Abstract: The purpose of this study is to produce scarf joint through explosive welding process (EXW). The scarf weld is a process in which the final bond interface is oblique. With applying the explosive welding technique, this joint can create a metallic bond between similar or dissimilar metals. In this study, chamfered end of aluminum and copper plates were joined explosively and named scar...

In the title compound, C(13)H(10)N(2)O(2), a Schiff base derivative, the dihedral angle between the two aromatic rings is 31.58 (3)°. The C=N double bond is essentially coplanar with the nitro-phenyl ring. The torsion angle of the imine double bond is 175.97 (13)°, indicating that the C=N double bond is in a trans configuration. The crystal structure is stabilized by C-H⋯O contacts and π-π inte...

The distribution of Ge-O-Ge and Si-O-Si bond angles α in amorphous germania and silica is re-determined on the basis of diffraction experiments. The bond angle α joining adjacent tetrahedra is the central parameter of any continuous random network description (CRN) of these glasses. New high energy photon diffraction experiments on amorphous germania (at photon energies of 97 and 149 keV) are p...

The title compound, C(4)H(3)BrO(4), was obtained from a solution of meso-2,3-dibromo-succinic acid and vanadium(IV) oxide. The crystals are isostructural with chloro-maleic acid and the mol-ecule has two geometrically different carboxyl groups, one of which has delocalized C-O bonds and is essentially coplanar with the olefinic bond plane [give dihedral angle 15.08 (16)°], whereas the other has...

The mechanism for hydrogen bond (H-bond) switching in solution has remained subject to debate despite extensive experimental and theoretical studies. We have applied polarization-selective multidimensional vibrational spectroscopy to investigate the H-bond exchange mechanism in aqueous NaClO4 solution. The results show that a water molecule shifts its donated H-bonds between water and perchlora...

In the title compound, C(14)H(13)NO(3)S, the conformation of the N-H bond in the C-SO(2)-NH-C(O) segment is anti to the C=O bond. The tolyl and benzoyl groups are twisted about the S-N bond, with a C-S-N-C torsion angle of 68.8 (4)°. The dihedral angle between the sulfonyl and the benzoyl benzene rings is 73.9 (1)°. In the crystal, the mol-ecules are linked into C(4) chains along the c axis by ...

The title compound, C12H9BrN2OS2, was obtained by reacting 6-bromo-benzo[d]thia-zole-2-carbo-nitrile in iso-propanol with ethyl 2-mercapto-2-methyl-propano-ate at reflux temperature for several hours. The resulting di-methyl-oxyluciferin derivative shows partial double-bond character of the carbon-carbon bond between the two heterocyclic moieties [C-C = 1.461 (3) Å]. This double bond restricts ...

The effect of target polarization fields on the bond-angle distribution following the foil-induced Coulomb explosion of CH2 + has been measured. Incorporating a detailed model description of the polarization effects and other target effects into a Monte Carlo simulation of the experiment, a good description of the various observables is obtained. In particular, the bond-angle distribution is fo...

In the crystal structure of the title compound, C(13)H(9)ClN(2)O(5)S, the N-H bond is trans to the C=O bond (H-N-C-O torsion angle = 158.4°). The dihedral angle between the two aromatic rings is 87.8 (1)°. In the crystal, mol-ecules are linked into chains along the b axis via N-H⋯O hydrogen bonds.
