Reports on Multiwalled Carbon Nanotubes from Bauhaus University Provide New Insights (Binding energy and mechanical stability of single- and multi-walled carbon nanotube serpentines)

By a News Reporter-Staff News Editor at Physics Week -- Investigators discuss new findings in Multiwalled Carbon Nanotubes. According to news reporting from Weimar, Germany, by VerticalNews journalists, research stated, "Recently, Geblinger et al. [Nat. Nanotechnol. 3, 195 (2008)] and Machado et al. [Phys. Rev. Lett. 110, 105502 (2013)] reported the experimental and molecular dynamics realization of S-like shaped single-walled carbon nanotubes (CNTs), the so-called CNT serpentines. We reported here results from continuum modeling of the binding energy. between different single- and multi-walled CNT serpentines and substrates as well as the mechanical stability of the CNT serpentine formation."

The news correspondents obtained a quote from the research from Bauhaus University, "The critical length for the mechanical stability and adhesion of different CNT serpentines are determined in dependence of EiIi, d, and gamma, where EiIi and d are the CNT bending stiffness and distance of the CNT translation period. Our continuum model is validated by comparing its solution to full-atom molecular dynamics calculations."

According to the news reporters, the research concluded: "The derived analytical solutions are of great importance for understanding the interaction mechanism between different single- and multi-walled CNT serpentines and substrates."
