“…Peak (435) indicates stock line that is not defined as polymer or nTiO 2 ; it may indicate percolation threshold and tunneling effect [18] that may take place within SR8100/nTiO 2 PMNC. Finally (585) peak refers to nTiO 2 and/or deformation of C-C and C-O [19,22,23]. The Raman shift results of this work are in agreement with FTIR results shown in Fig.…”

raman shift, Ftir spectra and sem were used to detect the percolation threshold of nano titania filler ceramic ntio 2 dispersed in a silicon rubber matrix sr8100 by hot vibrate dispersion. it has been found that an additional frequencies, and stock lines appears in raman shift when ntio 2 reach (5)wt% which mean a change in polarity of the sr8100/ntio 2 Pmnc polarity. keywords: Pmnc, nano ceramic oxide fillers, ntio 2 , raman shift

“…It was found that the oxidation current peak of AA at 600 mV effected on the redox current peaks of the contrast medium, causing the disappearance of anodic (oxidation) current peak of the contrast medium and the enhancement of cathodic (reduction) current peak at -900 mV. Hence, AA acted as an electrocatalyst reagent for safely using gadolinium compounds in blood medium [26][27][28][29].…”

Gadolinium compounds have been used as a common contrast media in MRI technique; however, they have oxidation-reduction current peaks in blood medium. To propose a solution for this problem, the alternative of contrast media in magnetic resonance imaging (MRI) was studied by electrochemical method using cyclic voltammetric technique. Magnesium compound was chosen such as MgCl 2 which has a good electrochemical properties especially in blood medium. It was found that Mg (II) ions in blood medium acted as an antioxidative reagent. The results of this study focused on the effect of magnesium chloride ions in normal saline, KCl solution and blood medium in presence with ascorbic acid (AA) and folic acid (FA) and understanding the redox current peaks of Mg (II) ions in these conditions. We obtained good results by using MgCl 2 solution as an alternative contrast medium in MRI technique instead of using of gadolinium compounds.

“…In the spectra of CH-BNT and AZ-BNT, the absorption bands at 3626 and 3640 cm‾ 1 indicate the presence of free O-H stretching and at 1091 and 1109 cm‾ 1 correspound to C-N stretching [19,20]. In addition to the bands of the original Na-BNT, the band at 1490 and 1438 cm‾ 1 suggests the existence of the ammonium ion.…”

Organclays (OBNTs) were prepared using two new organic surfactants including 3-(4-aminophenyl)-1-(4-chlorophenyl)prop-2-en-1-on (CH) synthesized from a Claisen-Schmidt condensation reaction between p-aminoacetophenone and p-chlorobenzaldehyde; and 4-((4-nitrophenyl)diazenyl)-N-(pyrimidin-2-yl) (AZ) prepared from reaction of sulfadiazine and p-nitoaniline. Organclays OBNTs were characterized by Fourier transform infrared spectroscopy (FTIR) to evaluate the incorporation of surfactants in bentonite. The X-ray diffraction (XRD) technique was utilized to indicate the basal spacing of the treated clay as a measure of susceptibility of new organoclays. The FTIR and XRD results showed that the OBNTs were successfully incorporated in the layers of bentonite clay. Thermogravimetric analysis (TGA) was also used to determine thermal stability. An enhancement in stability was observed in OBNTs compare to pure bentonite. OBNTs prepared in this study can be used to produce disposable packaging a promising polymer nanocomposite.
