The famous Kramers rate theory for diffusion-controlled reactions has been extended in
numerous ways and successfully applied to many types of reactions. Its application to …

Natural elastomeric fibres play central structural and functional roles in a variety of tissues
produced by many organisms from diverse Phyla. Most of these fibres feature amorphous …

Protein chains undergo conformational diffusion during folding and dynamics, experiencing
both thermal kicks and viscous drag. Recent experiments have shown that the …

Frictional effects due to the chain itself, rather than the solvent, may have a significant effect
on protein dynamics. Experimentally, such “internal friction” has been investigated by …

Protein folding and dynamics are governed by an intricate interplay of thermal and viscosity-
mediated effects. The solvent viscosity contributes to the frictional drag in protein dynamics …

Recent experiments showed that the reconfiguration dynamics of unfolded proteins are often
adequately described by simple polymer models. In particular, the Rouse model with …

Recent work has highlighted an intimate link between the internal friction of single
biopolymers and dynamics on an underlying energy landscape of conformational change …

We have studied in silico the effect of proline, a model cosolvent, on local and global friction
coefficients in (un) folding of several typical alanine-based α-helical peptides. Local friction …

This review's main objective is to discuss some physico-chemical features of
polysaccharides as intrinsic determinants for the supramolecular structures that can …

Polysaccharide polymers like pectin can demonstrate striking and reversible changes in
their physical properties depending upon relatively small changes in water content. Recent …
