A new configurational bias scheme for sampling supramolecular structures [PDF]
, 2014 We present a new simulation scheme which allows an efficient sampling of reconfigurable supramolecular structures made of polymeric constructs functionalized by reactive binding sites. The algorithm is based on the configurational bias scheme of Siepmann and Frenkel and is powered by the possibility of changing the topology of the supramolecular ...

Hydrogen bonding exchange and supramolecular dynamics of monohydroxy alcohols [PDF]
arXiv, 2023 This Letter unravels hydrogen bonding dynamics and their relationship with supramolecular relaxations of monohydroxy alcohols (MAs) at intermediate times. Rheological modulus of MAs exhibit Rouse scaling relaxation of G(t) ~ t^(-1/2) switching to G(t) ~ t^(-1) at time tau_m before their terminal time.

Direct evidence of stress-induced chain proximity in a macromolecular complex [PDF]
, 2020 The mechanical properties of many supramolecular materials are often determined by non-covalent interactions that arise from an interplay between chemical composition and molecular microstructural organization. The reversible nature of non-covalent interactions gives supramolecular materials responsive properties that are otherwise difficult to obtain,

Adhesion and non-linear rheology of adhesives with supramolecular crosslinking points [PDF]
Soft Matter, Royal Society of Chemistry, 2016, 12, pp.7174-7185, 2016 Soft supramolecular materials are promising for the design of innovative and highly tunable adhesives. These materials are composed of polymer chains functionalized by strongly interacting moieties, sometimes called "stickers". In order to systematically investigate the effect of the presence of associative groups on the debonding properties of a ...

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Advanced Biology, EarlyView.Coacervation driven by liquid‐liquid phase separation (LLPS) of biopolymers has garnered increasing attention in biology since this leads to the formation of membraneless organelles capable of performing essential yet largely unknown functions. This review highlights recent advances in coacervates (artificial condensates) composed of low‐molecular ...

Advanced Materials Interfaces, EarlyView., 2023 The conduction band (CB) edge and surface state energy level of TiO2 nanoparticles shift downward with increasing Li+ concentration, which facilitates the charge‐transfer interaction between the molecules and the surface enhanced Raman scattering substrates. Abstract While the Lithium ion modification strategy is widely adopted in tuning the bandgap of

In-depth characterization of self-healing polymers based on π–π interactions
Beilstein Journal of Organic Chemistry, 2021 The self-healing behavior of two supramolecular polymers based on π–π-interactions featuring different polymer backbones is presented. For this purpose, these polymers were synthesized utilizing a polycondensation of a perylene tetracarboxylic ...
