Abstract Fast charging Lithium-ion batteries (LIBs) is highly required with the massive development of electric vehicle market. Integrating silicon carbon nanotubes (CNTs) has shown great promise for constructing high-rate anodes LIBs. However, current reported axially coated CNTs electrodes fail to provide a robust conductive connection within interfacial layer, causing unsatisfactory rate performance. In this paper, series novel coaxial hollow nanocables SiO x /C composite were presented...

A novel microfluidic chip-based fluorescent DNA biosensor, which utilized the electrophoretic driving mode and magnetic beads-based "sandwich" hybridization strategy, was developed for sensitive ultra-specific detection of single-base mismatch in this study. In comparison with previous biosensors, proposed biosensor has much more robust resistibility to complex matrix real saliva serum samples, shorter analysis time, higher discrimination ability mismatch. These features, as well its...

Optical coherence tomography is radiation-free, and it considered a tool of optical biopsy. Classification normal cancerous tissues very important for the guidance surgeons. Here, we develop morphological feature analysis-based classification (MFAC) method, combining with machine learning to identify tissues. We extract five quantitative features from one OCT image through structured analysis. Five classifiers are involved make classification: support vector machine, K-nearest neighbor,...

Optical coherence tomography (OCT) is widely used in clinical diagnosis due to its non-invasive, real-time, and high-resolution characteristics. However, the inherent speckle noise seriously degrades image quality, which might damage fine structures OCT, thus affecting results. In recent years, supervised deep learning-based denoising methods have shown excellent ability. To train a denoiser, large number of paired noisy-clean images are required, difficult achieve practice, since acquiring...
