Treatment of Soil-Washing Effluents Polluted with Herbicide Oxyfluorfen by Combined Biosorption-Electrolysis
(
American Chemical Society
, 2017 , Article)
The treatment of soil-washing effluents polluted with herbicide oxyfluorfen is studied using a combined process consisting of biosorption and electrolysis. Results show that oxyfluorfen is very efficiently removed from ...
Iron and cobalt salicylaldimine complexes as catalysts for epoxide and carbon dioxide coupling: effects of substituents on catalytic activity
(
Springer International Publishing
, 2017 , Article)
The synthesis and characterization of substituted ONNO-donor salen-type Schiff base complexes of general formula [MIII(L)Cl] (L�=�Schiff base ligand, M�=�Fe, Co) is reported. The complexes have been applied as catalysts ...
A Cross-Coupling Approach to Amide Bond Formation from Esters
(
American Chemical Society
, 2017 , Article)
A palladium-catalyzed cross-coupling between aryl esters and anilines is reported, enabling access to diverse amides. The reaction takes place via activation of the C-O bond by oxidative addition with a Pd-NHC complex, ...
Synthesis and Physicochemical Studies of Perovskite Manganite La0.8Ca0.2Nn1−xCoxO3 (0 ≤ x ≤ 0.3)
(
The Korean Magnetics Society
, 2017 , Article)
The physicochemical properties of La0.8Ca0.2Mn1−xCoxO3 nanopowders as a function of Co content (x) have
been investigated. La0.8Ca0.2Mn1−xCoxO3 nanopowders were synthesized by sol-gel method and morphologically
and ...
Synthesis and characterization of electrically conductive poly(aniline-co-3-bromoaniline) nanocomposites
(
Springer New York LLC
, 2017 , Article)
Poly(aniline-co-3-bromoaniline) copolymers with varying compositions of the monomers have been prepared in this work by copolymerization of aniline and 3-bromoaniline using ammonium persulphate as oxidant. Structure and ...
Optical modulator based on silicon nanowires racetrack resonator
(
SPIE
, 2018 , Conference Paper)
An optical modulator based on the racetrack resonator configuration is introduced.The structure of the resonator modulator is built from silicon nanowires on silica.The cladding and voids between the silicon nanowires are ...
Intramolecular versus intermolecular hydrogen bonds in a novel conjugated dimethylamino-benzylidene-amino-2-naphthoic acid Schiff base
(
Springer Verlag
, 2017 , Article)
A new compound based on the D-π-A concept, where D = dimethylamino-phenyl and A = naphthoic acid, separated by an imine motif, was designed, synthesized and characterized. The spectral, energetics, and structural characteristics ...
Tuning the electrical properties of polyaniline by copolymerization with o-bromoaniline
(
World Scientific Publishing Co. Pte Ltd
, 2017 , Article)
Polyaniline, poly(o-bromoaniline) and poly(aniline-co-o-bromoaniline)s have been prepared by chemical oxidative polymerization methods. A series of poly(aniline-co-o-bromoaniline) derivatives has been prepared by the ...
Amplitude modulation in infrared metamaterial absorbers based on electro-optically tunable conducting oxides
(
Springer Verlag
, 2018 , Article)
A class of electro-optically tunable metamaterial absorbers is designed and theoretically investigated in the infrared regime towards realizing free-space amplitude modulators. The spacer between a subwavelength metallic ...
Polymerization of 3-cyanopropyl (triethoxy) silane: A kinetic study using gas chromatography
(
John Wiley and SonsInc.
, 2018 , Article)
Gas chromatography (GC) was used to study the kinetics of the 3-cyanopropyl triethoxysilane (CTES) polymerization. The reaction is a consecutive complex reaction that depends mainly on the kinetics of the first hydrolyzed ...
