A conductometric sensor based on screen-printed interdigital gold electrodes on glass substrate coated with molecularly imprinted polyurethane layers was fabricated to detect polycyclic aromatic hydrocarbons (PAHs) in water. The results prove that screen-printed interdigital electrodes are very suitable transducers to fabricate low-cost sensor systems for measuring change in resistance of PAH-i...

The synthesis and investigation of new Hetero Cyclic Dithicarbamate ligand and its solid metal complexes derived from 4-Amino-1,2,4triazole(ATAZ) and 2-Amino 4-Hydroxy-6-methyl pyrimidine (AHPY) by using different synthetic methods. The derived colored complexes are Au (III) and Ru (III) with above mentioned ligands. The structures and bio cancer activity were elucidated by different type of st...

Polymerization of β-phenyl glutaconic diethyl ester (GE) with various diamines (DA) at 1:2 molar ratios in 1,4dioxane solvent was carried out at reflux temperature. The resultant amino terminated unsaturated oligomers (ATUP) were characterized by elemental analysis, number of terminal amino groups, IR spectral studies, number average molecular weight estimated by non-aqueous conductometric titr...

phase sensitive detector described here has two principal applications: a- to produce a d.c out put proportional to- the amplitude of an incoming a,c signal and indicate, by the outut polarity, the phase of the signal with respect to an internal reference. b- to detect the presence of a signal of known phase and frequency which would otherwise be lost in «background noise» and to measure its am...

in this paper a new algorithm is presented for coherent radar detection of targets, when distribution of the interference (clutter and noise) is non-gaussian. the neyman-pearson criterion is used for optimal detection and several successive received samples from a radar range cell are used for detection in the same cell. on the basis of recent empirical evidences, the interference distribution ...

In this work, we present the experimental study of nanofluids’ electrophysical characteristics concentration dependencies specific behavior (nanoparticles Al2O3, ZnO and Fe2O3 in isopropyl alcohol) at low concentrations. The values a conductivity, electrical capacitance dielectric permittivity are measured depending on suspended particles’ for concentrated nanofluids far from percolation thresh...
