Dielectric characteristic of nanocrystalline Na0.5K0.5NbO3 ceramic green body
Dielectric spectroscopy was applied to porous nanocrystalline Na0.5K0.5NbO3 (NKN) ceramic green body, wherein influences of percolation effect and water adsorption at pore surface of the ceramic green body on dielectric response were examined over wide temperature (150 to 450 K) and frequency (100 Hz to 1 MHz) ranges. Dielectric permittivity of the ceramic green body is about 2–3 orders of magn...
متن کاملDirect observation of incommensurate structure in Mo3Si.
Z-contrast imaging, electron diffraction, atom-probe tomography (APT) and density functional theory calculations were used to study the crystal structure of the Mo3Si phase which was previously reported to have an A15 crystal structure. The results showed that Mo3Si has an incommensurate crystal structure with a non-cubic unit cell. The small off-stoichiometry in composition of the sample which...
متن کاملDirect observation of procedural skills (DOPS) evaluation method: Systematic review of evidence
Background: Evaluation is one of the most important aspects of medical education. Thus, new methods of effective evaluation are required in this area, and direct observation of procedural skills (DOPS) is one of these methods. This study was conducted to systematically review the evidence involved in this type of assessment to allow the effective use of this method. Methods: Data ...
متن کاملDirect observation of internal energy distributions of C5(-).
Photon induced decay of C5(-) has been measured in an electrostatic storage ring. The time dependence of the photo-enhanced decay is close to a 1∕t decay which indicates a thermal process. The deviation from the expected power of -1 is quantitatively explained by the small heat capacity of the anion. Measurements of the photo-enhanced decay at different storage times and photon energies allow a...
متن کاملInternal Structure Features of Asphalt Mixture for Field Samples
Asphalt mixture is heterogeneous in nature; therefore, macroscopic parameters alone cannot describe the mechanical behavior of the mixture. In recent years, the arrangement of the aggregate particles in terms of spatial and directional distributions, and contact points are considered as the internal structure of asphalt. The main purpose of this paper is to investigate the microstructural chara...
