Electrochemistry meets polymer physics: polymerized ionic liquids on an electrified electrode [PDF]
, 2021 Polymeric ionic liquids are emerging polyelectrolyte materials for modern electrochemical applications. In this paper, we propose a self-consistent field theory of the polymeric ionic liquid on a charged conductive electrode. Taking into account the conformation entropy of rather long polymerized cations within the Lifshitz theory and electrostatic and

Bouncing scalar field cosmology in the polymeric minisuperspace picture [PDF]
Mod. Phys. Lett. A 29 (2014) 1450169, 2014 We study a cosmological setup consisting of a FRW metric as the background geometry with a massless scalar field in the framework of classical polymerization of a given dynamical system. To do this, we first introduce the polymeric representation of the quantum operators. We then extend the corresponding process to reach a transformation which maps any

Advanced Engineering Materials, EarlyView., 2023 A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

Introduction: Polymerization [PDF]
Proceedings of the National Academy of Sciences, 2006 The Oxford English Dictionary defines polymer in its broadest sense as “a substance with a molecular structure formed from many identical small molecules bonded together.” Polymers, in their many diverse forms, are the remarkable materials constituting the essential “stuff” from which everything, from living organisms to computer components to common ...
