Exploring biofiber properties and their influence on biocomposite tensile properties

open access: yesPolymer International, EarlyView.
The study measured the physical, flow and chemical properties of 10 biofibers. It characterized the tensile properties of derived biocomposites and linked them using regression models, showing robust predictive performance. Abstract Biofibers serve as effective reinforcements for neat polylactic acid (PLA) in biocomposites, offering an attractive ...

On the radiation from unbaffled pistons and their dipole equivalent [PDF]

open access: yesarXiv
The radiation efficiency from simple vibrating planar surfaces is often used as a basis to describe the sound radiation from more complex structures, having important applications in various fields of acoustics. The low-frequency radiation efficiency of a baffled piston can easily be represented by a simple monopole source.

Low Tg PLA‐Based Copolymer Foams for Tissue Engineering Applications: Influence of Supercritical CO2 and N2 Mixtures on Open‐Cell Content, Morphology, and Storage Stability

open access: yesJournal of Polymer Science, EarlyView.
ABSTRACT Polylactid‐based (PLA) copolymer foams show a high potential for tissue engineering applications. However, tailored foam properties are required for these applications. As medical authorization is challenging for foams containing chemical modifiers or nucleating agents, tailored foam properties must be achieved by varying process parameters ...

A four-cylinder Stirling engine controls model [PDF]

open access: yes
A four working space, double acting piston, Stirling engine simulation was developed for controls studies. Two simulations, one for detailed fluid behavior, and a second model with simple fluid behavior but containing the four working space aspects and ...

Identifying key parameters for reliable assessment of entomopathogenic nematodes viability as affected by spray application stress‐related factors

open access: yesPest Management Science, EarlyView.
Commercial entomopathogenic nematodes (EPNs) were exposed to stress simulating spray application conditions, for viability assessment using different methods. Temperature impacted non‐lethal stress earlier than survival and activity, emphasizing the importance of measuring these parameters to assess pesticide application equipment (PAE) impact on EPN ...
