The mathematical fractional modeling of TiO_2 nanopowder synthesis by sol–gel method at low temperature

Titanium dioxide is a compound of oxygen and titanium with the formula TiO$_2$ present in nature and manufactured on an industrial scale.  It is used in several fields and applications such as cosmetics, paint, food, photocatalyst, electrodes in lithium batteries, dye solar cells (DSSC), biosensors, etc., given its importance and its various fields of application, there are several methods of synthesis of TiO$_2$ such as the sol–gel method widely used to obtain nanoparticles.  In our study, on the one hand we synthesized titanium dioxide nanopowders crystallized in the

Synthesis, Structure and Application of Mixed-Ligand Coordination Compounds of Copper(II) with Substituted Thioamides

New coordination compounds of copper(II) with substituted thioamides of the general formula [Cu(HL6-9)2X2]2 and CuL26-9 have been synthesized. The consecutive reaction of nucleophilic substitution/elimination of SN1/E1 in the octahedral complex [Cu(NH3)4Cl2]•H2O and catalytic hydrolysis of [Cu(HL6-9)2X2]2 complexes have been investigated.

Synthesis, Structure and Properties of Copper(II) Chelates with Benzimidazole-2-N-Arylcarbothioamides

Coordination compounds of general formula CuL have been obtained via complexation of copper(II) acetates and chlorides, as well as precipitated Cu(OH)2 with benzimidazole-2-N-arylcarbothioamides (HLI-IV). Monocrystal of [Cu(C16H14N3S)2]i-C3H7OH complex has been obtained by slow evaporation of CuL chelate saturated solution in isopropyl alcohol. The obtained compounds were investigated by means of elemental, XRD analysis and IR-spectroscopy.

Synthesis and Crystal Structure of Cadmium(II) Dichloroaquasalicylidenesemicarbazone

Cadmium(II) complex with salicyl aldehyde semicarbozone (Н2L) has been synthesized. Based on elemental analysis and IR spectroscopy its composition – [Cd∙Н2L∙H2O∙Cl2] – has been established. The complex crystal structure has been examined using XRD analysis. The coordination polyhedron of cadmium atom is a distorted octahedron, where two cis-positions are occupied by oxygen atoms of water molecule and carbamide fragment of H2L molecule, other positions are occupied by chlorine atoms.
