Electro‐Organic Synthesis at a Stable Oil/Water/Solid Three‐Phase Interface Reactor

Angewandte Chemie, EarlyView.
A porous membrane electrode (PME) reactor is developed to promote oil/water/solid three‐phase interfacial contact for electro‐organic synthesis. By promoting the formation of an oil/water interfacial region within or near an amphiphilic catalytic layer, the reactor enables efficient conversion of water‐insoluble organic reactants in aqueous ...

Influence of in situ biological activity on the vertical profile of pre-emergence herbicides in sediment [PDF]

, 2009
The in situ effect of biological activity on herbicide degradation was studied in sediment. Early diagenesis indicators of organic matter (OM) was selected to provide information on the presence and the kinetics of the various biotic and abiotic ...

Pre-emergent herbicide screening for wheat

Revista Caatinga
ABSTRACT Weed control is a challenge in crop management due to the limited number of registered herbicides, especially for preemergent application. This study aimed to investigate the selectivity of pre-emergent herbicides with different mechanisms of action for wheat.

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

American Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Improving access to new technologies: An experiment with Kenyan input sellers

American Journal of Agricultural Economics, EarlyView.
Abstract Agrodealers play a critical role in rural economies, selling essential inputs for agricultural production, stocking new products, and providing farmers with technical advice. However, uncertainty can discourage them from stocking newer, less familiar products, limiting the availability of innovative technologies and leading to market failures ...

Policy uncertainty shocks and farm investments in Europe: Evidence from a newspaper‐based index

American Journal of Agricultural Economics, EarlyView.
Abstract In order to quantify the impact of agricultural policy uncertainty on European farmers' investment behavior, we construct a newspaper‐based monthly index of European agricultural policy uncertainty from 2013 to 2023. We use 327,224 newspaper articles to assess and compare the trends in policy uncertainty across five top agricultural producers ...
