Reconfiguring Fresh Produce Supply Chains in Response to Drought Risk: Evidence From the U.S. Broccoli Market

open access: yesAgribusiness, EarlyView.
ABSTRACT Drought is among the most severe and persistent threats to food supply chains, and relocating production to less drought‐prone regions offers a strategy to reduce this risk. This is particularly relevant for fresh vegetables, which are highly water‐intensive, yet drought‐driven reconfiguration strategies remain understudied.

Water‐Derived Radical Species Initiate Six‐Electron Oxidation of Cyclic Ketones in Microdroplets

open access: yesAngewandte Chemie, EarlyView.
Spontaneous six‐electron oxidation of cyclic ketones to yield dicarboxylic acids/keto acids is achieved in ethanol microdroplets containing about 2% water under ambient conditions without any metal salts, acids, or oxidants. Mechanistic studies show that trace amounts of water and molecular oxygen serve as active oxidants in this transformation ...

Challenges and enablers in fluidization technology

open access: yesAIChE Journal, EarlyView.
Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge

Selective Sequential Depolymerization of Mixed Plastics Mediated by Photothermal Conversion

open access: yesAngewandte Chemie, EarlyView.
This work provides a selective sequential depolymerization strategy for mixed plastic waste. The method enables depolymerization of poly(L‐lactide), polystyrene, and poly(ethylene terephthalate), including their post‐consumer plastics. Without presorting, monomer separation is achieved by leveraging the distinct chemical reactivities of each polymer in

Automated generative process synthesis via transformer‐based dual‐loop simulation and optimization

open access: yesAIChE Journal, EarlyView.
Abstract This study presents a novel framework for automated generative process synthesis, addressing the complexity of simultaneously optimizing discrete topologies and continuous operating variables. To overcome conventional superstructure limitations, we propose a dual‐loop architecture integrating generative transformers with rigorous process ...

Upcycling Water Pollutants Into Long‐Chain Polymers via Synergistic Interfacial Dechlorination and Organic Radical Stabilization

open access: yesAngewandte Chemie, EarlyView.
HEO‐regulated electronic structure drives nonradical PI activation, promoting ETP‐mediated polymerization of 4CP into high‐molecular‐weight products with enhanced surface enrichment. Concurrent dechlorination occurs via radical coupling and •OHads attack, enabling efficient carbon retention and selective product evolution at the liquid–solid interface.
