The process of germanium–tannin complex is the oldest form technology for extracting germanium from Ge-containing solutions. This reaction mechanism relatively controversial as it imposes restrictions on ideas and methods reducing amount tannin. In this paper, using SEM, TEM, FT-IR, XPS, NMR, TOF-SIMS UV diffuse reflectance spectroscopy a deep analysis complex, solutions with tannins investigat...

LTA Zeolite nanoparticles was successfully synthesized from clear solution under controlled conditions using hydrothermal method using tetramethyl ammonium hydroxide as a structural directing agent. The as-synthesized LTA zeolite particles were characterized by powder X-ray Diffraction (XRD) analysis, Scanning Electron Microscopy (SEM), Fourier Transform InfraRed (FT-IR) spectroscopy, </e...

3-chloro-2-{(2Z)-2-[1-(4-methoxyphenyl)ethylidene]hydrazinyl}pyridine (HL) was prepared and its structure elucidated by LC/MS-MS, 1H 13C-NMR, UV-Vis, elemental analysis, FT-Raman FT-IR. All theoretical calculations optimized geometry were obtained from the 6-31G(d,p) basis set calculations. Calculated scaled data of molecule compared with observed FT-IR spectroscopic data. The chemical shifts H...

Borosilicate BK7 glasses doped with different amounts of CeO2 (0.5,1,1.5%) were prepared by the convenient melting process in this work. DTA analysis proved that 0.5-1% CeO2 has a network modifier role and then up to 1.5% it shows network former role.For structural studies, FT-IR and Raman spectroscopy were carried out. Fermi energy level, direct/ indirect optical band gap and Urbach energy wer...

A series of new 2-(phenylthio) benzoylaryl hydrazones were synthesized by acid-catalyzed condensation of hydrazide 3 with corresponding aldehydes. The chemical structures of the compounds were elucidated by FT-IR, 1H-NMR and Mass spectra. All newly synthesized compounds were evaluated for their antimycobacterial activities against Mycobacterium tuberculosis H37Rv using the microplate alamar blu...
