It can be regarded as an accurate alternative for experimental work in nano-science.
Introduction Since material properties in different scales are unlike, it is not accurate using material properties obtained from one scale to analyze the behavior of material in other scale.
Up to now numerous studies have been done, using MD for simulation of tension, compression and shear tests on single-crystal materials [4].

Preliminary Study of Activated Carbon Modified by Silica Aerogel Luo yajun1a, Yan qian1b, Zhou yongchao1c, He dengliang1d, Hu xiaoli1 e, 2 1Mianyang Normal University, Mianyang, Sichuan, 621010, China 2State Key Laboratory Cultivation Base for Nonmetal Composites and Functional Materials, Southwest University of Science and Technology, Mianyang，621010, China aluolaowu@126.com, b 331893521@qq.com, c 547657935@qq.com, d449011902@126.com, e441430968@qq.com Keywords: Silica Aerogel; Modified; Activated Carbon Abstract: Activated carbon was modified with silica aerogel by the Sol-Gel.
All the samples appeared an obvious weight loss steps under 140℃, it may be resulting from the water absorbed by material was take off; with temperature was raised to be about 380 ℃, it appeared an obvious weight loss step which lasted until 900 ℃, the weightlessness rate of activated carbon was the biggest.
