Summary: The efficiency of microbial fuel cells (MFCs) relies on the charge transfer capability from microbes to anodes, with redox mediators playing a crucial role. This study looked at the influence of 2-methyl-1,4-naphthoquinone (menadione (MD)) on yeast cells and found that baker's yeast cells were more resistant to dissolved MD. The maximal calculated power output of a designed baker's yeast-based MFC cell anode was 0.408 mW/m(2) at 24 mV.

Summary: Yeast supported iron nanoparticles (nZVI@SCM) synthesized by tobacco leaf extract were used in the heterogeneous Fenton-like degradation of methylene blue (MB). The composite showed high catalytic activity and could achieve 99.7% removal of 50 mg/L MB within 10 hours. The main reactive oxidizing species responsible for MB degradation were identified to be hydroxyl radicals in the bulk solution. The developed nZVI@SCM catalyst strategy provides a new route for enhancing the Fenton-like degradation of organic contaminants with less consumption of catalyst and oxidant.

Summary: Secondary zinc-air batteries (ZABs) show potential as sustainable energy storage, but their current capability is unsatisfactory. The limitations are mainly due to the air electrodes, hindering practical applications and commercialization. This study explores the use of metallic nickel as a conductive additive in the air electrodes, compared to carbon nanotubes (CNT), and demonstrates that the density and interaction of the additive with the active material are crucial for achieving long cycle life. The use of Ni as a conductive agent significantly increased the cycle life of secondary ZABs, delivering more than 2,400 cycles compared to only 88 cycles for carbon-based batteries.

Summary: The capacity degradation mechanism of an all iron aqueous redox flow battery (ARFB) was analyzed using iron and 2,2-bis (hydroxymethyl)-2,2',2''-nitrilotriethanol (Fe(BIS-TRIS)) complex as the redox active material for the anolyte. It was found that capacity degradation occurs due to the contact of Fe(BIS-TRIS) with oxygen in air, as confirmed by spectroscopic and electrochemical methods. The self-discharge of Fe(BIS-TRIS) exposed to oxygen during the anolyte step promotes the decay of battery performance.

Summary: This study predicts the redox potential differences of different functional groups of ferrocene derivatives using density functional theory and verifies the predictions through electrochemical evaluations. The results show that ferrocene derivatives with electron-donating groups have higher LUMO and HOMO energies compared to those with electron-withdrawing groups. Additionally, the redox potential of the ferrocene derivatives is linearly related to the onset potential of glucose oxidation reaction. Using ferrocene derivatives with electron-donating groups can significantly improve the maximum power density of enzymatic biofuel cells.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
