(E)-2-{[4-(dimethylamino)benzylidene]amino}-5-nitrophenol
(
International Union of Crystallography
, 2014 , Article)
The title Schiff base compound, C15H15N 3O3, crystallizes with two molecules (A and B) in the asymmetric unit. Each molecule adopts an E conformation around the C= N imine bond. The two molecules have minor differences in ...
High-frequency viscoelastic measurements of fluids based on microcantilever sensing: New modeling and experimental issues
(
Elsevier
, 2013 , Article)
In general, microrheology is carried out using active or passive particle-tracking techniques. In the present paper, a novel technique based on the out-of-plane bending vibrations of a microcantilever beam immersed into a ...
Catalytic C-H oxidations by nonheme mononuclear Fe(II) complexes of two pentadentate ligands: Evidence for an Fe(IV) oxo intermediate
(
Elsevier
, 2016 , Article)
The oxidation reactions of alkanes with hydrogen peroxide and peracids (peracetic acid (PAA) and m-chloroperoxybenzoic acid (mCPBA)) catalysed by two Fe(II) complexes of pentadentate {N5}-donor ligands have been investigated. ...
Adsorption of 2, 4-dichlorophenoxyacetic acid onto date seeds activated carbon: Equilibrium, kinetic and thermodynamic studies
(2012 , Article)
Adsorption isotherm and kinetics of 2,4-dichlorophenoxyacetic acid (2,4-D) herbicide on activated carbon prepared from Barhi date seeds were determined from batch tests. The effects of contact time, initial herbicide ...
Batch study for herbicide bentazon adsorption onto palm oil fronds activated carbon
(2012 , Article)
The adsorption of herbicide bentazon from aqueous solution onto activated carbon derived from palm oil fronds (PFAC) was investigated through batch study. The effects of both; initial concentration of the bentazon (ranging ...
Synchronous spectrofluorimetric study of the supramolecular host–guest interaction of β-cyclodextrin with propranolol: A comparative study
(
Elsevier
, 2015 , Article)
The objective of this work is to assess the use of constant-wavelength synchronous fluorescence spectroscopy (SFS) in comparison to conventional fluorescence spectroscopy (CFS) for the investigation of the supramolecular ...
Conducting polyaniline nanorods doped with aromatic carboxyl chain end functionalized polystyrene
(
Elsevier
, 2015 , Article)
The preparation of new conducting polyaniline (PANI) derivatives with different nanostructures is described. PANI derivatives doped with aromatic carboxyl chain end functionalized polystyrene derivatives of different number ...
Nonheme Fe(IV) Oxo Complexes of Two New Pentadentate Ligands and Their Hydrogen-Atom and Oxygen-Atom Transfer Reactions
(
American Chemical Society (ACS)
, 2015 , Article)
Two new pentadentate {N5} donor ligands based on the N4Py (N4Py = N,N-bis(2-pyridylmethyl)-N-bis(2-pyridyl)methylamine) framework have been synthesized, viz. [N-(1-methyl-2-benzimidazolyl)methyl-N-(2-pyridyl)methyl-N-(bi ...
Synthesis, spectroscopic and thermal studies of charge-transfer molecular complexes formed in the reaction of 1,4-bis (3-aminopropyl) piperazine with σ- and π acceptors
(
Elsevier
, 2012 , Article)
Abstract In the present study, solid charge-transfer (CT) molecular complexes formed in the reaction of the electron donor 1,4-bis (3-aminopropyl) piperazine (APPIP) with the σ-electron acceptor iodine and π-acceptors ...
