Sunulan çalışmada, Ni katkısının yaş kimyasal yöntemle hazırlanan Fe2O3’ün yapısal özellikleri üzerine etkileri X-ışını kırınımı (XRD), Fourier dönüşümlü kızılötesi (FTIR), diferansiyel termal analiz (DTA), termogravimetrik (TGA) ve taramalı elektron mikroskopisi (SEM) teknikleri kullanılarak araştırıldı. XRD FTIR sonuçları her bir numune için Fe2O3 yapının oluşumunu destekledi. 4at.%Ni katkısı...

We have methodically investigated the structural, spectroscopic, local atomic structure and magnetic properties of aquatic $${\text{Zn}}_{{1{\mathbf{ - }}x}} {\text{Ni}}_{x} {\text{S}}$$ (0 ≤ x 0.04) nanocrystals. The structural study synthesized samples is observed by X-ray diffraction data with Rietveld refinement. Proficient decrease lattice parameters inter-planar spacing are determined on ...

Developing highly efficient platinum-group-metal-free electrocatalysts towards hydrogen oxidation reaction (HOR) under alkaline electrolyte is critical for the development of exchange member fuel cells. Herein, we reported synthesis boron doped Ni electrocatalyst (B-Ni/C) and its remarkable HOR performance, with a 10-fold mass activity enhancement compared that undoped catalyst. Experimental re...

Nickel-rich NMC (LiNi x Mn y Co 1−x−y O 2 , ⩾ 0.8) electrode materials are known for their great potential as lithium battery cathode active due to high capacities, low cost, and environment friendliness. However, these confront some technical challenges such structural, surface, electrochemical instability while different synthesis methods have large influences on morphology, structure, perfor...

The discovery of superconductivity in copper oxide compounds has attracted considerable attention over the past three decades. high transition temperature these compounds, exhibiting proximity to an antiferromagnetic order their phase diagrams, remains one main areas research. present study attempts introduce Fe, Co and Ni magnetic impurities into superconducting Y-123 with aim exploring behavi...

The properties of solid oxide fuel cell (SOFC) anode functional layers prepared by impregnation of ceria and catalytic metals into porous yttria-stabilized zirconia (YSZ) have been examined for operation at 973 K. By varying the thickness of the functional layer, the conductivity of the ceria-YSZ composite was determined to be only 0.015–0.02 S/cm. The initial performance of anodes made with ce...
