Editorial: Reviews in batteries and electrochemistry volume II

A central theme is safer battery design through material and structural innovation. Myeong et al. introduce a fire-extinguishing current collector coated with melamine polyphosphate (MPP) for lithium-ion batteries. Their work demonstrates that integrating a flame-retardant layer directly onto the Al current collector c...

Combustion behavior of various biomass wastes pellet fuel: Thermogravimetric analysis and ash fusion characteristics

This study compared rapeseed straw (RS), flower waste (FW), and tobacco straw (TS) in terms of fuel properties, combustion behavior, kinetics, and ash fusion characteristics. Proximate and ultimate analyses, scanning electron microscopy (SEM), thermogravimetric analysis (TGA), X-ray diffraction (XRD), ash fusion tests,...

Data-Driven Prospective Design of Phase-Inversion Conductive Polymer Membranes

Conductive polymer membranes combine separation and electrical functionality, but their design remains challenging because performance emerges from coupled effects of composition, fabrication, and operating conditions. Here, we assembled 396 membrane records from 77 publications and developed target-specific machine-le...

Computational analysis of space–time fractional three-dimensional nonlinear fluid flow models using a Laplace transform-based iteration technique

Role of Structural Disorder on Phonon Transport and Thermal Conductivity in Li 6 PS 5 Br

ABSTRACT Sulfidic solid electrolytes pose a promising material class for enabling solid‐state batteries. While their defect chemistry and ion transport have been studied extensively, thermal transport and its interplay with ion dynamics remain poorly understood, despite the exceptionally low thermal conductivities of t...

High-throughput Materials-to-Device Discovery of Lead-free Double Perovskites Beyond Radiative-limit Metrics

Abstract Metal halide perovskite solar cells (PSCs) are leading candidates for next-generation photovoltaics, yet their instability and lead toxicity motivate environmentally benign alternatives. Lead-free double perovskites offer improved structural robustness but often exhibit weak near-band-edge absorption and modes...

Chemical process modeling and numerical analysis of radiative Casson fluid flow through a porous medium with thermal diffusion and inclined magnetic field effects

Abstract This research investigates the flow behavior and heat transfer characteristics of Casson fluid through a porous medium, considering the combined effects of radiation, thermal transmission, inclination angle, and magnetic field. The study is conducted by analyzing the fluid motion over a bounding plate, which i...

SYNAPSE: Symmetric Neurograph Augmentation via Probabilistic Diffusion Learning for fMRI-Based ADHD Identification

Mathematical Formulation and Computational Implementation of a Fisher-KPP Model for Glioblastoma Invasion under Fractionated Radiotherapy

Glioblastoma (GBM) is a highly infiltrative primary brain tumor, and reaction-diffusion models are widely used to describe how its cells spread and proliferate. We derive the classical Fisher-KPP equation from mass conservation, Fickian diffusion, and logistic growth, and extend it to fractionated radiotherapy through...

Self-modulation of photoemission at the picosecond time scale

The pulse response of negative electron affinity GaAs photocathode over a wide range of quantum efficiencies has been measured. Low quantum efficiencies, where an intense excitation is needed, may lead to rapid dynamic change of the transport conditions on a time scale of a few picoseconds. This phenomenon is attribute...

A Numerical Simulation to Understand the Impact of Electrode Porosity on the Performance of Electrolyte Supported Planar Solid Oxide Fuel Cell Under Intermediate Temperature

There have been extensive research efforts toward understanding electrode porosity in solid oxide fuel cell (SOFC). Porosity can enhance gas diffusion and reactant transport, enabling better access to the catalytically active sites on the electrode surface. This can lead to improved cell performance and efficiency. The...
