Synchrotron XRD and structure evolution of 4Hb-TaSe 2 at high pressure. (a) Representative powder XRD patterns between 1.5 and 40.8 GPa (run 1). (b) Pressure-dependent normalized …

2004年1月1日 · Single-phase layered nanocomposite containing 4Hb-TaS 2 and poly (ethylene oxide) [PEO] has been first synthesized by using the exfoliation–adsorption technique. It has …

A second run of high-pressure XRD ( Figure S10) and Raman-scattering measurements ( Figure S11) undoubtedly confirms the iSPT of 4Hb-TaSe 2 at ∼10 GPa and the transition from quasi …

2023年3月6日 · A second run of high-pressure XRD (Figure S10) and Raman-scattering measurements ( Figure S11 ) undoubtedly confirms the iSPT of 4 Hb -TaSe 2 at ∼ 10 GPa …

XRD spectrum. Only peaks belonging to the (00l) family of 4Hb-TaS 2 are present, confirming that the sample is a single-crystal and not a phase-separated mixture of 1T and 2H phases. Fig. …

2024年4月10日 · The samples are characterized by XRD, TEM, EDS and magnetization measurements (Supplementary Figs. 8 and 9). Se in 4Hb crystals is used to stabilize the 4Hb …

1973年8月1日 · A new polymorph of the layered compound tantalum disulfide, 4Hb-TaS 2, has been prepared in single crystal form. Measurements of magnetic susceptibility, electrical …

We study 4Hb-TaS, which naturally realizes an alternating stacking of 1T-TaS and 1H-TaS structures. The former is a well-known Mott insulator, which has recently been proposed to …

在这里，我们将扫描隧道显微镜和角度分辨宏观传输相结合，以研究候选手性超导体 4Hb-TaS2。 我们揭示了隧穿电导中的准周期一维调制，并伴有两倍对称超导临界场。

1, 3 and 5 %wt of 4‐hydroxybenzoic acid (4HB) was successfully loaded into sodium alginate and polyvinyl alcohol‐based hydrogel composite for enhancement of antioxidant activities. …
