We prepared and then blended polyurethanes (PUs) with poly(methyl methacrylate)s (PMMAs) and TiO2 by varying the percentage compositions to form pellets. The chemistry of all of the blended samples was confirmed by Fourier transform infrared spectroscopy. The incorporation of TiO2 into the PU-PMMA matrix was confirmed with scanning electron microscopy analysis. Differential scanning calorimetry analysis and compression testing was performed, and the results are discussed. The cytotoxicity level of the prepared blends displayed dependence on the composition ratio of the PU-PMMA blends. The results reveal that the optimum PU contents in the PU-PMMA-TiO 2 blend were responsible for its better biocompatibility. © 2013 Wiley Periodicals, Inc. Source

In the title compound, C22H23NO4S 2, the dihedral angles between the dimethylphenyl ring and the two methylphenyl rings are 41.19 (15) and 20.50 (17)°; the dihedral angle between the methylphenyl rings is 48.11 (14)°. The C - N - S - C torsion angles are - 87.6 (2) and 77.43 (18)°. The only possible directional interactions in the crystal are very weak C - H·π interactions and very weak π-π stacking between parallel methylphenyl rings [centroid-to-centroid separation = 4.010 (2) A and slippage = 1.987 Å].

Surfactant controlled synthesis of magnesium oxide-tin oxide (MgO-SnO2) nanocatalysts was carried out via the hydrothermal method. Concentration of sodium dodecyl sulfate (SDS) was varied while all other reaction conditions were kept constant same for this purpose. Furthermore, MgO-SnO2 nanocatalysts were also prepared by changing the precursor's concentration. These precursors are magnesium nitrate Mg(NO3)2· 6H2O and tin chloride (SnCl4·5H2O). The influence of these reaction parameters on the sizes and morphology of the nanocatalysts were studied by using Fourier transform infrared (FTIR) spectroscopy, Scanning electron microscopy-Energy dispersive X-ray (SEM-EDX), Powder X-ray diffraction (XRD), Transmission electron microscopy and Thermo gravimetric analysis (TGA). The catalytic efficiency of MgO-SnO2 was checked against 2,4-dinitrophenylhydrazine (DNPH), which is an explosive compound. The nanocatalysts were found as a good catalyst to degrade the DNPH. Catalytic activity of nanocatalysts was observed up to 19.13% for the degradation DNPH by using UV-spectrophotometer. © 2015 Pleiades Publishing, Ltd. Source

In the title compound, C13H11Cl2NO2S, the dihedral angle between the aromatic rings is 76.62 (10)°and the C-S-N-C linkage between the rings adopts a gauche conformation [torsion angle =-51.4 (2)°]. A weak intra-molecular C-H⋯O inter-action closes an S(6) ring. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R 2 2(8) loops. Source
