Energy Science &Engineering, EarlyView.This study demonstrates a two‐stage catalytic bioreactor system that converts real food waste into high‐purity biohydrogen and biohythane. In Stage‐1, an enriched Clostridium thermocellum culture combined with Ni2+─Fe2+ bimetallic catalysis enhances hydrolysis efficiency and hydrogenase activity, resulting in a 77% increase in H2 yield and 75.8% purity

Irrigation and Drainage, EarlyView.ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

Land Degradation &Development, EarlyView.ABSTRACT Soil is crucial for human survival but is threatened by erosion and contamination. Farmers play a pivotal role in soil conservation, thus, understanding what influences their decisions is crucial. The IN‐GEST SOIL project aimed to mitigate soil erosion and improve soil and vine quality in Piedmont vineyards, NW Italy.
