CoO/Al-doped ZnO (AZO) multilayers exhibit ferromagnetism up to ~300 K. The magnetic behavior oscillates with odd vs even number of Co layers in the insulating antiferromagnetic CoO and (separately) with the thickness of the AZO layers and vanishes if AZO is replaced by intrinsic ZnO. Magnetization is due to uncompensated (111) ferromagnetic planes of insulating CoO for odd numbers of atomic pl...
Polycaprolactone (PCL) nanofibers incorporating azo dye/γ-cyclodextrin inclusion complex (Azo/γ-CD-IC) were successfully produced. The characteristics of the Azo/γ-CD-IC and PCL/Azo/γ-CD-IC investigated by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) thermogravimetric analysis (TGA). Based on SEM prepared nanofiber has a smooth surface with size diameter below 500 nm....
Molecular structures of 4-(((4-methoxyphenyl)amino)methyl)-N,N-dimethylaniline and 2-methoxy-5-((phenylamino)methyl)phenol synthesized via Schiff bases reduction route are reported. The compounds consist asymmetric units C16H20N2O (1) C14H15NO2 (2) in orthorhombic monoclinic crystal systems, respectively. Compound 1 intermolecular C11—H11···N2 hydrogen bonding with C11···N21 = 3.463(4) Å. hydro...
Three triorganotin(IV) complexes of composition R3SnLH (R = Me, Bu and Ph and LH = 2-[(E)-2-(4-hydroxy-3,5-dimethylphenyl)-1-diazenyl]benzoate) have been synthesized and characterized by 1H-,13C-, 119SnNMR, and IR spectroscopic techniques in combination with elemental analysis. The crystal structures of the carboxylate ligand HO2CC6H4N=N(C6H2-4-OH-3,5-(CH3)2)-o in its neutral form and three tri...
Twenty-two azo dyes were used to study the influence of substituents on azo dye biodegradability and to explore the possibility of enhancing the biodegradabilities of azo dyes without affecting their properties as dyes by changing their chemical structures. Streptomyces spp. and Phanerochaete chrysosporium were used in the study. None of the actinomycetes (Streptomyces rochei A10, Streptomyces ...
In this paper we present six select mesomorphic azo compounds distinguished by the presence of diverse substituents on a central benzene nucleus. All the synthesized compounds exhibit enantiotropic mesophases. The mesomorphic properties of the substituted compounds were compared with those of the unsubstituted parent compound to evaluate the effect of the nature and position of the substituents...
a bacterial strain (strain ps) was isolated from the textile effluents carrying serilene black bnfs® (c.i. disp. blk. mix) disperse dye. the isolate was able to decolorize the dye without the need for any exogenous carbon source. full sequencing of its 16s rrna indicated that bacillus sp strain ps is related to bacillus cereus groups. silica- gel-thin layer chromatography of serilene black dye...
BACKGROUND A series of recently reported phenolic azo dyes 7a-e were prepared by coupling the thienyl diazonium sulfate of 3-Amino-4H-benzo[f]thieno[3,4-c](2H)chromen-4-one with selected diversely substituted phenolic and naphtholic derivatives. These compounds were evaluated for their antibacterial and antifungal activities. Furthermore their voltammetric behavior was compared at a glassy carb...
BACKGROUND AND OBJECTIVES Acceptable noise level (ANL) is a measure of the maximum background noise level (BNL) that a person is willing to tolerate while following a target story. Although researchers have used various sources of target sound in ANL measures, a limited type of background noise has been used. Extending the previous study of Gordon-Hickey & Moore (2007), the current study determ...
Stimuli-responsive self-assembly is playing an increasingly important role in emerging applications, ranging from smart materials to biosensors. However, obtaining essential information for further development, such as molecular arrangement and interaction, is still experimentally challenging. A molecular-level understanding of the stimuli-responsive self-assembly is needed. Azobenzene-containi...
