Catalysis of oxygen reduction on Au modified by Pd nanoislands in perchloric acid solution
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
Oxygen reduction reaction (ORR) was studied on polycrystalline gold, Au(poly), modified by nanosized palladium islands in 0.1 M HClO4 solution using rotating disc electrode technique. Paladium was spontaneously deposited ...
Catalysis of Hydrogen Evolution on Au(111) Modified by Spontaneously Deposited Pd Nanoislands
(Springer, New York, 2012)
Hydrogen evolution reaction was studied on Au(111) modified by palladium spontaneously deposited on the Au(111) surface from (1 mM PdSO4 center dot 2 H2O + 0.5 M H2SO4) solution at a submonolayer coverage. Number and size ...
The electrocatalytic properties of carbon supported PtRu/C nanoalloys in oxidation of small organic molecules: Comparison with Pt/C catalyst / Elektrokatalitičke osobine nanočestica legura PtRu/C u oksidaciji malih organskih molekula - poređenje sa katalizatorom Pt/C
(Association of Chemical Engineers of Serbia, 2012)
The electrocatalytic activity of carbon supported PtRu/C catalysts, with different composition, toward the electrooxidation of methanol, CO and formic acid were examined in acid and alkaline solution at ambient temperature ...
Removal of Cu2+ ions using hydrogels of chitosan, itaconic and methacrylic acid: FTIR, SEM/EDX, AFM, kinetic and equilibrium study
(Elsevier, 2011)
A removal of Cu2+ ions from aqueous solutions onto hydrogels of chitosan. itaconic and methacrylic acid has been investigated using batch adsorption technique. The extent of adsorption was investigated as a function of pH, ...
Structural modification of fullerene thin films by highly charged iron ions
(Springer, 2007)
In this paper, the results of structural modification of fullerene thin films bombarded by highly charged iron ions (Fe6+) are presented. The properties of as-deposited and irradiated fullerene thin films have been ...
Particle size effect: Methanol oxidation on supported Pt catalysts
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
The methanol oxidation was studied at two differently prepared supported Pt electrodes (Pt-C/GC and Pt/GC) in 0.5 M H2SO4 and 0.1 M NaOH. The supported Pt electrodes were characterized by AFM, STM TEM and HRTEM. The higher ...
Degradation behaviour of PCL/PEO/PCL and PCL/PEO block copolymers under controlled hydrolytic, enzymatic and composting conditions
(Elsevier Sci Ltd, Oxford, 2017)
Short-term hydrolytic and enzymatic degradation of poly(epsilon-caprolactone) (PCL), one series of triblock (PCL/PEO/PCL) and the other of diblock (PCL/PEO) copolymers, with a low content of hydrophilic PEO segments is ...
Inhibitory effect of cysteine and lanthanides on AA7075‐T6 in neutral NaCl solution
(Weinheim, Germany : Wiley‐VCH GmbH., 2022)
The inhibitory effect of cysteine in the presence of selected lanthanide chlorides (LaCl3, NdCl3, and CeCl3) in a neutral 0.1M NaCl solution was analyzed. The cysteine concentration of 0.3mMwas determined as an optimal ...
Elucidating the antibiofilm activity of Frangula emodin against Staphylococcus aureus biofilms
(Wiley, 2022)
Aims Because the Staphylococcus aureus is one of the most well‐known pathogens associated with medical devices and nosocomial infections, the aim of the study was to examine antibiofilm potential of emodin against it. ...
Novel polyurethane network/organoclay nanocomposites: Microstructure and physicochemical properties
(Elsevier, 2022)
A series of novel polyurethane network/organoclay nanocomposites (PUN-NCs) with different soft segment contents (30–60 wt%) was prepared by in situ polymerization in solution and characterized. PU network (PUN) was made ...
