Review of common magnetic and related investigations on the uranium semimetallics and the rare earth intermetallics and their hydrides carried out by K.P. Belov, his students and coworkers as well as by the scientists from Wroc³aw (W. Trzebiatowski's students) is presented.
A significant barrier to the clinical translation of systemically administered therapeutic nanoparticles is their tendency to be removed from circulation by the mononuclear phagocyte system. The addition of a targeting ligand that selectively interacts with cancer cells can improve the therapeutic efficacy of nanomate…
The corrosion resistance of liquid phase sintered (LPS) alumina ceramics in aqueous environments strongly depends on composition and chemistry of grain boundary glass formed during sintering. The chemical durability of model alumino-silicate glasses with various contents of CaO in aqueous solutions was therefore evalu…
Values for the changes in the electrostatic energy stored in a dielectric as a conducting discharge channel propagates through a dielectric have been calculated using a basic charge simulation model. This approach is based on: first deriving the distribution of discrete charges required to generate an equipotential su…
AmorphousAl2O3ZrO2powders were synthesized by citric acid gel process. The effects of molar ratio of citric acid to total metal ions concentration and the calcined powders with CA/M=2:1 were investigated through XRD and SEM analysis. Thermal behavior of the dried gel with CA/M=2:1 was studied by DSC/TG. Amorphous Al2O…
In this study,we prepared two kinds of glass frits include CAS and Bi-based glass frit as inorganic binders.Analysis the thermal properties and particle size of the prepared glass frits through DTA analyzer and laser mastersizer.Through sessile drop to research the wetting property between the prepared glass frits and…
PURPOSE: In external beam radiotherapy, the presence of metal implants such as hip prostheses causes significant streak artifacts in planning images, thus affecting the accuracy of target and critical organ delineation. The purpose of this study is to evaluate the improvement of image quality and impact on accuracy of…
A facile one-step microemulsion method was applied to introduce a Mo promoter into a [email protected] catalyst with a yolk-shell structure ([email protected]). Mo atoms were inserted in the silica shell framework to form SiMoOx species instead of a typical NiMo alloy. It was found that the formation of SiMoOx signifi…
The selective wet etching characteristics of AgInSbTe film as a new thermal lithography material were studied with ammonium sulfide solution as etchant. Influences of vacuum-annealing temperature, etchant concentration and wet etching time on selective wet etching characteristics of the amorphous and crystalline AgInS…
In this paper, the effect of sintering temperature on microstructure and donor solid solubility of Nb-doped TiO2varistor ceramic is investigated. SEM and EDXS were carried out to study the microstructure and chemical compositions of TiO2grain. The results show that the TiO2sample sintered at 1350°C have better microst…
Purpose: To study the effect of geometrical and electrical parameters on focal spot size (FSS) of TiO2 nanotube field emission X-ray tube. The X-ray tube parameters were optimized to achieve the smallest FSS for different cathode sizes and anode voltages. Methods: The simulations were performed using the industry stan…
Alumina (Al2O3) and Al2O3-based ceramics are candidate wear-resistant materials for many applications. In the past decades, the friction and wear behaviors of Al2O3 and Al2O3-based ceramics in dry sliding and lubricated conditions have been extensively investigated. In dry sliding, surface modification of Al2O3 and Al…
Lead selenide has been the subject of considerable interest because of its potential applications in many fields. In this paper, the synthesis of lead selenide nanostructures is described. The Morphologies of as prepared lead selenide nanostructures are summarized. And the applications and prospects of lead selenide i…
In this paper, pure ZnO nanospheres and IO3- ions doped ZnO nanospheres were prepared by heating under reflux with zinc acetate and diethylene glycol as raw materials, and the ZnO dye-sensitized solar cells (DSCs) were prepared. The influences of reaction time and IO3--ions dope on ZnO properties were studied. DSCs pr…
The influence of magnetoelectric interactions on the magnetic structure, flexomagnetoelectric polarization and magnetization in thin multiferroics film has been investigated. The correlation between antiferromagnetic domain structure and ferroelectric domain pattern has been revealed. It has been shown the asymmetry o…
Abstract In Germany radon exposure at certain workplaces has been regulated by the Radiation Protection Ordinance since 2001. However in Bavaria studies have been conducted since 1996. The radon exposure of all staff concerned was estimated and thereby several companies were identified where the exposure exceeded 6 mS…
Nano-Cordierite powders used for high frequency chip inductors (MLCIs) were prepared by the sol-emulsion-gel method. The samples derived from these powders could be sintered at 900°C to be cordierite ceramics having a low dielectric constant and dielectric loss (ε=3.18, tgδ=0.00011; 1GHz). Effects of precursor concent…
In order to compare the absorbing properties of different microwave-absorbing agents and their mixture, this paper has selected two typical microwave-absorbing agents which respectively are carbon fiber resistance microwave-absorbing agents and ferrite magnetism microwave-absorbing agents, and took them as monolayer a…
Abstract Summary: Aqueous dispersions of diblock copolymer micelles with homogeneous hydrophobic core (polystyrene) and heterogeneous amphiphilic corona from ionic N‐ethyl‐4‐vinylpyridinium bromide (EVP) and hydrophobic 4‐vinylpyridine (4VP) units have been prepared at pH 9. The structure and dispersion stability of m…
Purpose: To use the Monte Carlo code PENELOPE to study attenuation and tissue equivalence properties of a‐Al2O3:C for OSL dosimetry. Methods: Mass attenuation coefficients of α‐Al2O3 and α‐Al2O3:C with carbon percent weight concentrations from 1% to 150% were simulated with PENELOPE Monte Carlo code and compared to ma…
