This paper experimentally demonstrates the operating principles of a near-field multiferroic antenna. The antenna uses piezoelectric lead-zirconate-titanate stack to apply time varying strain magnetoelastic iron gallium Fe80.77Ga19.23 (FeGa) rod. voltage induced controls net magnetization FeGa rod generate oscillating magnetic fields in free space surrounding Direct experimental measurements mechanical force, strain, field, and flux inside were collected show strong correlation with dynamic...
Understanding and predicting the properties of inorganic materials is crucial for accelerating advancements in science driving applications energy, electronics, beyond. Integrating material structure data with language-based information through multi-modal large language models (LLMs) offers great potential to support these efforts by enhancing human-AI interaction. However, a key challenge lies integrating atomic structures at full resolution into LLMs. In this work, we introduce...
Water jet-assisted rock breaking is a conventional method for shale gas extraction. However, the complex conditions of deep reservoirs, including elevated temperatures and intricate stratification, obscure rock-breaking mechanisms jets. Therefore, this study conducted high-pressure water jet impact experiments on with five bedding angles (0°, 30°, 45°, 60°, 90°) four (room temperature, 100, 150, 200 °C). Computed tomography (CT) three-dimensional reconstruction techniques were used to...
The utilization of abrasive water jet (AWJ) has garnered notable attention in subsurface engineering, as well unconventional natural gas development, geothermal energy extraction, and tunnel excavation. efficiency construction operations is contingent upon rock fragmentation, which controlled by AWJ parameters properties. Currently, the parameter settings for fragmentation predominantly rely on empirical approaches, existing prediction models have large errors due to a limited number...
