Compared with the carbon-13 isotopic composition of the ubiquitous C32DPEP (DPEP, deoxophylloerythroetioporphyrin) the heavy but equivalent carbon-13 isotopic composition for the porphyrin structures 15(2)-methyl-15,17-ethano-17-nor-H-C30DP...
Predictive Modeling of Liquid Density and Surface Tension for Sustainable Aviation Fuels Using Nuclear Magnetic Resonance Atom Types [0.03%]
使用核磁共振原子类型对可持续航空燃料的液态密度和表面张力进行预测建模
Prescreening of sustainable aviation fuels (SAFs) is crucial for early stage development and ASTM D4054 evaluation. This study develops models to predict two key properties: temperature-dependent liquid density and surface tension of comple...
