Synthesis of EPA- and DHA-enriched structured acylglycerols at the sn-2 position starting from commercial salmon oil by enzymatic lipase catalysis under supercritical conditions
(MDPI, 2021)
There is consistent evidence that long-chain polyunsaturated fatty acids (LCPUFA) belonging to the n-3 series, i.e., eicosapentaenoic (20:5n-3, EPA) and docosahexaenoic (22:6n-3, DHA) acids, decrease the risk of heart, ...
A theoretical study of SnF2+, SnCl2+, and SnO2+ and their experimental search
(AMER INST PHYSICSMELVILLE, 2012-10-21)
We present a detailed theoretical study of the stability of the gas-phase diatomic dications SnF2+, SnCl2+, and SnO2+ using ab initio computer calculations. The ground states of SnF2+, SnCl2+, and SnO2+ are thermodynamically ...
Evolution of the doping regimes in the Al-doped SnO2 nanoparticles prepared by a polymer precursor method
(IOP Publishing, 2015)
In this study, we report on the structural and hyperfine properties of Al-doped SnO2 nanoparticles synthesized by a polymer precursor method. The x-ray diffraction data analysis carried out using the Rietveld refinement ...
Avaliação microestrutural da liga Sn-2%Ag-0,7%Cu (SAC207) submetida à tratamento térmico de envelhecimento.
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia de Materiais, 2019-09-18)
Although there are still few studies on lead-free alloys (Pb), in recent years some alternative alloys have been studied, since the presence of this element poses a threat to human health due to its high toxicity. In the ...
Microestrutura, parâmetros térmicos e citotoxicidade da liga hipoeutética Sn-2,0%Ag modificada com 0,2%Ni
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE MATERIAIS, 2022-07-11)
The addition of nickel (Ni) in tin-based alloys applied to microelectronic components has
received special attention in recent years. Ni promotes changes in mechanical strength,
toughness, creep resistance, and electrical ...
On the Progenitor and Supernova of the SN 2002cx-like Supernova 2008ge
(2010)
We present observations of supernova (SN) 2008ge, which is spectroscopically similar to the peculiar SN 2002cx, and its pre-explosion site that indicate that its progenitor was probably a white dwarf. NGC 1527, the host ...
Avaliação do Tratamento Térmico de Envelhecimento na Liga Sn-0,7%Cu-0,05%Ni
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia de Materiais, 2019-09-19)
Investigations about the effect of thermal cycles (variations of time and temperature) on the microstructures of Pb-free solder alloys are scarce in the literature. Thus, this work aims to perform a microstructural analysis ...
POSITIVE MATRICES WITH PRESCRIBED SINGULAR VALUES

We present observations of supernova (SN) 2008ge, which is spectroscopically similar to the peculiar
SN 2002cx, and its pre-explosion site that indicate that its progenitor was probably a white dwarf.
