Metallicity, Atomic Disorder, and Li-Ion Storage in Fast-Charging Anodes Open
Oxides of Nb with Wadsley-Roth shear structures comprise a family of stable, high-rate anode materials for Li-ion batteries. A particular pair of them offers the unusual opportunity to test how important metallic conduction of the starting…
Chemical Origin of in Situ Carbon Dioxide Outgassing from a Cation-Disordered Rock Salt Cathode Open
In situ carbon dioxide (CO2) outgassing is a common phenomenon in lithium-ion batteries (LiBs), primarily due to parasitic side reactions at the cathode-electrolyte interface. However, little is known about the chemical origins of the in s…

Microcalorimetry electrothermal impedance spectroscopy (ETIS) informs entropy evolution at individual electrodes of PNb9O25 or TiNb2O7 battery cells Open
This study proposes a novel and fast microcalorimetry electrothermal impedance spectroscopy (ETIS) method based on heat generation rate measurements at each electrode of a lithium-ion battery cell. This new method is capable of retrieving …

Rapid and Reversible Lithium Insertion in the Wadsley–Roth-Derived Phase NaNb<sub>13</sub>O<sub>33</sub> Open
The development of new high-performing battery materials is critical for meeting the energy storage requirements of portable electronics and electrified transportation applications. Owing to their exceptionally high rate capabilities, high…
Doping molecular organic semiconductors by diffusion from the vapor phase Open
Spiro-OMeTAD can be doped by infiltration of F4TCNQ from the vapor phase without causing crystallization. Optical spectroscopy and thermopower measurements examined the question of the formation of dication states by charge transfer doping.
Composition, structure, and semiconducting properties of Mg<i> <sub>x</sub> </i>Zr<sub>2−<i>x</i> </sub>N<sub>2</sub> thin films Open
Synthesis and characterization of MgxZr2–xN2 (0.5 ≤ x ≤ 1.8) thin films deposited by reactive magnetron co-sputtering in nitrogen plasma is reported. Composition measurements show that nitrides with low oxygen content (less than 1%) can be…

Pyrene hydrogel for promoting direct bioelectrochemistry: ATP-independent electroenzymatic reduction of N<sub>2</sub> Open
We demonstrate a novel hydrogel material to facilitate direct bioelectrochemistry of a wide range of redox proteins and enable ATP-independent electroenzymatic reduction of N2 by nitrogenase.
