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}

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.

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. Microstructural analysis reveals that the exceptional performance stems from the formation of a highly viscous HfO₂-SiO₂-Ta₂O₅-HfSiO₄-Hf₃(BO₃)₄ oxide layer, which provides effective oxygen barrier protection.
