Constructing Electron/Ion Conductive‐Enhanced Ultrahigh Loading LiFePO4 Electrodes Using Polytetrafluoroethylene and Carbon Nanotubes for High‐Performance Batteries

Advanced Energy & Sustainability Research
Thick electrodes represent an effective approach for augmenting energy density of batteries. However, their increased thickness invariably leads to longer electron and ion transport distance, limiting the utilization of active material and hindering ...

Light-directed biofilm formation reveals the functional contributions of periplasmic cytochromes to the electrochemical activity of Shewanella oneidensis

mBio
Shewanella oneidensis MR-1 is a model electroactive bacterium whose extracellular electron transfer (EET) pathway includes a sequential network of c-type cytochromes that span the inner membrane, periplasm, and outer membrane.

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

Advanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Iron-respiring bacteria mediate regulatory mechanisms and pathways of electron donors and acceptors in carbon and nitrogen cycles

Applied and Environmental Microbiology
Iron-respiring bacteria play important roles in global material cycles owing to their electron transfer capabilities, yet their electron-transfer connections to carbon and nitrogen cycles in complex environments remain unclear.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

Advanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Creating high, portable proton polarization with photo-excited triplet DNP

Journal of Magnetic Resonance Open
Dynamic nuclear polarization (DNP) is a powerful tool to polarize nuclear spins and enhance the intensity of their magnetic resonance signal. For DNP a sample is doped with an agent providing unpaired electron spins. Then the sample is cooled in a strong

Electron beam guiding by a laser Bessel beam

Physical Review Accelerators and Beams, 2020
We investigate the dynamics of electrons counterpropagating along a radially polarized optical Bessel beam (OBB). (i) It is shown that a significant fraction of the electrons can be transversally trapped by the OBB even in the case of “unmatched ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
