Biochar‐Based Fertilizer Is Cost‐Effective, Reduces Nutrient Input and Improves Nutrient Use Efficiency Without Decreasing Yield

open access: yesGCB Bioenergy, Volume 18, Issue 2, February 2026.
Co‐applying half‐rate BMC layer: (i) Reduced nutrient inputs and (ii) produced similar yield. ABSTRACT Developing high‐efficiency fertilizers with less environmental footprint is essential for sustainable cropping systems. This study evaluated a biochar mineral complex (BMC) to reduce nutrient leaching and increase nutrient use efficiency (NUE), yield,

Reflections for Biodiversity Researchers Engaging With Policy‐Science Interfaces

open access: yesThe Bulletin of the Ecological Society of America, Volume 107, Issue 1, January 2026.
Abstract Researchers who wish to engage in policy processes to help address the biodiversity crisis are often hindered by fear of the potential drawbacks to doing so. The complexity of political systems, the necessity to interact with policymakers or politicians outside of the work environment, the potential professional risks that may arise from ...

Hot Air Engines

open access: yesJournal of Applied Fluid Mechanics, 2011
Invented in 1816, the hot-air engines have known significant commercial success in the nineteenth century, before falling into disuse. Nowadays they enjoy a renewed interest for some specific applications. The "hot-air engines" family is made up of two
