Abstract The manipulation of fast, unidirectional motion for large droplets shows important applications in the fields fog collection and biochemical reactions. However, driving (>5 μL) to move directionally quickly remains challenging due nonnegligible volume force. Herein, we fabricated a scalable, bionic peristome substrate with microcavity width 180 μm using 3D printing method, which could unidirectionally drive water droplet (~8 at speed reaching 12.5 mm/s by temperature-responsive...
High-quality diamond-like carbon (DLC) films are renowned for their exceptional hardness, low friction coefficient, and superior chemical stability. These properties make DLC exceptionally suitable protective coatings in optical, mechanical, aerospace, military applications. Thick with outstanding mechanical were deposited on DC53 die steel using a mixed energy plasma generated by filtered cathodic vacuum arc (FCVA) device. The structural, tribological, optical of the tested Raman, surface...
Copper-doped hydrogenated amorphous carbon (Cu-doped a-C:H) films were synthesized using copper as the cathode and C2H2 precursor. The result shows that negative bias voltage can affect composition microstructure of nanocomposite films. With increasing, Cu content first increases in range 50~300 V then declines with higher voltage, while deposition rate decreases continuously. stress sp3 present a similar trend increasing during from 50 to 200 decreasing voltage.
The innovation ecosystem is the relatively stable state that constitutes behavioural game of main body, and triple helix key to construct ecosystem. This paper explores interactions between in by constructing an evolutionary model clarify their behaviour choices influencing factors. And further analyse interaction regulations subjects through parametric simulation. Based on results modelling, strategies are proposed maintain effective operation under three parties' evolution. research idea...
Multi-features system, as an effective method to improve the performance of biometric-based identification, has been one hot research fields on personal identification. In this paper, a novel finger-vein recognition based feature level fusion global and local features is proposed. First, texture information characterized using Gabor filter framework, extracted by moment invariant method. Then, global-local vectors (GLFVs) from finger-veins are generated canonical correlation analysis (CCA)...
Identifying defective software entities is essential to ensure quality during development. However, the high dimensionality and class distribution imbalance of defect data seriously affect prediction performance. In order solve this problem, paper proposes an Ensemble MultiBoost based on RIPPER classifier for imbalanced Software Defect data, called EMR_SD. Firstly, algorithm uses principal component analysis (PCA) method find out most effective features from original set, so as achieve...
Nanocomposite ZrCN films consisting of nanocrystalline grains embedded in nitrogen-doped amorphous carbon film are deposited by filtered cathodic vacuum arc technology under different bias voltages ranging from 50 to 400 V. The influence voltage on the characterization and mechanical properties investigated x-ray diffraction, photoelectron spectroscopy, scanning electron microscopy, transmission Raman spectroscopy nano-indentation. has a subtle effect grain size, which is around 9.5 nm keeps...
As a volatile air pollutant, formaldehyde can enter people's living environment through interior decoration, furniture and paint, causing serious harm to human health. Therefore, it is necessary develop sensor for the real-time detection of in low concentrations. According chemical interaction between amino groups formaldehyde, MIL-101(Cr) aminated-material-based cantilever was prepared, which ethylenediamine- functionalized named ED-MIL-101(Cr)) showed best gas sensing performance. Using...
Diaphragmatic electromyogram (EMGdi) is a crucial electrophysiological signal that contains information about human respiration. Although it practical to record surface EMGdi (sEMGdi) noninvasively and conveniently by placing electrodes over chest skin, extraction of such weak sEMGdi from noise condition challenging task, limiting its clinical use compared with esophageal EMGdi. In this paper, novel method presented for extracting high-noise based on fast independent component analysis...
In this paper, new two-component supramolecular gels via 2,2-bis(4-carboxyphenyl)hexafluoropropane and N-(4-Aminobenzoyl)-L-glutamic acid diethyl ester have been prepared tested in ethanol/water mixed solvents. Scanning electron microscope (SEM), Transmission (TEM), powder X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR) were measured to characterize the morphology nanostructure of gels. The obtained experimental data reveal that different solvents ratios play an...
