The present work describes the synthesis of new benzanthrone dye-3-[4-(2-phenylethyl)piperazin-1-yl]-7H-benzo[de]anthracen-7-one by bromine atom nucleophilic substitution reaction. structure obtained derivative is characterized NMR spectroscopy, mass spectrometry, and X-ray diffraction analysis. photophysical properties target compound are investigated means UV-Vis fluorescence spectroscopy in ...

In this work we present an optical technique for characterizing sub-micrometric areas based on reflectivity of the light as a function of angle of incidence for the two pure polarizations s and p, covering a range of angles of incidence from -71.80° to 71.80° with a resolution of 0.1°. Circular areas with a diameter in the order of 600 nm can be characterized, and the spectra for the two polari...

The hexane extract of Curcuma aromatica, a plant belonging to the family Zingiberaceae was tested on 10 bacterial strains (clinical isolates and standard strains). Agar diffusion method was adopted for determining the antibacterial activity of the extract. The hexane extract was found to be active against all Gram-positive strains tested, but inactive against Gram-negative strains. The minimum ...

To investigate the phenolic and aroma composition of Malvazija istarska (Vitis vinifera L.) white wines produced by an unconventional technology comprising prolonged maceration followed by maturation in wooden barrels, representative samples were subjected to analysis by UV/Vis spectrometry, high-performance liquid chromatography, and gas chromatography-mass spectrometry. When compared to stand...

Situs Inversus, a rare congenital anatomical abnormality although is not directly related to Sudden Death. However, 3-5% of people with Situs Inversus have associated functional heart defect & 25% have an underlying condition i.e. Primary Ciliary Dyskinesis presenting as Kartagener's Syndrome; are prone to Sudden Death. Two cases of Situs Inversus on which medico-legal autopsy was conducted are...

The ability of firms to adapt to changing markets and technology is a fundamental topic both in strategic management and marketing literature. The focus of this paper is to study how firms adapt to their environments and create superior market orientation. We hypothesize specific relationships between market adaptation and market orientation. Moreover, we analyze the moderating effects of a fir...

The dynamics of retained and deactivating species in a SAPO-18 catalyst during the methanol-to-olefins reaction have been followed using combination ex-situ in-situ techniques differential integral reactors.The were analyzed extraction, FTIR UV-vis spectroscopies combined with online product analysis (gas chromatography mass spectrometry). composition extracted soluble was determined gas chroma...

Two new thiourea derivatives were synthesized through the reaction of photoactive aminohydroxybenzazoles and p-isothiocyanate benzoic acid via nucleophilic addition reaction. The compounds were characterized using high resolution mass spectrometry with eletrospray ionization (HRMS-ESI), Fourier transform infrared (FTIR), C and H nuclear magnetic resonance (NMR) spectroscopies. UV-Vis and steady...

We report on the tetraruthenium macrocycles Ru4-5 and -6 with a π-conjugated pyrene-appended 5,8-divinylquinoxaline ligand either isophthalate or thiophenyl-2,5-dicarboxylate linkers their charge-transfer salts formed by oxidation two equivalents of F4TCNQ. Both macrocyclic complexes were characterized NMR spectroscopy, mass spectrometry, cyclic square-wave voltammetry, IR, UV–vis–NIR, EPR spec...
