“…5 c, confirms the significant contribution of C2 and C3 near the Fermi level, reinforcing their roles in defining the material's electronic behavior. Consistent with previously reported findings, the p z orbitals, which are key in forming π-type frontier states, play a central role in determining the electronic properties of in-plane extended carbonaceous materials 41 , 42 . Additionally, the p x and p y orbitals contribute to the material's deeper electronic bands through the hybridization with σ bonds, highlighting the complex interplay of orbital contributions to the overall electronic structure.…”

Graphene allotropes with varied carbon configurations have attracted significant attention for their unique properties and chemical activities. This study introduces a novel two-dimensional carbon-based material, termed Graphsene (GrS), through theoretical study. Comprising tetra-, penta-, and dodeca-carbon rings, GrS’s cohesive energy calculations demonstrate its superior structural stability over existing graphene allotropes, including graphyne and graphdiyne families. Phonon dispersion analysis confirms GrS’s dynamic stability and its relatively low thermal conductivity. All calculated GrS elastic constants meet the Born criteria, ensuring mechanical stability. Ab-initio molecular dynamic simulations show GrS maintains its structure at 300 K. HSE06 calculations reveal a narrow electronic bandgap of 20 meV, with the electronic band structure featuring a highly anisotropic Dirac-like cone due to its intrinsic structural anisotropy along armchair and zigzag directions. Notably, GrS is predicted to offer exceptional catalytic performance for the oxygen reduction reaction, favoring the four-electron reduction pathway with high selectivity under both acidic and alkaline conditions. This discovery opens promising avenues for developing metal-free catalyst materials in clean energy production.

Biosensors are analytical tools that integrate a biological element with a physicochemical detector in order to quantify the existence or concentration of chemicals, biomolecules, or other biological elements for human health monitoring purposes. Electrochemical techniques for biological analyte detection include the use of electrochemical sensors to identify and quantify the existence and concentration of biological molecules. These techniques are often used because of their high sensitivity, specificity, quick reaction time, and the possibility of being made smaller in size, but still, the research problem in electrochemical‐based biosensing largely revolves around improving biosensors′ sensitivity, selectivity, stability, and response time. Borophene, an intriguing and novel substance within the domain of two‐dimensional (2D) materials, emerges as a highly promising protagonist in the continuous and dynamic history of nanoscience and nanotechnology. Borophene, characterized by its distinctive electronic, mechanical, and thermal properties, enthralls scientists due to its atomic structure consisting exclusively of boron atoms organized in a honeycomb lattice. In recent years, borophene hybrids and composites have emerged as potentially fruitful avenues for expanding their utility in numerous fields and improving their properties. In addition, borophene and its hybrid systems hold significant potential to overcome the limitations of current electrochemical‐based biosensors. By leveraging their unique properties—such as high surface area, chemical versatility, and mechanical strength—these materials can improve biosensors′ limitations. Moreover, the integration of borophene with other materials can further optimize performance, paving the way for advanced and practical biosensing solutions. This perspective presents a synopsis of recent developments in biosensing composites and hybrids based on borophene, including polymers and other nanomaterials. In addition, we emphasized the remarkable characteristics of borophene hybrids, which permit the detection of biological analytes such as proteins, nucleic acids, and small molecules in a sensitive and selective manner. Additionally, a summary of the computational investigations into analyte detection utilizing borophene‐based systems has been provided. In a nutshell, we discussed the challenges and future directions in the field, outlining opportunities for further innovation and optimization of borophene‐based biosensing platforms.
