Structure of the Multiphase Chalcolithic Tell Chiselet–Grădiștea Fundeanca (Romania) From SH‐Wave Full‐Waveform Inversion, Borehole Geophysics and Coring

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The emergence and development of settlement mounds, also called tells, is of major interest for the analysis of socio‐economic transformations occurring in the lower Danube plain during the East European Chalcolithic period. In this context, the multiphase chronology and structural layout of tells are highly relevant indicators, but small ...

Enhanced Photoelectrochemical Water Splitting Using Bismuth/Bismuth Selenide Nanocomposites

open access: yesChemistry – An Asian Journal, Volume 20, Issue 6, March 17, 2025.
Bismuth/Bismuth Selenide (Bi/Bi₂Se₃) nanocomposites exhibit enhanced photoelectrochemical (PEC) water splitting performance due to optimized energy band alignment and efficient charge separation. The figure illustrates the impact of synthesis temperature on bandgap tuning, leading to improved photocatalytic activity and hydrogen evolution.

“Dead Lithium” Formation and Mitigation Strategies in Anode‐Free Li‐Metal Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
Anode‐free lithium metal batteries, though promising due to their high energy density, face challenges from dead lithium formation. “Dead lithium”, disconnected from the anode, causes capacity loss, increased resistance, and safety risks. This review explores the origins of dead lithium, its impact on battery performance, and potential strategies for ...

Exploring quinolinone–chalcones: Synthesis, antioxidant potential and industrial applications in biofuels

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biofuels undergo oxidative degradation, which reduces their storage stability and efficiency, hindering their large‐scale adoption and integration into the global energy matrix. To address this issue, we synthesized and characterized four novel quinolinone–chalcone derivatives (substituted with Br, Cl, OCH3 and OCH2CH3) as potential ...

Creating a database of biobased hydrogen production: country‐based evaluations and comparative analysis

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Hydrogen is increasingly recognized as a crucial element in a sustainable future, providing a variety of solutions to address the climate crisis. Its importance is emphasized by its adaptability, high energy content, and capacity to decarbonize a number of industries, including steel production, the chemical sector (e.g., ammonia and methanol ...
