A Two‐Stage Optimization Approach for Selecting Electric‐Flight Airports

Networks, EarlyView.
ABSTRACT The decarbonization of short‐haul air transport has gained increasing attention, with electric aircraft emerging as a promising alternative to conventional short‐haul aviation. However, given the substantial investment anticipated for the necessary infrastructure, a strategic and globally coordinated selection of airports is imperative.

Mixture-Quantitative Structure-Property Relationship Approaches for Jet Fuel-Component Blends: A Review. [PDF]

Mol Inform
A literature review of QSPR approaches to predict jet fuel properties. It exposes the fundamental principles of QSPR and illustrates pure‐compound QSPR through examples of applications for jet fuel components. Mixture‐QSPR (M‐QSPR) modeling specificities are addressed: mixtures representation, design of descriptors for mixtures, and impact on internal ...

Improvement of water absorption behavior and mechanical properties of woven jute fiber‐reinforced epoxy composites with waste eggshell filler

Polymer International, EarlyView.
This study investigates the influence of waste eggshell powder on the water absorption and mechanical properties of jute fiber‐reinforced epoxy composites. Optimal eggshell filler content (2 wt%) significantly enhances composite performance by reducing water absorption and improving mechanical properties.

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...
