In 1985, Baumeister et al. [113] presented the crystal structure of 4-cyano-phenyl-tran5-4 -[(trfln5-4-n-butylcyclohexyl)methyl]cyclohexanoate (CBMC). The molecular structure of this compound is shown in Fig. 22. The molecules... [Pg.175]

Often the ratio of Henry coefficients, related to adsorption at zero loading, is used for predicting the selectivity of adsorption for mixtures. The ratio of Henry coefficients for linear and mono-branched alkanes with carbon number n = 5-8 are summarized for various zeolites in Figure 13.10 [15]. The Henry coefficient ratios were 1 for FAU, 2 for BEA, MOR and MFI, 6-9 for TON and 10-14 for MTT. Interestingly, CBMC simulations suggest that the ratio of Henry coefficients, actu-... [Pg.413]

The impact of the biased chain regrowth method on the efficiency of MC simulations depends significantly on the nature of the polymer models. Specifically, the ability of the CBMC method to generate unique low-energy... [Pg.259]

The JW procedure was used in an ESMC simulation study of 38- and 54-residue (210) lattice polypeptide models [19,22] described above. Figure 5 shows the computed entropy function and its standard deviations obtained by the ESMC method with the JW procedure (including also the CBMC technique). The standard deviations of the computed entropy func-... [Pg.262]

The value of S(Q) at zero Q value cannot be determined experimentally on the same instrument that is used to measure diffusivities there are not enough points at small Q in Fig. 8b. However, the S(Q) scale, which is given in Fig. 8b in arbitrary units, can be renormalized. At infinite dilution, S(0) should be equal to one (hke in a gas), and sorption thermodynamics also imply that the thermodynamic correction factor should be equal to one, so that Eq. 38 will be fulfilled. On the other hand, at high concentrations, F increases while S(0) goes down. In Fig. 8b, r is equal to 6.6 for a concentration of 14 CF4 per u.c. so that S(0) should go down to 0.15. A more quantitative analysis has been recently performed for n-hexane and n-heptane in sihcalite [36] where the inverse of the thermodynamic factor, calculated from S(Q) was found to be in good agreement with configurational-bias Monte Carlo (CBMC) simulations. [Pg.227]
