Thermal Stability of Aliphatic and Semiaromatic Polyamides: Tailoring the Choice of Isothermal Aging Temperature by Using Kinetic Models of Degradation

Journal of Applied Polymer Science, EarlyView.
Thermogravimetric analysis was performed to study the degradation of aliphatic and semiaromatic polyamides intended for the electrical insulation of future electric aircraft. Using the TGA results, the Flynn and Wall method and Toop's model, the activation energies for the degradation processes were calculated, and kinetic models of the degradation ...

Design principles for vitrimers: Linking dynamic covalent chemistry, network architecture, and engineering performance

Bulletin of the Korean Chemical Society, EarlyView.
This review examines vitrimer performance from a broader perspective, considering not only dynamic covalent chemistry but also molecular structure, network architecture, and rheological behavior. These factors are discussed in relation to service and processing windows, reprocessing, repair, and engineering applications, providing a multiscale ...

Electrospinning of polyamide 6/modified-keratin blends

, 2007
: Protein material resulting from chemical free steam explosion of wool was mixed in different proportion with polyamide 6 in formic acid. The viscosity of the blend solutions decreases with the increase of the protein amount in the blend.

Micro‐ and nanoplastics in gastrointestinal disorders: Mapping the translational gap between exposure, biomonitoring, and pathogenic mechanisms

BMEMat, EarlyView.
This review highlights critical “translational gaps” in understanding micro‐ and nanoplastics impacts on gastrointestinal diseases, bridging exposure, detecting, and mechanistic toxicology. Abstract Micro‐ and nanoplastics (MNPs) have become pervasive environmental contaminants with increasing evidence linking them to adverse health outcomes.

Cluster Analysis of Circular Economy and Industrial Symbiosis Practices and Their Impact on Sustainability Performance in the Plastics Industry

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how plastics manufacturing firms can be classified according to their level of implementation of circular economy (CE) and industrial symbiosis (IS) practices and how such adoption influences sustainability performance. Using data from plastics manufacturing firms, we integrate cluster analysis with partial least squares ...

A facile method to improve thermal stability and flame retardancy of polyamide 6

, 2019
Despite great advances for flame-retardant polyamide 6 (PA6), there is still a lack of facile strategies for creating advanced flame-retardant PA6 composites without significantly compromising its thermal stability to date.

From Material Tensions to Organizational Paradoxes: How Manufacturers Cope With the Limits of Circular Product Design

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular product design (CPD) is central to advancing the circular economy by enabling the narrowing, slowing, and closing of resource flows. Yet, its implementation remains persistently challenging for firms. Prior research has largely framed these challenges as discrete barriers, overlooking the structural contradictions embedded in CPD ...

The Three Musketeers of Coevolutionary Circular Design

Business Strategy and the Environment, EarlyView.
ABSTRACT The transition from a linear to a circular economy necessitates systemic changes in product design, data sharing, and material flows. Applying a coevolutionary framework, this study shows how these three dimensions interact dynamically in circular economy transitions.
