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.

Actuation Strategies for Underwater Jet‐Propelled Soft Robots

Journal of Field Robotics, EarlyView.
ABSTRACT This review article examines jet‐propulsion mechanisms in underwater soft robotic systems, focusing exclusively on physically fabricated and experimentally validated robots. Covering research published from 2013 to 2025, this study classifies and evaluates jet‐propulsion robots based on their actuation mechanisms.

Assessing Spatial Riverbed Clogging and Its Dynamics at the Reach Scale: A Coupled Approach Combining Field Measurements and 1D Hydro‐Sedimentary Numerical Modeling

River Research and Applications, EarlyView.
ABSTRACT Assessing spatial and temporal variability of clogging in gravel‐bed rivers is challenging because field methods typically rely on labor‐intensive measurements of fine‐sediment content, porosity, or hydraulic conductivity. Clogging is also highly dynamic, driven by hydro‐sedimentary conditions; yet few studies have examined it at large scales ...

Characteristic Study of a Valve-Matched Flow Single-Piston Miniature Water-Hydraulic Pump

IEEE Access
A miniature single-piston valve flow-matching water-hydraulic pump is described in this paper, which designs with a unique double-face cam mechanism to achieve the reciprocating motion of the piston and a new flow-matching valve to adapt to the ...

Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

Strategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

Considerations for the Design of Sinusoidal Slug Testing Methods

Groundwater, EarlyView.
Periodic hydraulic tests estimate aquifer properties using controlled groundwater‐level oscillations. Evaluating two sinusoidal slug‐test designs shows large motion errors when transfer‐link and flywheel ratios are high or variable. Rotating‐drive mechanisms are therefore suboptimal; stepper‐motor winches generate more accurate sinusoidal motion ...
