原文如下：
The final critical ingredient is the addition of Cl- ,Br- ,orFe+3 to the PVP—Ag solution to produce nanocubes, right bipyramids, or nanowires of silver, respectively.
为什么要掺杂其他离子来控制形貌？
PVP interacts more strongly with silver atoms on
{100} facets than with those on {111} facets
如何知道pvp到底跟ag晶体哪个晶面结合力强？通过什么方法测定的？
