Bio‐Based Epoxy Resins from Estragole: Achieving High Glass Transition Temperatures Comparable to DGEBA and Simultaneously Low Viscosities

Macromolecular Materials and Engineering, EarlyView.
Two novel bio‐based epoxy monomers, diglycidyl‐4‐allylphenol (DG‐4A) and triglycidyl‐diallylphenol (TG‐DA), derived from estragole (92% and 72% bio‐content), were synthesized and cured with isophorone diamin (IPDA) and 4,4´‐diaminodiphenyl sulfone (DDS). The resins show high Tgs, with DG‐4A reaching and TG‐DA exceeding DGEBA‐based systems. These resins

Robustness Assessment of Public Transport Networks in Various Graph Representations: Systematic Review, Decision Support, and Case Study

Networks, EarlyView.
ABSTRACT The analysis of certain properties of the underlying graph of a public transport network generates insights about the network's structure. Hereby, the choice of the graph representation depends on a trade‐off between complexity reduction and information preservation to adequately model a public transport network.

Correlation Between Strain Gradient and Fracture Damage Mechanism of TA18 Alloy Based on In Situ SEM/EBSD Analysis

Rare Metals, EarlyView.
ABSTRACT TA18 alloy is an ideal material for piping systems in the aerospace field, the low notch sensitivity and high damage tolerance enhance its engineering application value. However, the complex failure mechanism influenced by strain gradient necessitates further improvement of the service stability for TA18 alloy in practical engineering ...
