Recent research has unveiled stable planar hypercoordinate motifs with unconventional geometric arrangements and bonding patterns that facilitate the synthesis of new 2D materials with diverse applications. Among these, yet the design of 2D transition metal systems featuring planar pentacoordinate boron (ppB) is particularly intriguing. Here we address this gap by proposing a novel family of transition metal boride monolayers (MBenes) composed of ppB and heptacoordinate M motifs. The novelty of our MBenes stems from their distinct atomic arrangements and bonding configurations, setting them apart from traditional 2D materials. High-throughput calculations identified 10 stable MBenes (with the stoichiometry of MB, M ​= ​Cr, Fe, Co, Ni, Cu, Mo, Pd, Ag, Pt, Au) with exceptional thermodynamic, dynamic, thermal, and mechanical stabilities attributed to strong B−B covalent bonds and M−B ionic interactions. Notably, five of these MBenes (M ​= ​Ni, Pd, Pt, Ag, Au) hold high promise as topological superconducting materials with superconducting transition temperatures of 2.4–5.2 ​K. This discovery not only enriches the family of topological superconducting materials but also opens new avenues for quantum device development. Meanwhile, FeB monolayer exhibits robust ferromagnetic properties with a high Curie temperature of ∼750 ​K, which is particularly significant for spintronics applications. In addition, NiB and CuB MBenes demonstrate extremely low sodium diffusion barriers (about 30 and 90 ​meV) and high sodium storage capacities (788 and 734 mAh g⁻¹, respectively), making them promising anode materials for sodium-ion batteries (SIBs). This study expands the selection of electrode materials for SIBs and mitigates some existing limitations in battery technology. Overall, these findings underscore the multifunctional potential of MBenes, positioning them as transformative materials for quantum computing, spintronics, and energy storage applications.</div></div>","PeriodicalId":7283,"journal":{"name":"Advanced Powder Materials","volume":"4 3","pages":"Article 100297"},"PeriodicalIF":0.0,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143885946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To enhance the oxidative stability of ether-based electrolytes, the physicochemical properties of various glycol dimethyl ethers are screened, and diglyme (G2) is selected as the sole solvent for the electrolyte. Lithium bis(fluorosulfonyl)imide (LiFSI), a highly dissociative salt, is used as the primary salt; while lithium nitrate (LiNO₃) and lithium difluorophosphate (LiDFP), which have small ionic sizes and strong binding energies, are added as secondary salts.

Additionally, the oxidation stability of the electrolyte is improved and the formed electrode-electrolyte interphase is more uniform and stable, thereby enhancing the electrochemical performance of the cells.

We then summarize previous methods of recycling CBs waste, including clay bricks, asphalt concrete pavement, gypsum, acoustic materials, chemisorption, vector control, and corrosion control. The potential applications of CBs include triboelectric nanogenerator applications, flexible batteries, enhanced metal-organic framework material energy storage devices, and carbon-based hydrogen storage.

Effectively regulating the electronic structure of Pt to enhance CO resistance is crucial for developing high-performance catalysts with robust anti-poisoning capabilities. Herein, the Pt/W@NCNF featured by Pt nanoparticles and atomical dispersed tungsten (W) sites on N-doped carbon nanofibers is developed for CO tolerance HOR catalyst. The presence of W enables the electron transfer from Pt, which promotes electron rearrangement in the Pt-5d orbitals. It not only optimizes the adsorption of H∗ and CO∗ on Pt, but also the OH∗ intermediates adsorbed on the W sites oxidize the CO∗ adsorbed on Pt, thereby retaining more active sites for H₂ adsorption and oxidation. The HOR exchange current density of Pt/W@NCNF reaches 1.35 times that of commercial Pt/C, and the limiting current density decreases by only 3.4% after introducing 1000 ​ppm CO in H₂.

The CQDs with Coulomb blockade effect serve as traps for the migrating of electrons in the dielectrics, while the bonding networks formed by CQDs and PEI further deepen the traps and augment trap density. As a result, the hybrid dielectrics (PEI-NH₂-CQDs) exhibit nearly an order of magnitude higher electrical resistivity than that of pure PEI, leading to an 80% increase in discharge energy density with an energy efficiency of 90% at 200 ​°C compared to pure counterpart.

Nevertheless, the inherent challenges associated with small data obscure these statistical correlations, impeding machine learning models from effectively capturing the underlying patterns, thereby hampering efficient optimization of material properties. This work presents a novel active learning framework that integrates generative adversarial networks (GAN) with a directionally constrained expected absolute improvement (EAI) acquisition function to accelerate the discovery of ultra-high temperature ceramics (UHTCs) using small data. The framework employs GAN for data augmentation, symbolic regression for feature weight derivation, and a self-developed EAI function that incorporates input feature importance weighting to quantify bidirectional deviations from zero ablation rate. Through only two iterations, this framework successfully identified the optimal composition of HfB₂-3.52SiC-5.23TaSi₂, which exhibits robust near-zero ablation rates under plasma ablation at 2500 ​°C for 200 ​s, demonstrating superior sampling efficiency compared to conventional active learning approaches.
