Abstract:

This study involves the synthesis of asterism compounds (D1-D6) through the reaction of 1 mole of benzene 1,3,5-triol with 3 moles of prepared pentacyclic ring ester derivatives, dissolved in absolute ethanol. The validity of the compound structures was confirmed using physical and spectroscopic methods such as infrared spectroscopy, and proton nuclear magnetic resonance spectroscopy. Additionally, melting points and purity were determined, and reaction progress was monitored by Thin-Layer Chromatography (TLC). The liquid crystal phases of certain prepared compounds were examined using a polar

Abstract:

This paper considers the synthesis and investigation of cyclic silicon-organic polymers with mono- and polycyclic fragments in the side chain. For obtaining monocyclic polymers, the hydrosilylation reaction of 1-hydro-3-vinylhexamethylcyclotetrasiloxane was used. The reaction was conducted in a CCl4 solution at 75°C in the presence of Speier’s catalyst (H2PtCl6  6H2O) to produce a viscous-flow at room temperature polymer. The polymers were studied by NMR spectroscopy. Poly(carbosiloxane) with cyclic fragments in the methyl-siloxane backbone was synthesized by the hydride polyaddition of divin

Abstract:

Amorphous calcium phosphate tube-like structures were formed on magnesium substrates using a straightforward electrochemical process. The effect of voltage, time and the resulting hydrogen gas evolution were found to be responsible for sculpturing the tube-like structures covering the entire substrate surface. Scanning electron microscopy and Energy Dispersive Spectroscopy was used to quantify the size, shape, structure and composition of the tube-like structures. Microscopy analysis was used to develop a model to describe the mechanism behind the formation of the tube-like structures. Also in

Abstract:

Organothiophosphoryl polyoxotungstates R2XW11O39n− , R2P2W17O616− , R2PW9O345− , (X = P, Si, Ge, B or Ga; R = PhP(S), C6H11P(S)) have been prepared from lacunary polyoxoanions and PhP(S)Cl2 or C6H11P(S)Cl2. The products were characterized by elemental analysis, IR, P31 and W183 NMR spectroscopy. According to spectroscopic observations, the hybrid anions consist of a lacunary anion framework on which are grafted two equivalent C6H5P(S) or C6H11P(S) groups through P-O-W bridges. Some of the title compounds showed the antigerm activity.

In this work, we report preparation and characterization of dodecylbenzene sulfonic acid (DBSA) doped tetraaniline via micelles assisted method using ammonium per sulphate (APS) as an oxidant. Here, DBSA act as dopant as well as template for tetraaniline nanostructures. The synthesized DBSA doped tetraaniline have been well characterized by X-ray diffraction patterns, Fourier transform infrared spectroscopy, UV-Visible spectroscopy, Scanning electron microscopy and thermogravimetry. The morphologies of tetraaniline were found to be dependent on molar ratios of N-phenyl-1, 4-phenylenediamine to

Abstract:

This work is concerned with the preparation of a number of organic ammonium formate salts (or ionic liquids; ILs) throughout a reaction between the formic acid and some aliphatic and aromatic amines including the ammonia. Five organic ammonium formate salts were formed, some of them were in the form of solid salts and others were as the ionic liquids (ILs) at room temperature. The yields of the prepared organic salts ranged from (21%) to (79%). However, some attempts towards the preparation of other fifteen organic salts were not successful. The resulting five organic ammonium formate salts/io

<strong>Abstract:</strong> This article presents synthesis of novel Schiff base ligand from N-salicylidene-p-chloroaniline and its Co (II) complex in ratio 1:2 metal-ligands. The complex formed was subjected to elemental analysis and spectroscopic studies (ultraviolet spectroscopy and infra-red spectroscopy) alongside melting point evaluation. From the infrared spectroscopy of the complex, an octahedral arrangement of the ligand around cobalt atom is proposed. The complex formed showed the stability at an ambient condition and it was soluble in most organic solvents. <strong>Keywords:</strong>

Abstract:

Under simulated light irradiation, the aerobic oxidation of benzylamine to N,N-benzylidenebenzylamine was carried out as a model reaction to investigate the photocatalytic activity of a hydrothermally prepared composite based on BiOF and BiFeO3 materials. The prepared photocatalysts were characterized using several spectroscopic techniques, such as powder X-ray diffraction (PXRD), diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and Fourier transform infrared spectroscopy (FTIR). Band gap analysis showed that the composite
