Polymer chain length calculation
WebPolymers consist of repeat units (monomers) chemically bonded into long chains. Understanding the physical properties of a polymer (such as mechanical strength, sol … Web4 shows the probability of a polymer chain being in a certain sized cluster, where the cluster size is measured as a fraction of the finite sized simulation, as a function of polymer charge ratio, which is defined as the ratio of the number of positive charges to the number of negative charges in polymer clusters (the system is electrically neutral due to counterions).

WebThe high hydrolytic activity is explained by the fact that AmyC has a considerably shorter catalytic loop (residues 213-220) not reaching the acceptor side. Secondly, in AmyC, the tryptophan residue (W 246) near the active site has its side chain buried in the protein interior, while the side chain is at the surface in Tk1436 and Tt1467 GBEs. WebThe comb polymer has side chain length N sc = 3 beads, and side chains are attached every l sc = 2 backbone bead. ...

Since P e is apparently a polymer-independent constant, Eq. (25.10) suggests that the tube diameter and packing length are proportional, and the constant of proportionality thus has the empirical temperature dependence [1,2]:
WebLn(Ⅲ) cations are linked by carboxylate groups from (bppc) – ligands to form one-dimensional ring chains, which are further connected by the carboxylate groups of (bppc) – and (suc) 2– ligands to extend a 2D layer structure. These coordination polymers display the characteristic emission bands of Ln(Ⅲ) ions in the solid state.
