New inorganic-organic hybrid: Synthesis and structural characterization of an alumino(oxalato)phosphate
(Amer Chemical Soc, Washington, 2003)
A new 3-D alumino(oxalato)phosphate, [H3NCH(CH3)CH2NH3](2)[Al4P6O20(OH)(4)(C2O4)(H2O)], consists of aluminophosphate layers which are pillared by oxalate anions. It contains a hybrid 12-membered channel where guest species, ...
Sorption properties of TEMPO-oxidized natural and man-made cellulose fibers
(Elsevier Sci Ltd, Oxford, 2009)
Cotton and lyocell fibers were oxidized with sodium hypochlorite and catalytic amount of sodium bromide and 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO), under various conditions. Water-insoluble fractions, collected ...
Preparation and characterization of iron(III) phosphate-oxalate using 1,2-diaminopropane as the structure-directing agent
(Elsevier, Amsterdam, 2002)
Iron(III) phosphate-oxalate (FePO-DAP) crystallizes from a clear solution containing 1,2-diaminopropane (DAP) and oxalic acid at 120 degreesC under hydrothermal conditions. Doubly protonated DAP is present inside a large ...
Spectrophotometric study of the anodic corrosion of Ti/RuO2 electrode in acid sulfate solution
(Elsevier Ltd., 2004)
Electrochemical properties of RuO2-based electrode, particularly the oxygen evolution and anodic dissolution of RuO2 have been investigated in 0.5 mol dm-3 H2SO4 solution by means of polarization measurements and product ...
Kinetic study of the hydrogen oxidation reaction on sub-stoichiometric titanium oxide-supported platinum electrocatalyst in acid solution
(Elsevier, 2009)
The kinetics and mechanism of the hydrogen oxidation reaction were studied in 0.5 mol dm-3 HClO4 solution on an electrode based on titanium oxide with Magneli phase structure-supported platinum electrocatalyst applied on ...
Electrodeposition of Ni-Mo alloy coatings and their characterization as cathodes for hydrogen evolution in sodium hydroxide solution
(Elsevier, 2008)
The hydrogen evolution reaction on the electrodeposited Ni-Mo alloy coatings, as well as their electrochemical properties in the NaOH solutions, have been investigated by the polarization measurements, cyclic voltammetry ...
High-throughput diversity and functionality analysis of the gastrointestinal tract microbiota
(Bmj Publishing Group, London, 2008)
The human gastrointestinal (GI) tract microbiota plays a pivotal role in our health. For more than a decade a major input for describing the diversity of the GI tract microbiota has been derived from the application of ...
Kinetics of sunflower oil methanolysis catalyzed by calcium oxide
(Elsevier, 2009)
The methanolysis of sunflower oil was studied in the presence of CaO previously calcined at various temperatures and the optimal temperature for CaO calcination was determined. The sigmoidal process kinetics was explained ...
Formation of nanocrystalline transition-metal ferrites inside a silica matrix
(Wiley, Hoboken, 2002)
Nanocrystalline transition-metal ferrites were synthesized inside an amorphous silica matrix by the sol-gel method. The formation of spinel ferrites began above 400degreesC, giving fine particles of about 10 nm at 800degreesC. ...
Optimization of processing parameters for preparation of LaNiO3 thin films from the citrate precursors
(Elsevier Sci Ltd, Oxford, 2007)
Lanthanum nickel oxide (LaNiO3) is an electrically conductive ceramics, which has a potential use as electrode for ferroelectric thin films, multilayer actuators and many other electronic devices. In this work, LaNiO3 thin ...
