Electrical and Thermal Conductivity of Polylactic Acid (PLA)-Based Biocomposites by Incorporation of Nano-Graphite Fabricated with Fused Deposition Modeling (open access)

Electrical and Thermal Conductivity of Polylactic Acid (PLA)-Based Biocomposites by Incorporation of Nano-Graphite Fabricated with Fused Deposition Modeling

This article describes a study to improve the electrical and thermal conductivity of the polylactic acid/wood flour/thermoplastic polyurethane composites by Fused Deposition Modeling (FDM). The results showed that, when the addition amount of nano-graphite reached 25 pbw, the volume resistivity of the composites decreased to 10⁸ Ω·m, which was a significant reduction, indicating that the conductive network was already formed. It also had good thermal conductivity, mechanical properties, and thermal stability.

Mechanical property enhancement of self-bonded natural fiber material via controlling cell wall plasticity and structure (open access)

Mechanical property enhancement of self-bonded natural fiber material via controlling cell wall plasticity and structure

This article explores self-bonded natural fiber material (SNFM) as a promising alternative for plastic and wood owing to its abundant raw material resources and low environmental impact. In this study, a high-performance SNFM was developed by the comprehensive treatments for the plasticity and structure of fiber cell walls. The self-bonded mechanism for natural fiber materials was also discussed. The SNFM products showed excellent mechanical performance, which was superior to that of natural wood and plastic.

Physical and optical properties of the International Simple Glass (open access)

Physical and optical properties of the International Simple Glass

This article presents physical property data (both published and previously unpublished) on a single batch of International Simple Glass (ISG), which was cast into individual ingots that were distributed to the collaborators. Properties from the atomic scale to the macroscale, including composition and elemental impurities, phase purity, density, thermal properties, mechanical properties, optical and vibrational properties, and the results of molecular dynamics simulations are presented, as well as information on the surface composition and morphology after polishing. Although the existing literature on the alteration of ISG is not extensively reviewed here, the results of well-controlled static alteration experiments are presented here as a point of reference for other performance investigations.

Influence of ordered L1₂ precipitation on strain-rate dependent mechanical behavior in a eutectic high entropy alloy (open access)

Influence of ordered L1₂ precipitation on strain-rate dependent mechanical behavior in a eutectic high entropy alloy

This article focuses on Al0.7CoCrFeNi, a lamellar dual-phase (fcc + B2) precipitation-strengthenable eutectic high entropy alloy. The back-stresses from the coherent L12 precipitate were insufficient to cause improvement in twin nucleation, owing to elevated twinning stress under quasi-static testing. However, under dynamic testing high density of twins were observed.
