Mechanisms of the Ammonium Sulfate Roasting of Spent Lithium‐Ion Batteries

open access: yesGlobal Challenges, Volume 6, Issue 12, December 2022., 2022
Thermogravimetric experiments are performed to analyze the mechanism of the sulfation conversion process. First, the reaction activation energies of sulfate‐assisted roasting are calculated using two different models. Then, nucleation and growth are determined and verified as the sulfation reaction model by the Šatava‐Šesták method.

Will Iron Forge the Future of Metal‐Air Batteries in Grid Scale Energy Storage?

open access: yesChemSusChem, EarlyView.
This Perspective paper highlights different aspects of iron‐air batteries, as an appealing sustainable alternative energy storage technology for grid‐scale applications. The utilization of iron as an anode is attractive, since it is abundant and safe to handle, recyclable and affordable, has multielectron reversible redox activity, holds historically ...

Microwave‐Assisted Rapid Hydrothermal Synthesis of Vanadium‐Based Cathode: Unravelling Charge Storage Mechanisms in Aqueous Zinc‐Ion Batteries

open access: yesChemSusChem, EarlyView.
A novel vanadium‐based cathode, KMnVOH, was synthesized via a microwave‐assisted method, achieving 260 mAh g−1 at 5 C with 94 % retention over 2000 cycles in aqueous Zn(CF₃SO₃)₂ electrolyte. Its stability stems from interlayer water, K, and Mn ions enhancing the layered structure. A dual proton/Zn ion charge storage mechanism involving ZHT formation is

Geoarchaeological characterisation of a Younger Dryas site in the Alpine uplands: Cornafessa rock shelter (Italy)

open access: yesGeoarchaeology, Volume 38, Issue 1, Page 35-56, January/February 2023., 2023
Abstract The effects of the Younger Dryas (YD) fluctuation on Late Pleistocene hunter‐gatherers' settlement and subsistence systems in the southern Alps are poorly known. This is primarily due to the scarcity of archaeological sites dating from the YD, in contrast with the extensive evidence available from the lateglacial interstadial and the early ...

Testing the fidelity of zircon as a provenance indicator in fluvial‐fan successions: An example from the Palaeogene Colton Formation, Central Utah, USA

open access: yesThe Depositional Record, EarlyView.
This study integrates and expands the U–Pb detrital zircon dataset from the Colton fluvial system to highlight spatial variations in provenance signals within the early Palaeogene infill of the south‐western Uinta Basin, in Utah. The provenance data sheds light on the origin of clastic sediment and on the relationship with potential palaeodrainage ...

Evidence for subsidence rate variation in the Newark Basin and its influence on the deposition of fluvial sediments of the Stockton Formation

open access: yesThe Depositional Record, EarlyView.
The Newark Basin has seen renewed interest recently as a potential location for carbon sequestration. This study uses a recently exposed outcrop to investigate the reasons behind varying lithologies and post‐depositional soft‐sediment deformation in the fluvial sandstones of the Stockton Formation. Using field observations and sediment geochemistry, we

Redox‐active ligands as a challenge for electronic structure methods

open access: yesJournal of Computational Chemistry, Volume 44, Issue 3, Page 468-479, January 30, 2023., 2023
The 3d transition metal complexes with redox‐active ligands are highly attractive for catalysis, but a challenge for first‐principles electronic structure methods such as density functional theory (DFT). The ligands’ redox‐activity can lead to the self‐consistent field algorithm converging to high‐energy solutions.
