Quantifying translational and bond-orientational order metrics in hyperuniform and nonhyperuniform many-particle systems

This paper introduces a bond-orientational order metric τO\tau_O to complement the translational order metric τT\tau_T, demonstrating through analysis of hard-particle, random sequential addition, and stealthy hyperuniform systems that while bond-orientational order is generally subdominant to translational order, the two metrics are positively correlated and reveal distinct, preparation-dependent structural trajectories.

Overcoming Transport Layer Bottlenecks to Quantify Ionic Parameters from Transient Ion Current Measurements of Perovskite Solar Cells

This paper identifies the capacitance of transport layers as the fundamental bottleneck causing transient ion current (BACE) measurements in perovskite solar cells to overestimate ion density, and proposes correction methods based on ionic displacement and transport layer thickness extrapolation to accurately quantify ionic parameters.

A Reactive Molecular Dynamics Study on the Mechanical Properties of a Recently Synthesized Amorphous Carbon Monolayer Converted into a Nanotube/Nanoscroll

This study utilizes reactive molecular dynamics simulations to demonstrate that while amorphous carbon nanotubes and nanoscrolls exhibit lower critical fracture strains than their crystalline counterparts, their similar melting points and mechanical behaviors indicate that structural disorder overrides the topological differences that typically distinguish pristine nanotubes from nanoscrolls.

Self-Folding and Self-Scrolling Mechanisms of Edge-Deformed Graphene Sheets: A Molecular Dynamics Study

This molecular dynamics study reveals that the self-folding and self-scrolling behaviors of edge-deformed graphene sheets into graphene-based nanofolds or nanoscrolls are critically determined by the initial edge twist angles and temperature, with specific configurations leading to single-folded, multi-folded, or dual-state morphologies.

Dynamics and Structural Transformations of Carbon Onion-Like under High-Velocity Impacts

Using fully atomistic reactive molecular dynamics simulations, this study reveals that carbon nano-onions undergo distinct structural transformations upon high-velocity impact against a rigid substrate, transitioning from quasi-elastic deformation to diamondoid-like core formation via sp2sp^2-to-sp3sp^3 conversion, and finally to fragmentation into linear carbon chains as impact velocity increases from 2 to 7 km/s.

On the Thermomechanical Properties and Fracture Patterns of the Novel Nonbenzenoid Carbon Allotrope (Biphenylene Network): A Reactive Molecular Dynamics Study

This study employs reactive molecular dynamics simulations to reveal that the novel biphenylene network (BPN) exhibits exceptional thermomechanical properties comparable to graphene, including a Young's modulus of ~1019.4 GPa and a melting point of ~4024 K, while demonstrating a unique, direction-dependent inelastic fracture process involving four distinct morphological transitions that are suppressed by the presence of nanocracks.
