by-name language using step-indexed logical relations and biorthogonality. The source language is an extension of the simply typed lambda-calculus with ...
Localization of the valence electron of endohedrally confined hydrogen, lithium and sodium in fullerene cages
(2016)
The localization of the valence electron of H, Li and N a atoms enclosed by three different fullerene molecules is studied. The structure of the fullerene molecules is used to calculate the equilibrium position of the ...
