In this study, benzophenone was introduced onto partially hydrolyzed poly(2-ethyl-2-oxazoline) (PEtOx-PEI) to prepare a poly(2-ethyl-2-oxazoline)-benzophenone (PEtOx-BP) copolymer, which was used to produce water stable nanofibers via aqueous electrospinning and photocrosslinking. Three differen...
Polymeric films were prepared based on chitosan and its blends with poly(2-ethyl-2-oxazoline) by casting from aqueous solutions. These materials were characterised using a number of physicochemical techniques, including Fourier-transform infrared spectroscopy, thermal gravimetric analysis, diffe...
Aromatic epoxides are causative factors for mutagenic and carcinogenic activity of polycyclic arenes. The 1,2- or 2,3-epoxy compounds are widely used to a considerable extent in the textile, plastics, pharmaceutical, cosmetics, detergent and photochemical industries. The FTIR and FT-Raman spectr...
(±)-2-Piperazinecarboxylic acid is prepared from N-carbethoxy-4-piperidone by α Schmidt rearrangement followed by bromation of the lactam; then α Favorskii rearrangement on the monobromolactam intermediate afforded the desired product.
In this study 2-(4-methoxyphenylamino)-2-oxoethyl methacrylate (MPAEMA) has been synthesized and characterized experimentally (FTIR, NMR). Theoretically, physical, electronic and vibrational properties of MPAEMA molecule have been investigated using density functional theory (DFT) calculations a...
This paper investigates the porphyrin de-aggregation in a set of guest-host films, prepared by spin coating, in a series of poly(n-alkyl methacrylate)s matrices. UV–Vis optical absorbance and steady-state photoluminescence spectroscopy in association with the fluorescence lifetime imaging techn...
Core-cross-linked micelles (CCM) functionalized at the core with covalently linked bis(p-methoxyphenyl) phenylphosphine (BMOPPP) ligands have been synthesized by a three-step one-pot radical polymerization in emulsion, using the polymerization-induced self-assembly (PISA) strategy and reversible...
Picosecond population relaxation time of cresyl violet in methanol was measured by phase-conjugation type time-delayed four- wave mixing using incoherent light (TDFWM-IL). The excited state population relaxation time T1 is about 157 ps. Another important dynamical process, absorption recovery, w...
A homogeneous stopped-flow fluoroimmunoassay method based on the use of Cresyl Violet as label is described for the first time and applied to the determination of the pesticide 2,4,5-trichlorophenoxyacetic acid (2,4,5-T). The tracer showed an increase in its fluorescence intensity when reacted w...
The chemical and photophysical behavior of cresyl violet perchlorate was studied in aqueous, aqueous micellar and organic solutions. In aqueous micellar solutions the fluorescence quantum yield of cresyl violet increases in sodium dodecylsulfate (SDS), whereas a dramatic decrease is observed in ...
Cresyl violet is widely used by neurobiologists to visualize Nissl substance in bright-field microscopy. Here we describe a method for using this dye as a red fluorescent Nissl stain. Unlike the bright-field staining technique, fluorescent cresyl is compatible with other fluorescent dyes and tra...
The dynamic interaction of Cresyl Violet (CV) in different micellar systems has been demonstrated in single molecular level by FCS studies. The SDS micelle entrapped CV efficiently detected Cu2+ ions in solution with a limit of detection (LOD) of 70 nM, which is further substantiated with the gr...
A new type of magnetoliposomes (MLs), containing hydrophobic magnetic-gold nanoparticles and the long wavelength fluorophore cresyl violet, has been used for the determination of coenzyme Q10 (CoQ10). MLs were concentrated just before the detector, using a flow system and an external electromagn...
In this study, solvents polarity effects on nonlinear properties of Crysel violet acetate (CVA) dye were investigated by Z-scan method. Nonlinear parameters (absorption coefficient and refractive index) for CVA dye in solvent media were obtained using experimental setup. The obtained experimenta...
Here we present the production, characterization and in-vivo assessment of cresyl violet-loaded biodegradable PLGA nano/microparticles (CV-NP and CV-MP). We demonstrate that the beneficial spectral characteristics of cresyl violet make it suitable as a tracer for particle-based drug delivery usi...
A one-pot multi-component reaction of aldehydes, enolizable ketones or 1,3-dicarbonyls, acetonitrile/benzonitrile, and acetyl chloride is described for the preparation of β-acetamido carbonyl compounds using FeCl3·6H2O as a mild, inexpensive, and highly efficient catalyst. The effect of substr...
A series of novel acetamido derivatives containing N-pyridylpyrazole carboxamides was designed and synthesized by increasing the amide bridge of chlorantraniliprole using acetamido moieties and introducing different aryl substitutions. The target compounds were characterized by 1H NMR, 13C NMR, ...
The O-polysaccharide was isolated from the lipopolysaccharide of a marine bacterium Pseudomonas glareae KMM 9500T and studied by chemical methods along with 1D and 2D 1H and 13C NMR spectroscopy including 1H,1H-TOCSY, 1H,1H-COSY, 1H,1H-ROESY, 1H,13C-HSQC and 1H,13C-HMBC experiments. The O-polysa...
Advanced oxidation of atrazine (ATZ) via electrolysis and ozonation separately and in combination was studied in the presence of concentrated chloride and bromide electrolytes at pH 7. Ozone (O3) was bubbled at a rate of 0.3 L/min into a batch electrolysis reactor utilizing a boron-doped diamond...
The multicomponent condensation of an aryl aldehyde, acetyl chloride, acetonitrile, and enolizable ketone as one-pot synthesis of β-acetamido ketones in high yields was investigated using commercial, non-corrosive, and environmentally benign Keggin and Wells-Dawson heteropolyacid catalysts. The...
