Probing the Compositional and Structural Effects on the Electrochemical Performance of Na(Mn‐Fe‐Ni)O2 Cathodes in Sodium‐Ion Batteries

open access: yesBattery Energy, EarlyView.
Mn‐Fe‐Ni layered oxides for Na‐ion cathodes with optimized transition metal ratios yielding superior capacity, cyclability, and biphasic structural characteristics. ABSTRACT This study systematically investigates an Mn‐Fe‐Ni pseudo‐ternary system for Na(Mn‐Fe‐Ni)O2 cathodes, focusing on the effects of varying transition metal fractions on structural ...

No evidence that seaweed cover enhances the deterioration of natural cement‐based mortar in intertidal environments

open access: yesEarth Surface Processes and Landforms, Volume 47, Issue 15, Page 3453-3464, December 2022., 2022
We evaluate the biogeomorphological impacts of seaweed on materials commonly used in maritime built heritage restoration. After 6 months of exposure to intertidal conditions, we found no evidence of enhanced deterioration of mortar prepared using natural cement when covered with seaweed compared to uncovered mortar.

Evaluating the breadmaking potential of wholemeal flours from einkorn, emmer, and spelt grown in the Canadian prairies

open access: yesCereal Chemistry, EarlyView.
Abstract Background and Objectives Ancient grains like einkorn, emmer, and spelt remain underutilized and underexplored, limiting their market potential. This study evaluates the chemical composition, rheology, pasting, and baking properties of spring growth habit einkorn, emmer, and spelt cultivars grown in the Canadian prairies compared to wholemeal ...

Topographic thresholds for gully head formation in badlands

open access: yesEarth Surface Processes and Landforms, Volume 47, Issue 15, Page 3558-3587, December 2022., 2022
Gully topographic threshold model was extended to badlands, on the basis of data collected in the Mediterranean environment in Italy and Spain, characterized by diversified climatic, lithological, geological and anthropogenic settings. Criteria for the attribution of curve number values has been more objectively defined in order to reduce arbitrariness

Transition‐Metal Dependence of Anion Redox Reversibility in Amorphous Electrodes

open access: yesChemElectroChem, EarlyView.
One major problem in anion redox, which is expected to contribute to the higher capacity of energy storage batteries, is the low reversibility owing to the phase separation of the anion component. The validity of transition‐metal selection guidelines for reversible anion redox reactions has been demonstrated, even for amorphous materials with ...

Aeolization on the Atlantic coast of Galicia (NW Spain) from the end of the last glacial period to the present day: Chronology, origin and evolution of coastal dunes linked to sea‐level oscillations

open access: yesEarth Surface Processes and Landforms, Volume 48, Issue 1, Page 198-214, January 2023., 2023
The Atlantic coast of NW Spain, where shingle beaches appear today, has suffered an important mobilization of dunes from a sea level about −120 m (bpsl), 20 ky ago. This aeolization caused the collapse of coastal/fluvial ecosystems (as forests) until the Late Holocene.

Synthesis of MgCl+ and Mg2+ Cation Based Novel Electrolytes: Impact of Polydentate Ethers

open access: yesChemElectroChem, EarlyView.
In this study, we explored the effects of stoichiometric amounts of DME and DG molecules on precursors A, and B, which were initially stabilized by THF molecules. The reaction of THF‐stabilized precursor A with DME or DG led to the formation of new THF‐soluble electrolytes: [DME•MgCl•3THF]+[Ph4Al]− (1) and [DG•MgCl.2THF]+[Ph4Al]− (2).
