Magnesium alloys are ideal lightweight materials; however, their applications are extremely limited due to their low strength, poor ductility, and weak corrosion resistance. In the present study, a friction stir processing (FSP) treatment was employed to optimize the mechanical properties and corrosion...
The {101¯2} twinning exhibits a relatively strong size effect regarding the twin nucleation stress (n = 0.7). The nucleation mechanism of the {101¯2} twin assessed by in-situ TEM directly showed that the pile-up of prismatic <a> dislocations acts as local stress concentration for...
Nanoparticles prepared by the sol-gel route exhibit mainly visible luminescence whereas their UV emission is weak. On the contrary, highly crystalline ZnO displays strong band-edge luminescence. In our study, only a weak UV emission peak at ∼380 nm was observed when the ZnO QDs where excited...
When cyclization does not occur under these conditions, cyclization may be affected by stirring amide 9 in the presence of a weak base such as piperidine in a suitable solvent such as EtOH at a temperature between room temperature and reflux. An alternate synthesis to α,β-unsaturated ketone ...
The inverse pole figure acquired in 3D space reference X0, Y0, and Z0, displays near random to weak patterns of bulk CPO of the grains with several orientation maxima crystallographic preferred orientation (CPO) patterns, with numerous orientation maxima at (100), (110), and (111) (Figure ...
The lattice energy of Mg(NO3)2 is 2429.51 kJ·mol−1 [26] and is presumed to exhibit weak salt dissociation, resulting in low room temperature conductivity. Using the same relationship, the conductivity can be said to be affected by the temperature. Figure 2c illustrates the graph log σ...
Though that first impression weak- ens slightly on careful examination, its nonetheless a stand-out product, highly recommended, and a promising initial release for WFRs line of campaign and adventure supplements. Graphic design: The graphic presenta- tion is very satisfying. The cover ...
The Algonquins crossed over to Brooklyn where they had a strong base, made strong by the twelve-foot giant, Anenak, who lived and all but ruled there. When Olaf’s s ship arrived in the East River, Kirstie had them row first to Brooklyn. It would be dangerous, but they would need ...
“Your home?” The tall man laughed. The swords rang once against each other and the men began to circle to gauge their opponent and look for a weak point to attack. Clearly, both knew the craft, and well. “Of course it is my home. I took it. I built it,” Gerraint said. The...
