Propriedades estruturais e eletrônicas de nanofilmes de TiO2 anatase: cálculos B3LYP-D* em sistemas periódicos bidimensionais
(Sociedade Brasileira de Química, 2014)
Structural and electronic properties of titanium dioxide (TiO2) thin films, in anatase phase, were investigated using periodic 2D calculations at density functional theory (DFT) level with B3LYP hybrid functional. The ...
DFT-based investigation of the electronic structure of a double-stranded AC B-DNA dimmer at different levels of theory.
(2013-06-28)
Calculations of the electronic structure of a stacked dimmer sequence from the D-(GCAAACGTTTGC)2 B-DNA dodecamer resolved in a PDB file 1HQ7 are performed within density functional theory. Seeking to understand the minimum ...

First-principles simulation of elastic constants and electronic properties of GaN
(2014)
The electronic and structural properties and elastic constants of the wurtzite phase of GaN, was investigated by computer simulation at Density Functional Theory level, with B3LYP and B3PW hybrid functional. The electronic ...
Interplay between dihydrogen and alkali–halogen bonds: Is there some covalency upon complexation of ternary systems?
(Brasil, 2012)
In this study, a theoretical investigation of traditional dihydrogen bonds and novel alkali–halogen bonds was performed in relation to the formation of NaH⋯HCF3 and NaH⋯HCCl3 binary and NaH⋯2(HCF3) and NaH⋯2(HCCl3) ternary ...
Theoretical and experimental study of the infrared spectrum of isonicotinamide
(Elsevier B.V., 2006-04-28)
The IR-spectrum of the isonicotinamide molecule (C(2)H(2)NC(3)H(2)CONH(2)) is studied by means of theoretical and experimental methods. For an appropriate representation of the molecular environment, Gaussian basis sets ...

Synthesis of new cyano-substituted analogues of Tröger's bases from bromo-derivatives. A stereochemical dependence of long-range ( n J HH , n = 4, 5, and 6) proton-proton and proton-carbon ( n J CH , n = 1, 2, 3, 4, and 5) coupling constants of these compounds
(John Wiley & Sons Ltd, 2019-04)
A free-catalyst microwave-assisted cyanation of brominated Tröger´s base derivatives (2a-f) is reported. The procedure is simple, efficient and clean affording the nitrile compounds (3a-e, I) in very good yields. Complete ...
