MS建立具有一定粗糙度孔徑的介孔分子篩
|
|
|
如何使用MS建立具有一定粗糙度孔徑的介孔分子篩模型呢?主要是在孔道上如何體現(xiàn)粗糙度? 比如下面這段話的描述 The surface roughness was controlled by introducing a known number of physical deformations into the pore surface. Physical deformations were created by removing the atoms from randomly selected spherical areas, approximately 4-6 Å in diameter, from the entire cell until the skeletal density was about 2.2 g/cm3. The diameters of these spherical voids were chosen from a Gaussian distribution with a mean of 5 Å and a standard deviation of 1 Å 如何在MS里建立的介孔孔道中體現(xiàn)Guassian分布這些小球呢? |

我也很想知道這個怎么做,曾經(jīng)看到一個有名的分子模擬文獻,講的就是不同粗糙孔的介孔分子篩吸附性能。 我猜是做好母體,然后手動刪除內(nèi)孔,調(diào)整不同的粗造度。但是具體怎么算出粗糙度,不知道怎么弄。。 mark一下,繼續(xù)關注。 |
