“…The sharp peak at around 3448 cm À1 is correlated with the hydroxy bond (O À H) formed during the activation process. [36] Electron microscopy such as SEM is a precise instrumentation method for the direct observation of non-material samples. [37] AFM is also used to study the topography of the elements at micro and nano scales.…”

Various 2-arylbenzimidazoles were synthesized from phenylenediamines and aromatic aldehydes via a one-step process in the presence of a catalytic amount of a cobalt-salen complex supported on activated carbon [CoxO-CoA C H T U N G T R E N N U N G (salen) 11] at room temperature. The salient features of this method include mild conditions, short reaction times, high yields, easy purification, recyclable catalyst, largescale synthesis and simple procedure. The reactions were performed in ethanol and the catalyst could be reused for several cycles without a decrease in activity. The heterogeneous catalyst was characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic forced microscopy (AFM), thermogravimetric (TG) methods for analysis of nitrogen adsorption and FT-IR spectroscopy. Leaching experiments showed that the catalyst is most strongly anchored to the activated support after 10 cycles of reuse.

“…Therefore there is a possibility that this crystal may lose some of its water molecules while heating. Earlier report [11] on the infrared spectroscopic and thermal studies is restricted to pure calcium tartrate crystal only. As far as we are aware of, systematic FT-IR spectroscopic and thermal studies on impurity added calcium tartrate crystals are not found in the literature.…”

“…Calcium tartrate crystals are found to be exhibiting ferroelectric and non-linear optical properties [2,[7][8][9][10]. Growth and characterization of calcium tartrate tetrahydrate crystals, both pure and doped, have invited the attention of many authors in the recent years [11][12][13]. In the present study we have grown calcium tartrate tetrahydrate crystals using calcium formate mixed with formic acid as the supernatant solution.…”

Pure and impurity (strontium) added calcium tartrate tetrahydrate single crystals were grown by the gel method. The FT-IR spectra of these crystals were recorded in the wavenumber range 400 -4000cm. The thermograms of the grown crystals were recorded in the temperature range 50 -900 o C. FT-IR spectra reveals the presence of water molecules, O-H bond, C-O and carbonyl C=O bonds. The thermograms show that these crystals are thermally unstable and decompose into its oxide through many stages. DTA curve of the pure crystal shows three endothermic and one exothermic peaks.

“…The monoclinic b-axis is known to be parallel to spontaneous polarization direction. Therefore the b-cut (010) crystals are technologically important for many device applications [7][8][9]. Ferro electric TGS exhibits antiparallel 180 o domains, generally parallel to b-axis.…”
