Characterization and Selection of Contractile Actuators for Soft Robotics Operating in the Quasistatic Regime

Advanced Intelligent Systems, EarlyView.
We developed methods to characterize soft contractile actuators using force–displacement measurements in the passive state and the total force in the active state and define the operational range of thermal, electrothermal, and pneumatic muscles. A graphical method enables the selection of an actuator based on the required mechanical force–displacement

Balancing Exploration and Exploitation Through a Sequential Hybrid of Roach Infestation and Mayfly Algorithms for Constrained Engineering Design Optimization

AI &Innovation, EarlyView.
ABSTRACT Maintaining an effective balance between exploration and exploitation is essential during optimization processes, from mathematical functions to more complex problems such as constrained engineering design optimization, particularly when addressing highly nonlinear issues with numerous local optima and strict feasibility requirements.

Navigating Whiteness in Australia's Anti‐Racism Movement: A Duoethnographic Inquiry by Women of Colour Scholars

Australian Journal of Social Issues, EarlyView.
ABSTRACT This paper applies Critical Race Theory (CRT) to explore how whiteness operates within Australia's anti‐racism movement as a structuring force that shapes discourse, practice and policy. Despite the anti‐racism movement offering crucial spaces for resistance and reform, it remains entangled in Australia's settler‐colonial present and systemic ...

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

Journal of Applied Polymer Science, EarlyView.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Changing a Winning Team—Replacement of Brominated Flame Retardant and Antimony Trioxide in Acrylonitrile–Butadiene–Styrene

Journal of Applied Polymer Science, EarlyView.
This comprehensive study investigates reducing the amount of brominated flame retardant (Br) and/or antimony trioxide (ATO) in acrylonitrile–butadiene–styrene. Therefore, condensed‐phase flame‐retardant mechanisms are introduced into the flame‐inhibition system.

Innovative Metal‐Modified Resins via 3D Printing of Triply Periodic Minimal Surface Structures

Journal of Applied Polymer Science, EarlyView.
A solvent‐free dual‐monomer strategy enables the direct 3D printing of nickel‐containing TPMS catalyst supports with uniform metal distribution and preserved open‐channel architecture. The resulting structures exhibit excellent printability, thermal and water stability, and enhanced flexibility, offering a promising platform for next‐generation ...

Influence of Slenderness Ratio on Buckling Behavior of Reinforced Concrete Columns: A Finite Element Analysis

Advances in Materials Science and Engineering
Reinforced concrete columns (RCCs) are critical load-bearing elements in structural systems, where stability is often governed by buckling, particularly in slender members subjected to axial compression.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.
