Abstract Dysprosium-doped Ruddlesden−Popper calcium manganates with compositions of Ca2-xDyxMnO4 are potential candidates for high temperature thermoelectric applications. The effect of dysprosium doping on the crystal structure of Ca2-xDyxMnO4 at room temperature and its thermal behavior between RT and 800 °C were investigated in the range 0

In this study, the electrospinning technique is shown to be a viable method for the synthesis of a bacteria-encapsulating bioanode. A coaxial set-up was designed to yield in one step a bioanode made of two fibers networks: one encapsulating the electroactive bacteria Shewanella oneidensis and the other one providing the necessary conductivity for electron transport throughout the bioelectrode. The electrical conductivity of this “integrated bioanode” (~ 10-2 to 10-3 S·cm-1) was deemed satisfacto...

Rechargeable aqueous aluminium batteries are the subject of growing interest, however, the charge storage mechanisms at manganese oxide-based cathodes remain poorly understood. In essense, every study proposes a different mechanism. Here, an in situ spectroelectrochemical methodology is used to unambiguously demonstrate that reversible proton-coupled MnO2 -to-Mn2+ conversion is the main charge storage mechanism occurring at MnO2 cathodes for a range of slightly acidic Al3+ -based aqueous electro...

ABSTRACT Electrospun carbon nanofibers (CNFs) are explored as a potential electrode material for bioanodes due to the advantages of a high specific surface area (surface area per volume), a good conductivity and an architecture and surface adapted to the electroactive bacteria colonization. These electrodes are colonized by exoelectrogenic strains – either the model bacterium Shewanella oneidensis or a wastewater-occurring bacterial consortium and are then integrated into a lab-scaled setup. Its...

We highlight 3D free-standing electrospun CNF electrodes as superior conductive scaffolds for the highly reversible proton-coupled MnIV(s) ↔ MnII(aq) conversion in a mild aqueous buffered electrolyte (pH 5). An electrochemical quartz crystal microbalance is used to in situ monitor these conversion reactions on the non-transparent CNF electrodes. Free-standing CNFs allow for a remarkably high relative MnO2 loading (63%, equivalent to an mMnO2/mCNF ratio of 1.7) at a maximal charge of 1.4 mA h cm−...

Contrary to molecular species, only very few solids are reported to host manganese (V) species. Herein, we report three new compounds with a hydroxyapatite structural backbone built on the MnVO43– ...

We report phase selective synthesis of intermetallic nickel silicide nanocrystals in inorganic molten salts. NiSi and Ni2Si nanocrystals are obtained by reacting a nickel (II) salt and sodium silicide Na4Si4 in the molten LiI-KI inorganic eutectic salt mixture. We report that nickel silicide nanocrystals are precursors to active electrocatalysts in the oxygen evolution reaction (OER) and may be low-cost alternatives to iridium-based electrocatalysts.
