Multiobjective Environmental Cleanup with Autonomous Surface Vehicle Fleets Using Multitask Multiagent Deep Reinforcement Learning

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a multitask strategy for plastic cleanup with autonomous surface vehicles, combining exploration and cleaning phases. A two‐headed Deep Q‐Network shared by all agents is traineded via multiobjective reinforcement learning, producing a Pareto front of trade‐offs.

Synergistic Effects of Electricity and Light for Efficient Iron‐Catalyzed Recycling of Polystyrene Waste

open access: yesAngewandte Chemie International Edition, EarlyView.
The synergistic interplay of electricity, light and earth‐abundant, nontoxic iron catalysis allowed for the efficient recycling of post‐consumer polymers into value‐added products. This robust depolymerization strategy was viable on multigram‐scale, where the cathodic hydrogen evolution reaction presents an attractive opportunity for a green hydrogen ...
