This paper presents a spectroscopic study on doping of Vanadyl pathalocyanine (VOPc) by [6,6]-phenyl C61 butyric acid methyl ester (PCBM). The films are characterized by UV/Vis/NIR spectroscopy. A drastic increase in the absorption coefficient has been observed with increasing dopant concentration. Optical properties of VOPc:PCBM films deposited by spin coating technique were studied in detail....

In the crystal structure of the title compound, [VO(C(7)H(6)ClN(2)O)(C(10)H(7)ClN(2)O(3))], the V(V) atom is N,O-chelated by the chloro-benzoyl-hydrazidate anion and O,N,O'-chelated by the (chloro-benzoyl-hydrazono)propionate dianion. The distorted octa-hedral trans-N(2)O(4) coordination geometry is completed by the vanadyl O atom. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds i...

In the title complex, [V(C(16)H(13)NO(3))(CH(3)O)O(CH(3)OH)], the V(V) atom is six-coordinated by a tridentate ligand derived from the condensation of salicyl-aldehyde and l-phenyl-alanine, a vanadyl O atom, a methano-late O atom and a methanol O atom, forming a distorted octa-hedral coordination geometry. In the crystal, inter-molecular O-H⋯O and C-H⋯O hydrogen bonds result in a two-dimensiona...

We report an alternative approach to enhance the optical and electrical performance of a vanadyl 2,9,16, 23-tetraphenoxy-29H,31H-phthalocyanine:poly(3hexylthiophene) (VOPcPhO:P3HT) blending system by integrating plasmonic spherical silver into an active layer of organic solar cells. Studies of the influence of the size distribution and optical properties of the silver nanoparticles were carried...

coverage improvement is one of the main problems in wireless sensor networks. given a finite number of sensors, improvement of the sensor deployment will provide sufficient sensor coverage and save cost of sensors for locating in grid points. for achieving good coverage, the sensors should be placed in adequate places. this paper uses the genetic and learning automata as intelligent methods for...

Adequate coverage is one of the main problems for distributed wireless sensor networks and The effectiveness of that highly depends on the sensor deployment scheme. Given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. In this paper, we apply fuzzy logic system to...

Vanadate is known to inhibit several phosphatases including Na+, K+-ATPase, alkaline phosphatase, and glyceraldehyde-3-P dehydrogenase. Inhibition presumably results because vanadium adopts a stable structure which resembles the transition state of phosphate during the reactions involving these enzymes. We performed experiments to further examine the effects of vanadate (VO3-4) on erythrocyte (...
