Predicted field-induced hexatic structure in an ionomer membrane [PDF]
, 2008 Coarse-grained molecular-dynamics simulations were used to study the morphological changes induced in a Nafion$^{\tiny \textregistered}$-like ionomer by the imposition of a strong electric field. We observe the formation of novel structures aligned along the direction of the applied field.

SkyMapper Filter Set: Design and Fabrication of Large Scale Optical Filters [PDF]
, 2011 The SkyMapper Southern Sky Survey will be conducted from Siding Spring Observatory with u, v, g, r, i and z filters that comprise glued glass combination filters of dimension 309x309x15 mm. In this paper we discuss the rationale for our bandpasses and physical characteristics of the filter set. The u, v, g and z filters are entirely glass filters which

Current aspects and prospects of glass ionomer cements for clinical dentistry
Yeungnam University Journal of Medicine, 2020 Glass ionomer cement (GIC) is a tailor-made material that is used as a filling material in dentistry. GIC is cured by an acid-base reaction consisting of a glass filler and ionic polymers.

Australian Endodontic Journal, EarlyView.ABSTRACT This study investigated the solubility of AH Plus Bioceramic sealer (AHPB), the ion release, and the modification of surface characteristics compared to AH Plus (AHP). Solubility was examined according to ISO guidelines in deionised water and phosphate buffer saline (PBS) for 3 months.

Ionomer structure and component transport in the cathode catalyst layer of PEM fuel cells: A molecular dynamics study [PDF]
J. Chem. Phys. 160, 044910 (2024)The transport of water and protons in the cathode catalyst layer (CCL) of proton exchange membrane (PEM) fuel cells is critical for cell performance, but the underlying mechanism is still unclear. Herein, the ionomer structure and the distribution/transport characteristics of water and protons in CCLs are investigated via all-atom molecular dynamics ...
