Ultraviolet diversity of type Ia supernovae
(Oxford University Press, 2016-09)
Ultraviolet (UV) observations of Type Ia supernovae (SNe Ia) probe the outermost layers of
the explosion, and UV spectra of SNe Ia are expected to be extremely sensitive to differences
in progenitor composition and the ...
Synthesis and Crystal Structures of Octahedral Sn(IV) Complexes Prepared from SnCl(2)center dot 2H(2)O and 2-Hydroxyacetophenone (S-benzydithiocarbazate) Ligand (H(2)L)
(SPRINGER/PLENUM PUBLISHERS, 2011)
Two coordination octahedral Sn(IV) complexes [Sn(L)(2)] and cis-[SnCl(2)(L)(dmso)], where H(2)L is 2-hydroxyacetophenone (S-benzydithiocarbazate), were prepared and characterized by elemental analysis, IR, NMR ((1)H, (13)C), ...
Two transitional type Ia supernovae located in the Fornax cluster member NGC 1404: SN 2007on and SN 2011iv
(EDP Sciences, 2018-03)
We present an analysis of ultraviolet (UV) to near-infrared observations of the fast-declining Type Ia supernovae (SNe Ia) 2007on and 2011iv, hosted by the Fornax cluster member NGC 1404. The B-band light curves of SN ...

Study of the hydrostatic pressure on orthorhombic IV–VI compounds including many-body effects
(Elsevier Science, 2011-05)
We performed a fully ab initio study of the relaxed volume optimization of the four orthorhombic IV–VI compounds (GeS, GeSe, a-SnS and SnSe), finding good agreement with experimental data from the literature. Based on the ...
Group IV Graphene- and Graphane-Like Nanosheets
(AMER CHEMICAL SOC, 2011)
We performed a first-principles investigation on the structural and electronic properties of group IV (C, SiC, Si, Ge, and Sn) graphene-like sheets in flat and buckled configurations and the respective hydrogenated or ...
Sobre autovalores do Laplaciano e Bi-harmônico em Variedades Riemannianas e do Poli-harmônico e Rn e Sn
(2011-06-29)
Um problema com muitas aplicações físicas é estimar os autovalores do operador de Laplace e suas generalizações. Neste trabalho, apresentamos algumas cotas universais para os autovalores dos operadores Laplaciano e ...
