The main obstacles that hinder the vapor growth of TMDs at the 2D limit to grain sizes typically <10 nm consist of the precise control of the nucleation sites and the growing rate of the grains. These can be addressed by using a high-density of Au QD seeds and a low mass flow rate...
Samples of Nd-Fe-B alloys, which have been the main hard-magnetic materials with the highest magnetic energy since the end of the 1980s, are investigated. Magnets based on them are obtained by liquid-phase sintering or spin coating. In this article, wetting of the Nd 2 Fe 14 B grains ...

and that happens at not so-large deformations. This type of GBS, accommodated by the process described above, is termed as ‘Rachinger grain boundary sliding’. When this occurs, the average grain size and shape remain unchanged after large deformation values being the main feature of this ...
At the meantime, the time scales tend to become longer and it indicates that the changes of the grain output of Jiangsu province become steady step by step ; 2) the grain output has the 13 years and the 25 years main periods from the wavelet variances analysis, and the 25 years period ...
I knew by the feeling in the room that the situation was grave. I asked his name. He told me it was Billy and that I did a few simple magic tricks for him. As I stepped back to say goodbye, he asked me “Ronald, would you hold me?”At such a simple request, my heart ...
