Article Abstract
Electrogenerated chemiluminescence (ECL) of Ru(bpy) was studied at a MoS nanosheets modified glassy carbon electrode (MoSNS/GCE) in neutral condition. Electrochemical results revealed that MoS nanosheets could significantly catalyze the electrochemical oxidation of Ru(bpy), as a result, strong anodic ECL was obtained. Several impact factors, such as the modified amount of MoS nanosheets suspension, the pH value, and the concentration of Ru(bpy), were investigated to obtain the optimal experimental condition. Dopamine exhibited apparent inhibiting effect on ECL intensity of Ru(bpy)-MoS nanosheets through energy transfer process, and could be sensitively detected in the range of 1.0 × 10 to 1.0 × 10 mol L. The linear equation between the decrease of ECL intensity and the logthium of dopamine concentration was determined as ΔI = 9965.02 + 1077.03lgC (C in mol L), with the detection of 8.5 × 10 mol L (3σ). The modified electrode exhibited satisfactory sensitivity, selectivity, and stability, which can be used to detect dopamine in real samples.

Understanding the behavior and fate of microplastics (MPs) in aquatic environment is crucial for assessing their potential risks. This study investigated the heteroaggregation behaviors of MPs with representative 2D nanosheets, MoS and graphene oxide (GO), under various conditions, focusing on the transport behavior of the resulting aggregates. It was found that the destabilization capabilities of 2D nanosheets are notably stronger than those of well-reported nanoparticles.

Article Synopsis
- During fast-charging, uneven lithium plating on graphite anodes leads to performance issues and safety risks for lithium-ion batteries due to the formation of a passivation layer known as the solid-electrolyte interphase (SEI).
- A molybdenum disulfide (MoS) coating on natural graphite modifies the SEI properties, resulting in faster charging times and improved long-term cycling performance by enhancing lithium transport and reducing interfacial resistance.
- The MoS-NG anode demonstrates superior fast-charging capabilities, achieving a charging time of 14.7 minutes at 80% state of charge, making it a viable option for electric vehicle applications over 300 cycles without sacrificing energy density.

Photocatalytic removal of antibiotic such as ciprofloxacin from polluted water is of great value for eco-environment protection. To further enhance the piezoelectric effect in photocatalysis, we designed and synthesized a ternary heterojunction piezoelectric photocatalyst through uniformly loading MoS nanosheets onto BiFeO (BFO) nanofibers, namely MoS/BiS/BFO. Piezoresponse force microscopy and Kelvin probe force microscopy demonstrated its enhanced piezoelectric properties, showing a maximum amplitude displacement of 395.
