By a News Reporter-Staff News Editor at Journal of Technology -- A new study on Thermal Science is now available. According to news reporting out of Bratislava, Slovakia, by VerticalNews editors, research stated, "The solidification/melting of cetane confined in nine silica glasses with specific controlled pores (CPG) with different pore sizes (r (p) ranging from 3.7-72 nm) has been studied. Samples with variable coefficient of filling of cetane were prepared and analyzed."
Our news journalists obtained a quote from the research from the Slovak Academy of Sciences, "Combining the indication of the evolving solidification heats (via differential scanning calorimetry, DSC) with the lifetime spectra of positron annihilation, the mechanism of filling of cetane molecules in the pores of the hosting silica glass matrices has been searched. Three independent solidification effects-three independent DSC peaks-were observed in each measuring cycle, namely one crystallization exotherm Rb of the bulk-cetane (if present) and two crystallization sub-peaks Rc1 and Rc2 of the confined cetane in the case of continuous cooling. The temperatures of both Rc1 and Rc2 effects decrease on decreasing the r (p) of the CPG matrix. The mutual relation between Rc1 and Rc2 has been analyzed."
According to the news editors, the research concluded: "The kinetics of all three steps of the solidification in the continuous-cooling as well as isothermal regimes have been specified."
