生物进化基本常识：一定范围内，选择压力越大，要么进化的越快来适应这种压力，或者直接被淘汰。

Shape-Controlled Synthesis of Colloidal Platinum Nanoparticles
Temer S. Ahmadi, Zhong L. Wang, Travis C. Green, Arnim Henglein, Mostafa A. El-Sayed *

The shapes and sizes of platinum nanoparticles were controlled by changes in the ratio of the concentration of the capping polymer material to the concentration of the platinum cations used in the reductive synthesis of colloidal particles in solution at room temperature. Tetrahedral, cubic, irregular-prismatic, icosahedral, and cubo-octahedral particle shapes were observed, whose distribution was dependent on the concentration ratio of the capping polymer material to the platinum cation. Controlling the shape of platinum nanoparticles is potentially important in the field of catalysis.
