Exploring future changes in land use and carbon storage (CS) under different climate scenarios is important for optimizing regional ecosystem service functions formulating sustainable socioeconomic development policies. We proposed a framework that integrates the system dynamics (SD) model, patch-generating simulation (PLUS) Integrated Valuation of Ecosystem Service Tradeoffs (InVEST) model to dynamically simulate use/cover change (LUCC) CS at city level based on SSP-RCP provided by CMIP6....

Abstract Selective molecular recognition is an important alternative to the energy-intensive industrial separation process. Porous coordination polymers (PCPs) offer designing platforms for gas because they possess precise controllability over structures at level. However, PCPs-based separations are dominantly achieved using strong adsorptive sites thermodynamic or pore-aperture control size sieving, which suffer from insufficient selectivity sluggish kinetics. Developing PCPs that work high...

The corresponding probabilities $1∕2$, $1∕8$, $2∕23$, etc.,...
