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

Combined corrosion and fatigue performance of joined materials for automotive applications

, 2016
The aim of this study is to evaluate fatigue performance of joined assemblies (spot weld and/or adhesive bonding) in corrosive environment. Various assemblies have been tested in alternated and simultaneous fatigue-corrosion modes.

Locked in Transition: Examining the Role of Paradoxical Tensions in the Transition From Industrial Cluster to Eco‐Clusters

Business Strategy and the Environment, EarlyView.
ABSTRACT Industrial clusters are central to the circular economy transition, yet how they develop into eco‐clusters and the paradoxical tensions this transformation fuels remain underexplored. Drawing on 48 in‐depth interviews and secondary data from a Turkish textile‐recycling cluster, we develop an empirically grounded model of eco‐cluster transition

Practicing Strategic Financial Sustainability in Small Cultural Non‐Profits: Evidence From London Museums

Business Strategy and the Environment, EarlyView.
ABSTRACT Small cultural museums play an important role in sustaining local heritage, community identity and inclusive cultural participation, yet they face persistent financial and organisational constraints. This study examines how financial sustainability is achieved and maintained in three small cultural museums through a qualitative‐led mixed ...

Modeling for corrosion fatigue crack initiation life based on corrosion kinetics and equivalent initial flaw size theory

, 2018
In present paper, a novel, effective and economical model based on corrosion kinetics and equivalent initial flaw size theory was proposed to predict the corrosion fatigue crack initiation (CFCI) life of E690 steel in simulated seawater.
