Estimation of Lipophilicity of N-Substituted 2-Alkylidene-4-Oxothiazolidines by Means of Reversed-Phase Thin-Layer Chromatography
(Taylor & Francis Inc, Philadelphia, 2011)
The chromatographic behavior of 23 new 2-alkylidene-4-oxothiazolidine derivatives was investigated by means of the reversed-phase thin-layer chromatography (RP TLC) on the C18 and CN stationary phases. Binary mixtures of ...
New potentiometric sensor for copper determination in waste waters based on a new type of modified GC electrode
(Analytical and Bioanalytical Chemistry, 2012)
The potentiometrical analysis of Cu2+ using Nafion- modified electrode with Cu complex with DPABA (Methyl 3,5-bis{bis-[(pyridin-2-yl)methyl]amino}methyl)benzoate) incorporated, is described. Parameters and conditions such ...
In vivo self-hydroxylation of an iron-substituted manganese-dependent extradiol cleaving catechol dioxygenase
(Springer, New York, 2011)
The homoprotocatechuate 2,3-dioxygenase from Arthrobacter globiformis (MndD) catalyzes the oxidative ring cleavage reaction of its catechol substrate in an extradiol fashion. Although this reactivity is more typically ...
Yeast surface display for the expression, purification and characterization of wild-type and B11 mutant glucose oxidases
(Academic Press Inc Elsevier Science, San Diego, 2013)
Glucose oxidase (GOx) catalyzes the oxidation of glucose to form gluconic acid and hydrogen peroxide, a reaction with important applications in food preservation, the manufacture of cosmetics and pharmaceuticals, and the ...
Use of the sulfide minerals pyrite and chalcopyrite as electrochemical sensors in non-aqueous solutions. The potentiometric titration of weak acids in alcohols
(Versita, Warsaw 41, 2009)
Natural monocrystalline pyrite and chalcopyrite were examined as new indicator electrodes for the potentiometric titration of weak acids in tert-butanol and iso-propanol. The electrodes investigated demonstrated a linear ...
Characterization of temperature-sensitive and lipopolysaccharide overproducing transposon mutants of Pseudomonas putida CA-3 affected in PHA accumulation
(Wiley-Blackwell Publishing, Inc, Malden, 2009)
A library of 20 000 transposon (Tn5) mutants of the gram-negative bacterium Pseudomonas putida CA-3 was generated and screened for adverse affects in polyhydroxyalkanoates (PHA) accumulation. Two mutants of interest were ...
Importance of N-terminal proline for the promiscuous activity of 4-oxalocrotonate tautomerase (4-OT)
(Serbian Chemical Soc, Belgrade, 2016)
Michael addition of aldehydes to nitro-olefins is an effective method to obtain useful chiral gamma-nitroaldehydes. gamma-Nitroaldehydes are precursors for chiral gamma-aminobutyric acid analogues, which have numerous ...
Hydrophilic Interaction Planar Chromatography of Geometrical Isomers of Selected Co(Iii) Complexes
(Taylor & Francis Inc, Philadelphia, 2012)
The retention behavior of fourteen geometrically isomeric Co(III) complexes: three pairs of neutral facial-meridional (fac-mer) isomers, one pair of cis-trans isomeric complexes of neutral type, and three pairs of cationic ...
Co(II) impregnated Al(III)-pillared montmorillonite–Synthesis, characterization and catalytic properties in Oxone® activation for dye degradation
(Applied Clay Science, 2019)
Aluminum pillared clay was synthesized and impregnated with Co2+ (CoAP), using incipient wetness impregnation method. The obtained CoAP was characterized by chemical analysis, XRPD, SEM with EDS, XPS and low temperature ...
Synthesis of thiophosphoramidates in water: Click chemistry for phosphates
(Royal Soc Chemistry, Cambridge, 2011)
An aqueous method for the preparation of N,S-dialkyl thiophosphoramidates is reported. Thiophosphorylation of alkylamines was performed using SPCl3 in aqueous reaction media, and the resulting thiophosphoramidate-S-anions ...
