Rheological Characterization of a Low‐Concentration Water‐Based Collagen Dispersion Under Extensional, Shear, and Oscillatory Deformation

Polymer Engineering &Science, EarlyView.
Combined capillary and oscillatory rheology provided complementary insights into the linear, nonlinear, and extensional flow behavior of a 3 wt% collagen dispersion, improving the understanding of its processing‐relevant rheological characteristics. ABSTRACT This study presents an investigation of the extensional, shear, and oscillatory rheological ...

Exploring biofiber properties and their influence on biocomposite tensile properties

Polymer 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 ...

Aggregation‐induced enhanced emission for quantification of recycled content in automotive plastics

Polymer International, EarlyView.
Quantifying recycled content in four automotive plastics using aggregation‐induced enhanced emission showed that performance was highly dependent on both polymer and additive chemistries. Abstract The use of plastics in the automotive industry is increasing due to their versatility, light weight and affordability.

Droplet size spectrum, velocity, angle and flow rate of pulse‐width‐modulated spray nozzles with adjuvants

Pest Management Science, EarlyView.
Optimizing PWM performance requires not only appropriate duty cycle selection, but also careful choice of adjuvant formulation tailored to each nozzle type. Drift control agents increased droplet size and reduced fine droplets, mitigating PWM‐induced variability. Decreasing the duty cycle consistently narrowed the spray angle.

Circulant Matrix‐Based Box–Behnken Designs With Economic Run Sizes

Quality and Reliability Engineering International, EarlyView.
ABSTRACT We introduce Circulant Matrix‐Based Box–Behnken Designs (CBBDs), a new class of three‐level, second‐order response surface designs constructed using circulant matrix structures. These designs satisfy an enhanced orthogonal minimally aliased (OMA∗${\rm OMA}^*$) property: they retain the classical OMA property—where main effects are orthogonal ...

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full
