Summary: Constructing high-performance enzyme-free biosensors for glucose detection is crucial for early diagnosis of diabetes. In this study, copper oxide nanoparticles (CuO@Cu2O NPs) were immobilized in porous nitrogen-doped reduced graphene oxide (PNrGO) to create a CuO@Cu2O/PNrGO/GCE hybrid electrode for sensitive glucose detection. The hybrid electrode demonstrated excellent glucose sensing performance, surpassing that of the pristine CuO@Cu2O electrode, due to the synergistic effects between the numerous high activation sites of CuO@Cu2O NPs and the unique properties of PNrGO, such as excellent conductivity and large surface area with accessible pores. The enzyme-free glucose biosensor exhibited a significant glucose sensitivity of 2,906.07 mA mM(-1) cm (-2), an ultralow limit of detection of 0.13 mM, and a wide linear detection range of 3 mu M-6.772 mM. Additionally, the glucose detection method displayed outstanding reproducibility, favorable long-term stability, and excellent selectivity. Importantly, this study provides promising results for the continuous improvement of non-enzyme sensing applications.

Summary: This paper introduces a novel multi-task learning data-driven model called GBLS Booster for accurately assessing the state of health (SOH) and remaining useful life (RUL) of lithium batteries. The model combines the strengths of GBLS and the CNN-Transformers algorithm-based Booster, and the Tree-structured Parzen Estimator (TPE) algorithm is used for optimization. The study devises 10 healthy indicators (HIs) derived from readily available sensor data to capture variations in battery SOH. The random forest method (RF) is employed for feature refinement and data dimension reduction, while the complete empirical mode decomposition (CEEMDAN) method and the Pearson correlation coefficient are used for noise reduction and data point elimination in RUL prediction. The proposed model demonstrates exceptional accuracy, robustness, and generalization capabilities.
