Nicotinic acid widely known as Niacin are also known as vitamin B3 and vitamin PPis an organic compound with the formula C5H4NCO2H which is present in forty to eighty essential human nutrients. This colourless and water-soluble solid is a derivative of pyridine, with a carboxyl group (COOH) at the 3-position. Niacin was first described by Hugo Weidel in 1873 in his studies of nicotine [1]. Mild...

. Surface characterization techniques were used to evaluate adamantylethyltrichlorosilane (AdSi) as a potential coating to provide surface protection or as an initiator for diamond-like thin films. FT-IR and FT-Raman results indicate that, after formation and heating, the coating system has developed a cross-linked siloxane network. Quartz crystal microbalance and contact angle measurements wer...

Nitrogen-doped thiophene plasma polymer [N-ThioPP] thin films were deposited by radio frequency (13.56 MHz) plasma-enhanced chemical vapor deposition method. Thiophene was used as organic precursor (carbon source) with hydrogen gas as the precursor bubbler gas. Additionally, nitrogen gas [N2] was used as nitrogen dopant. Furthermore, additional argon was used as a carrier gas. The as-grown poly...

In this project, a three-component functionalization of carboxylated shortend multi-walled carbon nanotubes (MWNT-COOH) by Histidine derivative via amidation method have been investigated. The functionalized MWNTs were characterized by Fourier Transform Infrared spectroscopy (FT-IR), Raman spectroscopy, elemental analysis and scanning electron microscopy (SEM). 

Cobalt orotate trihydrate, [Co(C5N2O4H2)]·3H2O, has been synthesized and its crystal structure determined. The title compound crystallizes in the orthorhombic space group P212121 (no. 19) with a = 771.5(2), b = 788.9(7), c = 1470.4(2) pm, and Z = 4. Bridging orotate anions coordinate in a monoand bidentate manner to the Co atom resulting in infinite chains of alternating Co(II) cations and orot...

in this paper functionalized multiwall carbon nanotubes (fmwcnt) were modified using doxycycline, containing reactable nitrogen, which can attach chemically to functionalized mwcnt. the synthesized nano compounds were characterized by fourier transform infrared spectroscopy (ft-ir) and raman spectroscopy. these spectrums proved the existence of nitrogen atoms of amide functional groups. the mor...

In the present study, controllable microwave sintering was applied to prepare partially stabilised zirconia ceramics with enhanced phase composition and a more uniform structure. To reveal interface properties structural changes of PSZ during process, XRD, FT-IR, Raman, SEM characterisations were utilised. XRD analysis Raman demonstrated that increase temperature promoted martensite conversion....

Ž . We demonstrate that single-wall carbon nanotubes SWNT can be produced by an arc-discharge method using a catalyzed coal carbon source. Characterization by resonant Raman scattering and electron microscopy confirm that this material contains SWNT with properties similar to graphite-derived SWNT. ‘Web-like’ material from our growth process has an estimated yield of 45 wt.% of carbon as SWNT, ...

During this study, Fourier transform infrared spectroscopy (FT-IR), near infrared spectroscopy (NIR) and Raman spectroscopy were applied to 55 samples of counterfeit and imitations of Viagra and 39 samples of counterfeit and imitations of Cialis. The aim of the study was to investigate which of these techniques and associations of them were the best for discriminating genuine from counterfeit a...
