Pectin Mucilage Adhesion on a Flat Substrate: A Molecular Simulation Approach to Plant-Seed Adhesion.

We investigate the adhesion of pectin-mucilage-coated seeds to substrate surfaces, focusing on the effect of water content. It is known that the adhesion of pectin mucilage increases with water loss, eventually dropping to zero beyond a certain point. To explore this phenomenon, we develop and parametrize a coarse-grained many-body dissipative-particle dynamics (MDPD) model.

Monte Carlo simulation of molecular and structural properties of random copolymer thin films.

Molecular and structural properties of random copolymer thin films were studied by Monte Carlo simulation of coarse-grained copolymer model on the high coordination lattice. Random copolymer thin films with 50% comonomer fraction with varied interaction strength between comonomer units were studied. Intramolecular interaction was represented by Flory's rotational isomeric state (RIS) model of polyethylene (PE).

Viscoelastic Relaxation of Polymerized Ionic Liquid and Lithium Salt Mixtures: Effect of Salt Concentration.

Polymerized ionic liquids (PILs) doped with lithium salts have recently attracted research interests as the polymer component in lithium-ion batteries because of their high ionic mobilities and lithium-ion transference numbers. To date, although the ion transport mechanism in lithium-doped PILs has been considerably studied, the role of lithium salts on the dynamics of PIL chains remains poorly understood. Herein, we examine the thermal and rheological behaviors of the mixture of poly(1-butyl-3-vinylimidazolium bis(trifluoromethanesulfonyl)imide (PC-TFSI)/lithium TFSI (LiTFSI) in order to clarify the effect of the addition of LiTFSI.
