2024年9月24日 · Ni/Zn co-substituted copper ferrites (Cu 1−3x Ni x Zn 2x Fe 2 O 4) with a step interval of 0.01 and 0.0 ≤ x ≤ 0.06 were synthesized using the sol–gel method. The microstructural, elastic, and magnetic properties of the samples were investigated using Raman spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy (FTIR ...

2003年9月1日 · The thermodynamic parameters of the binary sub-systems, Cu–Ni, Cu–Zn and Ni–Zn, are taken from earlier SGTE-based assessments (modifying the Ni–Zn description slightly) and those of the ternary Cu–Ni–Zn system are optimized in this study by using the experimental thermodynamic and phase equilibrium data.

2020年8月31日 · In this paper, Cu-substituted NiZn ferrites with nominal compositions of (Ni 0.3 Zn 0.7) 1−x Cu x Fe 2 O 4 (0 ≤ x ≤ 0.4) were prepared by solid-state reaction method. Then, the structural, element composition, valence distribution, surface morphology and magnetic properties of the samples were investigated systematically.

2023年1月1日 · We report the fabrication of nickel-copper-zinc (NiCuZn) ferrites via a facile blowing-combustion method, where the grain size and morphology can be readily controlled by adjusting the sintering temperature.

2 天之前 · In this work, a rechargeable Li-CO 2 Mars battery is operated in a simulated Martian atmosphere using [EMIm] + [BF4]-ionic liquid (IL) as an additive in the dimethyl sulfoxide (DMSO)-based electrolyte and a spinel MFe 2 O 4 (M = Co, Ni, Cu, Zn) nanocomposite catalysts with conductive multiwalled carbon nanotubes support prepared by a single ...

2022年2月10日 · Therefore, the as-formed CuZn-Ni aerogel exhibited a much-improved catalytic activity and selectivity for CO generation with FE(CO) increased to 80% from 60%. This work gives insights into the surface adsorption–desorption characteristics underlying the activity and selectivity of electrocatalysts, which is of general importance for CO 2 RR.

2014年11月17日 · The revelation of the composition formulas for the Cu-(Zn,Ni) industrial alloys points to the common existence of simple composition rules behind seemingly complex chemistries of industrial...

2025年1月21日 · To obtain high-performance magnetic sheet with high initial permeability and low magnetic loss for wireless charging system, Ni–Zn–Cu ferrite ceramics with a chemical formula of Ni 0.6 − x Zn 0.4 Cu x Fe 2 O 4 (x = 0–0.30) were prepared by traditional solid reaction-sintering

2024年5月19日 · Ni-Zn-Cu多重纳米孪晶增强的肼氧化催化活性 Journal of Alloys and Compounds ( IF 5.8) Pub Date : 2024-05-19, DOI: 10.1016/j.jallcom.2024.174898

EPR光谱用作研究Cu（I）/ Cu（II）氧化还原对的补充方法。结果研究发现，即使在过量的其他金属离子（Co（II），Ni（II）和Zn（II））下，硫杂皇冠醚也优先结合痕量的铜。Cu（I）配合物的绝对缔合常数约为10（8）M（-1），而其他3d-金属阳离子则低约两个数量级。
