In this paper, the thermoluminescence (TL) dosimetric characteristics of Al-doped LiB3O5 compounds are presented. The powder samples were prepared by the solid-state reaction method and the formation of the compounds were confirmed by an X-ray diffraction study. The TL studies of undoped and Al-doped LiB3O5 samples showed similar glow curve structures. They have three TL glow peaks at about 60, 130 and 200 degrees C after heating at a constant heating rate of 1 degrees C/s. Their comparative TL studies indicated that 5 wt% Al-doped LiB3O5 compound was approximately 240 times more sensitive than undoped compound. The TL emission spectra of Al-doped LiB3O5 showed a maximum band at around 520 nm. The main dosimetric characteristics, which are namely the TL dose response, TL sensitivity, fading, minimum detectable dose, reproducibility, precision of dose measurement and annealing procedure, indicated that Al-doped LiB3O5 sample, can be used in dosimetric applications. The trap parameters namely order of kinetics (b), activation energy (E) and frequency factor (s) associated with the glow peaks in beta irradiated undoped and Al-doped LiB3O5 samples were obtained by glow curve deconvolution (GCD) program.

Investigation of neutron sensitivity of un-doped and Dy-doped CaB4O7 for thermoluminescence applications Iflazoglu, Sera; Yılmaz, Ayşen; KAFADAR, VURAL EMİR; YAZICI, AHMET NECMEDDİN (2018-09-01) In this study, thermoluminescence characteristics of un-doped and Dy-doped calcium tetraborate (CaB4O7) compounds are reported. The polycrystalline powder samples of un-doped and Dy-doped CaB4O7 were prepared by a solid-state reaction at high-temperature method. The identification and characteristics of the obtained compounds were determined by X-ray diffraction, Fourier transform infrared analysis, differential thermal analysis, thermogravimetric analysis, and scanning electron microscopy. The glow curves ...
Analysis of the Junction Properties of C/GaSe<sub>0.5</sub>S<sub>0.5</sub>/C Back-to-Back Schottky-Type Photodetectors Khanfar, Hazem K.; Qasrawi, Atef F.; Hasanlı, Nızamı (Institute of Electrical and Electronics Engineers (IEEE), 2015-4) In this paper, a C/GaSe0.5S0.5/C metal-semiconductor-metal photodetector is suggested and described. The device is explored by means of current-voltage and capacitance-voltage (C-V) characteristics under different photoexcitation intensities. It was observed that the design of the back-to-back Schottky device has reduced the dark current of the normal Ag/GaSe0.5S0.5/C Schottky diode by 13 times and increased the photosensitivity from 3.8 to similar to 2.1x10(3). The device exhibited a barrier height of 0.84...
The effect of conceptual change approach on students' understanding of solubility equilibrium concepts Önder, İsmail; Geban, Ömer; Department of Secondary Science and Mathematics Education (2006) The main purpose of this study was to compare the effectiveness of instructions one based on conceptual change approach and the other based on traditional chemistry instruction on tenth grade high school students’ understanding of solubility equilibrium concept. In addition, students’ attitudes toward chemistry as a school subject and toward conceptual change texts were investigated. Moreover, students’ science process skills were also investigated. 125 tenth grade students from four classes of a chemistry ...
A comparative study of force-deformation relationship of FRP-confined concrete columns Erdil, Barış; Akyüz, Uğurhan; Yaman, İsmail Özgür; Irfanoglu, A. (null; 2011-10-26) In this study, the FRP-confined concrete models for prismatic members given in the ACI440.2R-08 and Turkish Earthquake Code (TEC2007) are compared with the experimental data taken from the literature. It is found that TEC2007 assumes only hardening behavior for concrete strengthened with FRP. Although ACI440.2R-08 assumes a hardening and softening behavior depending on the confinement-effectiveness, the limit separating the hardening and softening must be improved to predict the behavior well. The assumptio...
The effect of soluble boron on the burnup at different enrichments and assemblies Gündüz, Güngör; Ajwah, Yousef (Elsevier BV, 1989-5) The effect of boron on the optimum burnup was investigated at different assemblies for enriched fuels. As the enrichment increases, an alteration in the assembly type is needed for the optimum specific power. This alteration can be made at lower enrichments due to the presence of boron. The optimum specific power is shifted toward the high enrichment fuels when the assembly number is increased. If a fuel of high enrichment is first burnt in a highly hardened neutron spectrum and later in a softer spectrum t...
