Recently a dark matter–electron (DM–electron) paradigm has drawn much attention. Models beyond the standard halo model describing DM accelerated by high energy celestial bodies are under intense examination as well. In this Letter, a velocity components analysis (VCA) method dedicated to swift analysis of accelerated DM–electron interactions via semiconductor detectors is proposed and the first HPGe detector-based accelerated DM–electron analysis is realized. Utilizing the method, the first germanium based constraint on sub-GeV solar reflected DM–electron interaction is presented with the 205.4 kg·day dataset from the CDEX-10 experiment. In the heavy mediator scenario, our result excels in the mass range of 5–15 keV/c2, achieving a 3 orders of magnitude improvement comparing with previous semiconductor experiments. In the light mediator scenario, the strongest laboratory constraint for DM lighter than 0.1 MeV/c2 is presented. The result proves the feasibility and demonstrates the vast potential of the VCA technique in future accelerated DM–electron analyses with semiconductor detectors.

Electrochemical hydrogen permeation method is believable for evaluating the intrinsic hydrogen permeation resistance because its room-temperature operation. However, the control of electrochemical parameters for hydrogen permeation testing has been seldom reported. In this study, we discussed the effects of anode background current, cathode current density and cycle times on electrochemical permeation behavior of CLF-1 RAFM steel. Results show that the anode background current below 1μA can ensure the accuracy of the permeation test. There exists a diffusion delay for the first permeation loop of CLF-1 steel because of hydrogen trap effect, which can be eliminated by annealing the steel at temperature of 740℃ for 2h. For the second and third permeation loops of CLF-1 steel, sample with a high cathode current density tends to have a high permeation signal because of corrosion. Plating a protective nickel film can reduce the corrosion impacts for hydrogen permeation test. The effect of hydrogen traps and corrosion on the permeation behavior was discussed in detail. Our study provides a promising approach for hydrogen permeation testing and hydrogen trap detection at room temperature. © 2023, The Authors. All rights reserved.

One-step selectively photocatalytic phenol hydroxylation to produce Dihydroxybenzenes (DHB) is an attractive and challenging strategy. However, the rapid recombination of photogenerated carriers existed in single component photocatalyst seriously hinders the photocatalytic efficiency. The heterojunction strategy can optimize the band structure of the photocatalyst, and effectively improve the carriers’ separation and transfer during the photocatalytic process. Herein, we successfully designed and prepared a 3D TiO2@Ni3Fe1-LDH core-shell heterostructure photocatalyst by coupling TiO2 nanorods with Ni3Fe1-LDH nanosheets for the photocatalytic phenol hydroxylation to produce DHB. The results showed that the 3D TiO2@Ni3Fe1-LDH core-shell heterostructure had a suitable energy band structure for the photocatalytic phenol hydroxylation and the heterostructure accelerated the carriers’ separation and transfer. Meanwhile, the high porosity and abundant active sites were conducive to the adsorption of H2O2 and the photogenerated carriers transfer efficiency from the photocatalyst to H2O2. The 3D TiO2@Ni3Fe1-LDH core-shell heterostructure showed excellent photocatalytic performance of phenol hydroxylation, where the phenol conversion was 48.6%, and the selectivity of DHB was 81.1% at 25 °C and 4 h of light illumination. Furthermore, the as-prepared photocatalysts exhibited good stability after four cycles of experiment. This work provided a convenient and efficient method for the green synthesis of DHB. © 2024, The Authors. All rights reserved.

Doping solute atoms into alloys to modulate local lattice states and thereby influence defect dynamics represents an effective strategy for developing irradiation-resistant materials. The selection of solute species, as a critical tuning parameter, has gained extensive research attention. However, their effects on the evolution of irradiation defects, particularly the details of defect interactions, remain incompletely understood. Here, we employ in-situ transmission electron microscopy to elucidate the distinct evolution patterns of irradiation-induced dislocation loops and helium bubbles in Ti-, Zr-, and Nb-doped Mo-5Re single-phase solid solution alloys. Quantitative analysis demonstrated irradiation resistance enhancement across all doped systems, with Nb exhibiting a stronger suppression of both loop and bubble growth. Notably, Nb more strongly altered loop interaction modes, as evidenced in inhibiting loop climb, slowing down loop coalescence, and impeding the point defects flux to the pre-formed loops. Theoretical analysis revealed that Ti, Zr, and Nb gradually increased the critical climb force required for loop climb. First-principles calculations further confirmed the same rising trend in defect formation energies and migration energy barriers around Ti, Zr, and Nb. Additionally, differential interactions between doping solutes and substitutional/interstitial He indicated the dominance of interstitial-mediated mechanism under current conditions. Distinct He formation and diffusion behaviors around doped solutes explained the different bubble characteristics in these alloys. These findings reveal the critical role of doping solute selection in tailoring defect behavior, providing valuable insights for the chemical optimization and design of advanced nuclear materials. © 2025 Acta Materialia Inc.

Transmission lines often passed through forests. When the climate is hot and before and after the Tomb-sweeping Day every year, mountain fire accidents often occur, which affects the transmission lines. The most important impact is the tripping of the transmission lines, which seriously affects the safe operation of the power grid influences. This paper builds a test platform for the influence of smoke on the insulation of transmission lines, designs a smoke test plan, conducts an experimental study on the influence of smoke on the air insulation characteristics of transmission lines, and verifies the smoke concentration on single-phase, three-phase and inter-phase insulation through experiments. The influence of character-This article judges whether it has an influence on the insulation characteristics of transmission lines by observing the relative leakage current of smoke. The effect of smoke on the breakdown voltage was verified through experiments. Through comparative experiments at different temperatures, it was studied whether mountain fire smoke would affect the air insulation characteristics. Experimental studies have shown that pure smoke has little effect on the insulation characteristics of transmission lines.

Condition identification is the basis of induction motor condition monitoring. However, existing non-invasive methods have different degrees of problems in accuracy, robustness and generalization. To solve this challenge, this paper proposes a new method to identify induction motor working conditions, including speed and load torque. This method is a physical-empirical hybrid model method, which combines the advantages of a clear mechanism of the physical model method and easy implementation of the empirical model method. The proposed method introduces the multi-dimensional empirical information contained in the stator current, and the fitting function adopted has a solid physical basis, so the proposed method has the innate advantages of high identification accuracy and strong robustness. The experimental results show that the working conditions identified by the proposed method are in good agreement with the real values. Moreover, by comparing with other existing condition identification methods, the advantages of the proposed method in condition identification accuracy are further verified.

The coupling relationship of the hydraulic drilling rig, as a complex mechanical system with mechanical-electric-hydraulic, is very important to its working performance. The internal leakage of the hydraulic motor (a direct drive component of the drilling rig) is easy to appear and difficult to be directly observed, so it is especially important to analyze the working performance of the drilling rig under the internal leakage condition of the hydraulic motor. This paper focuses on the analysis of mechanical-electric-hydraulic dynamics of hydraulic drilling rig under no loading and loading. Firstly, a coupling dynamics model of the drilling rig is established theoretically and then the dynamic response of the drilling rig is analyzed by simulation. Secondly, the leakage sensitivity simulation and analysis of hydraulic motor is performed to explore the impact of the internal leakage of the hydraulic motor on the dynamic response of the drilling rig. Finally, a dynamic response test platform of the drilling rig is built, the experiment result agrees better with the simulation result under different leakage ratios of the hydraulic motor, and the leakage ratio of the hydraulic motor is sensitive to the rotational speed and load torque of the drilling rig. © 2020, Chinese Mechanical engineering Society.

The Qinghai-Tibet Plateau contains the most abundant clean energy such as hydropower, wind and solar in the world. However, it is very difficult to add overhead transmission lines on the ground due to the complex geographical environment. The large-capacity tunnel cables which is less affected by the earth surface environment, may play an important role on the energy transmission in such area. Based on the cable thermal circuit model, the electrical-magnetic-thermal multiphysics coupling of the cable is modeled in COMSOL Multiphysics. The parameter changes of the material during the temperature rising process, the influence of different ventilation conditions and different current-carrying capacities on the changes of the cable temperature field are quantitatively analyzed. The results show that the proposed model is valid in certain conditions. The research on the current carrying capacity and thermal effect of tunnel cables is of great significance for the transportation and consumption of large-scale clean energy resources.

Deep neural networks (DNNs)-based battery remaining useful life (RUL) prognostics models suffer from high computational costs, long inference times, and a tendency to overfit, posing significant challenges for deployment on memory-constrained edge devices. To address this, LDNet-RUL, a lightweight yet high-performance model, is proposed for lithiumion battery lifetime prognostics. Specifically, a deformable depthwise convolution unit is designed that efficiently adapts to variations in input features with relatively low computational cost, which leverages fewer parameters and an adaptive receptive field to capture battery degradation dynamics. A multi-scale feature extraction method is introduced to extract degradation features from both short-term and long-term data during the battery charging process, which makes the method applicable to various battery charging protocols. To address overfitting and accelerate model inference, an adaptive channel selector, an adaptive residual connector, and a progressive dimensionalitygrouped bottleneck filter are incorporated to refine feature selection and reduce the model's complexity, boosting the model's overall performance. Experiments on vehicle lithium-ion battery datasets demonstrate that LDNet-RUL achieves state-of-the-art (SOTA) performance, with average RMSE of 0.23 and Score of 0.49. The model is lightweight, with only 7.92K parameters, achieves inference times of 3.94ms on GPU and CPU, and 5.39ms on the NVIDIA Jetson TX2. © 1986-2012 IEEE.
