Abstract The aim of this work is to study the effect various talc rocks for preparation talc-based cordierite ceramics. Raw and sintered cordierite-based ceramic samples (1000-1375ºC 2 h) were characterized using XRD, XRF, TGA-DTG, laser PSDs, Archimedes method, SEM-EDAX dielectric relaxation spectrometer (DRS). Results show that impurity oxide contents, particle size mineralogical changes gree...
the effect of rare earth (re) elements, including ce and la, on the sorption properties of zr-co getters was investigated in this work. the phase evolution, microstructural characteristics of getter powders were studied by means of x-ray diffraction method, scanning electron microscopy (sem) and energy dispersive x-ray spectroscopy (eds). the nanostructured zr3co intermetallic compound has been...
conclusion adc, fa, and t2* values may quantitatively reflect the microstructural characteristics of np, therefore they could be used to detect the minimal changes of early ldd. results the adc, fa, and t2* values were different (p < 0.05) among different rois within the same disc or among corresponding rois in different level discs. while the average values of adc increased regularly with the ...
This paper aims at identifying the provenance of Goryeo celadons by understanding its microstructural characteristics, such as particles, blisters, forms and amount of pores, and the presence of crystal formation, bodies, and glazes and its boundary, using an optical microscope and scanning electron microscopy (SEM). The analysis of the reproduced samples shows that the glazed layer of the sher...
In the current paper, a low-Si aluminium alloy (1.4-2.4% Si) was used to fabricate a complex shape telecom component using Semi-Solid High-Pressure Die Cast (SSM-HPDC), process. Microstructure and fracture characteristics were investigated. The cast material exhibited microstructural inhomogeneity, in particular macrosegregation in the form of liquid surface segregation bands in addition to sub...
Doped BaSnO3 has arisen many interests recently as one of the promising transparent conducting oxides for future applications. Understanding the microstructural characteristics are crucial for the exploration of relevant devices. In this paper, we investigated the microstructural features of 0.001% La doped BaSnO3 thin film using both conventional and aberration corrected transmission electron ...
We are going to introduce the concept of stochastic 3D modeling of geometrically complex (disordered) microstructures as a tool for virtual materials testing, including applications to battery electrodes as well as to electrodes of fuel cells, and solar cells. Using stochastic 3D models, one can generate a large variety of stochastically simulated micrsotructures with little computational effor...
The positive relationship between hippocampal structure, aerobic fitness, and memory performance is often observed among children and older adults; but evidence of this relationship among young adults, for whom the hippocampus is neither developing nor atrophying, is less consistent. Studies have typically relied on hippocampal volumetry (a gross proxy of tissue composition) to assess individua...
