Equilibrium conformation of polymer chains with noncircular cross section
Shumin Zhao, Shengli Zhang, Zhenwei Yao +1
In this paper we derive the general equilibrium equations of a polymer chain with a noncircular cross section by the variation of the free energy functional. From the equilibrium e…

Buckling and competition of energy and entropy lead conformation of single-walled carbon nanocones
Shengli Zhang, Zhenwei Yao, Shumin Zhao +1
Using a continuum model, expressions for the elastic energy, defect energy, structure entropy, and mixing entropy of carbon nanocones are proposed analytically. The optimal conform…
