On the subject of stars and linear chains, the same authors have employed MC calculations based on Bishop and Clarke s pivot algorithm to study the validity of scaling and group renormalization theories of these interesting molecules. Dimensions and intrinsic viscosities were also calculated. - ... [Pg.183]

To avoid rapidly increasing numbers with molecule dimension and branching, relative atomic moments (RAMs) are defined, normalizing each atomic moment as ... [Pg.386]

The three M41S family silica phases obtained with cationic surfactants in a basic medium represent the primary set of principal mesoporous structures. The observed phase transitions are attributed to changing surface curvature resulting from decreasing packing factor, g, which is related to the surfactant molecule dimensions and defined as [35] ... [Pg.98]

The use of nanomaterials for enzyme immobilization may offer some advantages regarding enzyme stabilization, control of the pore size to protein molecule dimensions, multiple sites for interaction, and reduced mass-transfer limitations... [Pg.355]

Figure 6. Experimental Figure 6. Experimental <D(r) contour plots including the contributions of all atoms in the molecule. Dimensions and contour interval as in Figure 3. (a) Plane of the thiophene ring, minimum contour -60 kcal/mol. To be compared with Figure 3(a). (b) Plane of the tetrazole ring, minimum contour -80 kcal/mol. To be compared with Figure 4(a).
A related factor is shape varying the gas molecule dimensions affects the value of fl for a highly nonspherical (oblate or prolate) ion more than for its near-spherical isomer, because the former has greater surface area (Figure 1.12). In the above example of ubiquitin ions, H in N2 exceeds H in He by 10% for compact pseudonative conformers (at z = 6-9) but by 20% for denamred ones with highly... [Pg.20]

A method that has won general favor is gel permeation chromatography. Basically, polymer samples are separated by size of molecule. The separation is accomplished by using beads of a rigid, porous gel whose pores are about the same size as polymer molecule dimensions (see Fig. 1-21). [Pg.24]

The conditions of the formation of the solution of such kind for channel inclusion compounds are simplified substantially and seem to be reduced to those of the formation of the individual clathrates, i.e. to the conformity of the guest molecules dimensions to the cross-section of the clathrate framework channel (for urea for thiourea 6,9-7j4A). [Pg.191]

Figure 8.9 Number of vibrational modes to be considered increases steeply with molecule dimension, for example, coumarin C153. Figure 8.9 Number of vibrational modes to be considered increases steeply with molecule dimension, for example, coumarin C153.
An apparent negative inaccessible displaceable volume was obtained for several cores when the brine-flush portion of the flow test was evaluated using Eq. 1. The three cores exhibiting this behavior (Cores 42, 48, and 73, Table 2) ate of sufficiently low permeability that a substantial fraction of the pores could have diameters smaller than nominal polymer-molecule dimensions in solution.This could cause plugging of the tighter pores, with trapping of subsequent flowing polymer. Release of... [Pg.258]
