Micromotors hold great promise for extensive practical applications such as those in biomedical domains and reservoir exploration. However, insufficient propulsion of the micromotor limits its application crossing biological barriers breaking boundaries. In this study, an ultrafast microbullet based on laser cavitation that can utilize energy a bubble realize own hurtling motion is reported. The experiments are performed using high-speed photography. A boundary integral method adopted to...
Abstract To achieve efficient size tuning of printed microstructures on insulating substrates, an integrated process parameter intelligent optimization design framework for alternating current pulse modulation electrohydrodynamic (AC‐EHD) printing is proposed the first time. The comprised two stages: construction a prediction model and acquisition parameters. stage employs elk herd optimizer(EHO)‐artificial neural network(ANN) to establish mapping relationship between parameters deposited...
Conventional acoustic materials with uniform media which are of fixed impedance and density unable to satisfy the requirements development modern technology in volume, weight, pressure resistance stealth performance. In this paper, composite structures different gradient impedances proposed. The influence forms discrete layering methods on performance is investigated numerically experimentally. It found that structure exponential form improves absorbing low frequency best among all these...
Controlling the nanostructure of conducting polymers (CPs) is essential for enhancing their performance in energy storage applications. Existing CPs often suffer from low effective pseudocapacitance due to poor ion permeability. In this study, we introduce a novel approach using hydrogen-bonded organic frameworks (HOFs) synthesize porous poly(3,4-ethylenedioxythiophene) (PEDOT). We incorporated 3,4-ethylenedioxythiophene (EDOT) into HOF-16 by leveraging flexible hydrogen-bonding...
A Morlet-like wavelet cluster-based method for band-pass filtering and envelope demodulation is described. Via appropriate choice of parameters, a cluster combined with multi-Morlet-like wavelets can be used as filter zero phase shift, flat topped pass-band rapid attenuation in the transition band. It to extract high frequency natural vibration components. The imaginary part Hilbert transformation its real part. This implement component resonance applied fault diagnosis relating bearing...
This paper presents an improved gas sensor based on the dual-excitation of quartz-enhanced photothermal spectroscopy (QEPTS) using a single quartz tuning fork (QTF) for signal detection. The silver coating one side QTF was chemically etched to increase laser power interacted with QEPTS excitation. By etching QTF, reflection structure between other and external flat mirror established. device uses absorption cell optical range length 3 m, making beam interact more completely posing...
This study investigated the enhancement of mechanical and acoustic properties polyurea (PU) composites by incorporating iron microparticles (Fe). The Fe/PU were prepared using a mixing process, where evenly distributed within matrix via stirring. primary purpose this was to explore how varying volumes influence viscoelastic performance composites, with particular focus on applications in underwater stealth technology. Dynamic analysis conducted effect powder volume fraction i.e.,...
In this paper the experiments of detection partial discharges in GIS using ultra high frequency technique is described. The sensors are put outside so they do not bring extra requirements to fabrication and operation GIS. Some steps taken resist external noises. results show that UHF method effective detecting PD avoiding disturbance coronas Nevertheless very large corona, fluorescent tube or radio noise nearby can still disturb measurement. A signal processing by software presented paper....
One of the most important subjects in monitoring GIS is PD detection. The issue that signal weak and sensitive to external noise. In this paper, experiments detection using UHF technique described. results show method effective detecting avoiding disturbance corona. Nevertheless very large corona, fluorescent tube or radio frequency noise nearby can still disturb measurement. A processing by software presented paper. Through procedure wavelet transform, extraction reconstruction analyzed...
Ultrafast Microbullets As the excited cavitation bubble expands and collapses close to polystyrene (PS)/ magnetic nanoparticle (MNP) microbullet, a high pressure is generated, which violently propels microbullet realize its hurtling motion. This enormous energy of expected provide with ability break through barriers such as reservoir boundaries. More details can be found in article number 2207565 by Shuai Li, Xiaocong Chang, Dekai Zhou, co-workers.
Space-Air-Ground Integrated Networks (SAGINs) have been widely recognized as an important 6G hierarchical architecture for satisfying content caching and delivering demands of users. However, the complicated communication conditions dynamic network topology pose great challenges SAGINs to meet diversified Quality Service (QoS) requirements Caching popular contents on Unmanned Aerial Vehicles (UAVs), which are closer ground end users, can efficiently improve QoS decrease pressure satellites....
