Easy. We’re not talking about a superhero here -- SM is a 44-year-old mother. And she’s fearless because she happens to be missing part of her brain: the amygdala(扁桃腺). Shaped like a pair of almonds sitting in the middle of your brain, the amygdala helps control fear and ...
Sm3+-doped amount of 0.02 mol,and the concentration quenching mechanism is the electric dipole–electric dipole interac-tion.The decay lifetime of the phosphors doped with different Sm3+ amounts was analyzed.The effect of the compensators Li+ on the emission intensity of the phosphor was also ...
It was first discovered that Curie temperatures of the hydrides of Sm 2(Fe,Ga) 17 compounds measured from the heating process are higher than that measured from the cooling process. The difference was denoted as Δ T c*. The correlation between Δ T c* and the structural stability of...
