Nickel nanoparticles and solids using organic solvents

Structuring and characterization of a novel highly microporous PEI/BMI semi-interpenetrating polymer network

“…According to del Arco and co-workers [35], the two peaks are formed upon dissociative adsorption of ethanol on acidbase sites of the MgAlW/500 solid. Around this wavelength range (1055 cm K1 ), Cardenas and Acuna [36] observed the C-O stretching in primary saturated alcohol adsorbed on Ni. Therefore, the significant increase in these two peaks might be attributed to additional substituted ethoxy groups or/and existence of coordinated ethanol in the PEI-BMI-EtOH S and L membranes.…”

Assembling Nanometer Nickel Particles into Ordered Arrays

“…The UV/Vis spectrum of the so-synthesized Ni-MPC shows some weak absorption in the range of 300 ± 700 nm, but no peaks were revealed: This is consistent with other, previous reports. [22,23] …”

Synthesis and characterization of Fe, Co, and Ni colloids in 2-mercaptoethanol

“…In contrast, Fe is stable but no to the same extent as other metals due to the higher oxidation potential of Fe over Co and Ni. 19,21…”

“…In contrast, Fe is stable but no to the same extent as other metals due to the higher oxidation potential of Fe over Co and Ni. 19,21 The surface energy of a nano metal is different if their sizes are different. 21,22 This is due to quantum size effect, which is relevant in the nanotechnology materials.…”

“…19,21 The surface energy of a nano metal is different if their sizes are different. 21,22 This is due to quantum size effect, which is relevant in the nanotechnology materials. 23,24 The colloidal dispersions are systems that tend to produce clusters of low energy state.…”
