Hydrogen fuel production from sugarcane and its byproducts – a critical review

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 1, Page 352-376, January/February 2026.
Abstract The transition to a low‐carbon economy has intensified the search for sustainable hydrogen (H2) production routes. Sugarcane and its byproducts, such as bagasse, molasses and vinasse, have emerged as promising feedstocks due to their ready availability and renewable nature. However, comprehensive evaluations of the efficiency, limitations, and

Fluvial deposits of the Ahr river (western Germany) reveal recurring high‐magnitude flood events over the last 1,500 years

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 1, January 2026.
Floods are one of the most critical environmental threats in Central Europe. We show the importance of geomorphological records from Ahr flood deposits for reconstructing past high‐magnitude flood events. Our chemolithostratigraphical analysis shows that centennial to millennial scale high‐energy flooding is not the exception but the rule in the Ahr ...

Global Copper Deposit Dataset: A New Open‐Source Database for Advanced Data Analysis and Exploration Targeting

open access: yesGeoscience Data Journal, Volume 13, Issue 1, January 2026.
We build a new, open‐source global copper deposit dataset (GCDD), facilitating AI‐driven data analysis for exploration targeting and improving our understanding of copper mineralizing systems and their mappable expressions. The GCDD hosts information about 1483 copper deposits worldwide, capturing key deposit attributes such as location, genetic type ...
