Behaviour of non-standard composition copper bearing anodes from the copper refining process
(Elsevier, 2010)
This paper addresses on investigation the possibility of electrolytic treatment the sulphur acidic waste solution, obtained in the conventional electrolytic copper refining process. Beside the high copper concentration, ...
Iron complexes of dietary flavonoids: Combined spectroscopic and mechanistic study of their free radical scavenging activity
(Elsevier Sci Ltd, Oxford, 2011)
Combined spectroscopic (UV/visible, Raman, MS) and theoretical approaches were used to assess interaction of iron(III) with quercetin and baicalein in aqueous buffered solutions. Obtained results implicated formation of ...
Cell wall invertase immobilisation within gelatin gel
(Elsevier Sci Ltd, Oxford, 2011)
Yeast cell wall invertase (CWI) was immobilised within 10% gelatin hydrogel. The result of entrapment was the complete immobilisation of all the added CWI. The activity of immobilised biocatalyst was 93 +/- 3 U/g, with ...
Kinetics and mechanism of the formation of poly[(1,1,3,3- tetramethyldisiloxanyl)ethylene] and poly(methyldecylsiloxane) by hydrosilylation
(Wiley-Blackwell, 2007)
The kinetics of the formation of poly(carbosiloxane), as well as of alkylsubstituted poly(siloxane), by Karstedt's catalyst catalyzed hydrosilylation were investigated. Linear poly(carbosiloxane), poly[(1,1,3,3-tetrameth ...
Structural and electrochemical properties of the Li2FeP2O7/C composite prepared using soluble methylcellulose
(Elsevier, 2019)
A new method involving the homogeneous dispersion of precursor compounds inside a methylcellulose matrix is used for the synthesis of a composite powder of Li 2 FeP 2 O 7 and carbon. The properties of carbon-containing and ...
The antimicrobial efficiency of silver activated sorbents
(Elsevier, 2015)
This study is focused on the surface modifications of the materials that are used for antimicrobial water treatment. Sorbents of different origin were activated by Ag+-ions. The selection of the most appropriate materials ...
Effect of boric acid on the porosity of clay and diatomite monoliths
(Elsevier Sci Ltd, Oxford, 2016)
Porous silica ceramics were obtained at low forming pressure (40-80 MPa) and low sintering temperature (850-1300 degrees C) for 4 h in air. Boric acid was used as a low-cost additive, in the amount of 2 wt%. Relatively ...
Engineered surface waves in hyperbolic metamaterials
(Optical Society of America, 2013)
We analyzed surface-wave propagation that takes place at the boundary between a semi-infinite dielectric and a multilayered metamaterial, the latter with indefinite permittivity and cut normally to the layers. Known ...
Adsorption and corrosion inhibitive properties of some organic molecules on iron electrode in sulfuric acid
(Elsevier, 2002)
Adsorption and corrosion inhibitive properties of three different organic molecules: 2-naphthalenesulfonic acid, 2,7-naphthalenedisulfonic acid and 2-naphthol-3,6-disulfonic acid are investigated on Armco-iron electrode ...
Anodic luminescence, structural, photoluminescent, and photocatalytic properties of anodic oxide films grown on niobium in phosphoric acid
(Elsevier, 2015)
This article reports on properties of oxide films obtained by anodization of niobium in phosphoric acid before and after the dielectric breakdown. Weak anodic luminescence of barrier oxide films formed during the anodization ...
