چکیده
Abstract Nanocrystalline boehmite material was synthesized using the hydrothermal method. Different annealing temperatures have been used to transform into different alumina phases study effect of phase transitions on thermoluminescence properties alumina. XRD analysis carried out investigate crystal structure phases. The glow curves for showed structures; however, sensitivity almost constant all over applied dose ranging from 0.55 330 Gy.

Detection of tetragonal zirconia in alumina–zirconia powders by thermoluminescence
The thermoluminescence (TL) after excitation by UV or X-rays radiation of alumina-zirconia powders is investigated. The composites present five of the characteristic peaks of zirconia at −170, −145, −90, 0 and 95 °C. After a thermal treatment of mixed oxides, a new peak is observed at −35 °C in TL. This peak reveals the presence of stabilized tetragonal zirconia in the material. Moreover by com...
متن کاملNUMERICAL SIMULATIONS OF THE PHASE TRANSITIONS IN CLUSTERS
We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. It is shown that all the main features of the bulk phase transitions are e...
متن کاملThermoluminescence characteristics of Ge-doped optical fibers with different dimensions for radiation dosimetry.
Important thermoluminescence (TL) properties of five (5) different core sizes Ge-doped optical fibers have been studied to develop new TL material with better response. These are drawn from same preform applying different speed and tension during drawing phase to produce Ge-doped optical fibers with five (5) different core sizes. The results of the investigations are also compared with most com...
متن کاملWear debris from two different alumina-on-alumina total hip arthroplasties.
We compared wear particles from two different designs of total hip arthroplasty with polycrystalline alumina-ceramic bearings of different production periods (group 1, before ISO 6474: group 2, according to ISO 6474). The neocapsules and interfacial connective tissue membranes were retrieved after mean implantation times of 131 months and 38 months, respectively. Specimen blocks were freed from...
متن کاملSynthesis and thermoluminescence properties investigation of nano-structured alumina for high dose measurement
In this study, nanostructured alumina was synthesized by solution combustion method and its thermoluminescence properties was investigated. X-raydiffraction (XRD) and scanning electron microscopy (SEM) were conducted to investigate the crystal structure, morphology and the particle size of the powders. It was observed that nano structured α-Al2O3 particles with nano flake morphology and thickne...
