In this study, the performance of the Sequential Gaussian Simulation (SGS) approach was studied with the aim of accurately determining local health risk distributions associated with trace elements (V, Cr, Mn, Co, Ni, Cu, Zn, As, and Pb). This study plays a crucial role in determining the distribution of health risk levels, especially from heavy me...

In this study, synthesis of CsPbBr3 perovskite single-crystals in a hydrobromic solution was investigated. Single-crystal growth experiments were conducted at the solution-nucleation border at a constant temperature or controlled cooling conditions. Working at the solution-nucleation border poses some practical difficulties such as fast precipitati...

In this study, rhodium, palladium, platinum, gold and cerium were determined by ICP-MS after trace-matrix separation in roadside dusts and soil samples along different motorways in Ankara and Bursa, and in soil samples taken from industrial locations in Nilüfer, Bursa. The clear presence of Pd and Rh was determined at different traffic locations. P...

Aqueous slurries of hydrothermally prepared barium titanate (BaTiO3) powders were tape casted without the use of large anisotropic template materials. The tapes were sintered at 1400°C or 1500°C, and at different furnace parameters. The texture of the sintered tapes was evaluated by the semi-quantitative XRD Lotgering method and the microstructure...

In this work, the X-ray mass attenuation coefficients of hydrothermally synthesized barium titanate (BaTiO3) samples were calculated with the purpose of determining the crystallization sequence of BaTiO3. Hydrothermally synthesized samples prepared at 100 °C and 200 °C, and reacted for varying reaction times between 15 min up to 120 h were studied....

Barium titanate (BaTiO3) was produced from an barium-titanate-peroxo-hydroxide precursor material in NaCl-KCl and Na2SO4-K2SO4 salt mixtures or fluxes at temperatures up to 1080 °C via the molten-salt synthesis (MSS) method. Beside the different salt mixtures several other parameters were studied to determine the effect on the particle morphology....

In this work, the absorption coefficient of hydrothermally synthesized barium titanate (BaTiO3) was calculated. BaTiO3 was prepared via the peroxo-hydroxide method and hydrothermally synthesized at 80°C, 100°C, 150°C, 200°C and reacted for varying reaction times between 15 min up to 120 h. Absorption coefficient measurements were done with a coaxia...

(Elsevier Share Link: http://authors.elsevier.com/a/1SyqF~2-Enn2X) Tetragonal cube-shaped barium titanate (BaTiO3) was produced by the hydrothermal treatment of a peroxo-hydroxide precursor, a single-source amorphous barium titanate precursor, in a highly concentrated sodium hydroxide solution. Phase pure barium titanate with cube-shaped morphology...

(Elsevier Share Link: http://authors.elsevier.com/a/1SPJW~2-EiuXc) Barium titanate powder was processed by slip casting in a rotating strong magnetic field of 9.4. T. The orientation factor of the sintered compact was analyzed by the X-ray diffraction technique and the microstructure (grain-size) was analyzed by scanning electron microscope. The hy...

In this paper, the amorphous barium titanate precursor was prepared by the peroxo-hydroxide method and post-treated by various drying procedures, such as: room temperature drying, room temperature vacuum drying and vacuum drying at 50°C. The objective in the latter two treatments was to increase the Ti–O–Ba bonds of the precursor. The post-treated...

Fabrication of barium titanate (BaTiO 3) powder for the purpose of colloidal processing in a 9.4 T (Tesla) magnet is discussed here. Hydrothermally prepared BaTiO 3 powders were tested inside a 9.4 T magnetic field with a static field. Rheological studies showed that suspensions prepared with a polymethacrylate acid (PMAA) dispersant, pH adjusted t...
