The crystal and molecular structures of the title compounds, ethyl 4-(4-hydroxyphenyl)-6-(6-methoxy-2-naphthyl)-2-oxocyclohex-3-ene-1-carboxylate (I) and ethyl 4-(3-bromophenyl)-6-(6-methoxy-2-naphthyl)-2-oxocyclohex-3-ene-1-carboxylate (II), are reported and confirmed by single crystal X-ray diffraction data. Compound (I), C26H24O5, crystallizes from a methanol solution in the monoclinic C2/c ...

Our numerical modelling of the Czochralski growth of single crystalline β-Ga2O3 crystals (monoclinic symmetry) starts at the 2D heat transport analysis within the crystal growth furnace, proceeds with the 3D heat transport and fluid flow analysis in the crystal-melt-crucible arrangement and targets the 3D thermal stress analysis within the β-Ga2O3 crystal. In order to perform the stress analysi...

Scandium nitride has recently gained interest as a prospective compound for thermoelectric applications due to its high Seebeck coefficient. However, ScN also has a relatively high thermal conductivity, which limits its thermoelectric efficiency and figure of merit (zT). These properties motivate a search for other semiconductor materials that share the electronic structure features of ScN, but...

A new charge transfer molecular complex salt of picric acid with m-toluidine was synthesized and the structure confirmed by single crystal X-ray diffraction (XRD) and NMR spectral analyses. Single crystals of m-toluidinium picrate have been grown by slow solvent evaporation solution growth technique using ethanol as the solvent at ambient temperature. The single crystal XRD analysis of MTP salt...

A chalcone derivative, 1-(5-bromothiophen-2-yl)-3-(2,3-dimethoxyphenyl)prop-2-en-1one (BTDMP), has been synthesized and grown as a high-quality single crystal by the slow evaporation solution growth technique. The compound was characterized by FT-IR and NMR studies. The crystal has been subjected to single-crystal x-ray diffraction studies and cell parameters of the crystal were determined. The...

The complete optical-gyration tensor for a monoclinic crystal of (2R, 3R)-(+)C4H6O6 has been determined by the tilter method at a wavelength of 680 nm. The tensor components in terms of rotatory power in relation to the principal axes of the indicatrix were found to be ρ◦ 11 = 79(7), ρ◦ 22 = 90(13), ρ◦ 33 = −70(4), ρ◦ 23 = −18(8)◦ mm−1 with ρ = −12.3(1.0)◦ mm−1 in the optic-axis directions. The...

Tetraketone and tetraaldehyde derivatives 2a-d were synthesized via the reaction of ethene-1,1,2,2,-tetra-yl-tetramethylene tetrabromide (1) with hydroxyketone and aldehyde derivatives. The molecular structures were identified by IR, (1)H-NMR, (13)C-NMR and MS analysis. The crystal structure of the title compound 2a, C(38)H(36)O(8), is reported. Its crystal data are: monoclinic, space group P 2...
