Findings from Carnegie Mellon University Provides New Data on Fullerenes

February 21, 2014



By a News Reporter-Staff News Editor at Energy Weekly News -- A new study on Fullerenes is now available. According to news originating from Pittsburgh, Pennsylvania, by VerticalNews correspondents, research stated, "Molecular dynamics simulations are used to predict the energy accommodation coefficients (EACs) between the noble gases He, Ne, and Ar and the outside of single-walled carbon nanotubes (CNTs) with diameters between 0.41 and 6.10 nm at a temperature of 300 K. The EAC increases monotonically with CNT diameter and approaches the value predicted for graphene."

Our news journalists obtained a quote from the research from Carnegie Mellon University, "The EAC also increases monotonically with gas atom mass. The CNT EAC data collapse to a linear trend when they are normalized by the graphene EAC and plotted versus the depth of their potential energy well on the CNT normalized by that for graphene."

According to the news editors, the research concluded: "The EACs are used to estimate that the thermal boundary conductance between noble gases and graphene will be of order 0.1 MW/m(2).K at a gas pressure of 1 atm, corresponding to a gas Kapitza length of order 100 nm."
