Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Connectivity‐Dependent Mechanics of Main‐Chain Oligomers in Side‐Chain Liquid‐Crystalline Polyacrylate Networks

Journal of Polymer Science, EarlyView.
Main‐chain liquid‐crystalline oligomers are incorporated into side‐chain polyacrylate elastomers either as covalently connected strands or as non‐network‐bound, physically confined chains. Both architectures contribute to short‐time soft elasticity, but only the capped oligomer shows an additional long‐time terminal relaxation.

Effect of Hydroxyl‐Terminated Polybutadiene Grade on Rheology and Settling of High‐Solids Mixtures of Mock Propellants

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT The most common binder used in composite rocket propellants is based on the pre‐polymer hydroxyl‐terminated polybutadiene (HTPB). It has been shown to have excellent mechanical properties and a long life once crosslinked, and studies have examined the kinetics of crosslinking and pot life of energetic formulations with HTPB.

Biomimetic robots driven by smart materials: Motion forms, stimulation methods and applications

Responsive Materials, EarlyView.
Biomimetic robots enhance adaptability by mimicking biological systems, but rigid materials limit performance. Smart materials with stimuli responsiveness and shape adaptability enable more flexible actuation and improved environmental interaction.

Intelligent Continuum Micromachines in Complex Confined Spaces

SmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...
