On the choice of optimal conformation in linear free-energy relationships. Reactivity of 2-[(carboxymethyl)sulfanyl]-4-oxo-4-arylbutanoic acids with diphenyldiazomethane
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Rate constants for the esterification of eleven 2-[(carboxymethyl)sulfanyl]-4-oxo-4-arylbutanoic acids with diphenyldiazomethane in ethanol at 30 degrees C were determined, and correlated with substituent constants using ...
Myeloperoxidase-mediated oxidation of organophosphorus pesticides as a pre-step in their determination by AChE based bioanalytical methods
(Springer Wien, Wien, 2010)
In order to improve the sensitivity of assays for inhibitors of the enzyme acetylcholine esterase (AChE), an effective method was developed for the conversion of the organophosphate pesticides (OPs) diazinon, malathion, ...
Corrosion stability of cerium-doped cataphoretic epoxy coatings on AA6060 alloy
(Wiley-VCH Verlag Gmbh, Weinheim, 2016)
In this study, corrosion protection efficiency of undoped epoxy and epoxy coating doped with cerium on aluminum alloy AA6060 is evaluated over prolonged exposure to 3wt% NaCl solution by electrochemical impedance spectroscopy ...
The Role of SnO2 on Electrocatalytic Activity of PtSn Catalysts
(Springer, New York, 2018)
In our previous paper, we described in detail studies of Sn influence on electrocatalytic activity of PtSn catalyst for CO and formic acid oxidation (StevanoviAc et al., J. Phys. Chem. C, 118 (2014) 278-289). The catalyst ...
Novel biosensor films based on chitosan
(Elsevier Science Bv, Amsterdam, 2016)
Films of chitosan and poly(itaconic acid) in various different ratios have been prepared by membrane casting. The enhancement in the proton conductivity and uptake of water was observed as the content of poly(itaconic acid) ...
Recovery of (-)-epigallocatechingallate (EGCG) from aqueous solution by selective adsorption onto spent coffee grounds
(Springer, New York, 2015)
Activated carbons from spent coffee grounds have been prepared for column adsorption of main green tea polyphenol (-)-epigallocatechingallate (EGCG). The response surface methodology was used to estimate the influence of ...
Synthesis, structure, and solvatochromic properties of pharmacologically active 5-substituted 5-phenylhydantoins
(Springer Wien, Wien, 2011)
A series of 5-substituted 5-phenylhydantoins was synthesized and their UV absorption spectra were recorded in the region 200-400 nm in selected solvents of different polarity. The effects of solvent dipolarity/polarizability ...
Adding Value to the Oil Cake as a Waste from Oil Processing Industry: Production of Lipase and Protease by Candida utilis in Solid State Fermentation
(Springer, New York, 2012)
Olive oil cake is a by-product from the olive oil processing industry and can be used for the lipase and protease production by Candida utilis in solid state fermentation. Different carbon and nitrogen sources were evaluated, ...
Synthesis, characterization and antimicrobial activity of copper and zinc-doped hydroxyapatite nanopowders
(Elsevier, Amsterdam, 2010)
Antimicrobial materials based on hydroxyapatite are potentially attractive in a wide variety of medical applications. The synthesis of copper and zinc-doped hydroxyapatite was done by neutralization method. This method ...
Mathematical Model of Gentamicin Sulfate Release from a Bioactive Textile Material as a Transdermal System Under In Vitro Conditions
(John Wiley & Sons Inc, Hoboken, 2010)
A mathematical model was developed to estimate the release of gentamicin sulfate from a bioactive textile material as a transdermal system for wound dressing. The gentamicin sulfate released from the antibiotic/chitosan ...
