Local monitoring. Organic materials — new possibilities for ecological monitoring

Abstract

The gamma-ray blazar 1611+343 was observed with polarization VLBI mode at 5 GHz in February 1999. The total intensity (I) VLBI image of the source shows a core-jet structure. The jet bends eastward at ∼ 3 mas south of the core. Four components have been detected from results of fitting, with apparent speeds estimated at 6.7 ± 0.7, 2.5 ± 0.3, 4.5 ± 0.5 h −1 c for three jet components (taking H 0 = 100 h km s −1 Mpc −1 , q 0 = 0.5). The polarization (P ) VLBI image of 1611+343 displays the polarized configuration in the jet. The mechanism of the curved jet is discussed.

Synthesis and Properties of Extracomplexes of Tetrasubstitued Phthalocyanines

“…There is published information on the effective use of organic semiconductors, including phthalocyanines, as a material for sensitive elements of sensors for the determination of the composition of complicated gas mixtures [31,32]. Effects of various gases (H 2 S, NO 2 , and Cl 2 ) on variation of conduction of thin-film samples have been studied.…”
