Influence of Hybrid Co‐wrapped Yarn Structure on the Energy Absorption and Crack Propagation Resistance of Fiber‐Reinforced Composites

Polymer Composites, EarlyView.
Helical wrapping of polyamide around E‐glass fibres deflects and bridges impact‐driven cracks, arresting damage that would otherwise propagate catastrophically in conventional side‐by‐side hybrid yarns. ABSTRACT Hybrid cowrapped (CW) yarns were engineered to enhance the impact resistance and damage tolerance of fiber‐reinforced composites.

Spent Artemisia arborescens as a Biowaste Filler for Melt‐Processed PBSA Biocomposites With Enhanced Disintegration and Aerobic Biodegradation

Polymer Composites, EarlyView.
Spent Artemisia arborescens biomass, recovered after essential‐oil steam distillation, was ground and melt‐compounded with PBSA (10 and 20 wt%), yielding biocomposites with accelerated biodegradation. ABSTRACT Artemisia arborescens is a Mediterranean shrub widely used for essential oil production, generating significant amounts of spent biomass after ...

Investigation of a Polyamide 6 (PA6) and Polybutylene Succinate (PBS) Blend as Candidate Matrix for Self‐Healing Application

Polymer Engineering &Science, EarlyView.
This illustration shows polyamide 6 (PA6) blended with 20–50% polybutylene succinate (PBS) by volume. The balance between tensile properties, fracture toughness and self‐healing capability is achieved in the 30% vol PBS blend. Thermal healing at 140°C results in 40% fracture toughness recovery in a blend containing 30% vol PBS.

2‐Amino‐3H‐phenoxazin‐3‐one is a lead inhibitor of Cuscuta campestris early development: structure–activity relationships of o‐aminophenol‐derived allelochemicals

Pest Management Science, EarlyView.
Phenoxazinones caused differential types of phytotoxic effects in C. campestris early development. APO is a coherent lead inhibiting C. campestris germination and early seedling growth. Abstract BACKGROUND 2‐Amino‐3H‐phenoxazin‐3‐one (synonym: questiomycin A; abbreviated as APO or Phx‐3) is a naturally occurring phenoxazinone‐type allelochemical with ...

Privacy‐Preserving Data‐Driven Distributed MPC for Heterogeneous Nonlinear Multi‐Agent Systems

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Distributed model predictive control (DMPC) is a cornerstone for coordinating multi‐agent systems, yet simultaneously ensuring data privacy, handling unknown nonlinear dynamics, and managing heterogeneous constraints remains an open challenge.

UAV‐Based Precision Seed Dropping for Automated Reforestation

Journal of Field Robotics, EarlyView.
ABSTRACT Wildfires and deforestation pose significant threats to forest ecosystems, motivating scalable methods for reforestation beyond labor‐intensive cultivation of native forest seedlings in nurseries. To enable large‐scale direct seeding of native species, this paper presents the design, analysis, and field evaluation of a UAV‐based seed‐dropping ...
