Herein, ethacridine lactate (EAL) is employed as a multifunctional additive in the perovskite precursor solution to regulate film quality and interfacial properties. Owing to the presence of a carboxyl group in the lactate anion and two amino groups in the ethacridine cation, EAL interacts with undercoordinated Pb2+ and dangling I− species, which stabilizes the perovskite structure and promotes charge transport across the perovskite/carbon interface. Consequently, the EAL-modified films show improved morphology and reduced defect density, resulting in enhanced photovoltaic performance.

Graphite, the dominant commercial anode material, suffers from sluggish ion transport kinetics and interfacial instability, which pose significant challenges to the fast-charging performance of LIBs. Previous strategies, including surface coatings and conductive network construction, often address these challenges in isolation, leading to an inherent trade-off between structural stability and electrical conductivity. Here, we report a scalable one-step pyrolysis of pitch that concurrently constructs a conformal amorphous-carbon shell and an integrated graphene network on graphite. In this process, the molten pitch serves as a molecular binder that anchors graphene sheets onto graphite, forming continuous electron pathways, while subsequent carbonization yields a robust hard-carbon shell that reinforces the solid–electrolyte interphase. This dual-functional interface markedly enhances electrochemical performance, delivering a reversible capacity of 240 mAh·g−1 at 1C and retaining 333 mAh·g−1 after 500 cycles at 1C, significantly outperforming pristine graphite. Even under a demanding 3.0C regime, the modified anode maintains around 170 mAh·g−1 after 500 cycles with 94.4% retention.

Conventional detection methods are often limited by expensive instrumentation and complex procedures, whereas surface-enhanced Raman scattering (SERS) has emerged as a promising alternative due to its high sensitivity and operational simplicity. In this study, we developed an ultrasensitive SERS-based method for the Pb2+ detection using L-cysteine-functionalized bismuth nanoparticles as probes. L-cysteine binds Pb2+ through its −COOH and −NH2 groups, inducing nanoparticle aggregations and generating Raman hotspots that enhance the signal of 4-aminothiophenol (4-ATP). Additionally, an electrodeposited bismuth substrate further amplifies the SERS response.
