2023年6月1日 · Here, we explored the nonlinear optical properties of a novel MXene, Ta 2 C, and demonstrated a femtosecond fiber laser with a Ta 2 C-based saturable absorber (SA). First-principles calculations were employed to fully reveal the …

2024年9月15日 · Herein, we synthesize a new member of double transition metal (DTM) MXenes (out-of-plane ordered Ti 2 TaC 2 MXene) by alloying Ta species at the M−sites of Ti 3 C 2 MXene, reveal its atomic arrangement via density function theory (DFT) calculation and experimental characterization, and further evaluate its electrochemical performance and ...

In materials science, MXenes (pronounced "max-enes") are a class of two-dimensional inorganic compounds along with MBenes, that consist of atomically thin layers of transition metal carbides, nitrides, or carbonitrides.

First-principles simulations analyze vacuum thickness effects on 2D Ta₂C MXene’s properties. Structure editing in WIEN2K generates varied vacuum thicknesses. Vacuum thickness significantly impacts Ta₂C MXene’s electronic, optical, and thermodynamic properties.

在此，精心设计并初步合成了一种新颖的面外有序双过渡金属 MXene （Ti2TaC2），其中 Ti 原子优先位于外部过渡金属层，而 Ta 原子占据中间层。 理论计算证明，在 Ti3C2 MXene 中引入 Ta 物质扩大了功函数，使 d 带中心接近费米能级，并增加了 d 轨道的状态密度。

Here, we explored the nonlinear optical properties of a novel MXene, Ta C, and demonstrated a femtosecond fiber laser with a Ta C-based saturable absorber (SA). First-principles calculations were employed to fully reveal the structural and electronic properties of the Ta C MXene.

2022年9月8日 · In this study, MXene acts as the conductive matrix of Pd/Pt nanoparticles, and DNA is adsorbed on the surface of MXene by π-π stacking (figure 11(d)), which promotes the growth of Pd/Pt nanoparticles. The sensor is prepared by depositing MXene/DNA/Pd/Pt suspension on a glassy carbon electrode, and then immobilizing with Nafion solution.

2023年6月8日 · Two-dimensional (2D) lateral heterostructures (LH) combining Ti2C and Ta2C MXenes were investigated by means of first-principles calculations. Our structural and elastic properties calculations show that the lateral Ti2C/Ta2C heterostructure results in a 2D material that is stronger than the original isolated MXene

MXene films, due to their low cost, high conductivity, and excellent durability under different deformation conditions, are highly competitive in bioelectronic device applications compared with traditional carbon-based materials. Herein, a novel out-of-plane ordered double transition metal MXene (Ti2TaC2) is elaborately designed and originally ...

2024年9月15日 · TaC MXene nanosheets serves as a conductive substrate, addressing the poor conductivity issue of TaO 2 F and improving the electrochemical reaction rate. The ratio of TaO 2 F nanorods to TaC nanosheets in the heterostructures can be controlled by adjusting the growth time, thus allowing the electronic properties of TaO 2 F@TaC to be regulated ...
