Synthesis of a National Soil Dataset Across Productive Land in Mexico: The Importance of Making Existing Data Accessible

open access: yesEuropean Journal of Soil Science, Volume 76, Issue 3, May–June 2025.
ABSTRACT The lack of soil data is a complication that most soil scientists will encounter throughout their career; this critical aspect is exacerbated due to the excessive cost of soil surveying. Consequently, it is essential to develop strategies that guarantee the permanent accessibility of past soil sampling efforts.

The potential of arbuscular mycorrhizal fungi to improve soil organic carbon in agricultural ecosystems: A meta‐analytical approach

open access: yesFunctional Ecology, Volume 39, Issue 4, Page 1016-1030, April 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Increasing soil organic carbon (SOC) in agroecosystems is a key objective for enhancing agricultural sustainability and mitigating climate change. Arbuscular mycorrhizal fungi (AMF) can increase yield and provide several other ecosystem services.

Electrocatalytic HER Performance of [FeFe]‐Hydrogenase Mimics Bearing M‐salen Moieties (M=Zn, Ni, Fe, Mn)

open access: yesChemistry – A European Journal, Volume 31, Issue 11, February 20, 2025.
The synthesis of novel complexes (5‐8) combining [(μ‐adt)Fe2(CO)6] fragments and M‐salen (M=Zn, Ni, Fe, Mn) complexes has been achieved. Computational studies confirm distinct geometries for the Zn, Ni, Fe, and Mn complexes. Electrochemical and electrocatalytic experiments reveal cooperative proton reduction and notable reductions in overpotential ...

Tree Diversity Increases Carbon Stocks and Fluxes Above—But Not Belowground in a Tropical Forest Experiment

open access: yesGlobal Change Biology, Volume 31, Issue 2, February 2025.
We examined the potential of mixed‐species planted forests compared to monospecific forests to act as a nature‐based solution to climate change mitigation through carbon sequestration. By analysing multiple carbon stocks and fluxes over 16 years in the world's oldest tropical tree diversity experiment, we found that planted forests with five tree ...

Space‐ and Time‐resolved Emission Features of Micro‐ and Nano‐sized Perylene‐based Zr Metal‐Organic Frameworks

open access: yesAdvanced Optical Materials, Volume 13, Issue 2, January 14, 2025.
The synthesis, structural characterization, and optoelectronic properties of a novel perylene‐based Zr metal‐organic framework (MOF) is reported here. Interestingly, a detailed study on the emissive features of micro‐ and nano‐sized crystalline samples of such material showed a strong dependence of the fluorescence, both in terms of its intensity and ...
