Special Issue Information

Dear Colleagues,

The multifunctional properties of electronic materials have led to their use in a wide range of applications, including in electronics (microelectronics), magnetics (spintronics), dielectrics, optical components, and devices for energy conversion (thermoelectricity, solar cells), to name but a few examples. The understanding and optimization of their properties require the development of multi-scale and multi-physics approaches. Nowadays, with the rapid and extensive improvements in high-performance computing capabilities, atomic simulations (such as the first-principles approaches, molecular dynamics, Monte Carlo coupled or not with AI methods) are one of the fundamental building blocks to rationalize the design of compounds for targeted applications; for instance, application in microelectronics was one of the pioneering uses of these methods for bulk materials, or interface optimizations for different devices. This Special Issue aims to provide an overview of the current state-of-the-art of the applications of atomic modeling applied to the electronic materials being developed by both academia and industry. The contributions should illustrate the level of complexity of each method and the corresponding level of complexity of reachable phenomena and systems. Researchers are invited to contribute reviews and reports of their recent work in fields such as optoelectronics, dielectrics, magnetic and energy storage, and applications in conversion.

Anion Exchange Membrane (AEM) fuel cells have attracted growing interest, due to their encouraging advantages, including high power density and relatively low cost. AEM is a polymer matrix, which conducts hydroxide (OH) ions, prevents physical contact of electrodes, and has positively charged head groups (mainly quaternary ammonium (QA) groups), covalently bound to the polymer backbone. The chemical instability of the quaternary ammonium (QA)-based head groups, at alkaline pH and elevated temperature, is a significant threshold in AEMFC technology. This review work aims to introduce recent studies on the chemical stability of various QA-based head groups and transportation of OH ions in AEMFC, via modeling and simulation techniques, at different scales. It starts by introducing the fundamental theories behind AEM-based fuel-cell technology. In the main body of this review, we present selected computational studies that deal with the effects of various parameters on AEMs, via a variety of multi-length and multi-time-scale modeling and simulation methods. Such methods include electronic structure calculations via the quantum Density Functional Theory (DFT), ab initio, classical all-atom Molecular Dynamics (MD) simulations, and coarse-grained MD simulations. The explored processing and structural parameters include temperature, hydration levels, several QA-based head groups, various types of QA-based head groups and backbones, etc. Nowadays, many methods and software packages for molecular and materials modeling are available. Applications of such methods may help to understand the transportation mechanisms of OH ions, the chemical stability of functional head groups, and many other relevant properties, leading to a performance-based molecular and structure design as well as, ultimately, improved AEM-based fuel cell performances. This contribution aims to introduce those molecular modeling methods and their recent applications to the AEM-based fuel cells research community. Full article
