Structural investigations of oxidative behavior on nanocrystalline nickel

Synthesis and magnetic properties of nickel nanoparticles deposited on the silicon nanowires

“…Normally, the influence of nickel oxide was seldom and negligible. Meanwhile, the magnetic measurements stated below show that the exchangebias effect [24] was not found, indicating that NiO had not affected the magnetic properties of Ni/SiNWs [27,28]. The data implies that the face-centered-cubic, less oxidized Ni can be obtained under the current synthesis conditions.…”

Role of surface oxidation on the size dependent mechanical properties of nickel nanowires: a ReaxFF molecular dynamics study

“…Understanding oxidation phenomena and their effects on the mechanical deformation mechanism is currently an active area of research, and has caused immense interest and impact in science, engineering, technology, and most importantly in the fabrication of new nano materials with desired specific properties. [1][2][3][4][5][6][7][8][9][10] In particular, reactive metallic nano materials readily oxidize during the industrial manufacturing, handling, and measurement processes, due to the high contact surface area with reactive oxidizers. 1,3,8,9 As a consequence, the desirable (modification) or undesirable formation of native surface oxidation layers on nano materials protects the metal cores from contact with the outer surroundings, as well as leads to significant changes in the chemical, 2,3,6,7 mechanical, 10 electrical, 6 magnetic 2,5,6,10,11 and optical 12 properties.…”

The free surface of the oxidized shell layer of the reactive nano crystalline materials plays a direct role in controlling and manipulating the physical, chemical and mechanical properties of these materials, which mostly depend on the nature of surface defects, their density, thickness, etc.…”
