Open circuit potentials of metallic chromium and austenitic 304 stainless steel in aqueous sulphuric acid solution and the influence of chloride ions on them
(Corrosion Science, 2008)
Open circuit potential measurements and cyclic voltammetry of chromium and 304 stainless steel in deaerated aqueous H2SO4 solution of pH 1, without and containing NaCl in the concentration range 1-4 M revealed that chromium ...
Electrochemical and capacitive properties of thin-layer carbon black electrodes
(Journal of Power Sources, 2008)
Electrochemical properties and porous-structure-dependent capacitive ability of commercial carbon blacks, Black Pearls 2000® (BP) and Vulcan® XC 72R (XC), were investigated in H2SO4 solution by cyclic voltammetry (CV) and ...
Alumina/silica supported K2CO3 as a catalyst for biodiesel synthesis from sunflower oil
(Elsevier Sci Ltd, Oxford, 2009)
The new type of catalyst for fatty acid methyl esters (FAME or biodiesel) synthesis with K2CO3 as active component on alumina/silica support was synthesized using sol-gel method. Corresponding catalyst (xerogel) was prepared ...
Glassy carbon electrodes: II. Modification by immersion in AgNO 3
(Elsevier, 2001)
The modification of glassy carbon by immersion in AgNO 3 solution was studied by cyclic voltammetry, vacuum techniques (AES and XPS) and STM. The influence of Ag + concentration, time of immersion, the presence of oxygen ...
Influence of manganese oxide on the activity of Pt/Al2O3 catalyst for CO and n-hexane oxidation
(Elsevier, 2006)
The influence of low loadings of MnOx on the catalytic activity for n-hexene and CO oxidation over highly dispersed Pt on alumina catalysts has been investigated. The applied deposition-precipitation method allows Mn to ...
A refined pharmacophore identifies potent 4-amino-7-chloroquinoline-based inhibitors of the botulinum neurotoxin serotype A metalloprotease
(American Chemical Society (ACS), 2007)
We previously identified structurally diverse small molecule (non-peptidic) inhibitors (SMNPIs) of the botulinum neurotoxin serotype A (BoNT/A) light chain (LC). Of these, several (including antimalarial drugs) contained ...
Removal of organically bound sulfur from oil shale by iron(III)-ion generated-regenerated from pyrite by the action of Acidithiobacillus ferrooxidans - Research on a model system
(Elsevier, 2008)
Oil shale is one of the alternative sources of hydrocarbon fuels ("synthetic petroleum") but is characterized by increased sulfur and nitrogen contents, which represent even greater ecological problems in its use compared ...
Simultaneous production of pullulan and biosorption of metals by Aureobasidium pullulans strain CH-1 on peat hydrolysate
(Elsevier Sci Ltd, Oxford, 2008)
It was demonstrated that during the growth of Aureobasidium pullidans strain CH-1 on the acid hydrolysate of peat from the Vlasina Lake, the content of metals (Cu, Fe, Zn, Mn, Pb, Cd, Ni and Cr) decreased due to biosorption. ...
Are Chelate Rings Aromatic? Calculations of Magnetic Properties of Acetylacetonato and o-Benzoquinonediimine Chelate Rings
(American Chemical Society (ACS), 2007)
The aromaticity of the chelate rings of acetylacetonato (acac) and o-benzoquinonediimine (bqdi) ligands was
investigated theoretically by calculating nucleus-independent chemical shifts (NICS). The calculations were ...
Organocatalyzed cyclizations of π-allylpalladium complexes: A new method for the construction of five- and six-membered rings
(American Chemical Society (ACS), 2007)
Synergic combination of organotransition metal catalysis and organocatalysis allows, for the first time, the Tsuji-Trost cyclization of aldehydes. A catalytic asymmetric variant of the reaction is also possible.
