Increase of the concentration of dissolved copper in drinking water systems due to flow-induced nanoparticle release from surface corrosion by-products
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Standard measurements of dissolved copper are made by filtering water samples through 0.45 mu m pore-size membranes. However, the surface of corroding metallic surfaces may be covered by topographic features < 0.2 mu m and ...
New insights into mineralogy and geochemistry of allanite-bearing Mediterranean coastal sands from Northern Greece
(Elsevier B.V., 2019-05-01)
Allanite-bearing black coastal sands of Kavala (N. Greece) were studied using a combination of single-crystal XRD, EMPA, mu-XRF, bulk ICP-MS, LA-ICP-MS, mu-XANES and gamma-ray spectrometry. The sands are rich in REE (Sigma ...
Synthesis and thermal behavior study of complexes of the type [Pd(mu-X)(4-eb-p-phen)](2) (X = Cl, Br, I, N-3, NCO, SCN) and 4-eb-p-phen [bis(4-ethylbenzyl)p-phenylenediimine]
(Springer, 2014-10-01)
The Schiff base bis(4-ethylbenzyl) p-phenylenediimine, 4-eb-p-phen (1), and six new dimeric Pd(II) complexes of the type [Pd(mu-X)(4-eb-p-phen)](2) {X = Cl (2), Br (3), I (4), N-3 (5), NCO (6), SCN (7)} have been synthesized ...
Electrochemical Determination of Norepinephrine by Means of Modified Glassy Carbon Electrodes with Carbon Nanotubes and Magnetic Nanoparticles of Cobalt Ferrite
(Mdpi, 2018-04-01)
This study describes the electrochemical preparation of the electrocatalytic oxidation/reduction of noradrenaline in modified glassy carbon of cobalt ferrite nanoparticles and carbon nanotubes (GC/MWCNT/FCo98). The cobalt ...
POTENTIOMETRIC SENSOR BASED ON SILVER SULFIDE NANOPARTICLES SUPPORTED IN CARBONACEOUS MATERIAL FOR THE DETECTION OF FREE CYANIDE
(Soc Brasileira Quimica, 2019-03-01)
Two sensors were synthesized for the detection of free cyanide (CN-), based on silver sulfide nanoparticles (Np-Ag2S) supported on Multiwall Carbon Nanotubes (MWCNT) and hierarchical porous carbon (HPC). The Ag2S/HPC400 ...
Substitution effects on the bulk and surface properties of (Li,Ni)Mn2O4
(2018)
Manganese oxides of spinel structure, LiMn2O4, Li1-x Ni (x) Mn2O4 (0.25 aexae0.75), and NiMn2O4, were studied by EDS, XRD, SEM, magnetic (M-H, M-T), and XPS measurements. The samples were synthesized by an ultrasound-assisted ...
Thin films produced on 5052 aluminum alloy by plasma electrolytic oxydation with red mud-containing electrolytes
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2014-11-01)
In this paper, we propose the production of ceramic protective thin films by plasma electrolytic oxidation using red mud-containing electrolytes. The treatments were performed through the application of pulsed voltage (600 ...
