Techno‐Economic Analysis of Polylactic Acid from Corn Stover: Understanding Uncertainty and Variability via Artificial Intelligence Tools

open access: yesAdvanced Sustainable Systems, EarlyView.
This study analyses the uncertainty and variability existing in the economic performance of polylactic acid (PLA) production, via integrating techno‐economic analysis with process models and Monte Carlo simulation enabled by artificial intelligence. The results show that the minimum selling price varies from $2,107 to $3076/t PLA.

Multifunctional Thermoplastic Paper Enabled by Plant‐Cell‐Derived Additives: A Paradigm of Paper‐Based “Modern Alchemy”

open access: yesAdvanced Science, EarlyView.
Building upon the concepts of papermaking wet‐end chemistry and chemical additives, this work upgrades conventional cellulosic paper into thermoplastic material using plant‐cell‐derived additives, synthesized via ring‐opening modification of pulp fibers and further disassembly into aqueous solutions as additives.

Global Evidence of the Unimodal Response of Ecosystem Respiration to Soil Moisture

open access: yesAdvanced Science, EarlyView.
Using global eddy covariance observations and a field experiment, this paper provides compelling evidence for the widespread unimodal relationship between soil moisture and ecosystem respiration and its water adaptation. Such knowledge facilitates understanding of soil moisture in affecting respiratory carbon emissions and has the potential to improve ...
