novel analytical technique has been suggested for determination of Pb usingformation of PbH4(g) by chemical reduction and its subsequent spectrophotometric measurement in IR region, using the peak at 1821.4 cm(-1). The range of measurements is 1.0-30.0 mg l(-1) using a sample of 1.0 ml in flow injection mode. The 3 sigma limit of detection is 0.28 mg l(-1). The method has been applied to standard reference materials of Waste Water, EU-L-1, lead-base bearing metal 53e and Soil/Sediment #4 as well as soil samples collected from heavy traffic areas in Ankara.

Quantitative structure-activity relationship study of some 7-substituted theophyllines
Türker, Burhan Lemi; Akgun, H; Balkan, A (1998-01-01)
Some novel 7-substituted theophylline derivatives have been investigated for quantitative structure-activity relationship (QSAR). For this purpose, their bronchodilatory activities (in vitro), which were examined by the inhibition of acetylcholine induced contraction in tracheae isolated from guinea pigs, have been correlated with various quantum chemical and physicochemical parameters.
Synthesis and electro-optical properties of new conjugated hybrid polymers based on furan and fluorene units
Gunes, Arzu; CİHANER, ATİLLA; Önal, Ahmet Muhtar (2013-02-01)
A novel series of hybrid monomers containing furan and fluorene units, namely 2-(2-(furan-2-yl)-9H-fluoren-7-yl)furan (FFF), 2,7-di(furan-2-yl)-9H-fluoren-9-one (FOF) and 2-(2-(furan-2-yl)-9,9-dihexyl-9H-fluoren-7-yl)furan (FHF), was synthesized and their electrochemical polymerization was achieved via potential cycling. Optical and electrochemical properties of the polymers, poly(2-(2-(furan-2-yl)9H-fluoren-7-yl)furan (PFFF), poly(2,7-di(furan-2-yl)-9H-fluoren-9-one) (PFOF) and poly(2-(2-(furan2-yl)-9,9-di...
Tip enhanced Raman scattering with adiabatic plasmon focusing tips.
Bek, Alpan; DAS, G; Di, Fabrizio; LAZZARINO, M (Elsevier BV, 2011-06-01)
Tip-Enhanced Raman spectroscopy (TERS) is a promising microscopy technique which combines, in principle, outstanding spatial resolution with a detailed chemical analysis of the sample. However, as yet, it is not routinely used although an increasing number of research groups are becoming more actively involved in the field. Among the several reasons which can explain the relatively low usage of TERS, the lack of reproducibility of tips as field enhancers is probably the most critical. Here we propose and de...
Application of silicalite-modified electrode for the development of sucrose biosensor with improved characteristics
Pyeshkova, Viktoriya M.; Dudchenko, Oleksandr Y.; Soldatkin, Oleksandr O.; Kasap, Berna Ozansoy; Lagarde, Florence; Akata Kurç, Burcu; Dzyadevych, Sergei V. (2015-03-27)
The application of silicalite for improvement of working characteristics of conductometric enzyme biosensors for determination of sucrose was studied in this research. Biosensors based on different types of silicalite-modified electrodes were studied and compared according to their analytical characteristics. Polyethylenimine/glutaraldehyde/silicalite-modified biosensors showed higher sensitivity compared with others type of biosensors. Moreover, the polyethylenimine/glutaraldehyde/silicalite sucrose biosen...
Phase-field modeling of vapor bubble growth in a microchannel
Jafari, R.; Okutucu Özyurt, Hanife Tuba (2015-09-01)
Anumerical model based on Cahn–Hilliard phase-field method is introduced for thefirst time in the literature to investigate the hydrodynamics and heat transfercharacteristics of a vaporized elongated bubble in a rectangular microchannel. In thesimulations, the initially nucleated bubble starts growing as it comes in contact withsuperheated water. The effects of the water inlet velocity and the bubble contact angleon the temporal evolution of the average hea...
