By a News Reporter-Staff News Editor at Physics Week -- Investigators publish new report on Acyclic Hydrocarbons. According to news reporting originating in Guangdong, People's Republic of China, by VerticalNews journalists, research stated, "The straight chain n-alkanes based paraffin phase change materials (PCM) have been widely investigated by experimental and numerical methods. This paper presents a study from molecular point of view to discuss the self diffusion and heat capacity of n-alkanes and their binary mixtures based PCM with molecular dynamics (MD) simulation method."
The news reporters obtained a quote from the research from the South China University of Technology, "Four PCM systems, n-nonadecane, n-tetracosane, n-nonadecane and n-tetracosane (1/1) and n-nonadecane and n-tetracosane (3/1), were constructed with amorphous structure and periodic boundary conditions. The results showed that the phase transition behaviors of the PCM could be determined according to the variation of simulated self diffusion coefficient and isobaric heat capacity."
According to the news reporters, the research concluded: "Comparisons of isobaric heat capacity between the MD and experimental results showed reasonable agreement below 353 K. The strength and width of radial distribution functions indicated the mobility of the alkane chains that is helpful for further understanding the diffusion property."
