Abstract ：
In response to the need for multiple complete bearing degradation datasets in traditional deep learning networks to predict the impact on individual bearings, a novel deep learning-based rolling bearing remaining life prediction method is proposed in the absence of fully degraded bearng data. This method involves processing the raw vibration data through Channel-wise Attention Encoder (CAE) from the Encoder-Channel Attention (ECA), extracting features related to mutual correlation and relevance, selecting the desired characteristics, and incorporating the selected features into the constructed Autoformer-based time prediction model to forecast the degradation trend of bearings' remaining time. The feature extraction method proposed in this approach outperforms CAE and multilayer perceptual-Attention Encoder in terms of feature extraction capabilities, resulting in reductions of 0.0059 and 0.0402 in mean square error, respectively. Additionally, the indirect prediction approach for the degradation trend of the target bearing demonstrates higher accuracy compared to Informer and Transformer models, with mean square error reductions of 0.3352 and 0.1174, respectively. This suggests that the combined deep learning model proposed in this paper for predicting rolling bearing life may be a more effective life prediction method deserving further research and application.

Abstract ：
Rotary friction welding dissimilar metals of AA1100 aluminum to H59 brass was conducted with a phi 20-mm cylinder sample. The friction pressure is 90 MPa and the welding time is 15 s. Preheating to 600 K and 873 K were conducted to soften H59 brass (i.e., the hard side), so that the both metal with great differences in physical properties could deform simultaneously at the friction interface. The deformation rate was calculated by solving constitution equation, and the necessary parameter interfacial temperature was obtained by infrared thermal imaging analysis. SEM observation and EDS analysis were jointly conducted to clarify microstructure and elements distribution across the interface. The results show that the joint produced without preheating brass contain some unwelded areas and therefore presents lower tensile strength (30 MPa) just 33% of the aluminum base metal. Preheating results in large temperature difference (166 K) on both side of interface. Ratio of deformation rate psi is defined to characterize deformations' difference. psi drops two orders of magnitude (from 600 decrease to 5) when brass was preheated to 600 K, but raising preheating temperature to 873 K, its value has minor change (from 5 decrease to 1). Smaller psi value implies a comparative shear deformation and viscoplastic flow on both sides' surface. The welding interface presents layered structure, which is composed of CuAl2 + CuAl + Cu9Al4 laminate. With a thin IMCs layer (3 mu m), the joint has highest tensile strength 63 MPa.

Abstract ：
The Surface plasmon resonance (SPR) of metal materials has been widely used in photocatalysis, light sensing, biomarkers, solar cells and other fields. In this study, the surface plasmon characteristics of tungsten (W) nanowires with different diameters and lengths are analyzed using the finite element method. The thermal effect in the gap of crossed nanowires induced by the plasma resonance is studied. Results show that the resonance peak shifts red, and the resonance intensity increases with the increase in diameter. The increasing diameter results in decreasing electric field intensity and heat in the gap of the crossed tungsten (W) nanowires. The frequency of resonance peaks almost remains unchanged with increasing length. The two to six wave belly plasma modes are visible with increasing nanowire length. With exposure to incident light, the SPR in the shortened spacing results in increasing electric field intensity and the generated heat of gap between the two crossed tungsten (W) nanowires. Once the two crossed nanowires are welded, the heat production in the crossed part decreases, which indicates the self-limitation of plasma welding.

Abstract ：
Cu nanowires and a nanoporous Ag matrix were fabricated through directional solidification and selective dissolution of Ag-Cu eutectic alloys. Ag-39.9at.%Cu eutectic alloys were directionally solidified at growth rates of 14, 25, and 34 mu m/s at a temperature gradient of 10 K/cm. The Cu phase in the Ag matrix gradually changed from lamellar to fibrous with an increase in the growth rate. The Ag matrix phase was selectively dissolved, and Cu nanowires of 300-600 nm in diameter and tens of microns in length were prepared in 0.1 M borate buffer with a pH of 9.18 at a constant potential of 0.7 V (vs. SCE). The nanoporous Ag matrix was fabricated through selective dissolution of Cu fiber phase in 0.1 M acetate buffer with a pH of 6.0 at a constant potential of 0.5 V (vs. SCE). The diameter of Ag pores decreased with increasing growth rate. The diameter and depth of Ag pores increased when corrosion time was extended. The depth of the pores was 30 mu m after 12 h.

Abstract ：
In order to fabricate fibrous eutectic Si, the selective etching of industrial Al-Si eutectic alloys directionally solidified at different growth rates and modified by different amounts of Sr was studied. Flake eutectic and fibrous Si were obtained by selective etching of non-modified, Sr-modified or directionally solidified Al-Si eutectic alloys. The optimal amount of Sr for fabricating branching eutectic Si was 0.04-0.07%. Through directional solidification with a high enough growth rate (more than 200 mu m/s), lamellar eutectic Si transforms to fibrous eutectic Si for use in non-modified Al-Si eutectic alloys. The potentiodynamic polarization and cyclic voltammetry methods were used to test the corrosion behavior of non-modified and Sr-modified Al-Si eutectic alloys. With a constant potential of 0.5 V in HCl solution, non-modified Al-Si eutectic alloys displayed initial pitting corrosion and subsequent spalling corrosion, and 0.04% Sr-modified samples displayed uniform pitting corrosion. Compared with non-modified Al-Si eutectic alloys, Sr-modified samples displayed better corrosion resistance with lower current density and shallower pit depth during the same etching conditions.

Abstract ：
This paper aims to clarify the phase composition in each sub-layer of tandem absorber TiMoAlON film and verify its thermal stability. The deposited multilayer Ti/(Mo-TiAlN)/(Mo-TiAlON)/Al2O3 films include an infrared reflectance layer, light interference absorptive layers with different metal doping amounts, and an anti-reflectance layer. The layer thicknesses of Ti, Mo-TiAlN, Mo-TiAlON, and Al2O3 are 100, 300, 200, and 80 nm, respectively. Al content increases to 12 at.% and the ratio of N/O is nearly 0.1, which means nitride continuously changes to oxide. According to X-ray Diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM) results, the diffraction peak that appears at 2 theta = 40 degrees demonstrates that Mo element aggregates in the substitutional solid solution (Ti,Al)(O,N) columnar grain. TiMoAlON films have low reflectivity in the spectrum range of 300-900 nm. When Al content is more than 10 at.%, absorptivity is almost in the spectrum range from visible to infrared, but absorptivity decreases in the ultraviolet spectrum range. When Al content is increased to 12 at.%, absorptivity alpha decreases by 0.05 in the experimental conditions. After baking in atmosphere at 500 degrees C for 8 h, the film has the highest absorptivity when doped with 2 at.% Mo. In the visible-light range, alpha = 0.97, and in the whole ultraviolet-visible-light near-infrared spectrum range, alpha = 0.94, and emissivity epsilon = 0.02 at room temperature and epsilon = 0.10 at 500 degrees C.
