Modeling and optimization process parameters of acid activation of bentonite by response surface methodology
(Elsevier, 2010)
The effect of acid activation on the textural properties of a bentonite from Serbia was investigated using response surface methodology. The influence of activation parameters (temperature, time, acid normality, solid-to-liquid ...
Palladium(II) complexes with R(2)edda derived ligands. Part IV. O,O '-dialkyl esters of (S,S)-ethylenediamine-N,N '-di-2-(4-methyl)-pentanoic acid dihydrochloride and their palladium(II) complexes: Synthesis, characterization and in vitro antitumoral acti
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2010)
Four novel bidentate N,N'-ligand precursors, including O,O'-dialkyl esters (alkyl = ethyl, n-propyl, n-butyl and n-pentyl), L1 center dot 2HCl-L4 center dot 2HCl, of (S,S)-ethylenediamine-N,N'-di-2-(4-methyl)-pentanoic ...
Effect of parameters of square-wave pulsating current on copper electrodeposition in the hydrogen co-deposition range
(Elsevier Science Inc, New York, 2010)
Copper electrodeposition processes in the hydrogen co-deposition range by the pulsating current (PC) regime were examined by the determination of the average current efficiency of hydrogen evolution and by the scanning ...
Silver/polystyrene nanocomposites: Optical and thermal properties
(Wiley-Blackwell, Hoboken, 2012)
Nanocomposites consisted of different quantities of silver (Ag) nanoparticles incorporated in a polystyrene (PS) matrix have been prepared by solution mixing method. Transmission electron microscopy was applied to determine ...
Influence of the Organoclay Content on the Structure, Morphology, and Surface Related Properties of Novel Poly(dimethylsiloxane)-Based Polyurethane/Organoclay Nanocomposites
(American Chemical Society (ACS), 2017)
Novel poly(dimethylsiloxane)-based polyurethane nanocomposites (TPU-NCs) were synthesized using in situ polymerization with the nanoclay Cloisite 30B. Differential scanning calorimetry, thermogravimetric analysis, and ...
Protein subunit interfaces: a statistical analysis of hot spots in Sm proteins
(Springer, New York, 2010)
The distinguishing property of Sm protein associations is very high stability. In order to understand this property, we analyzed the interfaces and compared the properties of Sm protein interfaces with those of a test set, ...
Effects of organic additives on alumina coatings on stainless steel obtained by spray pyrolysis
(Elsevier, 2011)
Alumina coatings were obtained by deposition of boehmite sol, with added polyvinyl alcohol or polyethylene glycol, on stainless steel foil by spray pyrolysis method. Characterizations of coatings were performed by SEM, ...
Heteropentanuclear Oxalato-Bridged nd-4f (n=4, 5) Metal Complexes with NO Ligand: Synthesis, Crystal Structures, Aqueous Stability and Antiproliferative Activity
(Wiley-V C H Verlag Gmbh, Weinheim, 2015)
A series of heteropentanuclear oxalate-bridged Ru(NO)-Ln (4d-4f) metal complexes of the general formula (nBu(4)N)(5)[Ln{RuCl3(-ox)(NO)}(4)], where Ln=Y (2), Gd (3), Tb (4), Dy (5) and ox=oxalate anion, were obtained by ...
Formic acid oxidation on Pt-Au nanoparticles: Relation between the catalyst activity and the poisoning rate
(Elsevier, 2012)
Pt-Au nanoparticles supported on high area carbon were prepared by simultaneous reduction of Au and Pt precursors and by reduction of Pt precursor on already prepared Au nanoparticles. The first method produced a solid ...
Tunable invisibility cloaking by using isolated graphene-coated nanowires and dimers
(England : Nature Publishing Group, 2017)
We investigate, both theoretically and numerically, a graphene-coated nano-cylinder illuminated by a plane electromagnetic wave in the far-infrared range of frequencies. We have derived an analytical formula that enables ...
