Z. Naturforsch. 2009, 64b, 487 – 490; received February 20, 2009 The title compound has been synthesized under 4 GPa and at 500 ◦C from Na2O and MnO as starting materials. Rietveld refinement of the X-ray powder pattern indicates that Na6MnO4 is isostructural to Na6ZnO4 and thus is representing the second manifestation of an “isolated” [MnO4]6− anion after Na14Mn2O9. The compound crystallizes i...

inoculation of phosphate-solubilizing microorganisms along with rock phosphate is known to enhance the available p from soil. the success of such solubilization is largely dependent on the ability of the inoculant strain to survive under adverse environmental conditions. in this context, liquid inoculants are gaining importance and are becoming popular with longer shelf-life. in the present inv...

abstract: this paper is the first study on the impact of ambient temperature on the electrical characteristics and high frequency performances of double gate armchair graphene nanoribbon field effect transistor (gnrfet). the results illustrate that the gnrfet under high temperature (ht-gnrfet) has the highest cut-off frequency, lowest sub-threshold swing, lowest intrinsic delay and power delay ...

background and objectives: pulsed electric field (pef) is a novel emerging technology which is believed to have the potential to substitute conventional thermal pasteurization (htst). in the current study pef was compared with htst based on microbial inactivation and quality attributes. materials and methods: juice was prepared by extracting it from semirum apples. they were chilled to 4ºc over...

Electrical resistivity (ER) is a main parameter in the melting processes of glasses. However, its measurement is difficult at high temperatures. In this study the electrical resistivity of different cordierite glass samples in the molten state was measured in the temperature range of 1100˚C to 1550 ˚C using the two-wire method. It was attempted to decrease the electrical resistivity of the glas...
