Summary: The electrochemical behavior of gallic acid on a single-walled carbon nanotubes-modified electrode was investigated using cyclic voltammetry and chronoamperometry. Diffusion phenomena were found to be responsible for the overall current signal, and these phenomena were divided into four processes occurring in thin-layer or solution. The effects of scan rate, gallic acid concentration, and layer thickness on the voltammetric signal were discussed based on the diffusion processes in the thin-layer.

Summary: This study characterized the stability of new membrane-electrode assemblies of a proton-exchange membrane fuel cell under conditions of electrochemical aging. The effect of microstructure on the evolution of the electrochemical characteristics was investigated using various techniques. The introduction of carbon nanotubes as structural-modifying additives in highly porous electrodes showed differences in degradation compared to traditional electrodes, including lesser increase in Pt nanoparticle size and a more intense washout of Nafion. Mechanisms of the evolution of structurally modified electrodes under electrochemical aging were proposed.

Summary: This study demonstrates a new multifunctional additive, 2D poly(triazine imide) (PTI), for composite proton exchange membranes (PEMs), which significantly improves proton conductivity and current/power densities in industrially relevant PEM fuel cells (PEMFCs). The enhanced performance is attributed to the formation of polymer aggregate-PTI clusters with increased 2D character and improved long-range connectivity, as well as acid-base interactions with pyridinic nitrogen facilitating proton hopping mechanism at all relative humidities. This work offers a new membrane concept with proven benefits for important electrochemical technologies and provides design principles for future optimization of proton transport and water management within PEMs.

Summary: In this study, MoSe2 nanoflowers (NFs) were utilized as piezoelectric nanozymes for the dual-driven catalytic eradication of multi-drug-resistant bacterial biofilms. The piezoelectricity of MoSe2 NFs, combined with their enzyme-mimic activity, led to a significant increase in oxidative stress in the biofilms under ultrasound irradiation, resulting in a 4.0 log10 reduction of bacterial cells. In vivo studies showed that the MoSe2 NFs effectively reduced the burden of methicillin-resistant Staphylococcus aureus in mice under ultrasound control. Additionally, the surface coating of antioxidant poly(ethyleneimine) minimized off-target damage and promoted wound healing.

Summary: Single-atom catalysts with adjacent Fe nanoclusters supported on nitrogen-doped carbon aerogels show enhanced oxygen reduction reaction activity and anti-oxidation stability, resulting from increased 3d electron density and decreased magnetic moment of Fe atomic centers. A flexible zinc-air battery using these catalysts achieves remarkable performance, even at -40 degrees C, with high open circuit voltage, power density, and excellent durability after 2300 continuous cycles. These results highlight the significance of electronic manipulation in enhancing the durability of single atom catalysts.

Summary: Development of heterojunction is an effective strategy to enhance the hydrogen production performance of photocatalysts. In this study, a 2D/2D Z-scheme heterojunction-coupled Zn0.4Cd0.6S with g-C3N4 was fabricated using in situ hydrothermal approach. The sheet-on-sheet architecture allowed full contact of heterojunction, facilitating interfacial charge transfer and increasing surface-active sites. Moreover, the Zn-N coordination bond provided a strong interfacial interaction and spatially separated photogenerated charges along the Z-scheme mechanism. The optimal photocatalyst exhibited high hydrogen production rates (7.69 mmol g-1 h-1) under visible-light irradiation without any cocatalysts, four times higher than the g-C3N4 photocatalyst with Pt as a cocatalyst. The catalyst also showed long-term stability of up to 50 hours. Thus, a direct Z-scheme heterojunction with intimate contact and a well-definite bridging chemical bond holds promise for hydrogen generation.

Friedel-Crafts alkylation was then used to create multiple phenolic hydroxyl modified hyper-cross-linked polymers. The final polymers exhibited high surface area, large pore volume, and abundant phenolic hydroxyls. These results provide valuable insights into the synthesis and application of chemically modified polymers for enhanced adsorption performance.
