Molecular Modeling of the Microstructure Evolution during the Carbonization of PAN-Based Carbon Fibers [PDF]

arXiv, 2017
Development of high strength carbon fibers (CFs) requires an understanding of the relationship between the processing conditions, microstructure and resulting properties. We developed a molecular model that combines kinetic Monte Carlo (KMC) and molecular dynamics (MD) techniques to predict the microstructure evolution during the carbonization process ...

High voltage carbon-based cathodes for non-aqueous aluminium-ion batteries [PDF]

arXiv, 2020
Four different forms of carbon: activated carbon (AC) from human hair, AC from hemp fibers, a carbon fullerene extract consisting of C$_{60}$ and C$_{70}$ fullerene (CFEx) and Super-P carbon black were tested and compared as cathodes for non-aqueous aluminium-ion batteries (AIBs).

Rational Engineering of Nanostructured AgM (M = Au, Pt, Pd) Bimetallic Electrodes via Galvanic Replacement for Glycerol Electrolysis

Advanced Engineering Materials, EarlyView.
This study demonstrates the feasibility of fabricating free‐standing carbon paper electrodes by electroplating and galvanic replacement. Nanostructured AgM (M = Au, Pt, Pd) bimetallic catalysts are directly grown on the electrode substrate, which exhibit good performance for glycerol electrolysis, a sustainable approach for the co‐production of green ...

High-Performance Numerical Modeling of Nanofabrics with Distinct Element Method [PDF]

arXiv, 2019
A universal framework for modeling composites and fabrics of micro- and nanofibers, such as carbon nanotubes, carbon fibers and amyloid fibrils, is presented. Within this framework, fibers are represented with chains of rigid bodies, linked with elastic bonds. Elasticity of the bonds utilizes recently developed enhanced vector model formalism. The type

Multiple‐Repeated Plasma Surface Treatments for Significantly Improving Bonding Performance of Metal‐Carbon‐Fiber‐Reinforced Thermoplastic Polymer Dissimilar Adhesive Joints

Advanced Engineering Materials, EarlyView.
Multiple plasma surface treatments improved the Mode I fracture energy of metal‐carbon‐fiber‐reinforced thermoplastic polymer (CFRTP) joints by ≈240% compared to single treatments and nearly 2000% over untreated joints. This significant enhancement, achieved without modifying CFRTP surface roughness, is attributed to improved chemical bonding at the ...
