Toz Metalurji̇si̇ Yöntemi̇ İle Alümi̇nyum Köpük Üreti̇mi̇ Procuction of Al Foams by Powder Metallurgy Route

In this study pure Al and pre-alloyed Al alloy powders (Alumix 231Al-Cu %2.5-Mg %0.5–Si %14) with or without reinforcing elements were used to produce classical Al foam or spherical Al foam with various production parameters by using powder metallurgy route and the results obtained have been discussed. Al2O3 and SiC particles were used as reinforcing elements and TiH2 powders were used as foami...

Zwitterionic Si-C-Si-P and Si-P-Si-P four-membered rings with two-coordinate phosphorus atoms.

مشخصه‌یابی ‌ساختارهای دورآلائیده وارون p-Si/SiGe/Si با روشهای پرتو X و الکتریکی

In this work, the epitaxially grown, lattice–matched p-Si/Si1-xGex/Si inverted remote doped structures have been characterized using X-ray and electrical techniques. The Si cup layer thickness () and Ge content (x) have been determined from computer simulation of intensity and angular sepration of (004) peaks observed in the X-ray diffraction pattern due to misorientaion of corresponding Bragg ...

Model and Methods Energy Hamiltonian.To extend a structure-based model to systems with multiple basins, we modified the contact map and the dihedral angles. Note that all the residue indexes are rearranged from 1 to 366 in the model. To include the side chain dynamics on the conformational change of enzyme, we developed a coarse-grained model in which each amino acid is represented by one or tw...

Characterization of Si/Si 1 -,Ge,/Si quantum wells by cathodoluminescence imaging and spectroscopy

Cathodoluminescence (CL) imaging and spectroscopy have been used to characterize fully strained SiGe quantum wells grown on Si. At T-5 K, the CL spectra contain only band edge luminescence features. Monochromatic imaging with the no-phonon line attributed to the bound excitons in the quantum well, has shown that the distribution of the luminescence from the wells is not uniform. The thinnest we...
