Öğe Crystal structure of 4-(1-mesityl-1-methylcyclobutane-3-yl)-2-(N-ethyl)aminothiazole(Japan Soc Analytical Chemistry, 2002) Sarı, U.; Güven, K; Yılmaz, I.; Cukurovali, A.; Aksoy, I.…Öğe Crystal structure of 4-(1-methyl-1-mesitylcyclobutane-3-yl)-2-aminothiazole(Wiley-V C H Verlag Gmbh, 2006) Aksoy, I.; Yılmaz, I.; Sarı, U.; Güven, K.; Çukurovalı, A.The crystal structure of 4-(1-methyl-1-mesityleyclobutane-3-yl)-2-aminothiazole (C17H22N2S1) has been determined by X-ray crystallographic techniques. The compound crystallizes in the triclinic space group P-1 with Z = 6. The crystal structure was solved by direct methods and refined by full-matrix least squares to a final R-value of 0.052 for 2298 observed reflections [I > 2 sigma (I)]. There are three crystallographically independent molecules, I, II and III. These molecules are held together by intermolecular N-H...N hydrogen bonds.Öğe Effects of thermal treatments on mechanical properties of Cu-24.2%Mn alloy(Natl Inst Optoelectronics, 2012) Aldirmaz, E.; Celik, H.; Tekelioglu, A.; Aksoy, I.In this work, some physical and mechanical properties of Cu-24.2%Mn (wt %) alloy have been investigated by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and compression deformation test. Austenite phase has been obtained in the samples by applying slowly cooling and rapidly cooling processes according to the SEM analysis. It has been observed that the grain size obtained by the rapidly cooling is smaller than the grain size obtained by the slowly cooling. Therefore, it has been concluded that the cooling process differences change the grain size of the alloy. Compression stress has been applied to the alloy in order to research the deformation effect on the austenite phase. Slip lines and martensite structure were observed on the surface of the alloys after the deformation. In the present work, shows that, in the slowly cooling and deformation provide not in effects of diriving forces on martensitic transformation, but the rapidly cooling and deformed sample was observed gamma(1)' (2H) martensite.Öğe Investigation of deformation and microstructure of bainite in Cu-9.97%Al-4.62%mn alloy(Technical Faculty, Bor-Serbia, 2014) Aldirmaz, E.; Aksoy, I.In this study, some physical and mechanical properties in Cu-9.97%Al-4.62%Mn (wt%) alloy were investigated by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and compression deformation test. Bainite phase were obtained in the samples according to SEM and XRD analyses. Compression stress was applied on the alloy in order to investigate the deformation effect on the bainite phase transformation. On the surface of the Cu-9.97%Al-4.62%Mn alloy after the deformation, both bainite and martensite variants formed.Öğe SEM and X-Ray Diffraction Studies on Microstructures in Cu-26.04%Zn-4.01%Al Alloy(Polish Acad Sciences Inst Physics, 2013) Aldirmaz, E.; Celik, H.; Aksoy, I.Due to fact that Cu-based alloys are very sensitive to the thermal treatments, in scanning electron microscopy and X-ray diffraction observations, according to the different quenching techniques Cu-26.04%Zn-4.01%Al alloys can display different product phases such as martensite and precipitation. Rapidly cooling sample was formed as M18R structure from the ordered DO3 phase and in the monoclinic case, beta = 89.1 degrees determined for sample. It was seen that a a-precipitation (fcc) phase in the matrix is slowly cooling.Öğe X-ray diffraction study and electrical properties of the metal complex Fe(II) including sodium oxalate ligand (Na2C2O4)(Elsevier Science Bv, 2002) Aydoğdu, Y.; Yakuphanoğlu, F.; Dağdelen, F.; Şekerci, M.; Aksoy, I.The crystal structure, microstructure and electrical properties of the Fe(II) complex including sodium oxalate ligand (Na2C2O4) have been investigated. X-ray diffraction data shows that the sample is triclinic with the cell parameters a = 4.8283 Angstrom, b = 3.9195 Angstrom, c = 12.7633 Angstrom, beta = 97.818degrees and cell volume V = 239.30 Angstrom(3). The do conductivities have been measured as a function of temperature. It is seem that this sample has inorganic semiconductor property. (C) 2002 Elsevier Science B.V.

The crystal structure of samples at room temperature was examined using X-ray diffraction (XRD). X-ray diffraction showed that the three samples have different crystal structures. The microstructures of the samples have also been investigated by scanning electron microscopy (SEM). These samples have been found to be inorganic semiconductors having moderate conductivities and activation energies. Room temperature conductivities of O-Co, O-Ni, and O-Cu. samples were 6.43 x 10(-9), 3.85 x 10(-7), and 2.10 x 10(-6) S/cm, respectively. The mobility and concentration of the carriers were calculated by means of current-voltage curve samples in the space charge limited region (SCLC). (C) 2002 Elsevier Science B.V.
