Seven symmetrical azomethines with two imine groups (HC=N) were synthesized by condensation of the benzene-1,4-dicarboxaldehyde with five amines (first group: A1-A5) and of the 2,5-thiophenedicarboxaldehyde with two amines (second group: AT1-AT2). Additionally, two unsymmetrical azomethines were obtained by a two step condensation of benzene-1,4-dicarboxaldehyde with pyren-1-amine (1 step) (abb...

Neutronirradiation effects on optical absorption of solid-state nuclear track detector, CR-39 was studied for the various fluences ranging from 2.38x106 to 2.7x108 n/cm by ultraviolet-visible (UVVis) spectroscopy. The optical absorption spectra in the wavelength range of 200-700nm were recorded for the pristine and the neutron irradiated samples in the above fluence range. The UV-visible spectr...

Many attempts have been made to derive elemental abundances of the lunar surface from multispectral images. A method to predict Fe abundance based on Clementine UVVIS data is presented in [1]. A refined method which also addresses the TiO2 abundance is provided in [2], demonstrating that in spite of issues posed by soil maturity, grain size, mineral content, topographic shading, and glass conte...

Introduction: This contribution explores the mapping of spectral parameters of lunar features using the Clementine UVVIS+NIR data set covering the wavelength range between 415 and 2000 nm [1]. The extracted spectral features are the minimum and depth of the principal absorption trough near 1000 nm and the corresponding values of secondary absorption features present at higher wavelengths, as we...

This research has studied equilibrium adsorption isotherms of Ketotifen on carbon nanotube. And also results of experiments through Freundlich,Temkin and Langmuir models have been studied and it has found different parameters of these models for carbon nano-tube adsorbent. According to the error rate for each model, we obtained a good agreement between these data which it showed the best agreem...

Three fluorescent asymmetric bis-urea receptors (L1-L3) have been synthesised. The binding properties of L1-L3 towards different anions (fluoride, acetate, hydrogencarbonate, dihydrogen phosphate, and hydrogen pyrophosphate HPpi3-) have been studied by means of 1H-NMR, UVVis and fluorescence spectroscopies, single crystal X-ray diffraction, and theoretical calculations. In particular, a remarka...

Background: The Clementine mission provided the first high resolution mul-tispectral image data set of the far side of the Moon. While near side surface morphological units have been studied extensively from earth based spectral measurements, this is the first opportunity to examine the compositional properties of far side areas. Moscoviense is one of the prominent large impact basins on the lu...
