Summary: Based on first-principles calculations, a completely flat borophene monolayer known as chi(2/9) with ideal Dirac nodal line states around the Fermi level has been discovered for the first time. A tight-binding model utilizing the Slater-Koster approach demonstrates that the unique electronic feature of chi(2/9) primarily originates from the interactions of the first-nearest neighbors' p(z) orbitals of boron. Symmetry analysis reveals that the Dirac nodal line in chi(2/9) is guaranteed by the out-of-plane mirror or C-2 rotational symmetry and negligible p(z) orbital coupling. Chemical bonding analysis uncovers the rare electronic properties of this material, which can be attributed to the multicentered pi bonds.

Summary: The stability enhancement mechanism of honeycomb borophene on Ti2C substrate was systematically investigated, and the epitaxial growth model was proposed based on comparative total energy calculations. The results showed that planar honeycomb borophene layer is energetically favorable on Ti2C substrate with strong substrate-induced interactions. Boron adatoms easily migrate and form clusters along hollow sites on the surface, leading to the formation of six-membered boron islands.

Summary: In this study, unique B5 clusters were successfully formed on a monolayer borophene (MLB) on a Cu(111) surface using molecular beam epitaxy and scanning tunneling microscopy experiments. The B5 clusters selectively bind to specific sites of MLB with covalent boron-boron bonds in a periodic arrangement. The close-packed adsorption of B5 clusters facilitates the synthesis of bilayer borophene, exhibiting a domino effect-like growth mode. The successful growth and characterization of uniform boron clusters on a surface enrich the boron-based nano-materials and reveal the essential role of small clusters during the growth of borophene.

Summary: In this study, an improvement strategy for the sensing performance of gold (Au) and silver (Ag) ellipsoid nanoparticles (NP-ELs) was proposed by controlling their size, aspect ratio (AR), and core-shell structure. The sensitivity and figure of merit (FOM) of the Ag-Au NP-ELs were calculated using a multiple oscillator model and discrete dipole approximation (DDA). The results showed that the aspect ratio parameter was more important than particle size in increasing sensitivity and FOM. The core-shell structure and parameters such as shell thickness, particle size, and aspect ratio also affected the absorption spectrum and sensing performance of the Ag-Au NP-ELs. The maximum sensitivity obtained was 597.7 nm/RIU with an FOM of 34 RIU-1.

Summary: Faradic electrode-directed capacitive deionization (faradic-based CDI) is a green and eco-friendly technique with potential in addressing freshwater crisis. However, its practical applications are limited by slow desalination kinetics. In this study, a synergetic strategy combining material design and cell architecture was proposed to improve the desalination rate limit of faradic-based CDI. The integration of ultrasmall Bi nanoclusters impregnated carbon nanofibers as electrodes and a flow-through CDI system resulted in super-fast desalinization and excellent cyclic stability. This research opens up new possibilities for highly-efficient desalination systems based on faradic-based CDI.

Summary: Currently, the Haber-Bosch (HB) process dominates artificial ammonia synthesis. However, concerns over energy consumption and air pollution have led to a growing demand for economical and eco-friendly approaches like electrocatalysis. Through density functional theory calculations, we investigated bimetallic alloys of iron and group-IVA elements for their potential in electrochemical nitrogen reduction reaction (e-N2RR). Our findings showed that alloying iron with group-IVA elements can significantly enhance the e-N2RR activity, with an optimal Fe-Si ratio of 3:1 yielding a theoretical overpotential of only 0.21 V, one of the best results observed. Our work proposes a rational design for practical and economical e-N2RR electrocatalysts, as many of the bimetallic alloys studied have already been synthesized.

Summary: In order to solve the poor cycling stability of faradaic materials in large-scale electrochemical deionization (ECDI) applications, a soft-hard interface was developed using conducting polymer hydrogels (CPHs), specifically polyvinyl alcohol/polypyrrole (PVA/PPy), to distribute Prussian blue analogues (e.g., copper hexacyanoferrate (CuHCF)) uniformly. The soft buffer layer of the hydrogel effectively alleviates the stress concentration of CuHCF during the ion-intercalation process, and the conductive skeleton of the hydrogel provides charge-transfer pathways. The engineered CuHCF@PVA/PPy demonstrates excellent salt-adsorption capacity, fast salt-removal rate, low energy consumption, and cycling stability, making it a promising material for ECDI applications.
