We establish a new model based on fractal theory and cubic spline interpolation to study the effective thermal conductivity of isotropic porous silica low-k materials. A 3D is introduced describe structure xerogel hybrid materials (such as methylsilsesquioxane, MSQ). Combined with structure, more suitable medium approximation developed MSQ Cubic for fitting discrete predictions from used obtain continuous function versus porosity. Compared other common models, predicted by our presents...
Depth profiled positronium (Ps) annihilation lifetime spectroscopy (PALS) is an extremely useful probe of the pore characteristics in nanoporous low-dielectric (low-k) constant thin films. PALS has also been considered as a potential to investigate diffusion barrier integrity and structural changes porous low-k films during their integration with Cu. Hence, it essential understand behaviour positronium/Cu atoms In this work, based on fact that materials possess statistical self-similarity,...
In this work, we propose a new model for the dielectric constant and thermal conductivity, apply it to design of composites with low high conductivity based on fractal theory effective medium theory. particular, use prepare porous AlN/BN/SiOC in different component fractions. We successfully synthesize ceramic samples constants [Formula: see text] ([Formula: text]). These results indicate that proposed is valid.
A renovated shielding gas apparatus was successfully used to protect the laser-welded pool during Nd:YAG laser welding process of a particulate SiC-reinforced magnesium alloy composite. Laser carried out by preplacing thin nano-Ni-powder onto seam surface. parameters, such as beam diameter and scanning velocity, were optimized obtain sound welded seam. The microstructure elemental distribution analyzed employing electron microscope incorporating energy dispersive X-ray diffraction analysis....
