“…As far as we know,t remendous advances have been made on binary and ternary Pt-based nanocatalysts, while only very few reports are about quaternary nanomaterials. [13,14] The electrocatalytic performances of Pt-based nanomaterials are correlated with numerous parameters, including structure, morphology and size and so on. In recent years, one-dimensional (1 D) nanomaterials (especially NWs) have aroused great interestf or their unique properties.…”

Multicomponent Pt-based nanowires (NWs) have attracted widespread attentiona se letrocatalysts toward direct alcohol fuel cells because of their unique one-dimensional structure and high reactiond ynamics. Quaternary PtPdAuTeN Ws are designedv ia af acile template method, and NWs with ad ifferent composition are obtained by adjusting the feed ratio of metal precursors. The direct displacement reactiono fm etal precursors with Te NWsa nd the partial oxidation of Te lead to the formation of quaternary NWs. The rough surfacea nd abundant reactive sites deriving from the rearrangement of metal atoms on the Te NWs surface endow the PtPdAuTeN Ws with as uperior electrocatalytic propertya nd durability for methanol oxidation. The Pt 20 Pd 20 Au 10 Te 50 NWs display the largestm ass activity and best stabilitya mong all catalysts. The preparation of PtPdAuTeNWs could provideaviable strategy for the preparation of other multicomponent NWs.Supporting information and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.

The development of inexpensive, highly active and non-noble catalysts for the methanol oxidation reaction is extremely desirable for the practical use of direct-methanol fuel cells. Here, we have developed a template-free hydrothermal synthesis followed by calcination to produce highly active hybrid material of reduced graphene oxide (rGO) supported NiCo 2 O 4 (NiCo 2 O 4 /rGO) nano-rods as a non-expensive electro-catalyst for methanol oxidation. The electrochemical performance of the prepared NiCo 2 O 4 /rGO spinel catalyst was investigated by cyclic voltammetry (CV), chronoamperometry (CA) and electrochemical impedance spectroscopy (EIS) techniques. Impressively, the NiCo 2 O 4 /rGO showed greater electrocatalytic activity (78 mA/ cm 2 ) and stability during methanol oxidation in comparison to that of the commercial Pt/C catalyst, which was 3.11 folds higher than the commercial Pt/C (25.08 mA/cm 2 ). The NiCo 2 O 4 / rGO electrode also maintained its remarkable catalytic stability even after consecutive 500 cycles, which was~50 times higher than that of the commercial Pt/C. The overall electroactivity of NiCo 2 O 4 /rGO was remarkably enhanced by the synergistic effect between NiCo 2 O 4 and rGO. This may be due to the formation of mixed-valence cations of Ni 2 + and Co 3 + from the octahedral sites and high electron-transfer conductivity of rGO as well.[a] N.

Background: Certainly, there is a demand for stronger recognition of how nanoparticles can move through the cell membrane. Prostate cancer is one of the forcing sources of cancerrelevant deaths among men. Aim of the Work: The current research studied the power of prostate cancer cells to uptake a ternary nanocomposite TNT/CuFe 2 O 4 /Zn-Fe mixed metal oxides (MMO). Methodology: The nanocomposite was synthesized by a chemical method and characterized by a High-resolution transmission electron microscope, Field emission scanning electron microscope, X-ray diffraction, Fourier transmission infra-red, X-ray photoelectron spectroscopy, dynamic light scattering. Besides, it was implemented as an inorganic anticancer agent versus Prostate cancer PC-3 cells. Results: The results revealed cellular uptake validity, cell viability reduction, ultra-structures alterations, morphological changes and membrane damage of PC-3 cells. Conclusion: The prepared ternary nanocomposite was highly uptake by PC-3 cells and possessed cytotoxicity that was dose and time-dependent. To conclude, the study offered the potential of the investigated ternary nanocomposite as a promising prostate anticancer agent. BackgroundInvestigations have indicated that 25% of men are diagnosed with prostate cancer (PCa). 1 The clinical diagnostic approach is testing the prostate-specific antigen (PSA) level, where a concentration ˃ 4 ng/mL is considered a risk of biopsy. 2 The routine diagnostic technique is the digital rectal examination, and Multi-parametric-magnetic resonance imaging allows the potential diagnosis of PCa. 3 The distinct five stages of PCa are (zero) I, II, III, and IV, 4 and most cases of prostate cancer metastasis develop in the lymph nodes and the bones. 5 Choice of the treatment procedure, whatever surgery, radiation, hormone, Cryo-therapy, Vaccine, and Bone-directed treatment depends on the clinical stage, the age, and the general health of the individual. 6 The potential complications of the mentioned approaches are serious to consider. 7 The prostate size is the fundamental limitation of surgery, and 5 to 20% of cases suffer from stress incontinence after radical prostatectomy. Hormonal therapy leads to loss of libido, bone, and muscle mass. 8 Further, 30 to 50% experience erectile dysfunction after radiation therapy, 9 and urinary retention, urgency, and frequency are more common in Brachytherapy.
