2024年8月28日 · In this study, we investigated a two-step protocol for uniform size production of thin-layered h-BNNS. By carefully manipulating the crystallization degree during synthesis of h-BN powder and employing subsequent hydrothermal treatment, we successfully obtained h-BNNS with an even thickness of only a few atomic layers.

XPS survey (Fig. 5a) shows the coexistence of B and N as main elements and O and C as impurities in the samples. The B/N ratio is about 1.07, close to the reported values [16,34]. In the B1s...

2025年2月7日 · The survey XPS spectrum indicates that following MnFe 2 O 4 modification, the surface of BNNS exhibits characteristic peaks corresponding to Mn 2p and Fe 2p. Additionally, the U-BNNS sample reveals a significantly higher content of N and O compared to unmodified BNNS, confirming alterations in the elemental composition due to the modification ...

2017年8月1日 · Chemical analyses using both spectroscopy techniques (XPS and Raman) confirm that Ar/N 2 and Ar/O 2 plasma treatments of the BNNS samples are more effective toward incorporation of oxygen functional groups onto the BNNS than either as-prepared or Ar/NH 3 plasma-modified BNNS samples.

Oxygen and carbon peaks shown in survey plot most likely resulted from the exposure of f-BNNSs to air or during the XPS measurement groundwork. The deconvoluted binding energies of B 1s at 189.6...

Depth-dependent X-ray photoelectron spectroscopy (XPS) measurements reveal the presence of a layer of adsorbed oxygen at the NFO/Gr and NFO/hBN interfaces.

2022年8月1日 · Trp and Phe display higher functionalization degree and dispersibility of BNNS than Arg and Lys thanks to the additional π-π interactions between the aromatic groups and BNNS. Moreover, both BNNS-Trp/EP and BNNS-Phe/EP exhibit higher cross-plane thermal conductivity of 2.1 and 1.96 W m −1 K −1 at 30 wt% filler loading.

2020年3月25日 · 这和普通的xps图有什么区别？ 还有，为什么B 1s的谱峰长得就和基线一样，小峰特别多，感觉信噪比很低；而C 1s谱和N 1s谱就很平滑，很好看呢？ 谢谢

2017年6月9日 · X-ray photoelectron spectroscopy (XPS) was performed to probe the change in the BE of Pt to further investigate the charge transfer between Pt and...
