Ultrasonic Atomization Spray Coating of PCL on an Mg‐Based Alloy Enhanced by Plasma Electrolytic Oxidation for Improved Adhesion, Corrosion Resistance, and Biocompatibility

Advanced Engineering Materials, EarlyView.
Plasma electrolytic oxidation is combined with ultrasonic spray deposition of polycaprolactone (PCL) on WE43 magnesium alloy to improve adhesion, corrosion resistance, and cytocompatibility. The hybrid coating demonstrates significantly reduced hydrogen evolution and enhances mechanical bonding, offering a promising strategy for next‐generation ...

Adaptive Beamforming Based on Compressed Sensing with Smoothed l0 Norm

International Journal of Antennas and Propagation, 2015
An adaptive beamforming based on compressed sensing with smoothed l0 norm for large-scale sparse receiving array is proposed in this paper. Because of the spatial sparsity of the arriving signal, compressed sensing is applied to sample received signals ...

Programmable Reconfiguration of Hybrid 4D Chiral Metamaterials via Mechanical and Thermal Stimuli

Advanced Engineering Materials, EarlyView.
A class of hybrid chiral mechanical metamaterials is designed to achieve programmable reconfiguration through soft networks, hinges, and bilayer joints integrated with rigid units. Responsive to mechanical and thermal stimuli, these structures exhibit large volume changes, tunable deformation pathways, and both positive and negative thermal expansion ...

A novel method to remove impulse noise from atomic force microscopy images based on Bayesian compressed sensing

Beilstein Journal of Nanotechnology, 2019
A novel method based on Bayesian compressed sensing is proposed to remove impulse noise from atomic force microscopy (AFM) images. The image denoising problem is transformed into a compressed sensing imaging problem of the AFM. First, two different ways,

Bioinspired Materials, Designs, and Manufacturing Strategies for Advanced Impact‐Resistant Helmets

Advanced Engineering Materials, EarlyView.
This review explores how bioinspired materials, structures, and manufacturing strategies transform helmet design to achieve enhanced impact resistance. Drawing inspiration from nacre, porcupine quills, beetle exoskeletons, and skull architectures, it highlights advances in auxetic lattices, nanocomposites, and functionally graded foams.

Blind Compressed Sensing Parameter Estimation of Non-cooperative Frequency Hopping Signal

Leida xuebao, 2016
To overcome the disadvantages of a non-cooperative frequency hopping communication system, such as a high sampling rate and inadequate prior information, parameter estimation based on Blind Compressed Sensing (BCS) is proposed.
