A series of 5-dialkyl(aryl)aminomethyl-8-hydroxyquinoline dansylates were synthesized and their fluoroionophoric properties toward representative alkali ions, alkaline earth ions and transition metal ions were investigated. Among the selected ions, Fe3+ caused considerable quenching of the fluorescence, while Cr3+ caused quenching to some extent. The absence of any significant fluorescence quen...

A simple and efficient method using reduced amounts of solvents for the determination polycyclic aromatic sulfur heterocycles (PASHs) in aqueous matrices from a lagoon leachate solid waste petrochemical industry is proposed. The target analytes were previously concentrated disposable pipette extraction (DPX) technique applying gas chromatography-mass spectrometry (GC-MS) analysis. In this innov...

We demonstrate a hybrid inorganic/organic light-emitting device composed of a CdSe/ZnS core/shell semiconductor quantum-dot emissive layer sandwiched between p-type NiO and tris-(8-hydroxyquinoline) aluminum (Alq3), as hole and electron transporting layers, respectively. A maximum external electroluminescence quantum efficiency of 0.18% is achieved by tuning the resistivity of the NiO layer to ...

Various genotoxic textile dyes, xenobiotics, substrates (10 µM) and agrochemicals (100 µg/ml) were tested for enhancement of alkalophilic laccase activity in γ-proteobacterium JB. Neutral Red, Indigo Carmine, Naphthol Base Bordears and Sulphast Ruby dyes increased the activity by 3.7, 2.7, 2.6 and 2.3 fold respectively. Xenobiotics/substrates like p-toluidine, 8-hydroxyquinoline and anthracine ...

The primary processing method of coffee plays a crucial role in determining its flavor profile. In this study, roasted beans were subjected to three methods, i.e., natural (SC), washed (WC), and honey (MC), that analyzed by LC-MS/MS GC-MS metabolomics. Additionally, sensory evaluation was conducted the Specialty Coffee Association America (SCAA) assess characteristics. results showed 2642 non-v...

Lilium cut flowers have commercial importance and extending their vase life is vital. An increase in the quality quantity can directly viability price realization of commercially important like lilium. Shelf lilium flower influenced by using different preservative chemicals sucrose added solution. Such an extension be achieved via chemical treatment. The trial was carried out to examine effect ...

Various azido-ubiquinone derivatives were synthesized and characterized. 3-Azido-2-methyl-5-methoxy-6-(3,7-dimethyloctyl)-1,4-benzoquinone was found to be suitable for the study of specific interaction between ubiquinone (Q) and protein. It was synthesized with high specific radioactivity and used to identify the Q-binding proteins in purified ubiquinol-cytochrome c reductase. This azido-Q deri...
