Surface Charge Modulation in Covalent Organic Frameworks for Controlled Pt‐Photodeposition and Enhanced Photocatalytic Hydrogen Evolution

open access: yesSmall, Volume 21, Issue 27, July 10, 2025.
This study demonstrates that the photocatalytic hydrogen evolution efficiency of COFs can be effectively controlled by modulating surface charge via post‐synthetic linkage conversion from imine to amide. This unique interfacial modification approach switches the surface charge of COFs and introduces a shift in the reaction mechanism of the in situ Pt ...

BioTIME 2.0: Expanding and Improving a Database of Biodiversity Time Series

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 5, May 2025.
ABSTRACT Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic ...

“Dark taxonomy”: A new protocol for overcoming the taxonomic impediments for dark taxa and broadening the taxon base for biodiversity assessment

open access: yesCladistics, Volume 41, Issue 2, Page 223-238, April 2025.
Abstract We are entering the sixth mass extinction with little data for “dark taxa”, although they comprise most species. Much of the neglect is due to the fact that conventional taxonomic methods struggle with handling thousands of specimens belonging to hundreds of species. We thus here propose a new strategy that we call “dark taxonomy”.

GIS‐based G × E modeling of maize hybrids through enviromic markers engineering

open access: yesNew Phytologist, Volume 245, Issue 1, Page 102-116, January 2025.
Summary Through enviromics, precision breeding leverages innovative geotechnologies to customize crop varieties to specific environments, potentially improving both crop yield and genetic selection gains. In Brazil's four southernmost states, data from 183 distinct geographic field trials (also accounting for 2017–2021) covered information on 164 ...

Unlocking renewable energy potential: A case study of solar and wind site selection in the Kasserine region, central‐western Tunisia

open access: yesEnergy Science &Engineering, Volume 12, Issue 3, Page 771-792, March 2024.
Abstract Developing wind and solar photovoltaics on a large scale requires substantial financial investments, making it crucial to identify the most suitable locations beforehand. To address this issue, a spatial analysis is carried out to determine the most potential sites for hosting large‐scale solar photovoltaic and wind systems in the region of ...
