DOI: 10.1016/j.bpj.2018.03.035

Abstract: Functional RNAs can fold into intricate structures using a number of different secondary and tertiary structural motifs. Many factors contribute to the overall free energy of the target fold. This study aims at quantifying the… read more here.

DOI: 10.1016/j.molliq.2020.114043

Abstract: Abstract In the present work we accomplished analysis of interplay of enthalpic (van der Waals and electrostatic) and entropic (solvophobic) factors into the aggregation process of fullerene C60 in solution. We showed that in order… read more here.

DOI: 10.1021/acsmacrolett.2c00019

Abstract: Using fluorescence microscopy and single-particle tracking, we have directly observed the dynamics of λ-DNA trapped inside poly(acrylamide-co-acrylate) hydrogels under an externally applied electric field. Congruent with the recent discovery of the nondiffusive topologically frustrated dynamical… read more here.

DOI: 10.1038/s42005-019-0118-8

Abstract: The entropic force is one of the most elusive interactions in macromolecules. It is clearly defined theoretically, but practically difficult to evaluate, thus restricting our knowledge of it often to a qualitative level. Here, we… read more here.

DOI: 10.3390/e22040491

Abstract: There are entropic functionals galore, but not simple objective measures to distinguish between them. We remedy this situation here by appeal to Born’s proposal, of almost a hundred years ago, that the square modulus of… read more here.
