Although metal nanowires (NWs), such as silver NWs, are ideal materials for flexible transparent electromagnetic shielding films, the challenge of obtaining absorptive films with high transmittance and efficiency (SE) still exists. To address this issue, study used iron (Fe NWs) excellent microwave absorbing properties to construct structures ordered NW distributions. A series polyethylene terephthalate (PET)/Fe NWs/poly (3,4-ethylenedioxythiophene) (PEDOT) interference (EMI) were prepared...
The health condition of mechanical systems can be characterized by wear debris in lube oil. Therefore, detection is necessary for the fault prediction and diagnosis systems.

An induction coil placed field, induced voltage generated when oil pipe flows through A mathematical model established, output signal similar to that three-coil sensor. experimental results show capable detecting 25-μm ferromagnetic...
In this study, we successfully prepared core-shell heterostructured nanocomposites (Fe NWs@SiO2), with ferromagnetic nanowires NWs) as the core and silica (SiO2) shell. The composites exhibited enhanced electromagnetic wave absorption oxidation resistance were synthesized using a simple liquid-phase hydrolysis reaction. We tested analyzed microwave properties of Fe NWs@SiO2 varied filling rates (mass fractions 10 wt%, 30 50 wt% after mixing paraffin). results showed that sample filled had...
One-dimensional iron–nickel (Fe–Ni) heterogeneous nanowires with superior electromagnetic wave (EMW) absorption were successfully prepared by a magnetic-field-assisted liquid-phase reduction method. The properties of the absorber controllably tuned changing atomic molar ratio Fe to Ni. composite an Fe:Ni 1:1.5 exhibited finest EMW characteristics.

Reducing the filling content of high-density ferromagnetic particles is a key prerequisite for obtaining lightweight absorbers. To this end, large iron nanowires (Fe NWs) with high length-diameters, uniform length approximately 21 μm and diameters 60 nm were synthesized through facile magnetic field-induced in situ reduction method without templates surfactants. The phase structures, micromorphology high-aspect-ratio Fe NWs analyzed, electromagnetic properties NWs-paraffin composites...
This study proposes a lightweight convolutional neural network with an octave-like convolution mixed block, called OLCMNet, for detecting driver distraction under limited computational budget. The OLCM block uses point-wise (PC) to expand feature maps into two sets of branches. In the low-frequency branches, we perform average pooling, depth-wise (DC), and upsampling obtain low-resolution map, reducing spatial redundancy connection density. high-frequency expanded map original resolution is...
