Influência da adição de antimônio na liga hipoeutética Sn52%Bi solidificada direcionalmente: parâmetros térmicos, microestruturais e resistência mecânica
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE MATERIAIS, 2019-07-17)
The search for sustainable and less toxic materials is a global trend and
should draw even more attention in the coming years due to the new and current
restrictions/directives of environmental agencies. Lead-free solder ...
Propriedades ópticas de filmes semicondutores GaAsBi e GaSbBi
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2022-05-02)
Bismuth-diluted III-V are interesting materials for possible applications in optoeletronic and spintronic devices. If we add a small amount of Bi in III-V materials, we observe a strong reduction in the band gap energy. ...
Estudo da interação do As(III) com modelo "zinc finger" da proteína NCp7 HIV-1 e complexos de Bi(III) e Sb(III) com ligantes contendo 2-mercapto-imidazol
(Universidade Federal de Minas GeraisUFMG, 2010-12-17)
The ejection of zinc from its coordination site in Zn-finger protein can be promoted by other metal species through competitive binding. This is considered as a promising strategy to inactivate the Zn-finger protein and ...
Intercalation of polyethylene oxide in layered thiophosphate of Bi and Sb
(SOC CHILENA QUIMICA, 2008-06)
The intercalation compounds Li0.43(PEO)2.4(H2O)1.4K0.57BiP2S6 and Li0.38(PEO)2.1(H2O)1.6K0.62SbP2S6 have been synthesized by the insertion of polyethylene
oxide PEO in LiKMP2S6 (M=Bi, Sb), that contained Li+ and K+ ...
Evaluation of sample treatment for the simultaneous flow injection hydride generation and determination of As, Bi, Sb and Se by GRAS
(Perkin-elmer Corp, 2004-05-01)
A new method was developed for the simultaneous determination of As, Bi, Sb, and Se by flow injection hydride generation graphite furnace atomic absorption spectrometry. An alternative two-step sample treatment procedure ...
