However, modelling the effect of agglomeration has not yet been discussed. Modelling such a complex material system can be undertaken by separating the filler rich section (agglomerates), which possess a higher filler concentration, from the non-percolating filler poor section. The effective (or ...

chemical shieldingbasis set effectGauge-independent atomic orbital (GIAO) method at Hartree-Fock (HF) and density functional theory (DFT) levels, respectively, was employed to calculate 19F NMR chemical shieldings of solid state alkaline-earth-metal fluorides MF2 (M = Mg, Ca, Sr, Ba). The ...
Carbon‐13 NMR studies. 73—carbon‐13 spectra of several 10‐methyl‐trans‐decalins. Further definition of the deshielding antiperiplanar γ effectThe 13C spectra of a series of 21 10-methyl-trans-decalins have been recorded to explore in greater detail the deshielding antiperiplanar 纬 ...
The effect pattern for LSR and time was maintained through different ethanol values; for the most part (the central range of values of time and LSR), yield increased linearly with LSR and time had almost no effect on extraction. Naturally, higher LSRs tended to favor the extraction of ...
