Protective ability and impedance response of sol-gel reversely transformed ceria conversion coating on aluminium
(Springer, New York, 2016)
Ceria coating is formed on Al from the ceria sol prepared exclusively by forced hydrolysis of Ce(NO3)(4), in order to test their ability to protect Al from corrosion. The characterization of sol-gel-processed ceria coating ...
Antibacterial ability of supported silver nanoparticles by functionalized hydroxyapatite with 5-aminosalicylic acid
(Oxford : Pergamon-Elsevier Science Ltd, 2018)
Antimicrobial performance of silver nanoparticles supported by functionalized hydroxyapatite with 5-aminosalycile acid was tested against Gram-negative bacteria E. coli, Gram-positive bacteria S. aureus and yeast C. albicans. ...
The photocatalytic performance of silver halides - Silver carbonate heterostructures
(Elsevier Science Sa, Lausanne, 2017)
The synthesized rod-like Ag2CO3 particles (2-4 x 0.3-0.6 mu m, length x diameter) served as a precursor for preparation of the AgX/Ag2CO3 (X = CI, I) composites by ion exchange method. The various microstructural (X-ray ...
Synthesis, antimicrobial activity and quantum chemical investigation of novel succinimide derivatives
(Elsevier, 2019)
In the present study, twelve new 1-aryl-3-ethyl-3-methylpyrrolidine-2,5-diones were synthesized and their structures were characterized by FT-IR, 1H NMR, 13C NMR spectroscopy and elemental analysis. In the final step of ...
Tautomerism of 4-phenyl-2,4-dioxobutanoic acid. Insights from pH ramping NMR study and quantum chemical calculations
(Springer/Plenum Publishers, New York, 2018)
Aryldiketo acids (ADKs) exhibit the variety of biological activities, mainly due to large affinity toward divalent metal ions. Metal complexation ability of ADKs, as well as interactions with proteins, depend on tautomeric ...
Reactivity of (E)-4-aryl-4-oxo-2-butenoic acid arylamides toward 2-mercaptoethanol. A LFER study
(Springer Wien, Wien, 2013)
The reactivity of fifteen (E)-4-aryl-4-oxo-2-butenoic (aroylacrylic) acid arylamides toward thiols was studied, measuring the rate constants of the addition of model thiol nucleophile, 2-mercaptoethanol. The influence of ...
Nonlinear frequency response analysis of forced periodic operation of non-isothermal CSTR using single input modulations. Part II: Modulation of inlet temperature or temperature of the cooling/heating fluid
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
Periodic operation of a non isothermal CSTR subject to a single input modulation is analyzed considering a All order reaction and using the nonlinear frequency response (NFR) method, introduced in our previous publications. ...
A novel lectin from the sponge Haliclona cratera: isolation, characterization and biological activity
(Elsevier Science Inc, New York, 2002)
A lectin from the Adriatic sponge Haliclona cratera was purified by ion-exchange and gel chromatography The molecular mass of the lectin is approximately 29 kDa. Purified lectin is rich in hydrophobic and basic amino acids ...
