The cubic garnet Li7La3Zr2O12 (LLZO) is a prototypical ceramic electrolyte for solid-state Li-ion batteries. While the electrochemical performance of LLZO well studied, thermodynamics formation not fully understood, and reliable synthesis phase-pure requires such knowledge. Here, we report high-temperature X-ray diffraction (HTXRD) study crystallization Al-doped from an amorphous gel with different amounts excess Li. Based on phases identified in precursor powders before during heating, net...
Rocking curve imaging (projection and section X-ray topography) has been used to study the generation propagation of defects at junctions between above seed crystals in mono-like silicon ingots. The images different kinds such as precipitates, dislocations twins integrated intensity, full width half-maximum peak position maps resulting from experiment have studied. qualitative quantitative information that can be extracted these maps, particular contrast various defects, is discussed. These...
The interfacial structure of coincidence site lattice grain boundaries in multi-crystalline silicon plays a decisive role their electrical behavior as revealed by high-resolution (scanning) transmission electron microscopy investigations. Considering only the global misorientation adjacent grains can lead to false correlation between structural and properties boundary. boundary habit plane well local deviations orientation that induce additional defects need be analyzed. Indeed, Σ9 {221}...
In this work, the kinetics of natural quartz reduction by Mg to produce either Si or Mg2Si was studied through quantitative phase analysis. Reduction reaction experiments were performed at various temperatures, times and SiO2 mole ratios 2 4. Rietveld refinement X-ray diffraction patterns used obtain distributions in reacted samples. SEM EPMA examinations evaluate microstructural change during reduction. The results indicated that rate slower a ratio than 4 same temperature, as illustrated...
The most efficient method to investigate nucleation phenomena is measure the undercooling temperature at beginning of solidification process since it gives information about whether or not a certain substrate favors heterogeneous nucleation. In this work suitable experimental setup has been designed and developed for study phenomena, where silicon droplet directly placed melted on substrate. melting‐solidification was filmed simultaneously measured by monochromatic bichromatic pyrometers....

The present study is dealing with the corrosion of copper coated nanocrystalline nickeltungsten coating. Different plating bath compositions and conditions were used in order to produce nickel-tungsten coatings different tungsten content 30%, 40% 50% wt, a thickness 20 μm. resistance alloy was examined by potentiodynamic polarisation technique NaCl solution (0.03 M, 0.3 M 1 M) as function pH (3, 7, 10) temperature (7°C, 30°C, 40°C) solution. It has been found that value did not seem...
The present paper deals with the deposition and characterisation of zinc oxide coatings on mild steel substrates by cathodic electrolytic via a 0·1M nitrate aqueous solution. influence parameters, such as applied potential time, growth was also investigated. protection efficiency these examined potentiodynamic polarisation technique in 0·3M NaCl solution (pH = 5·5, T 25°C). obtained results showed that ZnO improve anticorrosion performance steel.
