Three benzimidazole-based organic dyes, possessing the same triphenylamine donors and cyanoacrylic acid acceptors with the bithiophene π-bridges combined in different nuclear positions of benzimidazole, were investigated in the utility of dye-sensitizer solar cells. The structure, molecular orbital and energy, absorption spectra and some important parameters (such as light harvesting efficiency...

This study aims to describe the pattern of legal relationships that occur in financing activities through qardhul hasan Sharia Savings and Loans Cooperative (KSPPS) located Karanganyar Regency, based on doctrinal (normative) approach method which prioritizes secondary data analysis deductive logic. Based results research discussion conducted, it was found norms used regulate subjects, objects, ...

Soil genesis, physico-chemical properties and tea yield were investigated along different hillslope positions in the major tea cultivation area of Iran, i.e. Lahijan, Gilan Province. Land suitability was also determined for the tea production in this hilly region. Four different slope positions i.e., summit, shoulder, backslope and toeslope were sampled on three slope aspects following the prof...

Abstract Three new ethyltin complexes containing ferrocenecarboxylate, Et 2 Sn(OC(O)Fc) ( 1 ), [(Et SnOC(O)Fc) O] and [EtSn(O)OC(O)Fc] 6 3 ) (Fc = C 5 H FeC 4 have been synthesized by the reaction of diethyltin dichloride with ferrocenecarboxylic acid in presence potassium hydroxide characterized means elemental analysis, FT-IR, NMR spectroscopy, X-ray single crystal diffraction. In solid state...

We report the use of a tunable differential interferometer for optical tomography. This interferometer has several advantages over other methods for phase measurements in optical tomography, including good stability, variable sensitivity, and the elimination of fringe ambiguity. Quantitative images of the gas concentrations in subsonic jets of methane and oxygen issuing into air are presented, ...

1-Carboxymethyl-3-methylimidazolium chloride {[cmmim]Cl} is utilized as a highly efficient and reusable catalyst for the synthesis of bis(indolyl)methanes by the condensation reaction of indole with arylaldehydes under solvent-free conditions at room temperature. In summary, the presented method have several advantages including simplicity, low cost, generality, efficiency, clean reaction profi...

This paper develops a model of optimal government debt maturity in which the government cannot issue state-contingent bonds and cannot commit to fiscal policy. If the government can perfectly commit, it fully insulates the economy against government spending shocks by purchasing short-term assets and issuing long-term debt. These positions are quantitatively very large relative to GDP and do no...
