Iron oxide (Fe2O3) is widely used as a catalyst, pigment and gas sensitive material.  In this article, α-Fe2O3 nano-rods were first synthesized via a simple chemical method using iron(III) nitrate 9- hydrate (Fe(NO3)3.9H2O) as precursor. XRD pattern showed that the iron oxide nanoparticles exhibited alpha-Fe2O3 (hematite) structure in nanocrystals. The single-phase α- Fe2O3 nano-rods were prepa...

In this paper, the structure of a new 16-membered macrocyclic Schiff base compound N,N′-(3,3′-dimethoxy-2,2′-(propane-1,3-diyldioxy)dibenzylidene)propane-1,3-diamine, C22H26N2O4 (1), derived from 1,3-propanediamine and 3,3′-dimethoxy-2,2′-(propane-1,3-diyldioxy)dibenzaldehyde has been studied by single crystal X-ray diffraction, DFT calculations at B3LYP/6-31G** and FT-IR spectroscopy. The titl...

Lowest energy spectrum of the $^{12}$C nucleus is analyzed in 3$\alpha$ cluster model with a deep $\alpha\alpha$-potential Buck, Friedrich and Wheatley Pauli forbidden states $S$ $D$ waves. The direct orthogonalization method applied for elimination 3$\alpha$-Pauli states. effects possible first order quantum phase transition are shown lowest $^{12}$C($0_1^+)$ $^{12}$C($2_1^+)$ from weakly boun...

Body's iterative force-field computer program has been used to calculate strain energies in cyclooctanone (I). 348 MHZ 1H NMR spectra of (I) have been investigated over the temperature range of 25° to -160°C. Two conformation processes affect the 1H NMR spectrum of (I). Iterative force-field calculations on the conformations and conformational interconversion paths of ...

We consider semi-infinite Jacobi matrices with discrete spectrum. prove that a operator can be uniquely recovered from one spectrum and subsets of another norming constants c...

This paper presents a novel concept of active radio spectrum profiling f or C ognitive R adio ( CR) networks using evolutionary hypernetworks. Spectrum profiling enables cognitive radio nodes to abstract and predict usable spectrum opportunities in pre-defined P rimary U sers ( PU) c hannels. T he P U c hannels a re actively monitored through spectrum sensing and the resulting binary time serie...

The main goal of this research work was to detect the different Cu mineralized zones in the Sungun porphyry deposit in NW Iran using the Spectrum-Volume (S-V) fractal modeling based on the sub-surface data for this deposit. This operation was carried out on an estimated Cu block model based on a Fast Fourier Transformation (FFT) using the C++ and MATLAB programing. The S-V log-log plot was gene...

We compute the c ¯ b spectrum from a first principle Salpeter equation obtained in a preceding paper. For comparison we report also the heavy-light quarko-nium spectrum and the hyperfine separations previously presented only in a graphical form. Notice that all results are parameter free. The experimental observation of the B + c meson [1] has arisen new theoretical interest for the properties ...

It used to be difficult to quantitate aerobic metabolic flux in mammalian tissue samples, especially in the multiple samples necessary to reveal spatial heterogeneity of energy turnover. Here we discuss a strategy to infuse carbon-13 labeled substrates for aerobic metabolism and obtain myocardial tissue samples after 57 min, before the isotopic steady state is reached. The multiplet structure i...
