AB  - For the first time, particle shape analysis of silica coated iron oxide (maghemite/magnetite) nanoparticle clusters (core-shell nanostructures) is discussed using computational methods. We analyzed three samples of core-shell nanostructures synthesized with different thickness of the silica shell. A new computational method is presented and successfully applied to the segmentation of the core-shell nanoparticles, as one of the main problems in image analysis of the TEM micrographs. We have introduced the circularity coefficient, marked with k(circ) and defined as the ratio of circularity measure C-2(S) of nanoparticles core and circularity measure core-shell nanoparticles in order to answer the question how the shell affects the overall shape of the final core-shell structure, with respect to circularity. More precisely, the circularity coefficient determines whether the circularity of the core-shell nanoparticle is higher, lower or equal to the circularity of the core. We have also determined the shells share in the overall area of the core-shell nanoparticle. The core-shell nanoparticle clusters here investigated exhibit superparamagnetic properties at room temperature, thus emphasizing their potential for use in practical applications such as in biomedical and particle separation. We show that the saturation magnetization strength can be easily adjusted by controlling the thickness of the silica shell. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

AB  - Radiation sensing MOSFETs have found numerous applications as detectors or device components in radiation fields used in nuclear industry, medical applications and space research. Monte Carlo simulations of MOSFET energy response to X-ray and gamma radiation for different packaging were performed. The photon transport Monte Carlo software FOTELP-2K10 has been adapted to obtain the energy deposited in MOSFET structure with microscopic dimensions. In this work the ratio between values of total energy deposited in the sensitive volume (thick SiO2 layer) for cases of MOSFET structure with and without package lid is presented. For this purpose is defined the shielding energy dependence factor (SDEF), and gave its value for kovar and Ti-24Al-11Nb and Ti-13Nb-13Zr alloys as lid materials.

AB  - The interaction between Sr2+ ions and variously treated animal bones was studied from the aspect of Sr-90 isotope immobilization from the contaminated effluents. As a source of biogenic, poorly-crystalline apatite, bone based materials, in general, were found to exhibit good retention properties towards Sr2+ cation. Furthermore, sorption capacities of H2O2 treated bone sample and sample annealed at 400 degrees C were found to be higher in respect to a commercial bone char and synthetic hydroxyapatite. Mentioned treatments induced partial organic phase removal from the pores of the skeletal material that caused the increase of the specific surface area. Higher temperatures provoked an increase of the apatite phase crystallinity, agglomeration of nano-crystals and a decrease of both the specific surface area and Sr2+ sorption. The immobilization was pH independent in the range 4-10, as a result of sorbents buffering properties. Kinetic data were well represented by the pseudo-second-order reaction model. Sorption isotherms were in better correlation with Freundlich than Langmuir theoretical model, whereas samples heated at 800 degrees C and 1000 degrees C showed S-type isotherms which were in a good agreement with sigmoidal Langmuir equation. The ion-exchange with Ca2+ cations and the specific cation sorption were two recognized mechanisms in the Sr2+ removal process, with relative contributions strongly dependent on the sorbents physicochemical properties. Sr2+ -loaded products were the most stable in the neutral and alkaline environments, while Ca2+ containing and acidic leaching solutions caused increased Sr2+ desorption. (C) 2010 Elsevier B.V.

AB  - Wide-spread use of metal-oxide varistors for non-linearity over-voltage protection results in a variety of possible working conditions. It is therefore essential to have a thorough insight into their reliability in various exploitation environments. The influences of temperature variation, aging and radiation exposure on metal-oxide varistors characteristics were investigated in this paper. Stable and effective over-voltage protection over a wide temperature range is always a desirable property, one which significantly contributes to overall system reliability. Behaviour of metal-oxide varistors in the temperature range from -50 degrees C to 150 degrees C was investigated. Aging caused by exploitation was investigated by applying 1000 consecutive double exponential over-voltage pulses to the varistors. Resistance of metal-oxide varistors to the radiation is of special interest in nuclear, military, and space technology. Radiation effects of californium-252 combined neutron/gamma radiation were examined. Voltage-current characteristics, voltage-resistance characteristics and the value of breakdown voltage were used to characterize metal-oxide varistors operation. Non-linearity coefficient, defined from the voltage-current curve, was also used as a parameter. Results are presented with the accompanying theoretical interpretations of the observed changes in metal-oxide varistors behaviour.

AB  - The aim of this work is examining the influence of the number of the activation-over-voltage pulses to the aging of over-voltage protection elements. Both non-linear (gas-filled surge arresters (GFSA), varistors, over-voltage diodes) and linear (capacitors-constituents of filters) over-voltage protection elements were tested. The instruments employed allow reliable measurements, 1000 consecutive activation were tested. The double-exponential current pulse (amplitude I-1(max) = 13 A, I-2(max) = 16 A, rise time T-1 = 8 mus, fall time T-2 = 20 mus) for non-linear elements and a double-exponential over-voltage pulse (rise time T-1 = 1.2 mus, fall time T-2 = 50 mus) of the amplitude U-1(max) = 320 V, U-2(max) = 480 V and U-3(max) = 640 V for capacitors were used. The experimental results show that the over-voltage diodes are the most reliable elements in view of characteristic modifications that are consequence of aging. However, it was observed that varistors, GFSA and capacitors undergo noticeable changes in characteristics. (C) 2002 Elsevier Science Ltd. All rights reserved.

AB  - In this study, we examine the reliability of erasable programmable read only memory (EPROM) and electrically erasable programmable read only memory (EEPROM) components under the influence of gamma radiation. This problem has significance in military industry and space technology Total dose results are presented for the JL 27C512D EPROM and 28C64C EEPROM components. There is evidence that EPROM components have better radioactive reliability than EEPROM components. Also, the changes to the EPROM are reversible, and after erasing and reprogramming all EPROM components are functional. On the other hand, changes to the EEPROM are irreversible, and under the influence of gamma radiation, all EEPROM components became permanently nonfunctional. The obtained results are analyzed and explained via the interaction of gamma radiation with oxide layers.
