Trace Molybdenum determination in drinking waters by USN-ICP-OES after solid phase extraction on Ethyl Vinyl Acetate turnings-packed minicolumn
(Perkin-elmer Corp, 2008-01)
This study presents the development of a novel on-line preconcentration method for inorganic molybdenum by flow injection solid-phase extraction with detection by inductively coupled plasma optical emission spectrometry ...
A novel on-line preconcentration method for trace molybdenum determination by USN-ICP OES with biosorption on immobilized yeasts
(Elsevier Science, 2007-08)
A new system for on-line preconcentration of molybdenum by sorption on a minicolumn associated to inductively coupled plasma - optical emission spectrometry with ultrasonic nebulization was studied. It is based on the ...
Molybdenum incorporation on AB 2 alloys-Part II. On the synergetic effects of Laves and non-Laves phases
(Elsevier Science Sa, 2018-03-15)
Molybdenum substitution by chromium in ZrCr1-xNiMox alloys produces the segregation of ZrxNiy phases, ZrCr2 and ZrMo2 Laves phases as it was stated in Part I of this paper. In order to study the contribution of these phases ...
Tris(pyrazolyl)methane ligands: Syntheses and structures of monometallic and metallodendritic complexes
(Wiley VCH Verlag, 2004-08)
The substituted ligands Me3SiC(pz)3 and Me 3SiOCH2C(pz)3 (2) have been prepared starting from HC(pz)3 and HOCH2C(pz)3. The molecular structure of compound 1 has been determined by X-ray diffraction studies, which show a ...
Enhanced hydrogen evolution activity of Ni[MoS2] hybrids in alkaline electrolyte
(Springer, 2020-05)
In this paper is presented a simple one-pot synthesis of a composite electrode with a non-noble metal for the catalysis of hydrogen evolution reaction in alkaline media. The Ni[MoS2] composite electrocatalyst has been ...
Analysis of electron beam damage of exfoliated MoS2 sheets and quantitative HAADF-STEM imaging
(Elsevier Science, 2014-06)
In this work we examined MoS2sheets by aberration-corrected scanning transmission electron micro-scopy (STEM) at three different energies: 80, 120 and 200 kV. Structural damage of the MoS2sheets hasbeen controlled at 80 ...
Performance of coated steel systems exposed to different media: Part I. Painted galvanized steel
(Elsevier Science Sa, 2004-08)
The performance of different pre-treated galvanized steel/primer/topcoat paint systems applied on hot-dip galvanized steel sheets has been studied. Each panel was pre-treated with 5% Fe(NO3)3+15% H 3PO3 solution. After ...
Oral exfoliative cytology and corrosion of metal piercings: Tissue implications
(Springer Heidelberg, 2019-04)
Objectives: A group of adolescents with oral piercings was studied to determine the presence of metallic particles in cells exfoliated from the mucosa surrounding their metal oral piercings and the association between such ...
Optimization of continuous arsenic biosorption present in natural contaminated groundwater
(John Wiley & Sons Ltd, 2019-02)
BACKGROUND: Arsenic (As) is a serious water pollution problem in the world. In Argentina, it is related to old volcanic activities; for example, the western region of Santa Fe State has concentrations higher than 0.1 mgAs ...
Contents and main fractions of trace elements in Typic Argiudolls of the Argentinean Pampas
(Taylor & Francis, 2000-12)
The knowledge of the trace elements in soils of the Pampas remains fragmentary. Agriculture has been intensified in this region increasing the crop demand of micronutrients and increasing the use of fertilizers, which could ...
