Structural evolution and electronic properties of doped boron clusters Ta2Bn (n = 10 ∼ 20): Ta2B16 and Ta2B18 with strong aromaticity

Results in Physics, 2023
In this work, we combine the CALYPSO method with DFT calculations to conduct a comprehensive structural search of Ta2Bn (n = 10 ∼ 20) clusters. Among all the candidate structures obtained by CALYPSO searching, the structures of ground state Ta2Bn ...

Gold(III) Complexation in the Presence of the Macropolyhedral Hydridoborate Cluster [B₂₀H₁₈]²⁻

Inorganics, 2022
Gold(III) complexation with the octadecahydrido-eicosaborate anion [B20H18]2− was studied for the first time. It was found that when gold(III) complexes [Au(L)Cl2]BF4 (L = bipy, phen) reacted with [B20H18]2−, complexes [Au(L)Cl2]2[B20H18] were isolated ...

Mechanical Behavior and Fracture Mechanisms of MXene/PVDF Nanocomponsites: In Situ Characterization and Multiscale Analysis

Advanced Functional Materials, EarlyView.
Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...
