Polymer viscoelasticity from an orientational closure with implicit stretch

We propose a deviatoric-stress constitutive equation derived from orientational kinetics, while implicitly retaining contributions from conformational stretch. Starting from the dumbbell model, we show that conformational stretch affects orientational dynamics through an effective stress scale and rotational diffusivit...

Decision-aware multi-objective discovery of Cu2O-based photovoltaic materials integrating supply risk, stability, and bandgap engineering

The development of photovoltaic materials that simultaneously satisfy performance requirements and practical constraints is essential for large-scale energy applications. In this study, we propose a decision-aware, multi-objective screening framework for Cu2O-based materials targeting top-cell applications in Si-based...
