“…Higher amounts of WC contamination in the Ni sample during MM, which is also known to inhibit grain growth by possible pinning effects of WC particles [27,28]. In any case, it is obvious that sintering causes a tremendous amount of grain growth, which is consistent with the reported literature about conventional sintering of Ni powders [29,30]. Moreover, as also seen in SEM micrographs presented in Randle et al [31] reported that twin formation in Ni can take place independently of grain growth and twins have their own kinetics twin nucleation is accomplished.…”

“…The phenomenon of NiO nanowall growth following recrystallization at the grain boundaries has been well documented in the previously report [ 24 ]. For example, Upadhyay and colleagues [ 25 ] studied the effect of sintering temperature on grain boundary character distribution in pure nickel. They report on observations that the grain boundary distribution and grain growth are correlated well with the accompanying microstructural changes.…”

The nanosized effects of short-range multimagnon excitation behavior and short-circuit diffusion in NiO nanowalls synthesized using the Ni grid thermal treatment method were observed. The energy dispersive spectroscopy mapping technique was used to characterize the growth mechanism, and confocal Raman scattering was used to probe the antiferromagnetic exchange energy J2 between next-nearest-neighboring Ni ions in NiO nanowalls at various growth temperatures below the Neel temperature. This study shows that short spin correlation leads to an exponential dependence of the growth temperatures and the existence of nickel vacancies during the magnon excitation. Four-magnon configurations were determined from the scattering factor, revealing a lowest state and monotonic change with the growth temperature.PACS: 75.47.Lx; 61.82.Rx; 75.50.Tt; 74.25.nd; 72.10.Di

Foam materials are very light, but compared with bulk materials, their strength is quite low because of their random structures. Natural lightweight materials such as bone, is a cellular solid with optimized structure. In this research, silica-nickel oxide (SiO2-NiO) foams were fabricated by a well-known method which is replication method. The compositions of SiO2-NiO foams consist of 55 wt.% of silica (SiO2) powder and 10 wt.% of nickel oxide (NiO) powder. SiO2 and NiO powders were mixed together with binders; polyethylene glycol (PEG) and carboxymethyl cellulose (CMC) to prepare slurry solution for replication of polyurethane (PU) sponge which functioned as the template. 10 wt.% of SiO2-NiO foams sintered at different temperatures; 1000 °C, 1100 °C, 1200 °C and 1300 °C. Morphology of 10 wt.% of SiO2-NiO foams such as the structure of foams and particles distribution were studied by using scanning electron microscopy (SEM).
