Two new CPs, Fc-Cu1 and Fc-Cu2, were obtained by self-assembly of CuI with (2-methyl-1,3-dithiolan-2-yl)ferrocene and 1,1′-bis(2-methyl-1,3-dithiolan-2-yl)ferrocene, respectively. Both CPs consist of a similar [{Cu2(µ4-I)(µ2-I)}]n array where ferrocene ligands coordinate via sulfur atoms, leading to a one-dimensional polymeric structure for Fc-Cu1 and a layered 2D architecture for Fc-Cu2. The 2D architecture of Fc-Cu2 improves electrical conductivity, charge transport, and ion diffusion compared to its 1D counterpart, resulting in a higher diffusion-controlled charge storage capacity of 450 C g−1 (areal capacity: 855 mC cm−2) at 1 A g−1. A symmetric supercapattery device assembled using Fc-Cu2 electrodes delivers a maximum energy and power density of 14.5 Wh kg−1 and 6 kW kg−1, respectively, and retains 85% of its initial capacity over 10 000 cycles, demonstrating excellent cycling stability. This study underscores the significance of combining multiple redox-active centers with controlled framework dimensionality in the development of next-generation CP/MOF-based energy storage systems.

Despite being a key diagnostic tool, electromyography (EMG) interpretation is frequently subjective and necessitates expert analysis. New developments in quantum computing allow for hybrid quantum-classical models that improve the processing of biomedical signals. This study introduces a system for automated myopathy identification using EMG signals that is based on Quantum Convolutional Neural Networks (QCNNs). Combining the durability of deep learning with quantum parallelism, the suggested design uses a conventional neural network for classification and quantum circuits for effective feature extraction. The QCNN outperforms both classical CNN and purely quantum baselines in accuracy, precision, recall, F1-score, and ROC-AUC, according to experimental results, which demonstrate that it reaches 96.99% accuracy. The viability of real-Time clinical implementation was also assessed by analyzing inference time and qubit use. Although encouraging, issues with scalability-due to qubit constraints-model interpretability for clinical trust, and generalization to a variety of patient populations still exist. In the era of Noisy Intermediate-Scale Quantum (NISQ), this work shows how QCNNs can be used for medical diagnostics. It also lays the groundwork for further studies into multi-class classification, cross-modal learning, and deployment on actual quantum hardware. © 2025 IEEE.

Efforts have been made to provide an in-depth introduction to CQDs, their classification, various sustainable synthesis methodologies of CQDs, the main functional characteristics of CQDs and techniques to impregnate CQDs inside polymer matrices. Further, the combination of nanoscale CQDs inside the polymer matrix creates a unique array of properties, including tunable photoluminescence, biocompatibility and electrical properties. These tunable properties make CQD–polymer composites potential materials for exploring cutting-edge applications in vibrant domains such as sensing, energy conversion, energy storage, biomedicine, environmental remediation, anti-corrosion, and flame-retardants. The critical review includes current challenges and future potential research directions to inspire researchers to investigate new avenues in the field of CQD–polymer composite materials.
