Orientation-dependent response of defective Tantalum single crystals
(Elsevier, 2014-05)
Defective Tantalum monocrystals are expected to display a particularly rich behavior when stressed along different directions. Using molecular dynamics simulations, we model Ta monocrystals containing a single spherical ...
Correlation between structural data and spectroscopic studies of a new beta-diketonate complex with trivalent europium and gadolinium
(Royal Soc Chemistry, 2011-01-01)
This paper reports the study of structural and luminescence parameters of a seven-coordination compound containing beta-diketone butyl methoxy-dibenzoyl-methane (bmdm) and triphenylphosphine oxide (tppo), both acting as ...

Electron microscopy study of the carbon-induced 2H-3R-1T phase transition of MoS2
(Royal Society of Chemistry, 2020-01)
Phase transition of molybdenum disulfide (MoS2) was carried out in a pure monocrystal using a combination milling and heating process. Decanoic acid was used as a carbon source to promote the exfoliation of the layers of ...
One-Dimensional TiO2-B Crystals Synthesised by Hydrothermal Process and Their Antibacterial Behaviour on Escherichia coli
(Hindawi, 2016)
We have successfully synthesised one-dimensional single crystals of monoclinic phase titanium dioxide nanostructures (TiO2-B), prepared by a hydrothermal process. Morphological characterization was carried out by atomic ...
Diterpenoid Glycosides from the Bitter Fern Gleichenia quadripartita
(American Chemical Society, 2007-12)
Fifteen new diterpenoid glycosides (1a–n, 2) were isolated from an Argentine collection of the bitter fern Gleichenia quadripartita along with the known flavonoid glycoside afzelin. Structure elucidation was accomplished ...
Anisotropy-based mechanism for zigzag striped patterns in magnetic thin films
(American Physical Society, 2014-05)
In this work, we studied a two-dimensional ferromagnetic system using Monte Carlo simulations. Our modelincludes exchange and dipolar interactions, a cubic anisotropy term, and uniaxial out-of-plane and in-planeones. ...
Síntese, caracterização e avaliação da atividade peroxidase de novos complexos de cobalto com ligantes derivados do piridoxal
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2017-02-16)
This work treat with the synthesis and characterization of new cobalt complexes with ligands derived from pyridoxal and their application as mimetics of the enzyme peroxidase. The complexes were structurally characterized ...
Influence of phase transition on pattern formation during catalytic reactions
(Elsevier, 2000-10)
We investigate the influence of the order of surface phase transitions on pattern formation during chemical reaction on mono-crystal catalysts. We use a model consisting of two partial differential equations, one of which ...
