“…In order to further verify the attribution of the A / A ′ signal, the LiF-CaF 2 electrolyte was prepared according to the molar ratio of LiF:CaF 2 in the LaF 3 (80 wt %)-LiF-CaF 2 electrolyte, and CV experiments were carried out under the same conditions. In the red solid curve of Figure a, there is only one redox signal a / a ’ which is related to the redox of metal Li, while the deposition potential II of metal Li occurs roughly at −2.06 V . It can be clearly seen that there is a significant difference between the deposition potential in the black dotted curve and the red solid curve.…”

Electrolyte is considered to be one of the key factors affecting electrolysis in the rare earth and their alloys industry. Generally, the fluoride system is chosen as the electrolyte for industrial production. However, the molten salt electrolysis method for fluoride-oxide systems is not well understood and has not been systematically studied at this stage. In order to supplement this part, lanthanum (La) ions have been chosen as the research object in this paper to systematically investigate the preparation of La−Ni alloy from LaF 3 −LiF-CaF 2 −La 2 O 3 molten salt. A series of electrochemical methods were used to investigate the mechanism and kinetic properties of La(III) reduction on W and Ni electrodes. The electrochemical reduction properties and kinetic parameters of La were obtained. La−Ni alloy was prepared by potentiostatic electrolysis, and it was verified by detailed analysis through characterization methods. On this basis, LaNi 5 intermetallic compound was successfully prepared on Ni electrode. This study provides valuable theoretical guidance for the development of La alloy preparation with fluoride salt systems in industry.

“…PPD and PPT are both dammarane tetracyclic triterpene saponins, and the main difference in structure is whether there is a hydroxyl substitution on the carbon at position 6 (Pan et al, 2018). Moreover, in the anti-BC research of ginsenosides, it mainly revolves around PPD and PPT types ginsenosides, and in details, the structure is mainly different in groups on the carbon at positions 3, 6 and 20 (Figure 1).…”

Breast cancer (BC) is one of the most common malignant tumor, the incidence of which has increased worldwide in recent years. Ginsenosides are the main active components of Panax ginseng C. A. Mey., in vitro and in vivo studies have confirmed that ginsenosides have significant anti-cancer activity, including BC. It is reported that ginsenosides can induce BC cells apoptosis, inhibit BC cells proliferation, migration, invasion, as well as autophagy and angiogenesis, thereby suppress the procession of BC. In this review, the therapeutic effects and the molecular mechanisms of ginsenosides on BC will be summarized. And the combination strategy of ginsenosides with other drugs on BC will also be discussed. In addition, epigenetic changes, especially microRNAs (miRNAs) targeted by ginsenosides in the treatment of BC are clarified.

“…ΔG of reaction ( 6) is less than zero only when the temperature is above 1200°C, which is consistent with the XRD results that the crystal phase MoB was detected at 1400°C (Figure 5). According to the thermodynamic parameters of Mo 4.8 Si 3 C 0.6 in related literature [39] and the thermodynamic parameters of other reactants and products in reactions ( 4) and ( 5) from HSC chemistry software, ΔG of reactions ( 4) and ( 5) at 1200°C and 1600°C can be calculated respectively. The calculation results of ΔG of reaction (4) at 1200°C and 1600°C are −807.34 and −712.21 kJ mol −1 , and those of reactions ( 5) at 1200°C and 1600°C are −804.02 and −716.77 kJ mol −1 .…”

Various thermal protective ablative materials (TPAM) have been extensively studied. However, there are few reports on the thermal stability, the ablation properties and ceramisation of vitreous silica fabric reinforced boron phenolic resin composites with an incorporation of MoSi 2 (VMBPR) and their bending strength after ablation. At this work, the above performances of the composites were characterised and analysed. Results reveal that the addition of MoSi 2 decreases the graphitisation temperature of glass carbon of BPR pyrolysis, promoting the formation of a more ordered structure of the glassy carbon during pyrolysis. Furthermore, compared with the composites without MoSi 2 (VBPR), the linear and the mass ablation rate of VMBPR composites decrease by about 94.46% and 39.09%, and its room temperature bending strength after static ablation at 1400°C for 20 min is more than twice that of the fused fibre aggregation formed by VBPR composites. This is attributed to the ceramisation reaction of VMBPR composites at high temperature.
