[Pg.421] WebSep 7, 2007 · Calculation of the maximal diameter for P5K2 using the Flory dimension for 5-kD PEG gives a molecule with D max ~ 190 Å (i.e., Hb diameter = 70 Å + PEGs, 2 × 60 Å), thus providing an estimation for the mushroom conformation of the PEG chains on P5K2 that fold to ~60% of their full Flory dimensions.

WebA flexible polyanion is more likely to adopt an extended conformation suitable for templating than is a flexible neutral polymer, which is more likely to fold. 21 The Flory dimension of a polyelectrolyte (like DNA), other things being similar, is much larger than that of a biopolymer with, for example, a repeating dipole. 22 As noted above ...
WebNational Center for Biotechnology Information WebThe net osmotic swelling pressure of the hydrogel, Π, is then given by Flory-Rehner theory ( 26 – 33) Π = Πmix + Πel (3) This osmotic swelling pressure is initially large, and solvent infiltrates the hydrogel network; however, as swelling progresses, Π continually decreases and eventually reaches zero.
WebApr 6, 2024 · We consider a phase-field model which describes the interactions between the blood flow and the thrombus. The latter is supposed to be a viscoelastic material. The potential describing the cohesive energy of the mixture is assumed to be of Flory-Huggins type (i.e. logarithmic). This ensures the boundedness from below of the dissipation … WebFlory-Kriegbaum which is a thermodynamic theory for dilute polymer solutions.
