Synthesis, crystal structures, antimicrobial, antifungal and antituberculosis activities of mixed ligand silver(I) complexes
(2013-10-14)
The biological activity of some new mixed silver-phosphane-thio-ligand complexes, with 1:1:2, 1:1:1 and 1:2:1 (Ag:phospine:ligand) compositions, have been examined. Ten compounds were prepared using a series of silver(I) ...
Electrochemical studies of copper-aluminum-silver alloys in 0.5 M H2SO4
(Elsevier B.V., 2001-01-15)
The electrochemical behavior in 0.5 M H2SO4 at 25 degreesC of a Cu-Al(9.3 wt%)-Ag(4.7 wt%) alloy submitted to different heat treatments and an annealed Cu- Al(9.7 wt%)-Ag(34.2 wt%) were studied by means of open circuit ...
Thermal behavior of alpha-(Cu-Al-Ag) alloys
(Springer, 2007-03-01)
Thermal behavior of alpha-(Cu-Al-Ag) alloys, i.e. alloys with composition less than about 8.5 mass% Al, was studied using differential scanning calorimetry (DSC), differential thermal analysis (DTA), scanning electron ...
Infrared-to-visible upconversion in Yb3+/Er3+ co-doped PbO-GeO2 glass with silver nanoparticles
(Elsevier B.V., 2010-10-01)
Enhanced frequency upconversion (UC) emission was studied in Yb3+/Er3+ co-doped PbO-GeO2 glass containing silver nanoparticles (NPs). Optical excitation was achieved with a laser operating at 980 nm in resonance with the ...
A broad study of two new promising antimycobacterial drugs: Ag(I) and Au(I) complexes with 2-(2-thienyl)benzothiazole
(Pergamon-Elsevier B.V. Ltd, 2012-05-11)
Synthesis, characterization, DFT simulation and biological assays of two new metal complexes of 2-(2-thienyl)benzothiazole - BTT are reported. The complexes [Ag(BTT)(2)NO3] - AgBTT2 and [Au(BTT)Cl]center dot 1/2H(2)O - ...
6-Mercaptopurine complexes with silver and gold ions: Anti-tuberculosis and anti-cancer activities
(Elsevier France-editions Scientifiques Medicales Elsevier, 2011-08-01)
Synthesis, characterization and biological studies of silver and gold complexes with 6-mercaptopurine (H2MP) are described. The Ag(I) and Au(I) complexes with HMP-, AgHMP and AuIHMP, were obtained by mixing an acidified ...
Comparative analysis of heteropyknotic chromatin and silver-stained material in Platycarenus umbractulatus (Pentatomidae: Discocephalinae)
(Int Science Services/balaban Publishers, 2011-06-01)
The genus Platycarenus is an unusual member of the subfamily Discocephalinae because it does not have a harlequin lobe. To gather information on this genus, a comparative analysis of heteropyknotic chromatin and silver-stained ...
Cytogenetic analysis in the spermatogenesis of Triatoma melanosoma (Reduviidae; Heteroptera)
(2008-07-30)
Triatomines are of great concern in public health because they are vectors of Chagas' disease. This study presents an analysis of the species Triatoma melanosoma. The cytogenetic characteristics of triatomines include ...
Pt(II) and Ag(I) complexes with acesulfame: Crystal structure and a study of their antitumoral, antimicrobial and antiviral activities
(Elsevier B.V., 2010-05-01)
Two new complexes of platinum(II) and silver(I) with acesulfame were synthesized. Acesulfame is in the anionic form acesulfamate (ace). The structures of both complexes were determined by X-ray crystallography. For ...
