The title compound, [BaCl(2)(C(2)H(6)SO)], forms a Ba(6)Cl(9) cluster in which the BaCl(2) units are connected via dimethyl-sulfoxide (DMSO) and chloride bridges. The central Cl atom of the Ba(6)Cl(9) cluster is located on a threefold inversion axis and is coordinated octa-hedrally to six barium cations. In the crystal, the clusters are arranged in rows, which are inter-connected by the DMSO mo...
this study reports the simple process to synthesis of cuo/cui nanocomposite in a non-aqueous solution. in the conducted experiments cui and dimethyl sulfoxide (dmso) were used as the precursors. moreover, dmso had role of solvent and ligand simultaneously. in experiments the effects of oleic acid as the particles size modifier, temperature and concentration were investigated. crystalline struct...
The dissolution of cellulosic flax fibres in the ionic liquid 1-ethyl-3-methylimidazolium acetate ([C2mim][OAc]) with cosolvent dimethyl sulfoxide (DMSO) has been studied. were submerged liquid/DMSO mixtures at different temperatures for a range times, then coagulated water. After drying, cross sections analysed using an optical microscope, which was used to track fraction fibre. temperature de...
For the first time possibility of using thermomechanical analysis to construct fragments state diagrams cryoprotective solutions in zone glass transition temperatures has been considered. A method for studying cluster crystallization based on curves developed. The parameters frozen aqueous dimethyl sulfoxide (DMSO), polyethylene oxide 1500 (PEO-1500), glycerol were analyzed and relationship bet...
For the first time a sulfur solution in dimethyl sulfoxide (DMSO) with concentration of 1.592 g/L [1] was used to prepare nanoparticles (nanosulfur). Synthesis and stabilization colloidal particles carried out at 298K (25°C) by diluting DMSO water 10 1000 times. The stable sizes nanosulfur measured dynamic light scattering were ~ 100 nm. results confirmed both qualitatively quantitatively ...
The studies demonstrated that the use of dimethyl sulfoxide (DMSO) as a vehicle for dimethylbenzanthracene in the produc tion of experimental tumors in the hamster cheek pouch, sig nificantly reduced the latent period for tumor production when compared to the usual mineral oil vehicle. No systemic or local changes could be attributed to the DMSO itself, and the mor phology of induced tumors was...
Solvent–solute interactions in precursor solutions of lead halide perovskites (LHPs) critically impact the quality solution-processed materials, as they to formation a variety poly-iodoplumbates that act building blocks for LHPs. The [PbI2+n]n? complexes is often expected diluted solutions, while coordination occurring at high concentrations not yet well understood. In combined ab initio and ex...
A mixture of solid KOH in dimethyl sulfoxide has a strong basicity, but only a low nucleophilicity and is used for Q methylation of ketones. With this simple and inexpensive reagent complete methylation with yields up to 90% can be achieved. Solid KOH in dimethyl sulfoxide (DMSO) is a very strong base with a pKa-value of 27 or even higher. l-3 On the other hand, the nucleophilicity of this reag...
(Effects of trans-resveratrol and dimethyl sulfoxide on intermediate metabolism and lipoperoxidation in Drosophila melanogaster). Many plants contain the phytoalexin trans-resveratrol. Red grapes and peanuts are rich in this antioxidant which is thought to be responsible for the reported protective effect of wine against diseases and also the ability to retard aging. We investigated the effects...
The title salt, [Mn(C2H6OS)6]I4, is made up from discrete [Mn(DMSO)6]2+ (DMSO is dimethyl sulfoxide) units connected through non-classical hydrogen bonds to linear I42- tetra-iodide anions. The MnII ion in the cation, situated on a position with site symmetry -3., is octa-hedrally coordinated by O atoms of the DMSO mol-ecule with an Mn-O distance of 2.1808 (12) Å. The I42- anion contains a neut...
