The ability to mix many different metal cations in a single-phase nanoscale oxide is critical for property adjusting and new material discovery. However, synthesizing multicomponent high-entropy oxides (HEOs) consisting of over ten metal cations remains a challenge due to dissimilarity and immiscibility among these elements. Herein, we report a scalable top-down chemical dealloying method to mix up to 16 metal cations in a single-phase nanostructured HEO. When applied as anode materials in Li-ion battery, our HEO exhibits an excellent cycling stability. This study greatly expands the composition space of nanoscale HEOs and provides an interesting route for new materials discovery. © 2024, The Authors. All rights reserved.

Tuning competition between charge order and superconductivity in the square-lattice t−t′−J model

Recently, a flurry of works have found strong competition between charge density wave (CDW) and superconductivity (SC) in the doped Hubbard and t−J models on the square lattice. Interestingly, some recent results suggest that the electron-phonon coupling may suppress CDW order and enhance SC. In this work, we consider the square-lattice Hubbard model with the Holstein or Su-Schrieffer-Heeger electron-phonon coupling at the large-U and antiadiabatic (infinite phonon frequency) limits, which gives an effective t−J model with either a density attractive interaction V or a JP term that contributes a larger spin exchange and a density repulsive interaction. To explore how these effective couplings may tune the competition between CDW and SC, we implement the density matrix renormalization group simulations on the t−t′−J model with V or JP coupling. We focus on the six-leg cylinder system with the next-nearest-neighbor hopping t′, which hosts partially filled stripe and d-wave SC in phase diagram. By tuning t′/t>0 and V or JP, we establish two quantum phase diagrams at 112 doping ratio. In the SC phases, the increased V or JP coupling can enhance the quasi-long-range SC order, consistent with some previous findings. Nonetheless, no SC emerges when the partially filled stripe phase disappears with increased V or JP. Instead, the system has a transition to either a phase-separation-like regime or a filled stripe phase. On the other hand, with increased t′/t, not only the partially filled stripe but the phase separation and filled stripe can also be tuned to SC phase. Our results suggest that although V and JP couplings may strengthen hole binding, the hole dynamics controlled by t′/t appears to play a more crucial role for obtaining a SC in the t−J model.

The rational development of a versatile tool capable of rapid and cyclic detection of nerve agents is of great significance due to their extreme toxicity. Herein, we report a reversible colorimetric and ratiometric fluorescent probe (DMC-Py) for rapidly and cyclically detecting nerve agent mimic (diethyl chlorophosphate, DCP) on the base of intramolecular charge transfer (ICT) mechanism. When exposed to DCP, the pyridine unit of DMC-Py is quickly converted to pyridinium salt ( © 2024, The Authors. All rights reserved.

PolarBEVU: Multi-Camera 3D Object Detection in Polar Bird's-Eye View via Unprojection

3D object detection from a Bird's Eye View (BEV) has emerged as a novel perception paradigm for autonomous driving scenarios. While most current 3D object detection methods still rely on the conventional Cartesian coordinates, they fail to align with the non-aligned coordinate system inherent in image geometry. The Polar coordinates, on the other hand, better fit with the geometric shape corresponding to the perception of cameras. However, transforming between coordinate systems introduces distortions in the perception information, resulting in issues such as "Weak Adaptability to Heatmap Distribution"and "Offset in the Center Point of the Bounding Box."To address these challenges, this paper proposes a cutting-edge 3D object detection model named PolarBEVU, which leverages the bird's-eye view under the Polar coordinates along with multi-camera unprojection. The model introduces an innovative "Deformable Uniform Heatmap Distribution"method that adjusts heatmap computations based on box shapes, generating high-quality heatmaps and effectively resolving the issue of "Weak Adaptability to Heatmap Distribution."Moreover, the model incorporates the concept of "Dynamic High-risk Regression Region"to enhance the accuracy and robustness of the center point regression at the bounding box, thus mitigating the issue of "Offset in the Center Point of the Bounding Box."In extensive experiments on the nuScenes dataset, PolarBEVU achieves impressive results with 49.9% mAP and 57.4% NDS on the test set, surpassing other comparative approaches and reaching the state-of-the-art (SOTA) performance among methods utilizing Polar coordinates. This clearly demonstrates the efficacy and superiority of PolarBEVU. In addition, the model is successfully deployed on Nvidia Jetson AGX Orin, showcasing real-time inference speeds of 31.42ms. These findings affirm PolarBEVU's potential for practical applications. Code is available at https: //***/JLUrob/PolarBEVU. © 2025 IEEE.
